Title:Lightweight Ballistic Exhaust Grille with Directional Capabilities and Reduced Thermal Signature
Abstract:The Expeditionary Fighting Vehicle (EFV) has two aft mounted exhaust grilles that interface the heat exchangers to the external environment. The current grille design suffers from competing requirements which render its performance less than optimal. In this Phase I project, Infoscitex proposes to conduct research into innovative composite materials and fabrication methods that will enable a grille to meet weight, airflow, ballistic and thermal emissivity requirements, as well as allowing directional capabilities. Following materials selection and evaluation, a first generation design will be created. Subsequently, a cost-benefit analysis will be performed on the design that analyzes the projected performance and costs of ownership. A design will be pursued that allows the new grille to be integrated with the existing housing and mounting flanges.

Title:Ballistic Exhaust Grille
Abstract:New World Associates proposes to develop an exhaust grille for the Marine Corps EFV (Expeditionary Fighting Vehicle) that improves performance and maintains required ballistic protection. The issue with the current design for the EFV is that the exhaustgrille is a heavy system that does not allow flow control (IR signature suppression) with adequate ballistic protection. The modified design will evaluate several design options and will focus on the following primary design criteria: A) Obtain specified ballistic performance; B) Optimize airflow vs. pressure drop characteristics; C) Reduce vehicle infrared signature; D) Minimize weight and manufacturing costs. During Phase I of the proposed program, tasking will include research into available materials that optimize weight reduction and ballistic protection requirements. During this phase, several design concepts will be proposed and evaluated with respect to the EFV performance specification (EFV S/SS Specification Rev J. dated 10 August 2006). New World will utilize its extensive background of ballistic protection of vehicles and airflow design and analysis to solve the proposed problem.

Title:Dual Mode Controlled Ricochet Low Loss EFV Cooling Grille(1001-046)
Abstract:Triton Systems Inc. in collaboration with the Charles Stark Draper Laboratory will develop a controlled multiple ricochet ballistic grill for the USMC EFV that minimizes the required vane thickness and associated pressure drop through the grille. Two-stage baffling of the incoming threat allows the flow direction to be modified while still ensuring at least three strikes and downward exiting fragments. Advanced high hardness Titanium and Stainless Steel alloys are used to tailor the ricochet angles of the threat projectiles, while maintaining integrity against corrosion degradation in the salt air and water environments. Low emissivity coatings on the metallic elements minimize the vehicle IR signature increments. The controlled ricochet design will allow reductions of at least 50 pound in each of the (250 lb.) current ballistic grilles aboard the EFV. During the Phase I project, Triton will fabricate and ballistic test samples of the projectile baffles to validate the threat protection performance, while C.S. Draper Laboratory will perform extensive CFD and thermal response tradeoffs on the strawman grille design to guide the grille design and validate throughput and thermal performance. During the Phase II Triton will fabricate a prototype ballistic grille for installation and operational testing aboard an EFV.

Title:Development of Biological Obscurants
Abstract:The DoD has funded a number of nanotechnology based obscurant projects. Recent studies have shown the potential health and environmental risk associated with nanoparticle exposures. Development of biologically based obscurants could eliminate these shortcomings by providing multi-spectral capabilities, environmental-friendly (i.e., biodegradable), non-pathogenic constituents and non-toxic by-products. GXI and Dr. James P. Chambers of the University of Texas at San Antonio propose to develop biological obscurants for battlefield applications based on the use of bacteriochlorophylls. In Phase I, GXI and Dr. Chambers will conduct spectroscopic investigations of bacteria containing bacteriochlorophyll b with tetrapyrrole pigments to demonstrate the feasibility of using chlorophyll compounds as obscurants. We will also investigate the use of combinatorial techniques to alter the protein microenvironment near the tetrapyrrole ring and thus tune the absorption spectra to provide multi-spectral capabilities. The rational for use of chlorophyll compounds as an obscurant is based on the broad range of spectral absorption using chlorophyll derivatives. Absorption peaks coincide well with specific areas of military interest including: (1) the visible range; (2) night vision ranges of 700 to 800 and 900 nm for 3rd generation imaging technology; and (3) the 1064 nm range for most smart bomb and missile laser guidance systems.

Title:Shelf-Stable Red Phosphorus
Abstract:Smoke-producing munitions such as mortars, smoke pots, and hand grenades are an important class of ordnance employed by the US military in both training and mission scenarios. These devices serve a number of vital functions including smoke screening for vision obscurance and marking of targets. A number of smoke-producing munitions used by the USMC rely upon red phosphorus (RP) to generate a smoke that provides screening in both the visible and IR spectra. Although RP performs exceptionally, its susceptibility to degradation during storage to form phosphine and other hazardous materials has risen concerns for personnel health. In this Phase I SBIR program, Infoscitex Corporation (IST) proposed to enable the continued use of RP through development of a novel coating system that will render it shelf-stable. IST will develop an inorganic coating system that will address shortcomings of previous attempts to stabilize RP, and will ensure that performance of existing smoke-producing munitions is maintained.

Title:Replacement of Red Phosphorus in Smoke Producing Munitions
Abstract:Future combat scenarios requires a red and/or white phosphorus alternative as a multi-role munitions filler for obscuring, screening, marking, incendiary and thermobaric applications. Currently, red and white phosphorus filled munitions are successfully being deployed in combat, especially in "shake and bake" missions in Fallujah. However, processing, deployment, storage and overall safety concerns primarily limit the utilization of red and white phosphorus. Especially when stored, phosphorus decomposes to phosphorus pentoxide and then phosphoric acid in moist environments. In lieu of safety concerns and cost ineffectiveness in producing red and white phosphorus, Powdermet Inc. proposes to use reactive fuel/oxidizer microcomposite obscurants with "nanolaminate" fuel/stabilizer/thermite coatings produced by Fluidized Bed Chemical Vapor Deposition (FBCVD) and fluoropolymer press coatings as a suitable/superior alternative for red and white phosphorus fillers for current and future munitions. The particle size, composition, and intimate mixing of fuel and oxidizer during spray drying, FBCVD, and fluoropolymer press coatings will yield favorable combustion and reaction rates in order to maximize smoke production, colored smoke production, exothermicity, and blast/expansion pressure. Complete characterization will be performed to ensure that the correct properties are achieved.

Title:Replacement of Red Phosphorus in smoke producing munitions
Abstract:Current smoke producing munitions posess significant total obscuring power (TOP) but suffer from the drawbacks taht they are both toxic and corrosive towards military personnel and hardware respectively. A burgeoning need therefore exists for alternative obscurants which are benign as well as posess high TOP properties. Polyphenol derivatives represent one such promising class of materials meeting this criteria and will be developed and characterized during this proposed Phase I SBIR research program.

Title:ADaptive Augmented Reality based Assistance System (ADARAS)
Abstract:Augmented Reality (AR) has been proposed as a means of assisting technicians tasked with maintaining weapons platforms. Despite its various benefits, the effectiveness of AR as a means of improving performance dictates that the traditional challenges associated with scene recognition and information presentation be addressed. Hence, we propose to design and demonstrate the feasibility of the ADaptive Augmented Reality based Assistance System (ADARAS), which utilizes unique scene recognition capabilities coupled with customized information presentation techniques to significantly improve the troubleshooting capabilities of the junior maintainer. ADARAS uses intelligent agents to customize the information presented in AR space, which maximizes the utility and effectiveness of the presented information based on the cognitive limitations and learning capacity of the individual maintainer. The proposed system also encompasses unique scene recognition algorithms that jointly work to ensure that the maintainer's attention is allocated to the relevant problem space thereby maximizing the probability of success.

Title:Advanced Equipment Maintenance Using Revolutionary Augmented Reality Technology
Abstract:The Terrestrial Augmented Reality Maintenance Assistance (TARMA) will leverage Cybernet Systems existing Shipboard Wireless Maintenance System (SWMA), head mounted display systems, and gesture recognition software to create a portable computing platform for augmented-reality based vehicle maintenance. This system will use small, magnet-mounted, light emitting diodes (LEDs) beacons as reference points for the projection of schematics into the viewing region of the head mounted display. In addition to schematics and Interactive Electronic Technical Manuals (IETMs) and condition-based maintenance systems the head mounted display will present data from a suite of peripheral devices including digital multi-meters, bar code scanners, and RFID readers. Cybernet will also apply our gesture recognition system to the system's forward looking camera to provide a maintainer aptitude evaluation. This aptitude evaluation could potentially be used in level IV and V by IETMs to provide tailored maintenance specifications. Using the SWMA's existing collaboration suite our system will be able to provide remote support from subject matter experts to in-field maintainers.

Title:Augmented Reality Maintenance System (ARMS) for Complex Military Assets
Abstract:Currently, equipment maintenance requires highly trained individuals and is labor intensive, expensive and inefficient. The Marine Corps and DOD use written technical manuals and Interactive Electronic Technical Manuals (IETM) to direct technicians through complex maintenance procedures for land vehicles, radar systems, radio communications systems, and ground-based weapon systems. Recently, the internet has made it possible to retrieve relevant maintenance data more quickly using computer search programs. However, technical manuals are still time consuming and tedious to use, and substantial training is needed to extract the appropriate data, understand the technical details for troubleshooting defective components, and the performance of critical maintenance and repairs. RMD, in collaboration with Dr. Steven Feiner at Columbia University, proposes a revolutionary new technology for equipment maintenance based on Augmented Reality (AR). The AR-based maintenance system will guide the equipment maintainer through the entire maintenance process, from the identification of defective components to the detailed repair methodology and the functional test sequence. The Augmented Reality system will be graphics intensive and interactive, making it simple and highly intuitive to use. It will augment the abilities of the technician by providing the type of guidance normally associated with an expert human trainer.

Title:Fused Reality(tm) Maintenance System
Abstract:The solicitation for this topic stresses the need for alternative approaches to conducting equipment maintenance. A PC-based technology called Fused Reality(tm) created by Systems Technology Inc. (STI) currently employs live video capture, real-time video editing, and virtual environment simulation to enable the fusing of physical images into a virtual scene, which can then be moved within that scene. Fused Reality(tm) uses chromakey to identify areas of interest in the physical scene. One of the key innovations of the proposed Fused Reality Maintenance System (FRMS) is modifying Fused Reality(tm) to use machine vision for identifying real objects so that they can be fused into and moved within the virtual environment. Other novel innovations include the integration of novel 3D interfaces (such as image-based head tracking) with a 3D modeling software tool such as Solidworks, and using Solidworks to generate the virtual scene layer for use with Fused Reality(tm). In order to provide an integrated solution for the maintainer's challenges, the system will employ state-of-art technologies including: machine vision recognition, voice recognition, neural networks, and knowledge-based expert systems. Novel design in human-machine interface design will balance cognitive workload with task execution. Key issues pertaining to diagnostics, component replacement, and logistics are addressed.

Title:Non-Line-of-Sight Coating Of Turbine Airfoils
Abstract:Thermal barrier coatings (TBC) are desired to improve the durability of hot-section engine components. Currently, TBC top coats are applied onto turbine components using an electron beam physical vapor deposition (EB-PVD) process. A key drawback of this approach is that it can only effectively coat surfaces in the line-of-sight of the vapor source. The advent of advanced engine designs containing complex components with many hidden surfaces have resulted in a need for TBC deposition techniques which can effectively deposit high quality coatings onto the non line-of-sight (NLOS) regions of components. In this work, we will use novel coating techniques that increase the growth rate of TBC coatings in NLOS regions and also result in the required coating microstructure. The proposed Phase I effort will demonstrate the key performance attributes of the process by applying TBCs onto superalloy substrates aligned NLOS to the vapor source. This will lead to a follow-on Phase II program focused on using the new deposition process to apply TBC coatings onto real aircraft components having NLOS region. The end result will be process the can apply next generation TBC coatings onto a wider range of complex engine components in a cost effective manner.

Title:Demonstration of Non-Line-of-Sight TBC
Abstract:Advances in turbine materials resulting in high strength and lightweight metallic and ceramic components have allowed for high efficiency, high power density, compactness, and low emissions. Current technology turbine blades are comprised of single crystal nickel superalloys in combination with ceramic thermal barrier coatings (TBC). Typical TBC composition consists of an aluminum rich bond coat, thermally grown oxide (TGO), and yttria stabilized zirconia (YSZ). These coatings have limited durability and constrain peak engine temperatures due to non-uniform coating thickness and susceptibility to crack propagation. Non-uniformities within the thickness are caused by line-of-sight coating applications typical of current industry standards. To address these shortcomings, Mainstream will rely on its expertise in nano-technology and chemical vapor deposition techniques to demonstrate a non-line-of-sight method for producing a strain-tolerant thermal barrier coating. The Phase I effort will characterize the mechanical properties of the nanocomposite coating, demonstrate the feasibility of the inclusion of nanostructures within a ceramic matrix, and validate the strain tolerance via thermal fatigue and thermal shock experiments.

Title:Non-Line-of-Sight Coating Of Turbine Airfoils
Abstract:The current state-of-the-art techniques for thermal barrier coatings (TBCs) are typically line-of-sight. Therefore the achievable coating thickness distributions on complex shaped parts are limited and inconsistent. The geometry of the turbine airfoils is getting more complex with each design making the line-of-sight processes for TBC less desirable. UES Inc in collaboration with Penn State University proposes to design a hybrid hydrothermal-electrophoretic process as a non-line-of-sight technique for TBC. The feasibility of the proposed technique will be demonstrated in a laboratory environment. Durability of the TBC fabricated from the proposed technique will be evaluated and compared with the state-of-the-art TBC coating. In Phase II, a prototype hybrid hydrothermal-electrophoretic system and the related process capable of producing TBC coating on engine hardware will be developed.

Title:Solid-State High-Efficiency Radar Transmit Module
Abstract:The primary objective of Phase 1 is to establish a design baseline for a very high power and highly efficient GaN amplifier. Design objectives for the Class E/F power amplifier are to achieve 100 watts power output at >60% PAE over 405-450 MHz. Hittite will synthesize Class E, Class F and inverse class F and then select the optimum load and source networks to achieve highest reasonable efficiency. Hittite will use a very thermally conductive hybrid package. That packaging is a highly cost effective proven mass production packaging technology. Hittite will identify the optimum process for MMIC implementation of the amplifier, and then provide modeling results of the core technology demonstrating the RF, DC and thermal characteristics of the amplifier. From this selected MMIC core technology we will build and demonstrate a hybrid version of this amplifier. The hybrid version will use proven 50V GaN devices and a proven design approach. In the option Hittite will also design a high K dielectric power combiner, and the first iteration of the GaN 100 watt PA MMIC. Hittite has designed over 20 GaN PA's for numerous DOD customers demonstrating > 70% PAE GaN PA's.

Title:High resolution SAR detection/estimation in alpha-stable interference
Abstract:Ambiguity function analysis of a new design concept for side-looking synthetic aperture radar (SAR) indicates that range-rate resolution can be improved by at least a factor of ten while removing range-rate/azimuth ambiguities, and that azimuth-rate resolution can be improved by at least a factor of five. The proposed work is (1) to further verify these improvements via a realistic simulation based on actual SAR data for upwind and downwind conditions, (2) to investigate the effects of nonlinear, alpha-stable detection/estimation procedures on the improved system, and (3) to mitigate the deleterious effects that are likely to occur when nonlinear operations are applied to a system that relies heavily on linear superposition for range compression, azimuth compression, and velocity hypothesis testing operations.

Title:Stable signal processing for improved-performance real-life radar
Abstract:Robust Analysis has pioneered the development of extremely efficient algorithms for radar signal processing in heavy-tailed clutter, based on cutting-edge numerical methods derived from the theory of stable distributions. Robust Analysis is the developer of STABLE, the first commercially available software library for stable data processing. STABLE incorporates a Signal Processing Toolbox with comprehensive filtering solutions for impulsive signals. This toolbox is at the core of one of our most important innovations: the stable matched filter. Although still preliminary, STABLE already has a Radar Systems Toolbox which incorporates a suite of stable matched filtering routines, and a battery of applications of these routines in SAR imaging and radar target detection. The goal of this SBIR is to extend the reach of the STABLE software and its Radar Systems Toolbox to provide a comprehensive industrial-quality solution for radar engineering in heavy-tailed environments. For Phase I, we will develop an adaptive version of the stable matched filter that ensures real-time applicability of the technology in real-life challenging scenarios of interest to the Navy. We will also develop speed optimizations that accelerate the algorithms and enable real-time performance. SAR and STAP applications of the technology will also be investigated.

Title:Modeling Algorithms for Unmanned Aircraft/Weapons Management Systems
Abstract:Unmanned Aerial Systems are rapidly evolving in each of the armed services from their traditional Intelligence, Surveillance, and Reconnaissance missions to platforms with a mix of payloads and weapons. All indications are that this evolution will continue and the future of Fire Scout will include an assortment of weapons and other mission payloads. Each of these future integration programs would be time consuming and expensive if traditional acquisition and integration approaches from the era of manned aircraft were adopted. Torch Technologies, Inc. has partnered with General Dynamics Advanced Information Systems to propose a robust and credible approach to weapon and mission payload integration that is based on the Object Management Group (OMG) Model Driver ArchitectureT (MDA) Initiative. the Torch Team proposes a complete systems engineering approach that is based on the principles of MDA. It is a solution that separates functionality from architecture so that it can be maintained and reused, even across multiple architectures. It is a solution that will map the functionality to the platform processing architecture based on the Fire Scout Program Manager's safety, reliability, security, real-time and resource consumption requirements, and permit early and cost effective verification and validation that those requirements will be met.

Title:Modeling Algorithms for Unmanned Aircraft/Weapons Management Systems
Abstract:Current methodologies for integration of weapons on unmanned and manned aircraft platforms and the associated control software development/integration typically result in a lengthy and expensive integration process. Problems are frequently discovered in the hardware/software prototyping or flight test program phases, when they are difficult and expensive to fix and likely to result in significant program perturbations. Potential safety issues that were not forecast can also be encountered. Recent studies by both U.S. and NATO organizations have identified structured modeling technologies and processes (including the evolving Model Driven Architecturer, or MDAr, process supported by commercial industry) as having a high potential to significantly mitigate the identified problems, if appropriately adapted and incorporated into the platform avionics and weapon integration design approach. To support such a model-based process, flexible modeling algorithms for weapon control systems and associated weapon employment functionality need to be developed in languages such as the Architecture Analysis and Design Language (AADL) and Executable Unified Modeling Language (xUML). The effort proposed here would investigate the requirements and feasibility of a set of appropriate modeling algorithms for this purpose, and define a proposed approach for development and demonstration of prototype algorithms in a follow-on Phase II program.

Title:Advanced Prognostic and Health Management (PHM) and Model Based Prognostic Useful Life Remaining Capabilities for Aircraft Tactical Information and Communication Systems
Abstract:Frontier Technology, Inc. (FTI) will demonstrate the feasibility of developing prognostic models that can predict current health state, future failure and remaining useful life (RUL) for electronic systems with focus on aircraft communication, navigation and identification systems (CNI) and their components. FTI will combine principles of real-time prognostic health management that analyze system health states with Reliability Centered Maintenance that estimate RUL and recommend appropriate corrective action. FTI's research adapts successful system-level prognostic and RCM technologies to installed electronics systems using data-derived statistical models that function with existing data sources and are easily extended to varying system configurations. The research will: * Maximize use of existing sensors, parameters and data sources from installed systems. * Create models of healthy systems using variances from optimum system conditions to detect incipient faults. * Identify the fault to failure progression and estimate component or system RUL. * Notify system users of fault detection, RUL and suggested action/areas of investigation This Phase I effort extends FTI's research into prognostic assessment of system health. Phase II will demonstrate prototypes of the models developed during Phase I and will identify limitations and areas requiring investigation in applying the technology to specific electronic system configurations.

Title:Advanced Prognostic and Health Management (PHM) and Model Based Prognostic Useful Life Remaining Capabilities for Aircraft Tactical Information and Communication Systems
Abstract:Prognostics and health management technologies are critical for detecting impending equipment failures and enabling a proactive decision process for maintaining or replacing components before actual failures occur. This capability is particularly critical to the Joint Strike Fighter given the goals for high affordability and mission readiness. Achieving the gains in maintenance decision making, safety, system availability, productivity, and cost savings, depends on the PHM system's ability to predict accurately the remaining useful life of the aircraft mission systems at any time. This effort investigates the development of advanced prognostic models to enable the predictive capability of the JSF PHM system. The effort considers the application of real-time, sensory- updated, residual life based models for estimating and predicting the remaining useful life of the JSF Communication, Navigation and Identification systems. The effort researches and characterizes the detectable impeding faults, and the physical phenomena, of the system and component degradation processes. The expected patterns in the sensory information and the techniques required to model the evolution of the component degradation process, in order to predict the remaining useful life of a system, are identified. A system definition, capability implementation plan, and a proof-of-concept demonstration of the approach are part of this effort.

Title:Advanced Prognostic and Health Management (PHM) and Model Based Prognostic Useful Life Remaining Capabilities for Aircraft Tactical Information and Communication Systems
Abstract:Ridgetop will create algorithms and models for Prognostics/Health Management (PHM) on radio-frequency (RF) components used in Communication, Navigation, and Intelligence (CNI) systems. A key focus of this work is adaptation of proven time-domain statistic analysis techniques - Multivariate State Estimation Technique (MSET) and Sequential Probability Ratio Test (SPRT) - to the frequency domain, exploiting the increased sensitivity and robustness of the statistical approach with the computational economy achieved with Fourier-transform or frequency-space algorithms. These models will be proven on representative CNI hardware chosen by Ridgetop's Prime Contractor Partner (Raytheon) with input from the JSF Program Office. The chosen hardware will have a history of high failure rates and intermittent faults, and the prognostic models will be driven by existing parameters and measurands. Ridgetop's proactive IRAD for this proposal indicates that subject components can be chosen which represent both legacy (ageing aircraft) and emerging technology, to maximize return-on-investment (ROI) to the warfighting customer. An optional effort will focus on one complex, high-failure rate CNI component such as the Traveling-Wave Tube (TWT). Ridgetop's proposed work plan includes demonstrated detection of intermittents which complicate the diagnosis of faults and prediction of remaining useful life for critical aircraft systems.

Title:Compact Diode Laser-based Magnetometer
Abstract:This Small Business Innovative Research Phase I project will combine ultra-sensitive absorption spectroscopy detection techniques and alkali atom optical gas pumping to produce an innovative Compact Magnetic Detection Set (CMDS). The CMDS will utilize a self oscillating magnetometer to produce a robust, compact, light weight and low power sensor for Navy applications of air anti-submarine warfare (ASW) and land-based IED detection. Current CMDS systems are too large, heavy and consume too much power for many aircraft platforms, including the MH-60R Romeo helicopter and the FireScout VTUAV. Physical Sciences Inc. (PSI) will create a system design for an optically based alkali atom CMDS that will achieve performance specifications equivalent to the AN/ASQ-233 and AN/ASQ-508 systems using innovative, ultra-sensitive detection techniques packaged into a compact, light, low power architecture. During the Phase II effort the CMDS will be fabricated and tested to verify operation and performance limits. The proposed effort leverages PSI's experience demonstrating sensitive magnetometers with PSI's successful line of commercial, tunable diode laser absorption spectroscopy hardware systems. PSI has an extensive and proven history of developing and delivering optically based sensor solutions for demanding commercial and Navy Mil-Spec applications.

The CMDS laser magnetometer is an innovative light-weight, compact, low-power, high-sensitivity instrument capable of measuring scalar DC and ELF magnetic fields with sensitivity better than 0.3 pT/?aHz in the frequency interval 0.01-100 Hz. A design goal of the CMDS is to reduce the system volume, weight and power by a factor of two with respect to DT-704/ASQ-233 system parameters. The CMDS is intended for use on UAVs (vertical take-off and fixed wing) employed for shallow water ASW and land-based target detection such as buried weapons caches and IEDs. An approach to reduce system size and weight is the use of Optically-driven Spin Precession (OSP) instead of conventional Magnetically-driven Spin Precession (MSP) to induce and observe magnetic resonance in the helium cell. OSP technology is attractive for a compact system because it eliminates the need for resonance drive coils and reduces the number of cells required for omni-directional operation. An OSP single-cell digital locked-oscillator scalar magnetometer was demonstrated for the first time under a recent NASA Phase I Project. The Phase I effort will include developing the CMDS specifications that will achieve the size, weight, power and performance requirements, and evaluating the applicability of CMDS to small UAV/VTUAVs and manned ASW platforms. The Phase II effort will involve fabrication of a CMDS laboratory breadboard based on the Phase I design.

Title:Antenna to Antenna Coupling and Electromagnetic Interference (EMI) Tool for Air Platforms.
Abstract:One of the most important problems encountered in an electromagnetic environment is that of providing compatibility between radiating and receiving RF equipment within the environment. This problem is a type of EMI and the goal of RF system designers and analysts is to achieve EMC where no interference problems exist between the various RF systems. The cost of providing numerous modifications to operational systems and the losses in efficiency resulting from the presence of interference represents a serious problem to numerous military and commercial organizations. Our team proposes to develop a software tool named Electromagnetic Interference Toolkit (EMIT) for predicting interference between radiating and receiving RF systems. The tool will consist of a graphical user interface (GUI) and underlying computational engines. The GUI (iEMIT) will pass user specified inputs to the computational engine (EMIT), will provide visualization of data, and will interface with a full wave solver for the generation of coupling data. During the Phase I, we will develop the architecture and implementation plan for the EMIT software, develop proof of concept modules for the computational engines, and validate those modules. The Phase II will focus on developing a GUI and implementing the proof-of-concept codes developed under the Phase I as robust engineering codes.

Title:Variable Color Ratio Window for IR Simulator Source
Abstract:Agiltron, Inc proposes a dynamic color ratio window of IR simulator source array for the open-air test and evaluation of missile warning and directional infrared counter measurements. The proposed device is innovative to utilize the variable IR absorption of window approach, achieving the desired performances by effectively changing the transmission coefficients in the interest IR wavebands, such as (3.8~4.1Ym) and (4.5~4.7Ym). This windows functionalities will enrich the major performances of the current open-air test IR source systems. The proposed IR window device is in standalone, enabling the operation flexibly with the present and under developing open-air test IR sources. This device offers intrinsic advantages of color ratio change in speed, large dynamic range, capability of operation in the outdoor severe environment, and great potential of profiling multiple spectrum bands. In the Phase I program, we will demonstrate a functional prototype of dynamic IR absorption type attenuation window with fast response and continuous ratio change. This experimental result will define our innovative system design concept, leading to a fully functional system in Phase II.

Title:Dynamic Color Ratio Infrared Simulator Source
Abstract:Typical threat missile signatures have a definitive characteristic color ratio signature. Infrared (IR) missile warning systems currently under development use two-color processing to discriminate missile threat signatures from non-threat signatures. It is necessary to have a dynamic color ratio capability to more realistically simulate various threat missile signatures. K Lab Corporation proposes to develop a robust IR simulator source that provides continuum spectrum between 2-5 micrometer, with controllable power intensities over the entire MIR radiant band, over one narrow pre-selected wavelength band, as well as the dynamic color ratio between two selectable wavelength bands. This IR source can be easily scaled up and integrated into an open-air surface-to-air missile simulator system.

Title:Two Color Dynamic Scene Generator
Abstract:OPTRA proposes the development of a fieldable two-color infrared (IR) source simulator based on fused projected images of two digital micromirror devices (DMDs), one for each IR spectral band. Our approach employs a broadband thermal IR source with a series of spectral filters to flood the DMDs with characteristic "red spike" and "blue spike" IR energy, respectively. The relative intensities of the two spectral bands are controlled through the duty cycle of the "on" image reflected by each DMD. We fuse the two simulated images and project the composite with a telescope of aperture diameter chosen to meet the radiant intensity requirements of this application. The overall approach offers a realistic IR source image of characteristic spectral, temporal, and radiant intensity properties of an actual missile plume.

Title:Dynamic Color Ratio Infrared Simulator Source
Abstract:The Naval Air Warfare Center (NAWC), Weapons Division, China Lake, has a requirement to develop a Dynamic Color Ratio Infrared Simulator (DCR-IRS) source for open-air test and evaluation (T&E) of missile warning and countermeasures systems. "Two-color" IR sensors employed by missile warning systems are used to discriminate against false threats by examining the "color ratio" of the signature, more specifically, the relative power in two mid-IR bands. Since the spectral (mid-IR) signatures of missile plumes can change significantly during the missile flight, an IR simulation with a dynamic color ratio capability is required for realistic T&E of these two-color missile warning systems. Technology Service Corporation (TSC) is proposing three innovative solutions to the DCR-IRS requirement. The primary solution, based on technology employed in the Infrared Simulator and Target Array (ISTAR) system at NAWC, uses flame sources configured to dynamically control the power levels in two mid-IR bands. Additional solutions use lasers and lamps to generate the required spectral signature. Under Phase I, TSC will investigate these solutions and others, performing tradeoff studies to establish feasibility; then, in Phase II, TSC will develop and demonstrate a proof-of-concept system that will provide ISTAR with an initial DCR-IRS capability.

Title:Sonobuoy System and Concept of Operations for Time-Reversal-Based Target Detection
Abstract:Existing multistatic airborne ASW systems require high power sources and are unable exploit the significant forward scattering target strengths due to the blinding presence of the direct blast. Time reversal (TR) is a recent method for focusing acoustic energy at a point using a pair of vertical line transducer arrays and offers the opportunity to exploit forward scattering from submarines. TR focusing can provide a measure of propagation channel stability, which provides a means for determining when the medium is disrupted as would occur when a scatterer such as a submarine passes between the two arrays. Moreover, because there is significant spatio-temporal focusing gain to be had with TR, there exists the opportunity to use lower power transmissions. Here we propose to determine the feasibility of a TR sonobuoy system for airborne ASW in the frequency band of a DICASS (AN/SSQ-62) sonobuoy and using vertical line arrays similar in dimension to a VLAD (AN/SSQ-77) sonobuoy. Operating at DICASS frequencies allows for achievable array apertures, exploits extremely high forward target strengths (> 50 dB) and improves the sensitivity of the TR. Post Phase I efforts would include implementing modifications to existing sonobuoy hardware for in-water demonstrations.

Title:Catapult Elongation Sensor
Abstract:Average catapult power cylinder temperature is currently inferred from elongation of the cylinder row, as measured by comparing the position of a pointer attached to the vented power cylinder relative to a graduated scale located on the flight deck. The Bow Safety Observer (BSO) must repeatedly take this reading from the flight deck during operations and then communicate the elongation to the Integrated Catapult Control Station (ICCS) or Central Charging Panel (CCP) to properly set catapult controls. Creare proposes to develop an automated system to measure the power cylinder elongation to reduce workload and safety risk for flight deck personnel and improve launch performance. This device will automatically provide a high-resolution, deck-temperature-corrected measurement to the ICCS/CCP and will maintain the existing pointer as a manual backup. During Phase I, we will evaluate several promising contact and non-contact measurement methods and design and fabricate prototypes of the most promising approaches. Phase I testing will help identify issues with possible approaches and synthesize solutions to address these issues. Phase I is intended to select the optimal approach, and Phase II will include the detailed development of a prototype that can be tested on a carrier.

Title:Inductive Catapult Elongation (ICE) smart sensor for Catapult Elongation Sensing
Abstract:The current technique for measurement of aircraft carrier catapult thermal elongation, while effective, is manpower intensive, slowly communicated, and potentially dangerous. Physical Sciences Inc. (PSI) proposes a powerful new enabling technology for sensing linear displacement of the catapult end automatically using a non-contacting, inductive technique. This technique uses the physical phenomenon of mutual inductance between an engineered conductive target and a planar array of conductors, both encapsulated in steel housings to form a sensor module. The sensor module outputs an electrical reading of displacement to a remote readout and display circuitry. To achieve this, PSI is teaming with OEM sensor provider Zettlex Limited, a world leader in monolithic, encapsulated, non-contact position sensing. The proposed measurement technique requires no moving parts, including bearings or couplings, no precise mounting, and no hands-on calibration. The result is an ideal linear displacement measurement for extreme shock and temperature environments where mechanical tolerances are difficult to maintain.

Title:A Passive, Rugged, Fiber Optic Catapult Elongation Sensor
Abstract:Visidyne proposes a novel fiber optic sensor to measure the elongation of steam catapults used by the Navy for launching aircraft. The sensor, originally developed by Visidyne for use in environments found in and around jet aircraft engines, is completely passive at the measurement point and so can operate in very harsh, high temperature environments. There are no electronics at the measurement head to limit high temperature operation. The stimulus and signal readout are coupled to the measurement head via optical fibers which can be tens of meters or longer, allowing remote operation with complete immunity to electromagnetic interference (EMI). Repeatability and absolute accuracy on the order of a hundred micrometers and resolution of better than ten micrometers is achievable.

Title:Reactive Missile Plume Simulator for Open-Air Testing
Abstract:The Naval Air Warfare Center (NAWC), Weapons Division, China Lake, has a requirement to develop a Reactive Missile Plume Simulator (RMPS) for open-air test and evaluation (T&E) of infrared (IR) missile warning and countermeasures systems. Adequate evaluation of Directional Infrared Countermeasures (DIRCM) requires that missile plume signatures be simulated for both jammed and non-jammed missile conditions. The high DIRCM IR tracker resolution dictates a continuous spatial plume simulation. Technology Service Corporation (TSC) is proposing two innovative solutions to the RMPS requirement. The primary solution, based on technology employed in the Infrared Simulator and Target Array (ISTAR) system at NAWC, uses extended infrared sources configured end to end to define jammed missile trajectories. The sources (10 meters in length) are instrumented with detectors for IR bands I, II, and IV to monitor DIRCM. A secondary solution, with potential for high simulation fidelity and flexibility, uses a remotely-controlled Organic Air Vehicle with a compact IR source and IR band I, II, and IV detectors. Under Phase I, TSC will investigate these solutions and others, performing tradeoff studies to establish feasibility; then, in Phase II, TSC will develop and demonstrate a proof-of-concept system that will provide ISTAR with an initial RMPS capability.

Title:Recognition of High-Range-Resolution (HRR) Profile Signatures of Moving Ground Targets for Combat Identification (CID)
Abstract:Limited success of current High Range Resolution (HRR) Aided Target Recognition (AiTR) approaches are largely due to the following shortcomings: 1) the heavy reliance on HRR profile features that are susceptible to measured HRR profile variability and 2) the attempt to declare targets at the highest level of specificity (e.g. T-72 instead of Tank) in all cases. The first shortcoming limits HRR AiTR performance because measured HRR profiles are susceptible to measurement noise, translational range migration (TRM), rotational range migration (RRM), speckle reflection, and self-occlusion. As a result, current approaches that use such HRR features cannot confidently discriminate between many target types. The second shortcoming aggravates the first by attempting to make highly specific target recognition declarations among ambiguous target types that typically exhibit only subtle differences in HRR profile features. In the proposed solution, Temporal Feature Correlation with Hierarchical Reasoning (TFC-HR), these shortcomings are overcome by employing: 1) HRR profile features that are robust to real-world sources of HRR profile variability and 2) hierarchical feature clustering that allows for target recognition at varying levels of specificity.

Abstract:Recent conflicts and world events have highlighted the need for one-hundred percent positive identification of intended targets before the launch of human or machine guided weapons. Recent advancements in numerous technology areas have empowered the consideration of placing aided target recognition (AiTR) capabilities on tactical airborne platforms.

Our innovative concept, tightly integrates the synthetic template database, AiTR algorithms and signal processing with the High-Range Resolution (HRR) mode of the radar sensor. Our approach included the development and integration of algorithms to provide extreme confidence detection and identification capability for time critical moving ground targets.

Title:Recognition of High-Range-Resolution (HRR) Profile Signatures of Moving Ground Targets for Combat Identification (CID)
Abstract:The objective of this proposal is to demonstrate the advantages of using a Hierarchical Hidden Markov Model for Aided Target Recognition of High Range Resolution (HRR) radar. A Hidden Markov Model (HMM) based technique has been previously shown to provide aided recognition of HRR with high probability of correct identification and low probability of error. This proposal extends current HMM techniques by utilizing a generalized HMM, known as the Hierarchical Hidden Markov Model, with several attractive properties not found in classic HMMs - in particular superior ability to learn the different stochastic levels and length scales present in the structure of the target features. One key difficulty in the application of any HMM is parameter estimation. The unknown parameters are typically point-estimated in a Maximum A Posterior (MAP) or Maximum Likelihood (ML) sense using an Expectation Maximization algorithm. We propose to utilize a Variational Bayes (VB) algorithm that does not generate a point estimate for the parameters but an approximation to the full posterior of the model parameters. The VB technique has shown in many applications to be less sensitive to overfitting and better-suited for active learning; the VB solution also allows one to perform model selection, here concerning the appropriate number of HMM states.

Title:Variable Remapping of Airborne Imagery
Abstract:We propose to design and implement algorithms for the remapping of scenes from one or more existing views. The routines to be developed will present realistic virtual views from any desired direction. Realism of the views increases with additional information about the cameras, scene and with the number of views. We show that realistic reprojections do not require multiple source views if given information about the camera that is typically available with imagery obtained from an airborne platform. Methods for presenting the optimal remapping given any level of information are presented. The methods working from the least information are also the fastest, and real-time processing of high resolution video data streams can easily be accomplished with small, lightweight systems.

Title:Variable Remapping of Airborne Imagery
Abstract:Recent enabling technologies are allowing Navy F18 strike aircraft and UAVs to work together fist-in-glove for close-quarters urban combat. Our proposal for TV2 (Targeting Video from VIVID) ties together these assets ever more effectively. TV2 remaps UAV target imagery into targeting imagery as will be seen from the F18's targeting pod. This speeds F18 visual cueing and target confirmation. Aerodyne's innovative approach side-steps need for online signature code computations, enabling TV2 real-time execution on COTS hardware, yet producing high-fidelity imagery. Two key modules comprise TV2. (1) View extrapolation, involving inference of target geometry, represents view-dependent illumination and shadowing effects not possible from image-warping or conventional IBR. (2) Atmospheric correction employs pre-computed physics, correcting color balance and saturation loss without needing non-portable hardware acceleration. Our Phase 1 effort will confirm the TV2 and transit case processor (TCP) ConOps with NAVAIR. Employing focused algorithm prototyping and testing, we will determine the best candidate view extrapolation algorithm and validate our pre-computed atmospheric correction scheme, all using efficient tools and methodologies in-hand. In Phase 2 we will fully implement and integrate TV2 with the VIVID algorithms on the TCP. The delivered TCP will be ready for Phase 3 T&E demonstration and subsequent operational transition.

Title:Variable Remapping of Airborne Imagery
Abstract:UAV to target-platform handoff requires the capability to remap imagery to conditions of the target platform to enable accurate identification (ID). SET proposes to design, demonstrate feasibility, and implement an operational system to provide variable remapping of airborne imagery. We propose to evaluate novel view synthesis solutions for instances where targets lie predominantly on a dominant plane as well as those for which non-planar characteristics are extractable. Rapid methods for both cases using computed homographies, properties of the image acquisition scenario, and platform metadata will be analyzed for effectiveness in terms of view synthesis and real-time implementation. We will analyze performance with respect to system parameters including range and perspective uncertainty, reliability of the synthesized view, latency effects and the overall enhancement of confirmatory ID (CID) due to the view synthesis. The system design incorporates correction for auxiliary conditions, including atmospheric and sensor characteristics, to provide target imagery that accurately depicts the expected view from the targeting platform. Feasibility of the proposed approach will be demonstrated in Phase I, with Phase II focusing on the development of a fully evaluated prototype integrated within the Video Verification of Identity (VIVID) platform.

Title:Whale Search Radar
Abstract:Marine mammals are often found in areas where US Navy ASW test operations are carried out. Several events have raised levels of concern that sonar emission could be causing deleterious impacts on marine mammals. For instance, in March of 2000, a mass stranding of beaked whales [NOAA report Dec 20, 2001] occurred coincident with an exercise of U.S. Navy ships operating mid-frequency sonar around the Bahamas. Other similar events have occurred. The solicitation objective is to detect, classify, and localize whales and other contacts in an ASW test range in a variety of sea-states. This will be accomplished by the Adaptive Methods and SSR Engineering team with a combination of commercial low-cost radar and other sensors, tracking and classification software, and operator controls and display. A system engineering and R&D development approach is given, with recommendations for work to be performance in Phase I through Phase III. A test data collection system and approach is described that uses available assets. Key R&D algorithms required are identified and developed.

Title:Low Cost Whale Detection and Monitoring with Radar/Optics
Abstract:Current ASW testing is often limited by the presence of marine mammals on ASW test ranges. The solicitation suggests the development of a radar system and associated algorithms to detect breaching whales in various sea states. The detection would then be handed off to an EO system for verification, classification, etc. The RADAR system must be able to discriminate the marine mammal blow or breach from open ocean breaking waves. The EO system, once queued must be able to reacquire the animal for verification and classification. This proposal suggests using an EO system that would not only be used as a verification/classification system but would also be used to detect non breaching submerged marine mammals in all sea states as well as breaching animals in high sea states. This EO system is combined with a modified COTS radar system which uses a single transmitter and two receivers. We suggest exploiting the phase difference between the two receivers to discriminate blows from open ocean breaking waves.

Title:Whale Search Radar
Abstract:Society's environmental concern of possible harm to marine mammals from a number of man-made factors, including man-made sound sources in the sea, has culminated in the Marine Mammal Protection Act (MMPA). As a consequence the US Navy faces the challenge of continuance of open ocean anti-submarine warfare training, which generates substantial artificial sound from various Sonar systems, while maintaining compliance with the MMPA. This program facilitates detection and tracking of whales over very wide areas at low cost by developing a Whale Search Radar. The system provides whale presence indications over very large areas quickly and inexpensively using methods that do not disturb the whales, thus providing marine mammal protection and facilitating "at sea" training.

Abstract:Renaissance Sciences Corporation and the University of North Carolina at Chapel Hill propose to develop new "intelligent" projector units (IPUs) that cooperate to create a single seamless wide-area (panoramic) image as part of a deployable visual training system for multiple viewers. The IPUs outwardly look like conventional digital projectors, but when casually arranged together in a set that projects in a common direction, will automatically learn their respective geometric and photometric relationships, and then continually and automatically estimate and correct geometric and photometric errors to maintain a single, seamless, high-fidelity image for multiple distinct viewers. Currently available projector technologies do not offer user-friendly, multi-tiled displays that self-calibrate and compensate for errors resulting from using multiple projectors. Instead, detailed and expensive manual labor is needed to achieve such display arrangements, which is not only inefficient, but also cost-prohibitive when needed in deployable and changing settings.

Title:Deployable Intelligent Projection Systems for Training
Abstract:Within a matrix of cooperating projectors a hybrid solution, containing both active and passive calibration elements, is essential for achieving automatic and continuous geometric rectification and color uniformity. We propose a method whereby projected structured light is utilized off-line to rapidly calibrate both the geometry and the color uniformity. Calibration camera(s) monitoring the projection surface provide visual feedback and allow a closed loop solution. The video feed of the projector provides a reference against which images, captured by the calibration camera(s), are compared to provide information for passive, on-line geometry and color drift assessment and correction. Detection of significant geometry or color errors - either during setup or normal operation - will trigger an active, off-line calibration procedure.

Title:A Hand-Held, Non-Contact Wire Stripper
Abstract:Mechanical wire stripping is completed on a daily basis throughout the military to support modifications or repairs to electrical equipment. In some cases, the ends of conductors need to be stripped, but the most challenging wire stripping occurs when a section of wire must be stripped that is within a wiring harness in a flight-line application. Unfortunately, there are several problems with the current mechanical wire stripping approach, including significant tooling needed to support the large number and types of conductors, the use of improper or unapproved tools, and poor control of the process. These problems are manifested in damaged conductors, incomplete insulation removal, and a considerable increase in man-hours for modifications. Creare's innovation is a novel Non-Contact Stripper (NCS) that is comprised of a compact head, which completes the wire stripping, and a backpack, which contains the support equipment. Our NCS combines the benefits of non-contact wire stripping with the convenience of a hand-held device. During the Phase I project, we will demonstrate the feasibility of our approach by fabricating and testing a proof-of-concept NCS at Creare. During Phase II, we will design, fabricate, and test a full NCS prototype.

Title:Alternative/Replacement Wire Stripper
Abstract:This program will provide solutions in response to the NAVAIR/DOD request for improved wire strippers (used for most aircraft/shipboard electronic and electrical applications) by the development of a database of information, and by the development/testing of new wire stripping concepts and technology. The database of information will help in the development of a national specification for wire strippers and components (leading to a QPL or similar approval process). The study and modeling of new wire stripper concepts will lead to improved performance and sourcing on this critical tool to the performance of aircraft/shipboard wiring systems. The Phase 1 research will focus on the applications and conditions that cause performance compromises with Aircraft/Shipboard wiring, and to examine and present 4 concepts that have not been offered by the tool/hardware industry.

Title:Multifunctional Portable Laser Wire Stripper
Abstract:To address the Navy need for a handheld, portable, rechargeable-battery-operated wire stripper for all wire insulation constructions, insulation types, cable types, and wire gauges in the Navy fleet, Physical Optics Corporation (POC) proposes to develop a new Multifunctional Portable Laser Wire Stripper (MPLaWS). This device is based on a laser, optics, and optomechanics for stripping. Innovative light control enables the MPLaWS to automatically strip wire of all sizes and types without damaging the conductors, selectively removing insulating material from any location along the wire or ribbon cable with great precision, or to create a specific stripping pattern on any ribbon cable. Fumes from the stripping process are filtered and absorbed by a fan-driven sorbent. MPLAWS can operate continuously for approximately 70 min. at 10 W output when used with a 20,000 mAh rechargeable battery. It is free of sophisticated, fragile, and heavy mechanical/kinematic stages, is similar in size to a three D-cell Maglite, and weighs ~2 kg. In Phase I POC will demonstrate the feasibility of MPLaWS to Navy personnel. In Phase II we plan to field a prototype handheld universal, multifunctional wire stripping system. This technology will significantly reduce aircraft downtime for maintenance, and increase aircraft safety.

Title:Omni-Directional Capability for Expanded SHARP Field-of-View
Abstract:The Shared Reconnaissance Pod (SHARP) provides the U.S. Navy with the latest digital tactical reconnaissance capability. NAVAIR wishes to make SHARP data available to a larger number of surface terminals, thus expanding the SHARP Close Air Support mission capability. Coupled with concurrent enhancements to incorporate net-centric capabilities on the SHARP, the addition of an omni-directional capability will further enable warfighter access to the SHARP data product and expand the pod's utility. To this end, Barron Associates, Inc., in conjunction with L-3 Communications, Communication Systems-West (L-3 CS-W) and Raytheon, propose to develop an omni-directional capability for the SHARP, which will enhance the reconnaissance pod with improved rear hemispheric coverage, provide a smaller minimal data link standoff, aid in the acquisition process, and improve data transmission time to the greatest number of surface terminals, thereby providing capabilities for a robust net-centric FORCENet implementation. The Barron team possesses an unrivaled level of expertise with both antenna design and development and the SHARP technology and is intimately acquainted with the implementation details related to the relevant trades; the research team will leverage their experience to design and develop the best omni-directional solution to enhance current and future mission capabilities for the SHARP program.

Title:Omni-Directional Capability for Shared Reconnaissance Pod (SHARP) Data Link
Abstract:The current Shared Reconnaissance Pod (SHARP) provides the capability to pass data to vessels at sea, but does not possess the capability to pass real time tactical imagery and data directly to air and ground operators. Passing real time data directly to ground operators increases the ground commander's battle space awareness and command and control of forces. It also facilitates close air support (CAS) to enable friendly forces to accomplish the tactical mission with minimal US casualties. Directional antennas have been the focus of data links in the recent past. This provided Commanders at the operational level good situational awareness of the battlefield, which enabled their planners to design branches and sequels to current plans. Advances in technology can now enable the ground tactical commander to have this same situational awareness and use it to execute a ground operation. An Omni Antenna can provide this capability to the existing SHARP with minimal changes in the pod. The omni antenna will enable data exchange to continue and will improve data transmission to the greatest number of weapon platforms, both in the air and on the ground. This antenna will also enable the greatest field of view for real time sensor to shooter data transfer.

Title:Omni-Directional Capability for Shared Reconnaissance Pod (SHARP) Data Link
Abstract:The Navy wants to add multi-band omni-directional transmission capability to the SHARP data link to enhance transfer to ship/shore/ground sites in tactical environments, including during various aircraft maneuvers and flight profiles. ThinKom is proposing to investigate and demonstrate our ultra-wideband (>10:1), low profile (0.5" thick), and shape-conformal WAVETRAP antenna technology as an omni-directional candidate for the SHARP data link pod. ThinKom, under Air Force Topic # AF03-101, is demonstrating WAVETRAP capabilities by addressing the need for airborne JTRS antennas. ThinKom proposes to start N07-022 with the initial AF03-101 WAVETRAP design (200 MHz to 2 GHz, instantaneously), and scale this existing antenna design to operate at 1.5 GHz to 15.5 GHz, while simultaneously "bending" the antenna to conform to the SHARP pod body. WAVETRAP antenna technology does not rely on a ground plane for operation, and shows especially good gain performance toward the horizon and over a hemisphere, making it an excellent airborne antenna candidate.

Title:Advanced Antenna Pattern and Mutual Coupling Prediction Software
Abstract:Numerical methods have proved very successful in low and mid frequency (VHF/UHF) regimes. However, these full wave methods are not efficient in handling electrically large problems dealing with radiation and coupling predictions for antennas on aircraft at higher frequencies (S/X/Ku/Ka bands).On the other hand, asymptotic/high frequency (HF) methods, such as the physical optics (PO) method and its modifications based on the physical theory of diffraction (PTD), do not scale with frequency. At these high frequencies, the uniform geometrical theory of diffraction (UTD) is more efficient and provides a physical ray intepretation for antenna radiation mechanisms and antenna interactions on large aircraft platform. However, simulations of large platforms using UTD has so far been accomplished using airframe models relying on canonical objects, thus, limiting use of UTD codes in handling curved structures such as a fighter aircraft. Applied EM along with its team members is proposing an advanced toolset based on UTD to handle CAD geometries that are body-conforming. This toolset will be also allow for interface with high fidelity antenna modeling tools. The proposed software will be capable of fully or partially coated (with material) realistic aircraft platforms using available diffraction methods. Radiation pattern predictions and coupling among antennas on the airframe will be handled efficiently using ray techniques within the context of UTD. A friendly graphical user interface with pre- and post-processing capabilities will be an integral part of the toolset, and will allow for CAD importing and visualization of realistic aircraft models as well as display of the physics and output datasets.

Abstract:A software system for predicting the performance of antennas mounted on electrically large platforms of arbitrary geometry and with material coatings is proposed.

The system will run on personal computers and will perform the required computations in real or near-real time. The system is intended for use by engineers and will have a graphical user-friendly interface. The proposing team previously developed similar systems for perfectly electrically conducting (PEC) platforms.

Title:RF Sensor Performance in Electrically Large, Complex Environments
Abstract:Modern military and commercial aircraft include numerous RF systems and associated antennas serving a multitude of functions. Typically, the designed free space performance of antennas is degraded by their installation on the airframe. Also, the presence of many RF systems in a small region creates enormous opportunity for undesired inter-system electromagnetic interference (EMI) via antenna-to-antenna coupling. These facts present the antenna/platform integrator with an enormous problem: how to place the numerous antennas on the airframe so that they can perform their stand-alone functions while minimizing interference. We propose to develop a tool that implements asymptotic ray tracing on electrically-large, high-fidelity airframe CAD models to accurately predict installed antenna performances and co-site interference. Phase I will focus on proof-of-concept development and validation core and advanced methods. In Phase II, the computational engine will be coupled with a sophisticated graphical user interface (GUI), with emphasis on visualization to aid the user in problem setup, multi-system management, and interpretation of results. The tool will offer advantages over existing asymptotic solvers through more accurate near field interactions, creeping wave algorithms for realistic geometries, and powerful diagnostic features.

Title:RF Sensor Performance in Electrically Large, Complex Environments
Abstract:The radiation from antennas mounted on a geometrically complex platform, such as an aircraft, remains a challenging electromagnetics problem. Since military applications often require multiple antennas on the same platform, the analysis of interference is also important. It is difficult to use full wave electromagnetic solutions for such problems at high frequencies due to computer memory and computation time required. The best alternative is to use full wave methods only to analyze the antenna radiation characteristics, and to use the Geometrical Theory of Diffraction (GTD) to predict how energy propagates over the electrically large platform. A key advantage of GTD over other high frequency asymptotic methods is the accuracy with which it can model propagation along curved surfaces by means of surface diffracted rays, or creeping waves. The GTD also has the ability to combine creeping waves with diffractions and reflections from other features, such as the wings and stabilizers on aircraft. Another important is the memory and computation time does not increase with frequency, since the time to find the ray paths depends only on the complexity of the geometry not on the electrical size.

Title:Interactive Marine Mammal Communications
Abstract:A team comprised of Analysis, Design and Diagnostics, Inc. (AD&D), Woods Hole Oceanographic Institution (WHOI) and Advanced Acoustic Concepts, Inc. (AAC) will provide the air community an effective Marine Mammal Mitigation Program. This team has developed an automated marine mammal detection and classification system which automatically detects and classifies marine mammal vocalizations. Under this effort this system will be modified to support airborne sensors for automated detection and classification of marine mammals. Once the mammal has been classified, an appropriate acoustic stimulus will be generated by the fine parameter estimation (FPE) module to alert the animals to leave an area prior to active operations. The credibility of this approach will be investigated by a scientific review to be conducted by Woods Hole Oceanographic Institution. An alternative solution to be investigated under this SBIR effort will involve modifying our current system to automatically detect, classify and localize marine mammal vocalizations using airborne sensors. Once the marine mammals have been localized, a new ping plan will automatically be generated in a real time environment by the software developed under this effort. This software will use current Navy policy to ensure that the active sensors used are outside the hazard zone of the detected marine mammals while maintaining a high probability of detection (Pd) during active training exercises.

Title:Interactive Marine Mammal Communications
Abstract:A series of whale strandings have been correlated to the operation of naval medium-frequency active sonars. Sonalysts and WhaleAcoustics will define how to clear an area of cetaceans using non-injurious sound prior to the start of naval exercises. We propose to analyze existing data gathered at the Southern California Offshore Range (SCOR). These continuous broadband recordings include the pings of active sonars and communicative calls produced by identifiable species of cetaceans. Anecdotal evidence suggests that after a few days of Navy exercises, the SCOR region is empty of calling cetaceans. Our analysis will determine how and why this happens, identify the sounds which may be causing the animal's departure, and include ship noise and sonar transmissions. Correlating the occurrence of these sounds with possible changes in the animal's acoustic communication calls and travel directions will provide insights on how to clear an exercise area of cetaceans. The result of these analyses alone could impact future Environmental Impact Statements filed by the Navy with the National Marine Fisheries Service for sonar test ranges and could be brought into court in the continuing legal challenges to the use of Navy sonar under the Marine Mammal Protection Act.

Title:Next Generation Aircraft Wiring Insulation
Abstract:Currently used wire harness technology consisting of Teflon-Kapton-Teflon (TKT) composite tape has some significant performance issues. Kapton-H has been replaced with Teflon -T (Dupont trade name OASIS) which has reduced but not eliminated the hydrolysis problem. Engineers at one of the primes for the V-22 have told us that the one issue with kapton composite is it unravels and once kapton is exposed it is susceptible to hydrolysis. Tape construction suffers abrasion when it is pulled through conduits or been installed since the tape edges tend to catch on even small protrusions. A significant worry for engineers at primes is the cost of TKT composite tape and the fact that it has a single supplier - Dupont. most of these problems can be solved with extruded insulation, but extruded insulations in the past have not met temperature requirements. Linden Photonics proposes the use of a new class of high temperature, high strength materials for use as extruded wire harness insulation, with the following properties: no thermal degradation up to 450 deg.C; excellent chemical stability; no hydrolysis problems even at elevated temperatures; no known arc tracking problems; extrudes well therefore low cost; laser markability; Linden's past experience with these material reduces risk for the proposed Phase 1 effort. Our Phase 1 and 11 sub-contract partner is a V-22 prime which will expedite potential technology insertion.

Title:Next Generation Aircraft Wiring Insulation
Abstract:Wiring repairs represent a large cost segment to the US Navy. According to the Navy, wiring problems cause 1,400 aborted missions per year, 2.5 electrical fires per month, and require 1-2 million operational man-hours per year for trouble shooting/repair. Currently used wire insulation is susceptible to degradation at high service temperatures. Luna's team has developed a novel class of polymers that combine high mechanical strength and thermal stability for this application. These materials will prolong the life span of the wire insulation and thus reduce the number of out-of-service hours due to repair of failed wire insulation. In addition, due to the improved thermal and mechanical properties, this new polymer can be applied as a single sheath coating, thus reducing the weight and cost of the insulation.

Abstract:This SBIR proposes to investigate various chemical solutions and approaches for improving the chemical and hydrolytic stabilities of polyimide polymers without affecting the insulating properties of the polymer substrate. Through polyimide modification with siloxanes, fluoropolymers and other treatments, permanently water repellent polyimide materials will be produced. Other commercial polymers with superior insulating properties and chemical stabilities will be identified and evaluated as neat polymers and polyimide blends. Electrochemical impedance spectroscopy and other electrical property measurements will be used to monitor the hydrolytic and chemical degradation resistances of the modified polyimides and commercial polymers during long-term exposure to aqueous alkali solutions and other chemicals. Based on the mechanical and chemical degradation tests and other electrical property testing, three polymer candidates will be selected for further study and optimization. The team will then develop film formation methods for each selected polymer candidate to determine the polymer candidate most suitable for development into a low-cost, high-volume electrical wiring production process. The team's experience in aircraft electrical wiring systems and demonstrated expertise in synthesizing new polymer materials, as well as experiences in transitioning technologies, presents aerospace communities with the opportunity to obtain durable and environmentally compliant next generation wiring insulation materials.

Abstract:Eliminating manual activities for aircraft tie-down will have significant benefit in reducing carrier manning. A robotic approach would not be practical as manning replaced by robots may be offset by added robot maintenance crew, not to mention that mobile robots may jam the deck space and deck mount robots may impose significant Ship-Alts. INNOVATEX INC proposes an Aircraft Anchoring Device (AAD). The aircraft drops down some suction cups to grab the deck surface just like a ship dropping anchors to grab the ocean floor. Although this approach involves some modifications on the aircraft but the benefit is huge. Phase I effort focuses on demonstrating the concept and developing the control mechanism. Our initial calculation indicated that a 21 inch diameter AAD can hold against 10,000 lbs of pulling force. Depending on the wind over deck, about 6-18 AADs are required to hold down a 60,000 lb aircraft. The design challenge is to make the AAD light weight and foldable so that it can be easily carried by the aircraft. This approach involves no changes on the aircraft carriers.

Title:Innovative Approaches to the Fabrication of Composite Helicopter Tail Booms
Abstract:Current production methods of tail booms for rotary-wing aircraft are expensive, inefficient, and produce hazardous byproducts. Conventional methods for production of high end composite parts are both labor intensive and expensive. Alternate methods, such as curing parts in ovens to eliminate expensive autoclave operations, still do not eliminate the high cost of the tooling that needs to withstand the high temperature cures. The purpose of this project is to demonstrate the effectiveness of using 3-D weaving and innovative electron beam curing of polymer matrix composites for low-cost fabrication of low production rate, high-performance tail booms for Navy and Marine Corp rotary-wing aircraft. By using off-axis 3-D woven fabrics, the composites will have increased tolerance for torsional loads which are critical to helicopter tail booms. Furthermore, electron beam curing is less expensive, faster, safer, and produces higher performing parts then traditional curing techniques.

Abstract:Light weight, low cost structures is the direction that many aerospace companies are working toward. Our objective in this Phase I program is to demonstrate our low cost effective manufacturing methods with thermoplastic composites while maintaining structural integrity. A continuous graphite fiber reinforced thermoplastic prepreg tape will be used in conjunction with our automated in-situ fiber placement technology to demonstrate repeatable, accurate and low labor methods to produce high quality composite helicopter tail booms. Our use of continuous fiber reinforced prepreg tape allows us to tailor the lay-up to suit the design criteria at hand. Our technology offers the ability to integrate stiffening components into the skin structure without the use of conventional mechanical fasteners. Instead we will demonstrate the melt bonding attachment techniques that result in totally integrated structure without the use complicated, high cost tooling or fasteners. These techniques offer the ability to produce a finished part of almost any geometry in a single set-up step. There is not the need for labor intensive post processing that is inherent with many other composite manufacturing methods. This technology is both versatile and robust enough to produce a variety of different part configurations in a low cost fashion while still maintaining the high quality demanded by the aerospace world.

Title:Low Cost, Flexible Pultruded Design for Helicopter Tail Booms
Abstract:The Flexible Pultruded Design (FPD) for composite helicopter tail booms utilizes low cost adjustable tooling and the automated pultrusion process to provide very high quality and very low part unit cost. FPD is ideal for early fabrication of flightworthy structure during SDD and LRIP program phases. FPD is comprised of sandwich construction utilizing X-Cor core (comprised of a multitude of fine pins) that provides Z-direction thru-thickness reinforcement as well as shear strength and stiffness. FPD sandwich construction provides high structural efficiency (i.e. lightweight) and features a structural shape that allows four identical pultruded details to be trimmed and assembled to form a completed tail cone assembly, including taper if needed, where the width and height dimensions can be independently accomplished without affecting the pultrusion die. The panel features a molded (pultruded) panel joint that is tooled and designed for optimum joint quality and strength using a bonded/bolted construction. The Z-pins in the core provide enhanced ballistic tolerance, which offers considerable benefit in applications such as helicopter tail cones where small enclosed volume and nonredundant load paths often exhibit ballistic vulnerability. Phase I will generate full scale proof-of-concept Demonstration hardware.

The spectral RGB sensor will be standardized against the CEI color spectrum for inter-operability. The spectral sensor and backlight system will be developed to provide NVIS compatibility. The proposed effort will extrapolate from existing C3I work in RGB LED spectral color control and backlighting developments.

Title:Homogenized Hybrid Ultra-Bright Backlight
Abstract:To address the US Navy need for a high-performance direct-view LED-based AMLCD display, Luminit, LLC proposes to develop an innovative high-luminescence, high-contrast, high optically and electronically efficient airborne Homogenized Hybrid Ultra-Bright Backlight (2HUB2). This inexpensive and reliable device is based on mature backlight technology (which couples excellently with recent LED innovations, utilizes just a few (1-2) superior-quality films in the stack), a hybrid diffuser technology, low cost electronics and smart synchronization. The device will offer unparalleled performance in homogenization and brightness (more than 350 ft-Lambert), increase the efficiency by 40%, provide high contrast ratio and enhanced image clarity. The power consumption of the 2HUB2 system is estimated to be 8 W, achieved by employing ultra-thin, fully synchronized LED array-based innovative Phase I design. In Phase I Luminit will demonstrate the feasibility of 2HUB2 by laboratory proof-of-concept device of 6,e8 in. size consisting of LED sources, the backlight itself, and AMLCD display, and will perform the extensive testing of its components, power, synchronization, electronics, and display properties, including reliability. In Phase II Luminit plans to develop a full-size integrated version of 2HUB2 aimed for airborne applications with night-vision capabilities.

Title:Smart Display Backlighting
Abstract:This proposes research and development of "smart" backlighting for active matrix liquid crystal displays (AMLCDs) employed in combat aircraft. "Smart" backlighting means advanced technology that enhances performance and significantly improves mission effectiveness. Effectively controlled light emitting diodes (LEDs) synchronize backlighting illumination with display imagery, producing clear pictures with high contrast. The proposed device fits in back of LCDs, and consists of a front plane (the LED array), and a back place (the controlling electronics) integrated with the data stream illuminating the display. In the LED front plane, electricity is directly converted into visible light. In the back plane, the high switching speed of electronics tightly control front plane pixels. Other performance metrics are also measurably improved, including lower power requirements and heat produced, better than in currently available commercial products. The proposed device is environmentally rugged, tolerant of operational vibration, and resisting electromagnetic interference from cockpit instruments. The result is highly dependable performance. Product brightness can be manually adjusted so that it is night vision compatible. LED technology has a long history of use in many commonplace consumer products with high reliability, and the proven technology is poised to economically respond to the many performance challenges of this important application.

Title:Low-Cost, Eye Limiting Resolution, Immersive Display
Abstract:Advanced Simulation Displays (ASD) proposes to leverage the work already accomplished building seamless wide field of view displays utilizing commerical flat panel display technology. Three of these systems have been build and delivered utilizing fifty inch plasma panels combined to provide a seamless scene for UH-1H simulators. In addition, ASD is under contract to build three channel seamless plasma displays for the Navy's P3 TORT program. All of these systems that have been developed to date, implement technology developed and is currently patent pending, to tile flat panel displays in either the horizontal or vertical direction. This proposal takes the technology developed by ASD and extends it to allow seamless tiling in both the horizontal and vertical directions simultaneously. In addition, to extending the horizontal and vertical fields of view, at least one display channel will be augmented with a secondary flat panel which will be incorporated into the baseline design to provide 3D stereo imagery in a limted viewing area to support close in visual training tasks. The entire display can also be vertically pivoted to place the display in the optimum postion as required for each training task.

Title:Magnetic Noise Mitigation on an Agile UAV
Abstract:The next generation of ultra-small magnetic sensors will be deployed on small UAVs for a variety of military and commercial applications. The algorithms resulting from this SBIR will allow these new sensors to perform near their sensor noise level. While the U.S. Navy will accrue obvious benefits in submarine and buried littoral target detection, the Army will deploy mass swarms of small UAVs against IEDs and buried land mines. The intelligence community could benefit from an improved ability to detect underground facilities and buried weapons of mass destruction. The new noise mitigation system with the new sensors will help transition the environmental and geophysical survey industry to a wide array of small unmanned aircraft. Cheaper UAV alternatives to lengthy surveys with manned aircraft and large scalar sensors will become the norm. Benefits will include lowering costs for mineral exploration, environmental hazards detection, and construction costs, resulting in a larger and more profitable industry.

Title:Adaptive Cancellation of Magnetic Background Noise for Anti-Submarine Warfare
Abstract:To address the Navy's need for magnetic noise mitigation algorithms to improve the range and performance of magnetic anomaly detection sensors to support anti-submarine warware, Physical Optics Corporation (POC) proposes to develop a new Sensor Integrated Magnetic ELF/ULF Noise Mitigation (SIMENM) system based on a customized POC 3D geometric magnetic compensation (GMC) framework and a network of COTS ancillary sensors. The innovation in self-identification, isolation, and mitigation of correlated, non-linear, and non-Gaussian noise will enable the system to significantly reduce the platform and environmental noise level in the measurements of a highly sensitive scalar magnetometer and achieve the stated noise reduction goal: 40 (threshold)/10 (objective) pT/root Hz @ 0.05 Hz and 1 (threshold)/0.3 (objective) pT/root Hz from 1 to 10 Hz. The adaptive cancellation is achieved through a bidirectional state updating process, forward propagation of uncertainties, and backward propagation of constraint errors. In Phase I POC will demonstrate the feasibility of SIMENM by identifying, designing, and integrating key system components into a subscale demonstration prototype. In Phase II we plan to develop a full-scale sensor prototype that can be tested, evaluated, demonstrated, and adapted for insertion into ongoing acquisition programs, including Littoral Antisubmarine Warfare and Air Antisubmarine Warfare.

Title:Advanced Magnetic Signal Processing for Littoral Antisubmarine Warfare (ASW) Using an Inboard Magnetometer System
Abstract:This SBIR Phase I proposal describes the development of a conceptual design for Matched-field Gradiometer Processing (MGP) for ASW, an advanced processing approach capable of taking advantage of recent and pending advances in ultra high-sensitivity scalar laser magnetometer development for airborne and undersea ASW. This matched-field approach to magnetic gradiometer processing for magnetic anomaly detection in ASW systems will provide unprecedented precision in magnetic noise reduction, detection, target parameter extraction, localization, and prosecution/tracking. Under this SBIR project, the processing of magnetic sensor data will be defined to provide target information and identification never before accomplished in real-time operation. Advanced noise reduction methodology will be developed to improve and enhance detection and localization of sea and land targets. Under this Phase I Project, the feasibility of implementing this advanced algorithm for operational use in Phase II will be established.

Title:Innovative Rotorcraft Flight Control Systems Options to Enhance Shipboard Operations
Abstract:Rotorcraft shipboard operations have been an essential but demanding aspect of modern maritime activities. The shipboard rotorcraft are strongly affected by the unsteady ship airwake and the dynamic ship motion. Significant progress has been made in analyzing these effects on the shipboard operating rotorcraft. There is, however, a lack of research for applying these analytical modeling capabilities to the development of advanced flight control systems in order to benefit the rotorcraft shipboard launch and recovery operations by enhancing flight safety and reducing pilot workload. This proposal aims at developing a unified rotorcraft flight control design and evaluation environment to facilitate a systematic development of advanced rotorcraft flight control system algorithms. The proposed research will (1) develop innovative rotorcraft flight control system algorithms to account for the effects of the shipboard operating environment; (2) develop a shipboard rotorcraft simulation environment to facilitate accurate plant and disturbance model generation and control design evaluation in support of advanced flight control model development; (3) prototype a control toolkit that can be used with user customized modeling and simulation environment; and (4) integrate the control design toolkit into a comprehensive rotorcraft/ship simulation program to demonstrate the functionality and investigate the effects of the ship airwake and the ship motion on rotorcraft performance and dynamics.

Title:Innovative Rotorcraft Control for Shipboard Operations
Abstract:An adaptive flight control concept is proposed to better compensate for disturbances on the rotorcraft due to ship airwake effects and the moving ship deck during helicopter or tiltrotor shipboard operations. The flight controller could ultimately be used on a fully autonomous system or in a pilot-assist mode on manned rotorcraft. A parameter identification algorithm and an on-line learning approach will be applied to estimate in real-time important effects of the ship airwake and ship motion. The system would identify both the statistical properties of the apparently random characteristics of the airwake as well as the re-peatable and deterministic disturbances of the airwake due to the ship's geometry and motion. A flight controller will be designed that uses the information from the on-line learning algorithms to improve dis-turbance rejection properties of the aircraft. The system would provide enhanced feedback compensation to improve rejection of disturbances due to random airwake forces impinging on the vehicle, and feed-forward compensation to help compensate for deterministic airwake disturbances. A high-fidelity tilt-rotor UAV simulation will be further advanced and employed to demonstrate and evaluate the adaptive control system. Preliminary real-time piloted simulations will be the focus of the Phase I Option effort.

Title:Innovative Rotorcraft/Ship Environment Suppression for Enhanced DI Flight Control
Abstract:Rotorcraft flight operations in the shipboard environment, called the Dynamic Interface, is extremely challenging due to the motion of the ship deck and the surrounding turbulent ship airwake. Higher bandwidth flight controls can improve vehicle handling qualities for supporting both manned and unmanned operations of rotorcraft from ships, but these may only be implemented if due consideration is given for both rotor dynamic response and accurate ship motion measurement. The work proposed here will address these issues through an innovative blending of rotor motion estimation and feedback with augmented measurement of ship deck motion, providing sufficient control system lead for expanding the safe operational environment of rotorcraft in the DI environment. Considerable leverage will be made from CDI's past work in DI simulation, rotorcraft aerodynamic analysis, ship airwake prediction, flight control design, rotor motion sensor hardware development, and rotor state feedback control. Validation of the approach using both batch and manned flight simulation on PCs will be combined with a system integration study to address implementation issues for current and future rotorcraft in the Phase I program. Follow-on work will culminate in a complete hardware-in-the-loop manned flight simulation test program to provide system risk-reduction prior to Phase III flight testing.

Title:Innovative Rotorcraft Flight Control Systems Options to Enhance Shipboard Operations
Abstract:The primary objective of this SBIR Phase I effort is two fold: (1) offering a reliable and robust control law to further enhance the V-22 Flight Control Systems (FCS) beyond its current performance level via an augmented adaptive control scheme and (2) extending the restricted operational envelope (i.e., ship motion, ship airwake, wind-over-the-deck conditions, confined landing areas) of rotorcraft operating in the vicinity of ships. These two objectives are achieved through development of the advocated adaptive high performance robust FCS using two proven adaptive control schemes, namely -D and Simple Adaptive Control (SAC) architectures. These two design techniques are well recognized by the control community for their robust performance under parametric and functional uncertainties in the system dynamics. In addition, the proposed -D/SAC design concept also offers several important and attractive design features that are not offered by other modern design techniques. These features include: (1) ease of implementation without demanding high processing power, (2) easily implementable to work in concert with the existing V-22 Flight Software, (3) reliable adaptive performance capability through a direct adaptive control design paradigm without requiring an onboard aircraft parameter estimator.

Title:Innovative Material for Enhancing Landing Gear Life
Abstract:United States Navy (USN) aircraft landing gear components are currently made from high-strength high-toughness steels (AISI 4340, 300M, AerMet100) that lack corrosion resistance and require external means of corrosion protection, such as chromium or cadmium plating. The USN is in need of a low cost, corrosion-resistant metal alloy with mechanical properties similar to AerMet100. Under the proposed Phase I effort Malltech will utilize a mathematical model based on prior experimental and analytical work with steel alloys to design a new alloy and select appropriate thermal treatment resulting in the desired mechanical and corrosion resistance properties. Limited alloy production and testing will be done to assess feasibility and correlate with the computational model. A similar approach was successfully applied by Malltech in SBIR AF02-147 Phase I & II project to develop a conventionally produced low cost alloy with high strength and high toughness characteristics similar to the AerMet100.

Title:Computational Design of Advanced Alloys for USN Landing Gear
Abstract:The United States Navy (USN) uses a number of high strength steels, primarily AerMet100, in demanding landing gear structural applications. Unfortunately AerMet100 is expensive and, despite impressive mechanical properties, is subject to stress corrosion cracking (SCC) and requires toxic plating operations for corrosion resistance. QuesTek Innovations proposes to apply its proven Materials by Designr methodology to work with the USN to develop a low-cost, high-strength, high-fracture-tough, SCC resistant alloy. Extensive experience and a prior knowledge base in high-strength corrosion-resistant alloys uniquely positions QuesTek to use modeling and simulation technologies to develop this alloy for the USN. In QuesTek's prior work on landing gear steels with both the USN and USAF, several novel prototypes extending the current state of the art in optimizing strength, toughness, and corrosion resistance were designed and developed. QuesTek will extend this prior work to consider two design optima: a high-performance stainless steel, and an AerMet100 drop-in replacement alloy with significantly lower cost. This two-pronged approach reduces technical risk and maximizes the resulting benefits. While the target platform for this program is the Presidential Helicopter; QuesTek envisions performance, cost, and reliability benefits for landing gear systems throughout the USN and commercial aviation.

Title:Advanced Aircraft Simulator Flight Fidelity Evaluation Measures
Abstract:While new technology is making flight simulators more affordable, validating the simulators for training applications remains costly. This is mostly due to the inefficiency and inconsistency of the subjective validation approach currently used. Performing trial and error iterations based on the subjective opinion of multiple pilots is costly and inefficient. A major deficiency in the current validation approach is the inability to separately determine the validity of the simulator cueing systems. The subjective validation is end-to-end and the flight dynamics model, after initially being validated in isolation, is ultimately modified to compensate for cueing deficiencies in the total system. Advanced Rotorcraft Technology, Inc. (ART) has proposed a new validation criteria and methodology that provides a quantitative metric for the fidelity of the simulator cueing systems for each training task. The methodology also allows determination of the most cost effective configuration of simulator cueing systems that will satisfy the training requirement. If the cueing systems are inadequate for the training task, this methodology also provides quantitative guidelines for modifying the flight dynamics model to compensate for cueing deficiencies. In Phase I, the proposed methodology will be developed and tested on an in-house OH-58D simulator that ART has tested to FAA Level D standards.

Title:Creating Requirements for Operational Safety Support Through Assessment of Flight-simulation Fidelity (CROSSTAFF)
Abstract:Effective simulator-based training can dramatically increase safety margins when pilots are flying actual aircraft. However, the effectiveness of simulator-based training hinges on the fidelity with which simulators capture critical features of actual flight situations. Aptima proposes to develop measures of aviation simulator fidelity. Our approach involves identifying factors contributing to specific safety vulnerabilities, identifying the extent to which those factors can be replicated in current simulation platforms, identifying the data output capabilities of the simulator platform, and demonstrating how those data could be used to produce meaningful measures of simulation fidelity - that is, measures of the extent to which the simulation captures the critical features related to safety in actual flight. Our development of measures will be accelerated by the use of Aptima's existing suite of performance measurement techniques and tools, which have been applied to training and training simulations for the Navy, Marines, and Air Force.

Title:Fidelity Assessment Simulator Tool (FAST) for Advanced Aircraft Simulator Flight Fidelity Evaluation Measures
Abstract:Typically, flight simulators are designed with the intent of expanding pilot skill levels in, low risk, cost effective environments. Military pilots often encounter a very broad spectrum of mission requirements, composed of many subtasks; therefore flight simulator fidelity requirements will presumably vary with the complexity of skills required to complete a particular mission. The current problem is how to objectively (and consistently) match simulator fidelity with operational flight trainer acceptance while keeping factors such as cost, risk, visual scene image generation (IG), training mission requirements, simulator components (hardware and software), and training time, manageable, reliable, and realistic. When comparisons between mechanical parameters and software performance are conducted, it's not unusual that fidelity requirements are sometimes based upon how much technology an organization can afford, instead of assessing technology levels needed for optimal training environments. To alleviate the problem of matching fidelity with desired training outcomes, SDS proposes the development of a software based, Fidelity Assessment Simulator Tool (FAST) that provides valid, reliable, and accurate simulator fidelity comparisons of any type of aircraft. These objective comparisons will enable the Navy/Marine Corps to maximize training investments through simulator fidelity analysis, to gauge how well specific requirements are met during simulated training evolutions.

Abstract:VVVVVThe problem building build a ground based training device that accurately replicates the aircraft well enough to accomplish the training has been the challenge since before World War II. Advanced aircraft flight fidelity measures are needed to better quantify the criteria required to define if the training fidelity is good enough for Navy/Marine Corps operational flight trainer acceptance. VSAT will conduct research to define a set of simulator aircrew performance measures that are necessary to evaluate current aircrew performance and predict future performance. VSAT will also conduct research to define a set of fidelity measurements for various simulator subsystems. VSAT will establish the relationship between the two sets of measurements to show that the fidelity measurements provide can demonstrably support the aircrew performance measurements.

Title:Military Training Systems Acceptance Test & Evaluation
Abstract:The Navy's flight and maintenance training simulators systems are growing in complexity, and becoming more and more dependent on COTS HW and SW, as well as, the successful re-use of software developed from other programs. Despite the advances in development practices and tools, the goals of accelerating the rate at which training systems can be delivered, and accepted, while reducing their costs cannot be met without comparable improvement in the practices and tools for acceptance testing. Training system deficiencies that are not identified and corrected during testing have resulted in reduced performance and training effectiveness. An excellent opportunity exists to rapidly accelerate the ability to deliver advanced capabilities of training systems by significantly reducing the overall acceptance testing timeframe through the use of commercial testing automation tools, which are either existing or emerging, throughout the test and evaluation life cycle.

Abstract:The zone-plate-array-lithography (ZPAL) system being commercialized by Lumarray, Inc. (the ZP-150) is proposed as the ideal means of providing quick turn-around on masks for DoD integrated-circuit manufacturing, as well as for maskless direct patterning of wafers. We propose to deliver 10 photomasks, made on the ZP-150, to the University of Maryland and 3 photomasks to a DoD manufacturer. In addition, three wafers will be exposed on the ZP-150 for both Univ. Maryland and the DoD manufacturer. Maskless lithography is the most cost-effective solution for manufacturing IC's in low volume. ZPAL has delivered high-quality lithography, and promises pattern-placement accuracy and throughput that is superior to what is possible with electron-beam lithography. We show that by means of absorbance modulation, ZPAL technology can be extended to sub-20 nm resolution, and that anticipated improvements in the pixel count and addressing rate of spatial-light modulators will enable ZPAL throughput to approach that of optical-projection lithography.

Abstract:A pulsed fiber laser capable of very rapid amplitude modulation is proposed. Producing more than 5 W output at 532 nm, the system incorporates a very fast fiber-coupled electro-optic modulator, capable of reproducing waveforms up to the 10 GHz range. When used in a hybrid lidar-radar system, the laser will enable discrimination against multiply scattered photons, powerfully enabling imaging of targets even in very turbid water. Fiber laser technology enables the laser to be robust, alignment- and contamination-insensitive, and inherently ruggedizable. The laser (based upon recently commercialized designs) is very compact and power-efficient, enabling near-term deployment in Naval systems.

Title:Fiber based modulated pulsed source for microwave photonic lidar applications
Abstract:The proposed high power green laser source with RF-modulated pulses will enable a new class of remote sensing instruments capable of achieving precise information from environments dominated by backscatter signals. Current remote sensing technologies lack capability to identify and discriminate objects under real-time environmental conditions. A hybrid lidar-radar system consisting of a pulsed laser is modulated at RF frequencies is capable of extracting meaningful data from the high intensity backscattered light in the water. A 500 kHz pulsed, fiber-amplified laser is proposed for the laser source. The pulse envelope is modulated via an electro-optic switch from 500 MHz to >1 GHz. The average power is amplified to several watts using a multi-stage Yb-doped fiber amplifier. In order for effective transmission through water, the 1064 nm radiation is frequency converted to 532 nm using either periodically poled stoichiometric lithium tantalate (SLT) or potassium titanyl phosphate (KTP). The all fiber design using a Yb-doped fiber amplifier, an EO switch and PPSLT or PPKTP ensures highly efficient and rugged performance. In addition to enabling a major advance in remote sensing within the littoral zone, the hybrid source will find direct application in involving highly obscured environments such as dust, smoke or moisture-laden environments.

Title:Real Time Physics-Based Airflow Environments for Distributed Aircrew Training
Abstract:Rotorcraft operations are critical to current and future Navy missions, and thus the imperative to provide high fidelity, distributed training with enhanced realism for the aircrew and ship's company will inevitably intensify in coming years. The technology proposed here will enable the development of revolutionary simulation tools that capture the full range of flight operations and weather conditions experienced by crews on aviation-capable ships. This effort will build on real time, physics-based modeling tools to simulate the complete ship/helicopter operational environment, leveraging CDI-developed rotorwash and flow field models already in service in support of Navy simulation activities. A key feature of the project is that environmental effects, including ship airwake, will be directly simulated using physics-based models, in contrast to data-driven approaches that are inappropriate for general distributed training applications. The simulation will also incorporate innovative tools, now being developed to visualize rotor wakes and transport of airborne materials, to create a "visible wind" to assist trainees in interpreting the airflow environment. Other effects (e.g., ship motion and structural response due to airflow-induced loads) will be integrated for use within distributed simulation environment architectures, allowing the re-use and integration of existing models techniques and commercial software tools.

Title:3D Tool for Physics-Based Weather Simulation in a Training Environment
Abstract:High-end weather simulation tools currently available focus on the visual aspects of weather effects or predication modeling and can rarely interact with objects or aircraft in a simulation. Though this capability can be offered by large flight simulators, their costs are most often prohibitive. Fortunately, new advancements in the modeling and simulation industry have made it possible to create affordable PC-based simulators that can work with exterior data to support critical tasks without intense hardware requirements. PLANET LLC proposes to expand its current work on realistic physics-based 3D training tools to develop a new tool to simulate weather conditions. Using PLANET's Hypercosm software and with experts in computational fluid dynamics (CFD) from its sister company, Orbital Technologies Corporation, the results from CFD analysis on aircraft under specific weather conditions would be used to feed Hypercosm 3D simulations with physics-based behaviors. The 3D simulation would be generated in real-time using the forces on the aircraft and the effects of different variables, such as wind speed and direction, would be shown. The delivery would be in Hypercosm's web-based 3D format, meaning that simulations could be viewed at any time or place with computer access.

Title:Techniques, Processes, And Tools For Implementing An Integrated Corrosion Detection System
Abstract:Under SBIR Program Solicitation FY07.1, Navy Topic N07-038 entitled, "Techniques, Processes and Tools for Implementing an Integrated Corrosion Detection System", the NAVY has identified a need for the development of techniques, processes and tools for corrosion detection in large military aircraft. The technical problem being addressed in Navy Topic N07-038 arises from the limitations of the current methods of detecting corrosion in large military aircraft by manual inspection of aircraft surfaces by maintainers in the field and at the depot level. Furthermore, these schedule-based detection methods are time consuming and quality of inspection is limited to detection by the human eye. Also, inspection in non line-of sight and tight spaces is not possible without a borescope or other item of non-destructive inspection equipment. To solve these problems, the Navy is seeking methods to identify early signs of corrosion and alert maintainers for detailed inspection based on physics of failure. In response to this need, Laser and Plasma Technologies, Inc. (LPT) proposes the use of optical methods such as color change under strain created due to corrosion process, optical scanning method and optical shearography to develop an efficient, compact system for corrosion detection as well as the application of physics of failure to this problem. The Investigators anticipate success in both the development of early detection system using novel optical methods and its relationship to structural integrity based on the unique symbiosis in capabilities found in the collaboration between LPT and the Subcontractor to the program, the University of Virginia.

Title:Low-Cost Self-Assembly Technique for a Fully-Integrated Light-Weight Metal RubberT Corrosion Sensor System
Abstract:NanoSonic proposes to develop a durable fully-integrated nanostructured sensor to detect surface-related phenomena, such as wear/corrosion, of military aircraft; specifically, a Metal Rubber(TM) corrosion detection system. Metal RubberT (MRT) is a multifunctional nanostructured material that can have high electrical-conductivity, low-modulus, and low mass-density. NanoSonic plans to integrate the non-invasive MRT sensor system onto aircraft structures to detect chemical modifications and microstructural breakdown from corrosion. The in-situ MRT corrosion detection system would be fully-integrated onto the aircraft surface as a coating or conformal appliqu for a self-assessing "smart" coating system that would reduce timely visual inspections, thus reducing system maintenance costs and improving the overall safety. NanoSonic has established techniques to control multiple constitutive material properties in coatings and free-standing materials using molecular layer-by-layer ESA processes, by varying the type, size, and structure of incorporated molecules. This low-cost method would be used to fabricate conformal corrosion sensor materials that could be applied on existing structural components as coatings or appliqus. MRTM sensors and interconnect elements may be incorporated into the coating (or appliqu) via patterning to allow for a wire-free, in-situ corrosion detection system. Integrating co-located interconnected RF circuits would allow for remote RF mapping of the aircraft surface structural properties.

Title:3-D Airspeed Sensor for All Phases of Rotorcraft Operations
Abstract:Current airspeed measurement systems on military and civilian rotorcraft pose a safety hazard and operational liability because the measurement of airspeeds is unreliable below 40 kts, because only forward air speed can be measured, and because the system cannot provide a directional component to the air flow. Using patented and combat proven thermal anemometer technology, AeroTech will develop an air speed sensor that will provide accurate airspeed measurements in all three axes within rotor downwash; will detect and measure airspeeds down to "creeping flow" (less than 0.1m/s), that will provide an airflow angle; and that will be low cost, low weight, and have low power consumption. The sensor will be rugged, low maintenance, and be able to be retrofitted into current helicopter avionics systems. Accurate, three axes measurements of low airspeeds and airflow direction will assist pilots in precision maneuvering in combat operations, weapons employment, landing on ships, and landing in rough and dense terrain. The Phase I feasibility analysis and limited laboratory testing will demonstrate that the proposed concept meets the requirements and will provide the foundation for development of the sensor in Phase II.

Title:Three-axis Low Airspeed, Low-Cost Air Data Sensor for Rotorcraft
Abstract:Current air data systems include standard pitot systems as well as flush port pressure sensors, which suffer from many shortfalls. Installation and calibration must be tailored to each airframe, and airframe modifications may require recalibration of the air data system. This can be costly and time consuming. At high angles of attack the air data is significantly degraded. Rotorcrafts are particularly susceptible to the degradation in capability below 40 knots due to sensitivity issues and the effect of rotor downwash. All of these faults become highly evident during low speed maneuvers, automatic flight control support and weapons delivery. Michigan Aerospace Corporation proposes to determine and demonstrate the performance of a Rotorcraft Optical Air Data System (ROADS) capable of three-axis airspeed measurements at speeds below and above 40 knots. The system will be capable of measurements in longitudinal, vertical and lateral flight with no degradation. It will also simultaneously make wind measurements inside and outside of the down wash to aid weapons delivery. In addition, the proposed system can be produced at a much lower cost than even five years ago due to significant advances at Michigan Aerospace and its laser and detector vendors.

Title:Three-axis Low Airspeed, Low-Cost Air Data Sensor for Rotorcraft
Abstract:A three-axis low airspeed, low-cost air data sensor (3x-LAS) using hot-film gages will be developed for helicopter applications. Low speed flight consisting of hover, forward, rearward, and lateral motion impacts important flight-operation problems involving vehicle performance, flight stability and control, structural load, fatigue life, and pilot action. This segment of the helicopter flight is critical in terms of safety and safely expending the maneuvering envelope during maneuvers such as approach, rapid descent, hover, sideward, and rearward flight. Low airspeed measurement is also important on attack helicopters for low speed targeting. Traditional airspeed systems experience serious limitations in accuracy at air speeds below 40 knots. The proposed innovation, based on the use of high-frequency response hot-film gages will measure airspeed all the way to zero knots. The 3x-LAS will be developed both as an embedded, non-intrusive system and a stand-alone probe which could be easily retrofitted with minimal calibration requirements and without having to make significant structural changes to the vehicle. 3x-LAS will be ruggedized to deal with harsh environment for an acceptable all-weather operation. Other applications include aerospace and ground vehicles, submarines, ships, and measurements in the atmosphere, ocean, and in internal flows.

Title:Close-Coupled Fuel Injector/Flameholder Concept Featuring Direct Fuel Injection Into Flameholder Wake
Abstract:Close-coupled fuel injector/flameholders used in modern augmentors face difficult challenges in static stability due to higher airflow velocities and higher levels of vitiation than past augmentors. In addition, close-coupled fuel injection schemes typically employ jet-in-crossflow methods to adequately penetrate and mix the fuel with the airstream, but have difficulty providing sufficient fuel to the flameholder wake to anchor the flame. In this SBIR program, CFDRC proposes to investigate novel fuel injection concepts that inject a small percentage (~10%) of the fuel directly into the flameholder wake to control the wake fuel-air ratio, without disrupting the wake recirculation zone. In Phase I, a combined numerical/experimental program is proposed that will study preliminary designs. Various methods of injecting the wake fuelflow will be studied numerically, using advanced 3D RANS and LES methods, and the best concept(s) selected for single flameholder testing. To show feasibility, blowout testing at realistic augmentor conditions will be performed at existing Energy Research Consultants (ERC) facilities. In Phase I Option, additional analysis/testing will be performed to study alternative fuel injection schemes. In Phase II, optimized designs that include flameholder cooling flow will be developed and tested, followed by sector testing of the concept at General Electric in Phase IIe. If successfully demonstrated to GE satisfaction, GE will consider full engine testing of the concept in Phase III.

Title:Flame Holder Designs for Improved Augmentor Stability
Abstract:Augmentor stability is critical to the operational performance of military aircraft that rely on gas turbine propulsion. Compared to early augmentor designs, the distance between the point of fuel injection and the flame holder has become progressively shorter in modern augmentors. These so called close-coupled designs help avoid autoignition issues associated with higher augmentor inlet temperatures. A negative aspect of such close-coupled designs is that the fuel is not optimally mixed in the flame holding region, leading to static and dynamic stability issues. Creare and our partners propose a new close-coupled augmentor flame holder design that will greatly extend stability margins, especially in the high altitude, low Mach (Ma) number part of the flight envelope where stability issues are of greatest concern. During Phase I we will demonstrate our flame holder concept in an augmentor test facility. We will also conduct numerical analysis to predict the fuel distribution in our novel design and the anticipated improvement in static stability. Based on the experimental and analytical results, we will develop optimized designs for further development and testing during Phase II.

Title:Novel Flame Holder Design Providing Enhanced Stability in Gas Turbine Augmentors
Abstract:A concept for improving ignition, stabilization, and lean blow out of augmentor flameholders by using a microwave generated air plasma as a continuous ignition source is proposed. The proposed effort will focus primarily on testing of small scale flameholders. Initial testing will establish the extent of performance improvements available by comparing test results with published data on similar flameholders using pre-mixed gaseous fuels at representative, ambient pressure/temperature airflow velocities. Subsequent testing will utilize liquid fuels to optimize spray nozzle and/or spray bar locations, first at ambient pressure/temperature airflow velocities, and then followed by vitiated heated airflows in a Phase I Option. A summary of specific design parameters will be generated based on test results, and applicable scaling parameters will be developed for use in numerical simulation studies and larger scale systems.

Title:20/20 Immersive Display System Based on Eye Tracking
Abstract:The U.S. military relies heavily on immersive simulations to train pilots and other war fighters. However, it is not currently possible to display immersive environments in a manner that represents a real world scene viewed with 20/20 eyesight. The effect is that pilots train as if they have less than 20/20 eyesight. Simulations can be tailored to compensate for this reduced resolution, but this produces inaccuracies in the simulated world. What is needed is a method to display the immersive world at a resolution that better simulates the real world. Cybernet proposes to leverage previous work in helmet mounted display (HMD) design, eye tracking, and small robotic systems to develop an HMD that provides very high resolution imagery at the point where the fovea is focused and lower resolution imagery throughout the rest of the scene. As we have done in the past, we will leverage COTS projection displays to develop the overall displays and our existing eye tracking technology to monitor how to move the high-resolution screen to keep it aligned with the fovea.

Title:20/20 Immersive Display System Based on Eye Tracking
Abstract:Currently, many flight simulators are based on projection screens arranged in a generally hemispherical globe or faceted surface around the simulated cockpit. Typically, a series of separate projectors are aligned such that the video panels or projections overlap to give the illusion of a continuous image. Most of these systems do not offer 20/20 visual experience, as the total number of pixels required to do so is enormous. As a result, resolutions on the order of 20/60 to 20/80 are common in current simulators. OASYS is proposing a modular approach to realizing an immersive foveal-tracked helmet-mounted display (FT-HMD). The technical approach starts with a single ocular eyepiece channel which includes two image sources, with one WFOV image source for peripheral viewing, and a second, narrower FOV video source for the high resolution insert FOV. The optical channel also includes a means of translating the Insert FOV across the larger, lower resolution Wide Channel FOV by means of a beam steering device such as a Fast Steering Mirror (FSM). Direction of the insert image motion is governed by data from an eye tracker which is also coupled into the optical system.

Title:Real-Time Modeling of Rotor Induced Flow with Shipboard Interactions
Abstract:Rotor induced flow modeling is a central part for almost every aspect of rotorcraft simulation and analysis. There are, however, challenges in the accurately predicting the unsteady rotor wake transportation, especially when it interacts with aerodynamic disturbances from nearby aerodynamic bodies such as a fuselage, a ground surface, or a ship landing deck. This proposal aims to develop an adequate real-time rotor induced flow model for shipboard flight simulation. The model to be developed will be a physics-based viscous vortex wake model that can properly capture the effects of the rotor/ship interaction under shipboard operating conditions. It is also proposed to develop a formulation and a set of algorithms to derive an efficient real-time finite state induced flow model from the high fidelity viscous vortex simulation in support of flight simulation.

Title:High Fidelity, Real-Time, Rotor Wake Module with Shipboard Interactions
Abstract:Continuum Dynamics, Inc. has recently developed breakthrough technologies that allow real-time solutions of full-span, free-vortex rotor wake models coupled with fast panel fuselage/empennage models. These technologies have been incorporated into aerodynamic modules for integration into flight simulation software environments throughout the rotorcraft industry, providing unprecedented modeling capabilities for both real time and engineering analyses. The proposed effort will enhance these models with improved methods for physics-based modeling of shipboard operations, resulting in an advanced rotor aerodynamic module allowing detailed prediction of the three-dimensional, unsteady rotor-induced flow field, including complex multi-rotor and wake/fuselage interactions, in challenging flight regimes such as vertical descent, autorotation, sideward flight and ground effect. Key innovations to be developed as part of the proposed program include a novel approach for a real-time, free-vortex rotor wake/CFD-based ship airwake solution with full wake-on-wake interactions. In addition, a hierarchy of improved real-time, physics-based methods for modeling partial ground effect, ship motion, and wake/fuselage interactions will be developed, with emphasis on flexible, robust modules that may be installed across multiple helicopter simulations and will be scalable to leverage increasing capable computer hardware. The end product will be incorporated into Navy flight trainers providing unprecedented high fidelity flight simulation for shipboard operations.

Abstract:This SBIR Phase I project proposes to use overset grid HRLES (Hybrid RANS/LES) approach to simulate helicopter shipboard operations. After obtaining the computational results at a set of training points with this robust but computationally intensive approach, the principal basis functions of the solutions will be extracted from the numerical results with the POD (Proper Orthogonal Decomposition) technique. Instead of using the more popular Galerkin projections, D&P LLC proposes to use the RSM (Response Surface Methodology)/NN (Neural Networks) approach to further construct a robust reduced-order model of rotor induced flow with shipboard interactions for use in a real-time simulation. The capabilities and limitations of these methods for real-time modeling of rotor induced flow with shipboard interactions will be demonstrated through a feasibility study.

Title:Tactile Situational Awareness System (TSAS)
Abstract:The Tactile Situational Awareness System (TSAS) proposed by Chesapeake Technology International (CTI) will provide for the development of an Tactile Distributed Interface Subsystem (TDIS) that receives data from any available on-board navigation systems, augments that data with an embedded inertial measurement unit utilizing micro-electro-mechanical system (MEMS) technology, develops the correct tactile display requirements in real-time, and uses those results to drive the tactors using the included analog output circuits as required. The TDIS proposed by CTI will interface completely with tactors that either exist currently of will be developed as part of this SBIR. CTI's goal is to utilize existing tactor technologies to the greatest extent possible. Much time, effort, and money has been spent already in the development of tactors, tactor technology, and tactor activation algorithms. Per the stated goals of the SBIR, CTI aims to "identify . and integrate a small, lightweight, multi-frequency tactor". CTI will incorporate this technology into an integrated tactile distributed system that fully satisfies the TSAS SBIR requirements.

Title:Tactile Situational Awareness System (TSAS)
Abstract:Cybernet proposes to develop a tactor that can alter its mechanical compliance. This variable-compliance enabled tactor will stimulate a range of frequencies and amplitudes efficiently. We can then tune the device to optimally overcome the damping properties human skin.By improving the efficiency, we can also drive a larger tactor, which will provide greater skin contact area, thus a larger amount of stimulation. We will do this using multiple actuators per tactor. One actuator will generate vibratory motion while the other will alter the mechanical compliance of the system. Our main point of distinction is that current tactors have a fixed resonant frequency. This limits the range of efficiently achievable frequencies and amplitudes. Also, tactors with a fixed resonant or drive frequency may saturate certain mechanoreceptors, decreasing their sensitivity to stimuli. We propose to develop a tactor that can change its mechanical compliance, and thus its resonant frequency, so we can resonate efficiently at a range of frequencies. Finally, we will provide tools for aircraft integration and tactile profile development.

Title:Tactile Situational Awareness System (TSAS)
Abstract:Spatial disorientation (SD) and the subsequent loss of situation awareness account for a significant percentage of fatal mishaps in aviation. SD typically occurs when visual references are compromised, and the pilot's vestibular and somatosensory (tactile) sensations no longer provide accurate gravity vector information due to changing acceleration and gravitational forces. Under these conditions, a pilot must rely on instrumentation to fly the aircraft, often with information that appears to be contrary to what their body is sensing. The objective of this proposed SBIR effort is to develop a new generation tactile sensory display to enhance pilot special awareness in all phases of flight. This Tactile Situational Awareness System (TSAS) will comprise of a processor integrated with current aircraft sensors, and a garment housing a number of vibrotactile transducers (Tactors). EAI proposes various approached to reducing the size and improving the performance of current generation tactors, so that they can produce a strong vibratory stimuli with amplitude control across a wide frequency range. EAI will also address the overall system design and integration, including controller, processor and software mapping for the TSAS process.

Title:Content-Based Multimodality Image Class
Abstract:Current military surveillance platforms carry a wide range of sensor systems to permit target imaging under a wide variety of operational and atmospheric conditions. These disparate image sensors provide markedly different depictions of the same target, placing severe demands on the image analyst and greatly complicating development of automated methods for target classification. Existing methods of automated image matching typically rely on some form of correlation or template matching performed on the image or in the feature space-a very difficult process for images obtained from multiple sensor modalities. We propose to develop a novel methodology for target classification and content-based image retrieval that incorporates novel feature extraction and target classification methods based on recent developments in computer vision. During the course of this project, we will develop a prototype version of the algorithms and demonstrate their performance on a variety of ISAR, SAR, and electro-optic images. We will also design an open architecture database that can be used for rapid, automated image retrieval.

Title:Inverse Synthetic Aperture Radar (ISAR) Imagery Feature Extraction and Database
Abstract:The U.S. military uses a wide range of sensing modalities for collecting data with which to perform automatic target recognition (ATR) and classification. ATR is a crucial capability for today's weapons systems and is used for guiding smart munitions as well as tracking assets or entities of interest. The available sensor modalities include Synthetic Aperture Radar (SAR), Inverse SAR (ISAR), High Resolution Radar (HRR), and Electro-Optical/Infrared (EO/IR), among others. While significant ATR packages have been researched and developed for the individual sensor modalities, no significant effort has been undertaken to create a single ATR method to extract information from all of these disparate data sources. Cybernet proposes to leverage an orientation invariant ATR technique that we developed for EO/IR data for the Navy to develop a new ATR system for use with all data types. This technique combines the power of modern computer graphics with standard ATR concepts to create a very flexible recognition and classification system.

Title:SMART - System for MARitime Targets Recognition and Retrieval
Abstract:We propose to research and design a System for MARitime Targets Recognition and Retrieval. SMART will significantly advance ISAR/Electric-Optics-based ship detection and identification. Unlike existing solutions which focus on the image processing techniques only, the proposed solution integrates image classification, data simulation, and data fusion to achieve reliable and accurate target recognition and retrieval. One key innovation of SMART is its digital vessel model constructor. The vessel model can be constructed off-line and updated when new information concerning the target is available, and when working along with an image simulator, can be used to simulate reference images, which will be compared with the acquired images. Based on the image similarity, and classification results of the acquired images, SMART achieves more reliable and accurate target identification than conventional solutions. The vessel model also bridges the gaps caused by disparate sources and other factors such as view angle and illumination. Images from disparate sources, which are difficult to be compared directly, can be matched with each other through the vessel model. In this fashion, SMART achieves flexible and effective target retrieval. SMART will provide a suite of methods for image retrieval and model-based retrieval.

Title:Multiscale Feature Extraction and Matching for Content-based Multi-modality Sensor Database Retrieval
Abstract:Rapid, accurate target identification is a key component of force protection and accurate munitions delivery in modern warfare. However, the wide range of imaging modalities, from EO/IR sensors to SAR/ISAR sensors can present significant challenges and strains on the warfighter tasked with target identification. Rapid automated target identification methods that can narrow the scope of possibilities would be a major boon in reducing requirements on the warfighter, improving his efficiency. However, reliable feature matching across multiple sensing modalities presents novel challenges. For robust, reliable multi-modality image searching and matching, we must bring several technologies together. Multiscale feature matching methods can help accelerate the matching process, while novel statistical metrics can significantly aid cross-modality matching and improve robustness to extended operating conditions. It may be necessary to not only match hierarchically against coarse feature representations and the full feature set, but also to match the observed 2D imagery against 3D target Scientific Systems Company, Inc. is proposing an innovative multiscale, multi-modality image database methodology. Our approach incorporates: multiscale matching technology inspired by the Fast Multipole Methods exploited for rapid physics simulations of multi-body electromagnetics and gravitation, statistical matching metrics to enhance invariance to scaling, illumination, resolution, occlusion and other sources of variability, and methodologies developed by the Principal Investigator, among others for robust multiscale, structure-based, cross-modality association and registration. We believe our approach will significantly aid the warfighter in rapidly identifying and eliminating potential threats, relieving him of much of the burden of target identification.

Abstract:CG2 will design software tools that will extract the light features directly from the night source imagery. This will provide the most accurate placement of light features and seamless correlation with the ground texture that is used in the simulated synthetic environment. Our objective is to provide a system that can identify light features within the imagery, identify the geo-specific location, derive the light feature attributes, generate the light model and/or light map, and insert the light model into the geo-specific database with the correct meta-data and attribution for proper real-time behavior. The system design will accommodate light features placed on terrain as well as lights on man-made features such as buildings. This approach will be highly reliant on image processing, and image processing is computationally intensive. CG2 will investigate how to utilize the latest FPGA and shader technologies to accelerate the point light generation process. CG2 will provide modifications to the real-time rendering algorithms to provide dynamic light behaviors using shader algorithms.

Title:Geospecific Night Imagery for Real-time Training Simulators
Abstract:At present, display of nighttime lighting is primarily geotypical because of the cost to generate geospecific databases manually. However, the combination of two technologies can permit automatic extraction of light source data, including latitude, longitude, and elevation. These two technologies are aerial photogrammetry and pattern recognition. As part of a previous Phase II SBIR effort, DVC developed software to extract buildings, trees, and water features from 2D top-down imagery. In addition, software was developed to detect and remove time specific artifacts, such as shadows, vehicles, and both fixed wing aircraft and helicopters. This experience puts DVC in an excellent position to successfully meet the requirements of this SBIR. Diamond Visionics will provide useful solutions to address the challenges stated above based on our extensive background in the extraction of objects from 2D imagery. In Phase I, Diamond Visionics will develop a proof-of-concept PC-based software application capable of automatically extracting light source data from 2D imagery. The resulting data will be saved in a format generally utilized by both the GIS and training communities.

Title:Geospecific Night Imagery for Real-time Training Simulators
Abstract:Renaissance Sciences Corporation (RSC), Terrain Experts, Inc., Harris Corp., and L3 propose a software system that procedurally derives geospecific cultural lighting from night imagery and supplemental data sources, and incorporates the resulting raster imagery and vector data into runtime databases for training simulators. Environmental lighting from artificial (`cultural`) sources, one of the most important night-time phenomena, is generally not represented by modern training systems for either out-the-window or sensor views. The extraction of geospecific cultural lighting from night imagery as well as its procedural generation is an effort to make the option of rendering light patterns from populated areas a reality. This novel technology will have decisive advantages over current state-of-the-art database generation tools, which do not take advantage of night imagery source data and other sources from which geospecific cultural lighting can be derived.

Title:Geospecific Night Imagery for Real-time Training Simulators
Abstract:To meet future JSF programmatic needs and to augment SOF mission planning and training capability, SimWright proposes eight trade studies and a risk mitigation program leading to a system design to generate geo-specific terrain databases. The eight trades studies are characterized as: - Night Imagery Sources Study - Street Light Feature Extraction Feasibility Study - Tower Feature Extraction Feasibility Study - Imagery Correlation Feasibility Study - Moving/Blinking/Occlusion Detection Feasibility Study - Shader Feasibility Study - DBGS Input Requirements Study - Day for Night Feasibility Study. Preliminary investigation suggests no known sources of night time geo-specific terrain data. Having no night time geo-specific data is an enormous risk to developing stereographic feature extraction algorithms for geo-specific night time terrain databases. SimWright will have approximately 1 square mile of night imagery of Destin FL., prior to Phase I award. Imagery correlation can begin right at the beginning of the program. SimWright's CityClick framework is extensible for rapid prototyping of light feature extraction capability. We will investigate both manual and automatic feature extraction for major trade analyses, algorithmic verification, and software prototyping. DBGS formats, input and compatibility issues with IG pipelines will be investigated as part of overall risk reduction program.

Title:Advanced Liquid Surface Tracking Software for Predicting Atomization in Gas Turbine Combustors and Augmentors
Abstract:The atomization of liquid fuels is a key process in gas turbine engines and augmentors, directly influencing combustion and thus engine performance. While adequate models exist for the secondary atomization, the crucial initial breakup is not well understood and predictive numerical simulation tools to analyze the process in detail do not exist. In this project, we propose to apply the recently developed Refined Level Set Grid (RLSG) to the primary atomization problem. This method, in a detached code, resolves and tracks all relevant phase interface length scales on a separate, locally refined grid. The RLSG code is coupled to the flow solver via a multi-code coupling environment, thereby ensuring easy portability and expandability. The resulting software package has been successfully applied to several two-phase flow benchmarks and is able to predict the observed physical breakup mechanisms during coaxial atomization. In the project's initial phase, we will access the capability of the proposed software framework to predict the atomization of liquid jets in cross-flow under conditions relevant to gas turbines and augmentors using experimental data in the near- and far-field. The data will then be assessed for its suitability to derive Large Eddy Simulation models for primary atomization.

Title:Advanced Liquid Surface Tracking Software for Predicting Atomization in Gas Turbine Combustors and Augmentors
Abstract:Recently developed gas/liquid (G/L) methodology, being used for cavitating flow problems, and extended for all-speed operability using preconditioning, will be used to analyze fuel jet atomization in high-speed military gas turbines. This methodology can capture G/L interfaces, and using multi-element unstructured numerics in conjunction with grid adaptation, will resolve G/L shear layer details needed for accurate atomization predictions. Previous primary breakup studies using traditional VOF methodology in a structured grid code, used advanced correlations to predict local droplet formation rates and sizes. Such results will be greatly improved using the new G/L methodology and refined grids along the interface. In this proposed effort, we will demonstrate the applicability of the new G/L approach for tracking the liquid fuel jet in problems typifying gas turbine fuel injection processes. We will also exhibit how grid adaptation can be used to enhance overall accuracy. Primary work will entail implementing the detailed primary breakup models that we have used earlier into the new G/L framework, and demonstrating how we can predict localized atomization rates and droplet sizes along a fuel jet interface. In Phase II, we will focus on validation using full-scale, JSF relevant, gas turbine data sets.

Title:Composite Spray Model for Augmentor Fuel Distribution Prediction
Abstract:Augmentor static stability is critical to the operational performance of military systems that rely on gas turbine propulsion. Compared to early augmentor designs, the distance between the point of fuel injection and the reaction zone has become progressively shorter for modern augmentor designs, which can result in fuel droplets penetrating the reaction zone and variations in fuel jet penetration that can significantly impact the fuel distribution and in turn, engine stability. Highly-resolved modeling and simulation of fuel sprays is far too expensive for even the fastest of modern computers. In this project, we will develop a modeling technique that combines the Volume of Fluid method (VOF) with the Discrete Particle Method (DPM). We will take advantage of VOF's ability to accurately describe the behavior of the spray in the dense region near the injector and marry it with the efficiency of the DPM method in regions of sparse droplet population far downstream of the injector. By combining the two methods in this fashion, we will greatly reduce the computational cost associated with accurate fuel spray modeling. We will utilize high-resolution VOF simulations as well as experimental data of a jet in cross-flow geometry to validate and benchmark our approach.

Title:Three-Dimensional Control Panel Simulation
Abstract: The Navy requires a virtual haptic instrument panel device that can faithfully replicate the look and feel of aircraft instrument panels. There are a number of approaches that can be explored to develop a workable technology. These range from rather mundane approaches that utilize existing components to more exotic/innovative approaches that require significant research and experimentation For this application, there are two technology areas that must be addressed. The first is the automated extraction of 3D panel model and texture data. This can be accomplished with image-based modeling or by using active methods like laser range scanning. The second technology area is the device or device-set that presents the panel haptically to the user. Cybernet proposes a multi-tier exploratory research process that evaluates a number of VHIP approaches by first generating a list of possible approaches, and then weeding out the less desirable ones based on a successively increasingly rigorous elimination process steps beginning with paper-evaluation of the initial candidate list and finishing with the evaluation of prototyped hardware. Candidates concepts include Force-feedback gloves, plug-in switch modules, 3D tactile raster displays, instrument carousels, and combination technologies.

Title:Three-Dimensional Control Panel Simulation using Programmable Tactile Display System
Abstract:Current mission rehearsal trainers are custom physical mock-ups for each cockpit or operator interface training device, which provides the correct tactile feel, but since each mock up can only simulate one cockpit, these mock-ups are expensive, space-consuming, and inflexible. Virtual Reality (VR) based trainers are flexible in that one system can simulate a variety of cockpits and training scenarios. In this proposed effort we intend to develop a VR based 3D control panel simulation using a programmable tactile display system with novel actuator arrays which can simulate a variety of control panels. Desirable attributes of this tactile system are that it should be unobtrusive and seamlessly integrated into a glove, which lead to the requirements that it should be portable, wireless, light-weight, and low power. Our primary objective for Phase 1 is to perform technical, human factors and end user research necessary to produce the design specifications, develop our actuator system, simulate two representative control panels with stereoscopic display and generate a preliminary design for a proof-of-concept 3D control panel system. In addition, we will develop a detailed work plan for development and testing of such a system.

Title:Innovative Approaches for Improving the Hot/Wet Performance of Polyimide Matrix Composites
Abstract:The development of AFR-PE-4E polyimide composites has enabled the incorporation of high-temperature composite structures in military jet engines. The use of these composite components significantly reduces weight and results in increased engine performance. In order to take full advantage of this "new" composite system, an increase in the hot/wet performance of the AFR-PE-4E resin system must be achieved with minimal scatter in the design allowable database. Current F135 and F136 engine systems slated for the Joint Strike Fighter (JSF) require composite ducts that could total up to 300 pounds per engine. AFR-PE-4E composite has been selected for these structures and this will require a continuous service temperature in excess of 316C (600F) while retaining maximum physical strength. By combining Maverick's innovative technology and experienced resources with GE Aviation, Pratt & Whitney, and Vought Aircraft, a strong technical team has been established to accelerate the development of an "improved" version of AFR-PE-4E polyimide resin for aggressive engine environments. The hot/wet performance and processing characteristics will be determined for each new candidate resin. By using a team approach, a successful Maverick Phase I SBIR program will provide "novel"AFR-PE-4E technology that will have a rapid path of insertion onto the JSF platform.

Abstract:MNB Technologies' unique approach enables fully automated ad hoc clustering of hardware accelerated notebook computers into mission-focused high performance service oriented architectures. Initially targeting computationally intensive applications such as genetic algorithm-based route planning and rigerous image registration, the new system family will ultimately find strategically important use across the entire warfighting community and a wide range of civilian applications. The hardware side of the approach uses small footprint (PCMCIA and Drive Bay) FPGA-based accelerators that communicate not only through their hosts' Ethernet but also through a novel NUMA-like shared memory enabled by a switchless/hubless optical ring local network. Innovative middleware automates cluster setup, configuration, service publication & discovery, and automatic fault detection & rollover. The result is a high performance, high availability system suitable for mission-critical use with forward deployed forces. Outside the DoD the system brings HPC class performance to disadvantaged users and to field-deployed applications requiring robust portable execution platforms, for example: modeling & simulation for disaster management, portable bio-analysis laboratories, and earth-resource exploration.

Abstract:Rydal Research proposes to research and demonstrate the feasibility of developing an FPGA-based Algorithm Accelerator for high-performance Navy applications. The accelerator will be developed using Rydal's automated algorithm-to-hardware design system. This system quickly produces VHDL designs guaranteed to be optimized in terms of characteristics such as speed, size, power, or any combination of these.

The system is capable of easily translating large, complex designs and it is also able to partition the application over multiple FPGAs. The rapid design process will allow critical parts of candidate designs to be ported to an actual FPGA and demonstrated in Phase I to verify hardware simulation predictions.

Abstract:We propose a novel and integrated approach to inspect the ice and cracks in aircraft structures. It combines the state-of-the-art SH wave EMAT technique, through detailed numerical modeling and instrumentation for data collection, with our record-proven advanced signal processing and pattern classification technique, to detect and characterize the ice and crack problems. The technique has four components: (1) thorough guided wave modal analysis, (2) recently developed two-dimensional (2D) and 3D Boundary Element Method (BEM) for best operational condition selection and defect feature extraction, (3) ultrasonic Shear Horizontal (SH) waves EMAT sensor design and data collection, and (4) advanced signal processing algorithm like nonlinear split-spectrum filter, Principal Component Analysis (PCA) and Learning Vector Quantization (LVQ) for signal-to-noise-ratio enhancement, ice/crack signature extraction, and pattern classification. The proposed system is supported with solid physics models and our innovative statistical signal processing algorithms. It is expected to achieve ultra reliable self-diagnosis capability.

Title:Smart, Universal, and Intelligent Vibration Sensor System
Abstract:To address the Navy need for ultra-reliable ice/crack detection sensor technology, Physical Optics Corporation (POC) proposes to develop a new Smart, Universal, and Intelligent Vibration Sensor (SUNIVIS) system. This proposed device is based on an ultrareliable self-diagnostic acoustic vibration sensor integrating a highly reliable noncontacting wireless communication link for real-time detection, analysis, and prediction. The SUNIVIS will use an innovative torsion vibration sensor with a small low power consuming microcontroller, which has 8-bit processor architecture and 11 channels of analog-to-digital (ADC) at 10 bit resolution, and a serial data interface for the wired communication link at up to 256 Kbps. The wireless link will communicate with ISM 2.4 GHz (or 915 MHz for lower data rates) frequency radio. The innovation in SUNIVIS will enable the self-diagnostic vibration sensors to be installed in unreachable or hazardous areas. In Phase I POC will demonstrate the feasibility of SUNIVIS by demonstrating the detection of ice and cracks in metal and plastic composite sheet without the need to machine contour the lower surface. In Phase II POC plans to develop a fully working sensor system with an inexpensive microcontroller, serial data interface, analog interface, wireless/wired communication interface, and smart reporting embedded software.

Title:Fast Non-Contact Infrared Reflectometer for Fiber Coating Evaluation
Abstract:Ceramic matrix composites (CMCs) have been developed to introduce ceramics in structural parts used in severe environments, such as rocket and jet engines, gas turbines for power plants, heat shields for space vehicles, fusion reactor first wall, aircraft brakes, heat treatment furnaces, etc. The CMCs for jet engines can potentially improve the performance of Joint Strike Fighters and other military engines. The use of CMC will increase the operation temperature of engines and minimize the demand on cooling. The CMCs can be reinforced through coating on reinforcement fibers to increase their strength. The quality production of CMCs on reinforcement fibers requires quality control evaluation of the coatings frequently, accurately, and in larger areas that are not attainable by existing quality evaluation techniques such as scanning electron microscopy, transmission electron microscopy, and auger analysis. New Span Opto-Technology Inc. proposes herein non-contact optical reflectometer for fast nondestructive evaluation of the CMC coatings. The evaluation is also suitable for larger area studies and for non-planar substrates. Multilayer evaluation may also be possible. Phase I research will develop a bench top optical reflectometer system for feasibility demonstration of CMC coating evaluation. Phase II will develop a non-contact optical reflectometer prototype.

Title:Fringing Capacitive Array Sensor for Evaluation of Fiber Coatings
Abstract:To address the U.S. Navy need for technologies/methods of low-cost, rapid nondestructive evaluation (NDE) of fiber coatings for ceramic matrix composites (CMCs), Physical Optics Corporation (POC) proposes to develop a new Fringing Capacitive Array Sensor (FCAS) system. The system is based on recent advances in fringing field sensors (FFSs) and a parameter estimation algorithm for NDE of materials. The innovative and unique structure of the multiwavelength FFS array will enable the FCAS system to rapidly (<5 minutes) evaluate large areas (scalable to specific needs, with a large number of sensor elements) of fiber coatings in one scan. In Phase I POC will demonstrate the feasibility of FCAS by designing a system prototype with 576 electrodes covering three wavelengths (for each wavelength, there is a 4x4 sensor array; each sensor element has six drive and six receive electrodes) and testing it on CMCs with fiber coatings from a CMC fabricator. In Phase II we plan to improve the FCAS system by optimizing the sensor, electronics, and data processing algorithm. We will quantify the measurement results, demonstrate this technique in a commercial fiber coating setting, and characterize coated fiber/fabric/perform samples.

Abstract:Optical spectroscopy has proved to be successful in many industrial analytical applications. Recent successful application of FTIR spectroscopy to monitoring crystalline structure and delamination indicates that this method can be as successfully implemented to monitor properties of CMCs coatings. Small portable FTIR spectrometers are available from Surface Optics Corporation. It was developed for monitoring thin layers on metallic or plastic substrates. This hardware can be potentially customized for line or on-line monitoring of coatings on CMCs. Surface Optics performed on-line installations of FTIR technology for monitoring coatings in industrial settings, and assisted with implementation of this technology at Government labs. SOC has a long working history with the aviation industry to monitor thin films in applications such as monitoring curing of epoxy coatings, verifying its composition measuring thickness of primer coatings, verifying cleanliness and investigation of coatings failure. The other technology to be evaluated is hyperspectral imaging. Surface Optics is a champion in the development of spectral imaging covering spectral regions from visible to far infrared.

Title:Distributed Sensor System Innovations
Abstract:The primary objective of this Phase I SBIR is to develop cost effective distributed sensor systems which will enable the Navy to reduce the total costs of ownership while achieving system performance and reliability goals. The two most significant challenges facing the Navy sensor systems community today are system availability and cost. Current solutions have been very polarized in results in that the cost effective systems have yielded unacceptable availability while higher availability systems are at prohibitive cost levels. Achieving these objectives will require a multifaceted approach that addresses not only the cost of the electronics but adopts scalable simplified system architectures. The approach must develop innovative packaging approaches, facilitate improved sensor manufacturing processes, utilize new sensor technologies that are more cost effectively scaled to higher performance applications, and transition to higher levels of component integration. Extending this capability across multiple sensor systems and the synchronous data fusion of either homogeneous and/or heterogeneous sets of sensors will enable Future Naval Capabilities to realize multi-sensor system processing and provide greatly enhanced detection capabilities while attaining system availability and cost goals.

Abstract:The overall intent of this project is to produce cost-effective component technologies that will facilitate the development of compact sensing nodes which are utilized by deep submergence vector sensing line arrays. The principle application for this effort is targeted for the augmented reliable acoustic path vector sensing line array. In that regard, the Phase I study will develop a prototype compact vector sensor housing together with an integrated omni-directional pressure hydrophone that will (1) meet the electronic noise floor and submergence depth criteria imposed on the prototype device currently in production and (2) be produced at substantially lower costs than the prototype device. These components will be designed using the results from analytical modeling, numerical modeling, and proof-of-principle laboratory experiments. It should be stated that, while this SBIR Phase I project addresses the development of a compact vector sensor housing containing an integrated pressure hydrophone, APS plans to leverage the results from SBIR Topic N07-076 "Naval Device Applications of Relaxor Piezoelectric Single Crystals" to address the development of a compact pressure-gradient hydrophone. The results of both SBIR projects will be used together during Phase II in which a series of prototype vector sensors will be fabricated and tested.

Title:Multiuser Estimation; A Distributed Error Correction Technique for Sensor Networks
Abstract:To ensure the freedom of maneuver for forces moving from the see to inland, surface and subsurface threats including small and fast boats, submarines, and mines should be detected and located. The most effective method to carry out this task is to deploy a large grid of distributed sensors that reports the littoral activities to the command and control units. This approach is already pursued in various Navy programs including Advance Deployable System. One of the major obstacles that limits the abilities of the sensors in a large grid is the short operational range caused by limited power on board and the unfavorable environment. In this proposal, Intelligent Automation, Inc. details a novel approach for sensor nodes in a sensor network that significantly reduces the transmit power requirement, in particular those communicating with acoustic signals through littoral waters. We propose to implement an innovative method called "multiuser estimation" for estimating the received signal from multiple sensors with correlated data. Correlations will occur any time a target is detected by multiple sensors, or if the environmental changes affect the neighboring sensors in a similar way. In our method we use the correlation for correcting errors caused by the noisy channel.

Title:Distributed Sensor System Innovations
Abstract:In order to counter the quiet modern submarine threat, distributed sensor systems require innovative concepts to provide high performance levels cost-effectively. With technical advancements, smarter, more capable sensors can now provide improved performance, long-range, and long-life to achieve cost-effectiveness. Utilizing the Reliable Acoustic Path in deep water, an array of sensors can achieve long range acoustic detection when reliably deployed and moored. The distribution of these sensors over an area requires that they be of reasonably manageable size and weight (e.g., Mk-46) for launch from aircraft and ships. The optimal automatic deployment, descent, and mooring of a highly capable RAP sensor requires a precise sequence of underwater. The design and packaging of the sensor depends upon this sequence. Stability of descent, cable payout, component deployment, bottom impact, and mooring reliability depend upon parameters such as hydrodynamic shape; the changing mass, weight, and buoyancy distribution during with descent; cable-pull-out force; component size and shape; impact velocity; bottom type; and anchor type. The present effort is to develop an optimal, cost-effective means of automatically deploying a large, multi-element array sensor in the deep ocean and mooring this sensor where the ocean bottom depth, slope, and type is unknown.

Title:Marine Environment Deployment of Undersea Sensor Arrays (MEDUSA)
Abstract:Rapid deployment of sensor arrays into deep sea and littoral environments requires reliable mechanisms and payload packaging in order to ensure proper placement and longevity. Additionally, sensor networks require reliable, repeatable coverage areas and spacing. The methods of achieving this can change depending on whether the sensors are deployed singly or as part of a multi-sensor system. TUI proposes to develop two prototype underwater sensor deployment systems, one for individual sensor payload deployment for use in creating distributed networks by deploying individual payloads in desired locations, and one for multiple payload deployment for creating sensor networks by deploying a single package that then autonomously deploys multiple sensor payloads. These systems can be deployed by several means, including air drop, from a submarine's three inch launcher, or via hydro-casting from a surface vessel. Both deployment systems can provide an optical fiber link from the sensor package to a buoy to enable either RF transmission of the sensor data or data logging by a retrievable package. The proposed Marine Environment Deployment of Undersea Sensor Arrays (MEDUSA) system will provide the Navy with a low-cost, reliable, and effective means of rapidly deploying arrays of sensors in the deep see and littoral environments.

Title:Geospatial Knowledge Management Approach to Automated Image Understanding
Abstract:Information processing and knowledge representation are core components of knowledge management applications in C4ISR. Given the explosive growth of image data collection with associated text descriptors in these systems, Automated Image Understanding would advance the cause for automation urgently needed. Video imagery is emerging as a major source for intelligence information as well, especially in rapidly evolving operations. This transition from static to motion imagery is introducing substantial challenges related to the large amounts of data involved, and the corresponding application development requirements. Here, Milcord LLC and our partner intuVision propose to research, design, and build a feasibility prototype of an automated image understanding architecture using a geospatial knowledge management approach. Our approach features fully automated extraction of feature content from diverse sources, storing these features in an innovative integrated geospatial database, establishing the relationships between ancillary data taxonomy classes to build an ontology that defines, belief networks that uses the extracted source content in conjunction with the ontology for automated image understanding. Building our information processing and knowledge representation approach on previous US government funded R&D technologies developed by our team members will leverage these works and give our project a jump start in developing and operational prototype.

Abstract:SET Corporation proposes to design, develop and demonstrate unsupervised algorithms for automatic grouping, classification and characterization of prerecorded or live video streams. Our system integrates algorithms for color, appearance, and motion-based characterization of video segments of possibly variable lengths using unsupervised techniques that allow efficient user interactions. We propose a simultaneous segmentation and parameter learning approach that clusters video segments in an unsupervised manner. A sequence of such video segments forms a video cluster from which, radiometric, statistical, structural and semantic attributes are extracted. The segmentation algorithm is quasi-invariant to viewpoint changes and invariant to variations such as the execution rate of events, resolution of video, rotation and translation. In Phase II, we will integrate a high-level semantic architecture that will provide summarization, indexing and retrieval functionalities.

Title:Information Processing and Knowledge Representation For Automated Image Understanding
Abstract:This Phase I proposal is for evaluating the feasibility of a system for (i) automatic extraction and representation of important attributes of image and video data, and (ii) inference of high level scene descriptions from these attributes. Specifically, the proposed work is aimed at exploring the feasibility of methodically incorporating into a system the capabilities to: (1) discover any salient patterns prevalent in image and video data, (2) learn definitions of complex visual concepts characterized by increasingly complex patterns, (3) recognize their occurrences in previously unseen data, (4) search and retrieve all parts of a video database containing occurrences of previously learned concepts, and (5) provide a summary of a given image/video in terms of spatial and chronological relationships that the concepts recognized in the data exhibit. These capabilities are of significant general importance as they can act as the foundation of solutions to problems in a broad range of contexts such as military, law enforcement, commerce, and the internet usage. Synergistic integration into a single system as proposed will significantly amplify their individual strengths, to yield a powerful tool for information processing and knowledge representation for automated image understanding.

Title:Degradable Taggant
Abstract:Aurora Flight Sciences (AFS), in collaboration with the Worcester Polytechnic Institute (WPI), propose to develop a low-cost, easily deployed, degradable taggant that can be dispersed over a wide area to serve as a witness to activity in the area and for queuing of other sensors. The passive taggant will enable nearly real-time change detection within the treated area using one or more simple optical sensing techniques. In addition to developing the degradable taggant, the AFS-WPI team will also develop a conceptual design for a robust sensor system (including its concept of operation) that can be used to quickly and accurately detect changes in an area of interest that are characteristic of IED emplacement or other asymmetric threat activities.

Title:Activated Chemiluminescent Gels for Intrusion Detection
Abstract:Physical Sciences Inc. (PSI) proposes to develop a self-contained, biodegradable, chemiluminescent hydrogel for applications in covert determination of trespass. The hydrogel will stabilize the generation of light by mimicking a solution-phase environment. PSI's design is expected to yield a pressure-activated passive chemiluminescent signal that will persist at readable luminosities for about 2 weeks, with gradual loss of the signal. PSI's taggant powder will represent a significant advancement over other self-generated lighting systems because it will not present an environmental hazard or leave behind telltale waste. Chemiluminescent gels offer a tunable emission wavelength due to the spectral diversity of fluorophores that can be chosen as the light emitter, or lumophore. During Phase I development we will utilize a red-emitting lumophore. Subsequent development would be to utilize a near-infrared lumophore so that only those wearing night vision goggles can view the taggant response, and/or a green lumophore for enhanced visible detection capability.

Title:Degradable Taggants
Abstract:TIAX proposes an effort to address the two primary technical challenges that need to be resolved in order to develop a robust tagging system to enable near-real time change detection for monitoring of specified routes used by US troops in combat zones. The extreme urgency of this need is starkly clear given the situation in Iraq where roadside bombings using Improvised Explosive Devices (IEDs) are the biggest killer of US troops. These tagging systems can ultimately enable: (i) near-real time detection of indications of Improvised Explosive Device (IED) threats, (ii) collection of movement data by examining tracks in a targeted area, and (iii) identification of entities (e.g., people, vehicles) that were once in the area of interest. The Phase I effort will focus on evaluating the feasibility of the proposed technical solution. Our technical approach is especially designed to accelerate the development process and provide on-the-ground solutions expeditiously. This technology can serve a variety of unmet TTL (Tag, Track and Locate) needs, and has a vast number of potential applications in US military, homeland security, and civilian/commercial markets.

Title:"Jellyfish" Smart Sensor Made With Electroactive Ionic Polymer Nanocomposites
Abstract:This Phase I Navy SBIR effort will examine the design and development feasibility of an underwater biomimetic swimming structure resembling a jellyfish. The proposed underwater biomimetic swimming structure or artificial jellyfish will be fabricated with electroactive ionic polymer Platinum nanocomposites capable of underwater distributed sensing, transduction and actuation. The proposed artificial jellyfish will be a self-contained and relatively buoyant structure including, locomotion in the form of jellyfish propulsion, energy harvesting by mechanoelectric transduction and distributed sensing capabilities. The proposed artificial jellyfish will also house any electronics processing and/or communications package within its bell.

Title:Biomimetic Maneuverable EAP Anti-Submarine Sensor
Abstract:In order to address the U.S. Navy's need for improved tools for use in Anti-Submarine Warfare IST is proposing to develop an advanced acoustic sensing system consisting of networked smart sensor nodes. Each of these sensor nodes will be mobile and able to communicate with nearby sensors to form a reconfigurable network. Sensor mobility will be accomplished using electroactive polymer (EAP) fins located on the sensor's hull. This biomimetic configuration will closely resemble that of the cuttlefish, an animal in the cephalopod order. Slight rippling of these laterally fringing fins along with buoyancy control will provide a dynamic lift that can quickly move the sensor from passive suspension to active propulsion. These sensor nodes will also be able to operate for extended periods by utilizing ocean currents and waves as an energy source from which electrical power can be continuously harvested. This approach will utilize long tentacle-like rolls of EAP material attached to the underside of the sensor hull. When strained these EAP "tentacles" will produce an electric current that can be used to harvest energy from movements occurring in the ocean environment such as currents, waves, and pressure differentials.

Title:'Jellyfish' Smart Sensor
Abstract:This SBIR program will make use of the start-of-the-art electroactive polymers and bio-inspired design of jellyfish for locomotion to develop a smart sensor that combining sensing, energy collecting, electro-elastic actuation and communication in one self-contained autonomous device. For force protection, anti-terrorism and homeland defense mission, there is an urgent need for deployable, distributed field of sensors, analogous to traditional Sonobuoys with an additional function of field persistence. This dictates orders of magnitude reduction in energy requirements to operate the sensors for the requisite operational service life (~six-months). In order to reach this goal, Strategic Polymer Sciences, Inc. (SPS) will develop bio-inspired jellyfish smart sensors in which the electroactive polymer generated shape change will be employed for the locomotion of jellyfish smart sensors, which will markedly reduce the energy requirement for the locomotion and station keep. Recent experimental results also demonstrated that by integrating electroactive polymers with smart electronics, a much higher energy harvesting efficiency can be achieved. In this SBIR program, SPS will integrate these technologies to develop the proposed smart sensors. In Phase I of this program, SPS will develop detailed design and simulation to determine the performance of the jellyfish smart sensors.

Title:High Frequency Broadband Hybrid Transducer/Amplifier
Abstract:Traditionally, the sonar amplifier system has been viewed as the configuration of various independent disciplines; transduction, magnetic compensation and matching, power amplifiers and control. Clearly these disciplines cannot be regarded in isolation and there are significant advantages in designing a complete modular sonar system. This proposal describes a unified approach - a hybrid sonar transducer that includes a compact amplifier, matching magnetics, and control electronics within the transducer housing. The goal is that the total package may be treated as a module for inclusion in a scalable array that can be affixed to, or embedded in, the hull or structure of a small unmanned undersea vehicle or glider, or in the coating of a surface combatant or submarine.

Title:High Frequency Broadband Hybrid Transducer/Amplifier
Abstract:The proposed development will result in a compact, efficient, broadband transducer module including amplifier and wet-end transducer. To facilitate multiple mission requirements, the transducer performance goals are a broad bandwidth (7-30 kHz), compact size on the order of 1/2 wavelength at the center frequency, at least 30 watts output power, and high efficiency. The resulting technology from this work will be a compact, broadband transducer module using new materials and new amplifier technology that will be capable of fulfilling multiple missions. The magnetostrictive transducer will be based on multi-resonant TERFENOL-D concepts and/or a hybrid combination of TERFENOL-D and Galfenol, a new class of structural magnetostrictive materials. The amplifier/electronics development will include a full design for a next generation power module that incorporates high power density wideband gap (state of the art) integrated power conditioning and control capabilities that will have wide impact far beyond the current proposed system. The Phase I effort will demonstrate feasibility of the transducer module concept using models and limited experiments. If successful, the proposed work will result in a compact, broadband transducer module using new materials and new amplifier technology that will be capable of fulfilling multiple missions.

Title:High Frequency Broadband Hybrid Transducer/Amplifier
Abstract: There is a need to develop a broad-bandwidth, efficient, small compact projector module with integral amplifier that can be imbedded in the hull of an unmanned vehicle or in the coating of a surface combatant or submarine. It should also have the capability of a hydrophone for possible use in a communications mode. The modules could be used together to form a conformal array. The transducer should also have a high coupling coefficient, yielding a high power factor and, because of the lower volt-ampere transducer requirement, a smaller power amplifier. This and the need for low frequency performance from a small container has led us to a transducer design which we call the CMX transducer which can be operated with PZT-8 or single crystal piezoelectric material, such as PMN-28%PT. This material has the advantage of considerably higher compliance, coupling coefficient, d constant and strain compared to conventional PZT-8. In this proposal we present FEA modeling results which demonstrate the exceptional performance of the CMX transducer with both PZT-8 and PMN-28%PT and its suitability for the desired application. We propose a program for the development of a practical prototype element and design for the above intended applications.

Title:Naval Device Applications of Relaxor Piezoelectric Single Crystals: Design of a Transducer for Underwater Communications
Abstract:This proposal is concerned with the use of single crystal PMN-PT as a transducer element in underwater communication systems. The high sensitivity and strain capability of these materials makes them unusually appropriate for the demands of small size and high output needed in this application. Developments already underway as an element in active noise reduction earplugs for personnel on the flight decks of aircraft carriers lead naturally to the use of similar transducers for in-the-ear loudspeakers for personnel carrying out underwater missions, particularly in the littoral ocean zones. Such activities are of particular value in communicating with personnel who will wear ear canal insert earphones resistant to water and pressure, and still maintain a high degree of fidelity, frequency and dynamic range for the presentation of transmitted messages. The same or similar elements can also serve as microphones or hydrophones as part of a two-way communications link. The progress and experience we already have in working with PMN-PT has convinced us of the special advantages that this material has when incorporated into small, high output acoustical drivers, and offers an unusual opportunity to design and prototype a transducer for underwater communications.

Title:Naval Device Applications of Relaxor Piezoelectric Single Crystals
Abstract:The overall intent of this project is to develop a series of miniature vector sensors for statically deployed and towed array applications. In each of these applications the sensor will be required to have an operational bandwidth commensurate with the passive ASW frequency range and an electronic noise floor below sea-state zero. In that regard, the Phase I study comprises of an evaluation to (1) determine which type of pressure-gradient hydrophone (i.e., either inertial or diffraction) is best suited for the application and (2) which single crystal transduction mode (i.e., extension or shear) is best suited for miniaturization. These tasks will be accomplished using analytical and numerical models along with proof-of-principle experiments. At the conclusion of Phase I a pre-prototype miniature biaxial vector sensor, suitable for submarine thin-line towed array applications, will be fabricated and tested. During Phase II, several application-specific miniature vector sensors will be fabricated and tested in laboratory and field environments to ascertain their performance under conditions that are consistent with those encountered in situ. The sensors developed during Phase II will contain integrated electronics.

Title:Relaxor Piezoelectric Single Crystals for Guided Wave Pipe Inspection
Abstract:Shipboard piping inspection is a key factor in assessing the sea worthiness of naval craft. Other piping applications such as fuel lines are also critical. Ultrasonic guided waves have recently received much attention for inspecting complex pipelines. Guided wave pipeline inspection is typically carried out by placing an array of piezoceramic or piezocomposite transducers on the pipe and exciting a guided wave that travels along the pipe axis. The technology is currently limited by guided wave penetration power that can be achieved with the current sensing materials. FBS, Inc. proposes applying relaxor based single crystal composite materials to guided wave pipeline inspection for Navy ships. The technology will also be applicable to all other un-piggable pipelines; such as those in the natural oil and gas industry. Single crystals, which have yet to be applied to guided wave applications, may provide a much needed increase in sensor sensitivity, bandwidth, and penetration power, which would in-turn allow increased inspection distances and sensitivity. Increased penetration power would also allow higher frequency guided wave inspections which would increase inspection sensitivity.

Title:Naval Device Applications of Relaxor Piezoelectric Single Crystals
Abstract:This proposed project is for the new application of PMN-PT based piezoelectric crystals. Shear modes of PMN-PT crystals show the supreme properties: k15 <111> poled PMN-PT crystal has a coupling coefficient greater than 0.95 and k36 <011> poled PMN-PT crystal gives a coupling coefficient greater than 0.90. The k36 <011> has a unique re-pole-ability and larger coercive field over 5 kV/cm (2 times higher than <001> poled k33 mode) that more promising for high power projectors. The proposed device is designed to replace the transducer which is being used in a mine counter measure (MCM) application on an autonomous underwater vehicle (AUV). The proposed shear mode transducer will give the following advantages over the existing transducer: insensitive to the hydrostatic pressure (under water depth), compact volume, less reactive load to the system power amplifier and broaden sandwich. The proposed work will investigate these material properties to produce a compact low frequency SONAR projector capable of very high bandwidth. Anticipated work in Phase II would enable the fabrication of the shear mode transducers for military and commercial applications.

Title:Application of Relaxor Piezoelectric Single Crystals for existing underwater communication systems
Abstract:An underwater voice communication system is mandated for all the US naval surface ships and submarines. The current communication system employs two standard transducers a low frequency transducer for long range communication and a high frequency transducer for shorter ranges but with better quality. By exploiting the unique properties of single crystals, this proposal suggests to replace both transducers with a compact single wideband single crystal transducer. In Phase-I Harris will conduct the performance analysis of such a transducer along with the analysis of changes needed to match such a transducer to the existing electronics. A cost analysis, to estimate the potential savings in life cycle costs from the development will also be part of the Phase-I research. Phase -II will focus on developing the full prototype transducer and test procedures for deployment. Once developed, the transducer will not only be suitable for the existing underwater communication system but also will allow new applications that will exploit the wider bandwidth of the transducers.

Title:Piezo Actuator for an EOD Manipulator Arm
Abstract:Honeybee Robotics proposes to develop an ultrasonic actuator using high performance single crystal relaxor piezoelectric materials. These new materials, with strains exceeding 1% and electromechanical coupling exceeding 90%, allow for higher output torques and better efficiencies than possible with previous piezo materials. While traditional ultrasonic actuators are commonly used for micro-positioning applications, we seek to demonstrate that the improvement in the performance capabilities of ultrasonic actuators will enable their use in applications where greater torque, precision control, and demanding volume/weight constraints require novel actuators. The proposed innovation, based on a patent held by Honeybee Robotics, departs from conventional designs for ultrasonic actuators and changes the basic geometry by generating traveling waves on a stator surface. In this manner, a combination of the single crystal relaxor ceramics and amplification by the geometric design of the stator would achieved improved performance of the actuator. Our proposed solution provides a compact actuator with a high torque/volume ratio, fail-safe braking, no required lubrication, and no electromagnetic interference. It will have low mass and few mechanical parts in a simple geometric arrangement. The actuator proposed will also demonstrate benefits with respect to reliability, safety and cost-effectiveness.

Title:Naval Device Applications of Relaxor Piezoelectric Single Crystals
Abstract:This SBIR Proposal addresses the need for improved acoustic performance at the low end of the required ADC MK4 frequency band to ensure countermeasure effectiveness against the ever increasing threat to U.S. submarines. Image Acoustics Inc. has teamed with Ultra Electronics Ocean Systems (UEOS), the current producer of ADC MK 4 countermeasures, to offer a solution that combines a unique new Trioid transducer design with the improved material properties of single crystal. Single crystal's higher electromechanical coupling, higher piezoelectric d constant and lower modulus than conventional piezoelectric ceramic translates to dramatic improvements in bandwidth, transmit voltage response and resonant frequency, respectively. These improved material properties are essential to the enhancement of ADC MK4 low frequency performance, which is currently limited by the material properties of conventional ceramic. The proposed single crystal Trioid transducer is ideally suited for this low frequency application and will enable a fully specification compliant countermeasure with the added bandwidth capability for improved protection of our Navy's most valuable assets. Phase I of this research and development project will demonstrate the feasibility of a practical device and will include transducer design, computer modeling and the fabrication and test of a scaled experimental prototype.

Title:Self-Powered Wireless Acoustic Sensors for Impact Detection and Evaluation
Abstract:The use of acoustics for impact detection and structural health monitoring has been proven successful. Conventional acoustic techniques require multiple acoustic sensors for the impact source location and damage interpretation. In some applications the need for complex interconnections between multiple sensors or sensor arrays and instrumentation can be a problem. For sensors used in harsh environments, wiring between the sensors and the data acquisition/analysis system could be very difficult or even impossible. Recently developed radio frequency identification (RFID) techniques are getting mature, and they offer an effective method for passive remote identification relaying on storing and remotely retrieving data using devices called RFID tags or transponders. In this proposal, Intelligent Automation Inc. (IAI) proposes an innovative wireless acoustic sensor design, which exploits the advantages of both the relaxor piezoelectric single crystal and the RFID technology for impact detection and evaluation of naval structures.

Abstract:KCF Technologies will combine our experience in single-crystal piezoelectric devices and vibration power harvesting to develop ultra-compact vibration power harvesting devices to enable self-powered sensors on aircraft systems. Single-crystal piezoelectric materials enable this technology to meet the challenging weight requirement and power output needs of aircraft applications. Specifically, the high piezoelectric coupling coefficient and elastic compliance enable order-of-magnitude improvements in device power density. This proposed technology builds upon KCF's leadership in vibration power harvesting for industrial and shipboard wireless sensors. The compactness and high power output, directly enabled by single-crystal ferroelectrics, are demanded for aircraft components where weight reductions are critical and high-vibration components are readily available. This device will enable three stages of new and advanced sensors on aircraft; the first stage is self-powered retrofit sensors for condition monitoring. In Phase I, KCF will design and fabricate an ultra-compact vibration power harvester using single-crystal piezoelectric material and demonstrate it powering a miniature autonomous sensor in a simulated aircraft vibration environment. In Phase II, KCF will join with our partners Eaton Aerospace and RLW, Inc. for a system demonstration of self-powered aircraft sensors.

Title:Common Acoustic Communication Module for UUVs
Abstract:MSI has developed a cost-effective method for producing PMN-PT single crystal materials by Solid State Conversion (SSC) of the precursor ceramic. MSI's SSC single crystals have five times greater piezoelectric performance than the conventional hard PZT ceramics used in legacy sonar transmitters. Although PMN-PT melt-grown single crystals are limited by their high cost, MSI expects that SSC single crystals will have similar cost to that of PZT ceramics in quantity. This translates to an enabling capability for Navy sonar transmitter applications. MSI now has the capability, established through recent high performance torpedo homing array programs, to design, build and test broadband sonar transducers made from advanced piezoelectric materials. MSI proposes to bring together these capabilities in SSC single crystal synthesis and broadband sonar transducer design to establish a new, cost-effective, compact and broadband acoustic communications (ACOMMS) capability for Navy Unmanned Underwater Vehicle (UUV) applications. In Phase I, MSI will collaborate with WHOI to design and show a proof-of-concept SSC single crystal ACOMMS transmitter for Navy UUV applications. In Phase II, MSI will refine and demonstrate a Common Acoustic Communications Module (CACM) that can be affordably integrated into a variety of UUV and other underwater platforms.

Title:Naval Device Applications of Relaxor Piezoelectric Single Crystals
Abstract:Planned Wide Aperture Array (WAA) sonar sensors for submarines are neutrally buoyant accelerometers embedded in a compliant hull coating that sense the particle motion of a target signal as it passes through the coating. Existing designs of sensors using conventional piezoelectric ceramic materials are designed to operate in the bandwidth of legacy WAA systems. Single crystal materials, due to their enormous bandwidth and high sensitivity offer the possibility of providing WAA sensors that are dramatically smaller in size and which will have ultra wide bandwidth. This project proposes to design and demonstrate the feasibility of such a ultra wide bandwidth sensor using newly developed single crystal material with improved performance and manufacturability.

Title:Naval Device Applications of Relaxor Piezoelectric Single Crystals
Abstract:Single crystal materials in high drive transducers have been shown to provide significant performance enhancements associated with their power density and broader transmit/receive spectrum coverage. As a result, compared to legacy transducers employing conventional piezoelectric ceramic materials, single crystal transducers can provide orders of magnitude size and weight reduction. This size reduction can be exploited to provide towed array that can survive the high-speed capability of the LCS.

Title:Highly Compact Broadband Acoustic Sources
Abstract:The proposed research is to develop and demonstrate (during Phase 1) a new design concept for active underwater acoustics sources that uses single crystal multilayer ceramics technology in an essential way. The proposed new subcompact acoustic source design will enable maximum broadcast power over wide frequency band. The resulting design would be a fully self-integrated and extremely compact module that is easily scalable and could readily be integrated in a number of AUV's, UUVs, gliders, surface combatants or submarines. Similarly, the self-contained unit will permit integration as an enclosure on the outside of a surface ship or underwater vessel with a minimum number of hull penetrations.

Title:Naval Device Applications of Relaxor Piezoelectric Single Crystals
Abstract:Techno-Sciences, Inc. (TSi), in collaboration with TRS Technologies, Inc. (TRS), and the Department of Aerospace Engineering at the University of Maryland (UMD), proposes to develop an innovative Vibration Based Energy Harvesting (VBEH) Technology using single crystal PMN material. Single crystal PMN materials will be used to convert mechanical deformation into electrical energy and interface with a battery element via appropriate circuitry with the ultimate aim to power electronic devices. The energy harvester will be tuned to expected vibration spectrum of the substructure and small vibrations can be amplified by resonance tuning to achieve large energy extraction capabilities. To the best of our knowledge, this research is the first attempt towards developing a vibration based energy harvester by exploiting superior performance characteristics of new single crystal ferroelectric material, PMN. Our goal is to provide sufficient energy to power naval sensor and small electronic systems.

Title:Low Cost Crystal Transducer Elements for the Next Generation Counter Measure
Abstract:For this Phase I SBIR program, TRS Technologies and Ultra Electronics Ocean Systems (UEOS) will develop tangentially poled single crystal ring transducers for the Next Generation Countermeasure (NGCM), a compact, submarine-launched, smart countermeasure designed to decoy acoustic homing torpedoes. The improved material properties of single crystal enable the design of a small but capable transducer providing significant savings in size, weight and power that will enable the insertion of key technologies/capabilities for the NGCM. To date, crystal transducers for the NGCM have been constructed from segmented rings which are labor intensive and expensive to fabricate. TRS and UEOS will develop tangentially poled ring transducers to greatly simplify the construction and lower the cost of NGCM broadband transducers. The rings will be specially designed through choice of proper aspect ratio and electrode placement to have uniform properties around their circumference. Simplified transducer fabrication will result in a 2.5X lower cost compared to segmented rings with no reduction in performance. During the Phase I program the ring transducers will be characterized for in-water acoustic source level, bandwidth, and beam pattern. In Phase II TRS will optimize and scale-up transducer fabrication and UEOS will integrate the transducers into the NGCM electro-acoustic module.

Title:Submarine Launched Acoustic Communication Buoy using Single Crystal Sonar
Abstract:For this Phase I SBIR program TRS Technologies and Ultra Electronics Ocean Systems (UEOS) will develop 3" diameter single crystal segmented ring transducers for an Acoustic Communications (ACOMMS) buoy with both gateway data transmission and long range tactical paging capability. The buoy will be sized for launch from the submarine signal ejector (SSE). The use of underwater ACOMMS has been limited by the deficiencies of conventional ceramic based sonar transducers in terms of data rate, range, and device size. With conventional ceramic, gateway data transmission transducers require high frequencies and broad bandwidth to achieve high data rates; however, use of high frequencies limits the transmission range. Tactical pagers require long ranges and therefore low frequencies, leading to large device sizes. TRS and UEOS will address this problem by developing a single, very broadband (2 octave) crystal transducer with high source level for long range paging and high data rate gateway functions in one compact device. TRS will optimize crystal segment aspect ratio and orientation to maximize transducer bandwidth. UEOS will test the transducer in water. In Phase II, transducers will be integrated into an SSE compatible buoy design supplying the Navy with a capability it does not currently have.

Title:Single Crystal 1-3 Composite Projectors for MCM Applications
Abstract:Current piezoelectric ceramic composites used for mid-range (100-200 kHz) for ASW and MCM applications have a number of drawbacks including size, bandwidth, and stress rods. Single crystal PMN-PT has an inherently higher stress limit than ceramics, though until recently techniques of dicing the material did not allow this limit to be reached. With new techniques, dynamic stresses of 50 MPa are possible, potentially providing up to 14 dB higher source level than PZT with a much wider bandwidth. The higher stress limit could also eliminate the necessity of the stress rod, simplifying fabrication and cost. TRS and Penn State ARL will design and fabricate a composite PMN-PT single crystal, and test it under both low and high field conditions.

Title:Broadband Volume Search Sonar for Towed Mine Hunting Devices
Abstract:TRS Technologies, Inc. and Raytheon propose to develop broadband, low voltage sonar projector elements for mine hunting systems using relaxor ferroelectric single crystals. Specifically, we will develop crystal tonpilz elements for the side-scan, volume search sonar array on the AN/AQS-20 towed mine hunting system. These elements will be designed to have crystal drive sections with high aspect ratio by using very stiff carbide head masses thus resulting in coupling coefficient and bandwidth near the theoretical maximum. We will also exploit the very high mechanical strength of zero surface defect crystals to fabricate minimally prestressed transducer elements for improved stability, reduced loss, and reduced weight. The primary goals of the program will be to use crystals to reduce the AN/AQS-20 side scan volume search sonar driving voltage by a factor of 2 and to increase the sonar's bandwidth to > 100%. In the Phase II program TRS and Raytheon will develop a full scale volume search array for the AN/AQS-20. Ultimately single crystal piezoelectrics are expected to enable greatly expanded search ranges, mission times, and mine classification abilities for a broad range of Navy mine hunting systems without increasing and perhaps even decreasing system cost.

Title:Piezoelectric Single Crystal Stacks for Improved Fuel Injector Performance
Abstract:Engine performance and fuel consumption in the Navy's surface ships, submersibles, and aircraft are a significant concern from both an operations and logistics viewpoint. Higher fuel efficiency leads to longer times between resupply or lower operating costs, while increased performance is always desired during combat operations. We propose the use of single crystal piezoelectric materials to enhance the performance of a critical aspect of combustion engine technology, the electronic fuel injector, to improve both performance and efficiency. By replacing the existing piezoceramic driving technology with piezoelectric single crystals we will improve the three critical requirements for fuel injector actuators: stroke, force output, and bandwidth. This can be achieved in a component of identical size, or smaller than, existing driving stacks, and may allow for the omission of displacement amplification systems resulting in smaller, less expensive fuel injectors. The higher performance of the fuel injectors will allow for more precise control of engine performance, allowing the Navy to choose between higher power, greater fuel efficiency, or lower emissions from their engines.

Title:Secure Embedded Software Radio (SESR)
Abstract:Coherent Logix, Incorporated (CLX) proposes the Secure Embedded Software Radio (SESR) program to facilitate the development of a SDR development kit based on the Hyper64 processor with an accompanying software development flow to support rapid development and fielding of this technology to the Warfighter. The HyperX Technology is viewed by JPEO JTRS HMS as a risk reduction technology that is slated for insertion into the JTRS HMS SDR program of record upon successful demonstration. It will simultaneously enable order of magnitude improvement in power savings while reducing chipset count, thus size and weight of the radio. The HyperX processor technology is fully programmable and reconfigurable on the fly and is supported by industry standards based [hardware agnostic software development flow and] programming model using ANSI-C and MPI (message passing interface) API. This provides reduced life-cycle costs and future proofing of hardware through fully portable software code. The Hyper64, first in a family of HyperX based chip products, will be available COTS in the second quarter of 2007. This effort capitalizes on the investments made by DARPA; U.S. Army ARDEC and ARL; AFRL Sensors, Space Vehicles Directorate, and Information Directorate; and JPEO/PM JTRS HMS under the DARPA ECHiPPS Program.

Title:Embeddable Software Programmable Radio
Abstract:The goal of this project is to produce a chipset, composed of commercially available components, which can take advantage of the JTRS software communications architecture (SCA) and software waveform library. Because of the need for this device to operate at both unclassified and SECRET classification levels on a single processor, with a single operating system, a major focus of this effort will be to devise verifiable partitioning methods to prevent intermingling of differently classified information. NAVSYS has proposed a design for a Mini-SDR that uses COTS components and a partitioned design to significantly reduce the numbers of component needed to perform the red, black and crypto processing required for running a JTRS waveform. Under Phase I we propose to develop the Mini-SDR design and work with NSA to evaluate the security architecture against the Uniform Infosec Criteria. The Phase I design will result in a proposed Phase II effort to build a compact software programmable military radio chipset that is capable of being embedded in unitary computing, display and position location devices envisioned for future Marine Corps ground forces. We will provide supporting material for the design to predict the size, weight, cost and power of this embedded SDR solution.

Title:Embeddable Software Programmable Radio
Abstract:The Navy needs a compact, software-programmable military radio developed that is capable of being embedded in unitary computing, display, and position location devices envisioned for future Marine Corps ground forces; taking into account classified and unclassified information handling within the embedded radio and within the framework of the Joint Tactical Radio System (JTRS) software communications architecture. To reduce the size, weight, power, and cost of software-programmable radios and to provide enhanced security for the Navy and Marine Corps, Williams-Pyro, Inc. proposes to develop the Embeddable, Miniature, Programmable, Robust, and Secure or EMPRS radio-a software-programmable military radio with efficient security architecture that takes advantage of the JTRS SCA software waveform library and prior development. EMPRS supports multiple waveforms through software reconfiguration/programming; uses a single processor to handle both classified and unclassified data; and interfaces with RF front-end(s) operating from 2 MHz to 2 GHz. The EMPRS radio integrates the elements of a software-programmable radio in a single System-on-a-Chip (SoC) package for optimum miniaturization. Our solution also meets the need for operating future small unit devices at both unclassified and classified levels on a single processor with a single Operating System (OS).

Title:Incorporating Affective Stressors in Virtual Training Environments
Abstract:Virtual environment (VE) technology is one training method designed to promote effective information transfer to the real world. The goal of many VE trainers is improved cognitive and/or psychomotor performance. While both cognitive and psychomotor behaviors are important to task learning and performance, Bloom identified an additional behavior in his Taxonomy of Learning: affective behaviors. The study and understanding of affect in any VE training system is important to optimize learning and training transfer. Past work suggests that incorporating affect in VEs is challenging, as affective responses are not always experienced in VEs regardless of visual fidelity and large individual differences in affective responses have been reported. To address current limitations in creating an affectively appropriate VE training system, this proposal outlines development of the Affective Virtual Environment Training System (A-VETS) framework for introducing affect into VE training systems. A-VETS includes an architecture for determining trainee context, instructional context, desired approaches for creating immersion, and a set of strategies for aligning these contexts into one cohesive training environment designed to optimize learning and training transfer. By identifying how affective cues impact learning, designers can incorporate appropriate affective cues into training VEs to increase the effectiveness of VE training, particularly for high stress military environments.

Title:A Framework for Incorporating Affective Learning in Virtual Training Environments
Abstract:The effectiveness of current Virtual Environment training systems can be greatly enhanced by integrating affective components into those systems. In the proposed effort, a theoretical model that we developed for utilizing auditory feedback to modify the user's affective state will be expanded upon to include visual and haptic modalities. This will provide a foundation for incorporating affective components into training systems. Next a pragmatic analysis of existing affective state assessment approaches will be carried out in order to select approaches that are suitable for use in deployable systems. Current systems do not encode training instructional context so, in effect, they operate without a lesson plan. As part of this effort we will devise a scheme for encoding instructional context so that training outcomes as well as expected affective states for each state of learning can be specified in training systems. Finally, a specification will be developed for a prototype system that capitalizes on an existing training simulation framework that we have been developing for a number of years and is currently used in deployed and commercial systems. This approach will minimize risk and development time and will greatly enhance the commercialization potential of this technology.

Title:An Expendable, Multi-Spectral, Surfzone, Optical Measurements System
Abstract:Aret Associates' is proposing to develop a hyper-spectral, IOP sensor system that can be deployed by a variety of means in the surfzones of forward areas. It will measure, record and report IOPs that are vital to naval MCM operations. The sensor system will be inexpensive enough to be expendable, but survivable enough to be deployed for a period of up to a few days without failure. Communications between sensors and their base station will be via satellite link. Sensor locations in moored or UUV-borne applications will be determined by outfitting the communications modules with GPS. If deployed on a drifting body the sensor will continuously report its data. Our method is to develop a compact IOP sensor designed around the novel concept of a hyper-spectral modulation transfer radiometer. This instrument will measure the modulation transfer function (MTF) through a volume of water. The modulation transfer function (MTF) is a measure of how light is scattered and absorbed while propagating through an optical system. The scattering and attenuation coefficients will be directly calculated from the MTF data. Hyper-spectral backscatter and source normalization data will also be collected.

Title:Surfzone Water Properties Sensor
Abstract:The objective of the proposed work is to design, fabricate and test inexpensive (nominally expendable) water property measurement systems (SWANs) to provide environmental optical parameters in the surfzone that are critical for MCM operations. Work will build on recent technological advances, including recent development of attenuation, scattering, and backscattering sensors for AUVs and other compact platforms. A SWAN (Surfzone Water Attenuation Node) will have a newly designed sensor (the BAM3) measuring multi-spectral attenuation, c, at 470, 532, and 660 nm, as well as GPS and RF communications. SWANs will be able to operate as drifters or as moored packages and will be capable of intelligent networking. A goal is to achieve a cost factor of $1K for the BAM3 and $2K for the SWAN. A SWAN-x version will also be developed that will additionally have recently developed sensors measuring total scattering (AUV-B) and multi-wavelength backscattering (ECO-BB3), thus providing the IOPs attenuation, scattering, absorption, and backscattering.

Title:SENTRY : IED COUNTERMEASURE SIMULATION & PREDICTION TOOL
Abstract:According to the Iraq Study Group, US Forces must continue to support Iraq to prevent the government from falling and being influenced by neighboring countries (Syria and Iran) and to prevent a propaganda coupe for Al Qaeda and the spread of radical Islam. Our soldiers, marines, and sailors are regularly subject to IED attacks by Shi'a militia, Sunni insurgents, and Al Qaeda. Improvised explosive devices (IED) are the weapon of choice for such adversaries, because they require a relatively small investment in proportion to their lethality. As each successive generation of device increases in lethality, as techniques for emplacements evolve, and as organizational and financial structures for IED attacks harden, prevention of IED attacks requires increasingly sophisticated U.S. countermeasures, To meet this need, 21st Century Technologies (21CT) proposes SENTRY, an application for modeling, simulation, and counter-measure strategy generation to target and disrupt asymmetric threat networks that plan and execute IED attacks.

Title:PICASA: Predictive IED Combinatorial Analysis and Simulation of Adversaries
Abstract:Attacks using Improvised Explosive Devices (IEDs) are the leading cause of U.S. combat deaths and injuries in Iraq. Despite our efforts, the enemy has proven adaptable to our tactics, techniques, and procedures to stop, negate, or minimize the damage of the blast. To overcome this problem we must move up higher in the kill chain and disrupt these terrorist cells at their source. The Decisive Analytics Corporation (DAC) Team proposes an approach termed Predictive IED Combinatorial Analysis and Simulation of Adversaries (PICASA). The PICASA approach starts at the cultural and sociological level by developing models of terrorism activity through the guidance of terrorism expert Dr. Marc Sageman. DAC's advanced data mining, social networking, and predictive analysis tools use these models to then move higher up the kill chain. PICASA provides the capability to ingest disparate data sources of intelligence data (including IED activity), identify key actors and organizations, and predict and evaluate possible coalitions of social networks. Our advanced algorithms developed under this effort will be immediately tested on live data from the theater through DAC's Agent-based Intelligence Services (AIS) - a tool that is in the hands of the Warfighter and is performing predictive analysis on Iraq data today.

Title:Detecting Enemy Forces United to Strike with Explosives (DEFUSE)
Abstract:Soar Technology proposes to develop the Detecting Enemy Forces United to Strike with Explosives (DEFUSE) system to help address the constantly evolving IED threat at points before the IED blast. DEFUSE leverages the DARPA RAID Adversarial Reasoning Module (ARM) technology, which has been tested successfully in DARPA gate experiments over the past 2 years and is currently going through transition evaluation processes via the Joint IED Defeat Office (JIEDDO). The ARM predicts the locations, frequency, and types of IEDs (and more) based on a combination of symbolic tactical reasoning, probabilistic Bayesian reasoning, and a swarming simulation that considers many thousands of possible interactions and futures, including those involving US force activity. We propose to add to the ARM a dynamic network analysis layer (DNAL) to model activities and relationships earlier in the IED lifecycle than placement and explosion. The DEFUSE output will be a unique view of the battlefield that combines strategic and tactical views predicting (1) possible IED attacks, (2) what technologies and tactics will be employed by which factions over time, and (3) how faction structure and relationships will change due to changing technologies.

Title:Lightweight and Compact Transient Electric Power Response Enhancement Concept
Abstract:Airborne electric power needs are becoming substantial, versus airframe propulsion power. Also, these electric power needs are applied in very short timescales that are not compatible with conventional gas turbine engine response capabilities. For these cases, the engine output and electric power quality are both degraded. A compact and lightweight means of improving the engine response to these transients is needed. Altex has identified a compact and lightweight engine modification that can address engine transient loads that are applied in less than 0.1 seconds. The approach is general and can apply to both military and civilian gas turbine engines. Preliminary analysis shows that the concept has potential. Under the proposed effort, the concept will be incorporated into a time dependent engine model, to assess performance of the concept under Navy specified load transients. In addition, brief tests of a key concept component will be carried out to support feasibility. Lastly, the performance and cost benefits of the concept will be quantified, and the advantages of the concept over alternatives will be determined.

Title:Transient Electrical Power Response Enhancement for Turbine Driven Generators
Abstract:Airborne electrical power requirements are increasing significantly to support Intelligence, Surveillance, and Reconnaissance (ISR) sensors, electronic attack suites, and directed energy weapons for military applications. When the electric generator is directly coupled to the propulsion engine, relatively large electric torque transients are often introduced with dynamics faster than previously handled by the engine control system. These transients may have serious implications with regard to stall margins, mechanical stress, speed regulation, and available thrust. To address challenges posed by such transients, PCKA will partner with Rolls-Royce Corporation (RRC) to develop novel architectures and system control strategies to maximize transient turbine engine performance of a high mach missile system. In the proposed Phase I effort, PCKA will collaborate with ONR, AFRL, and RRC to define such architectures along with representative operational profiles. PCKA will create dynamic system models to simulate and analyze the resulting architectures. Simulation results will be used to optimize system controls to maximize transient performance capabilities of the turbine engine. If successful, Phase II efforts will refine MS&A results and support a hardware demonstration of the most promising approaches. If successful, developed technologies will ultimately transition to DoD programs under a Phase III contract.

Title:Energetic Secondary Fuel Injection for Propulsion System Performance Improvement
Abstract:This program will develop the technology needed to design active combustion control (ACC) techniques using energetic secondary fuel injection concepts. We will use the ACC experiments of Yu (UMD) and the energetic fuel research of Yetter (PSU) as stepping-stones. CRAFT Tech will assess and validate their hybrid RANS/LES methodology (previously used to design active control systems for weapons bays with microjet actuation) using datasets of Yu. Initial work will focus on analyzing a rearward facing step dump combustor with secondary nano-Al injection. The CFD code to be used has a detailed nano-Al combustion model based on collaborative work with Yetter for secondary nano-Al injection into scramjet combustors. Pulsed injection modeling work will make use of Yu's data for an axisymmetric ramjet combustor with a pulsed fuel injection system. Yu and Yetter will serve as consultants on this effort. Yu will formulate a Phase II test plan based on use of existing hardware to evaluate improved ACC concepts, and, to directly support the validation of a CFD code configured to directly support ACC concept design. Yetter will examine the applicability of several energetic fuels that show promise for secondary injection for ACC applications, to be tested in Phase II.

Title:Pulsed Injection of Enhanced Energetic Fuels for Performance Optimization
Abstract:Combustion instability can adversely affect propulsion system performance, generate noise and vibration, and shorten hardware life. Its control represents an ongoing challenge in combustion system design. EERGC Corporation, in cooperation with subcontractors Energy Research Consultants (ERC), and Northrop Grumman (NG), proposes to reduce combustion instability and enhance performance of chemical propulsion systems by controlled pulsed injection of a gelled liquid secondary fuel loaded with energetic solids. The fuel will be delivered into a combustor via pulsed injection at quantities sufficient to assert control authority, and the pulsing will be optimized with respect to the phase and frequency of natural combustor oscillations to minimize their amplitude and/or enhance combustor performance. This work builds upon prior EERGC work in intelligent pulsed combustion control; by EERGC in collaboration with NG, developing gelled fuel formulations loaded with energetic solids. It represents an innovative fusion of these different technical endeavors and forwards the state of the art in both. The Phase I program will provide proof-of-concept by developing a suitable stable energetic gelled fuel, showing that it can be atomized without clogging the injectors and can be reliably and controllably pulsed, and providing a laboratory demonstration that fuel pulsing can affect combustion instability.

Title:Low-Cost, Highly Efficient, Digitally Beam Formed, X-Band Transmit ESA for Radar (9735)
Abstract:Hittite proposes to develop a low-cost, digitally programmable waveform distribution and beamforming architecture for transmit electronically scanned arrays (ESAs). A four-element Digital Sub-Array (DSA) will serve has the basic building block to construct large (1,000 to 10,000+ element) arrays. High efficiency will be achieved using switched-mode power amplifier (PA) techniques. Digital transmit data will be distributed and true-time-delayed directly at the X-band (nominally 10 GHz) transmit frequency, eliminating the need for upconversion, minimizing part count, power consumption, and cost. Each element will radiate 3.2 W with a PA power-added efficiency of 70%. Notionally, 16 DSAs (64 elements) will be assembled to form a Tile, and 16 Tiles (1,024 elements) will be assembled into Panels. Large ESAs will be assembled from one or more Panels. For illustrative purposes, a single-Panel ESA (1,024 elements) would radiate nearly 3.3 kW (70.2 dBW EIRP) with a 3.17X beamwidth. A nine-panel square ESA (9,216 elements) would radiate 29.5 kW (89.3 dBW EIRP) with a 1.06X beamwidth. The DSA will enable scan angles up to ,b70,a. With the exception of the GaN PA, all active circuitry will be realized in IBM's 8HP SiGe BiCMOS process via DoD's ITAR-compliant, Trusted Foundry contract. The Phase I effort will result in the preliminary design of a Digital Sub-Array (DSA) with which to build X-band ESAs for radar. Critical technology will be developed and demonstrated in Phase II leading to the complete antenna system development in Phase III. In a complementary effort, true-time-delay, digital beamforming receive circuitry can be developed directly at X-Band to provide a complete transmit/receive DSA.

Title:A Novel Reconfigurable Distributed Anomaly Detection Framework
Abstract:Intelligent Automation, Inc. (IAI) proposes to develop a novel, distributed framework for the detection of faults and anomalies. The proposed framework is based on dynamic, reconfigurable agents and is capable of automatically representing and managing disparate data sources. Meanwhile, efficient processing requires automatic selection and extraction of features from different data sources for fault or anomaly detection. In our approach, advanced feature-selection techniques are employed to enhance the anomaly detection performance. Finally, since there are many techniques for fault or anomaly detection and each has different data requirements and a different chance of success, including physical model-based methods, rule-based methods, and data-driven methods, we know that these methods need to be integrated. Our distributed approach is open and flexible to accommodate any of these methods as agents, and a decision level fusion technique is proposed for pooling/aggregating detection decisions made by these detection agents. A promising information fusion method called transferable belief model (TBM) is proposed as the core fusion technology in this proposal to achieve more reliable and accurate fault/anomaly detection.

Title:Dynamically Reconfigurable Data Architectures for Aircraft Data Analysis and Anomaly Detection
Abstract:In the field of aircraft health management, the integration and availability of historical data from multiple data sources is necessary for diagnostic and prognostic algorithms to realize their full potential. Especially important is the integration of historical in-flight operational data with ground-based maintenance data. Effectively integrating these data sources is difficult because key ground based maintenance fields are commonly entered in the form of natural language text rather than in a controlled vocabulary. Furthermore, with the ever increasing number of in-flight parameters available, selection of informative parameters for data mining is a time consuming, iterative process that requires domain knowledge. To address these difficulties in developing aircraft health management algorithms, Referentia Systems, Inc proposes to develop interactive software tools to mitigate these challenges. One software tool will perform information extraction from maintenance logs using a customized vocabulary. The structured results will then be integrated into a larger data warehouse. The second tool will enable interactive GUI-based development and execution of preprocessing and data mining algorithms for in-flight data. Results from each of these tools will be integrated into an existing dynamically reconfigurable health management data warehouse.

Title:Automatic scene understanding and generation of textual descriptions
Abstract:We address an important yet challenging image processing problem: automatic scene understanding and generating textual description. Answers to the following two questions would be needed to provide a good semantic description of a scene: (i) What objects are present in the scene? (ii) Where are they located in the scene with respect to each other? The answer to what is defined by nouns in a language, and where is defined by prepositions. We present a novel semi-automated method to provide labels to the image regions, thus providing answers to what. This approach uses low-level visual features and clustering techniques to assist a human in quickly training a labeling system. Note that this is an offline system; no human intervention would be required at the time of actual operation of the system. In order to define where the objects are with respect to each other, we plan to create grammar rules for the particular prepositions of interest, which would establish context-based relationship between regions of the image. The region attributes and their relationships are then used to make higher level semantic interpretations about the scene followed by generating textual descriptions.

Title:Context-sensitive Content Extraction and Scene Understanding
Abstract:Over the last few decades, progress toward automatic video understanding was almost exclusively due to improvements in bottom-up image and video analysis. As was the case with the initial top-down approaches, pure bottom-up approaches have run into fundamental limits. This proposal expands on recent advances in top-down/bottom-up information fusion to exploit syntactic and semantic information inherent in both approaches. Bottom-up information describes scene elements, moving objects and their interactions. Top-down information encapsulates object- and domain-specific information. Top-down information will be represented using stochastic attribute grammars. Grammars, studied mostly in language, are known for their expressive power. Transferring the idea of a grammar from language to vision, ObjectVideo proposes to define a visual vocabulary from pixels, primitives, parts, objects and scenes, and also specify their spatio-temporal or compositional relations. A stochastic bottom-up/top-down inference strategy will use this representation for efficient and accurate content extraction. The detailed representation will be used to automatically annotate imagery specifying its content and context. At the completion of Phase I, ObjectVideo will demonstrate a proof of concept system for syntactic, semantic and conceptual content extraction from maritime and urban imagery.

Title:Embedded Metal Nanoparticles for Efficient Thermoelectric Power Generation
Abstract:Aerius Photonics proposes to demonstrate the feasibility of high output power thick film generator modules using nanoparticle-embedded materials that are amenable to production using bulk crystal-growth methods. These nanoparticles provide benefits similar to superlattices, such as increasing the Seebeck coefficient and decreasing the thermal conductivity, but with the major advantage being that they are transferrable to bulk crystal growth. Aerius Photonics proposes to make thermoelectric power generators using hybrid elements of two materials, one of which is the nanoparticle embedded material and the other being a conventional thermoelectric material, Bi2Te3 . The combination of the two materials provides the superior performance at room temperature of Bi2Te3 with the superior performance at high temperature of the nanoparticle embedded material. Using bulk materials allows the stack to take full advantage of the temperature drop across the module and combine to make a cost-effective, high efficiency module.

Title:High-Efficiency Thermoelectric Generator
Abstract:There have been several reports [1, 2, 3] of enhanced ZT at various temperature regimes using superlattice, quantum-dots, and nano-crystalline inclusions, respectively. In combination with semiconductor technology tools for device fabrication, these materials offer unprecedented advantages such as high cooling power density and high-speed cooling/heating in thermal management and high specific power in direct thermal-to-electric power conversion systems. In particular, the thin-film superlattice structures in the p-type Bi2Te3 / Sb2Te3 system has indicated a figure of merit (ZT) of 2.4 near 300K at RTI [1]. While these Bi2Te3-based superlattices are useable in power conversion applications, using small temperature differentials between 300K to 450K, PbTe-based materials are likely to offer a more attractive band gap for power conversion up to 700K as outlined in the announcement N07-086. Thus the development of PbTe-based superlattice would enable the availability of nanoscale materials in the temperature range of 300K to 700K. While PbTe-based quantum-dot superlattice grown by MBE has shown potential ZT of 1.6 at 300K [2] and as high as 3 at higher temperature, it would be advantageous for a lower cost growth method to be employed that would also enable thicker films on the order of 100Ym. Nextreme Thermal Solutions, Inc. along with RTI International has developed a simple evaporation method for depositing superlattice films consisting of PbTe and PbTe0.75Se0.25 layers [4]. However, consistently growing thick films on the order of 100Ym that maintained the ZT enhancing nanostructure would be a daunting task. An alternative method to reach these thicknesses that could adjoin films together to form a larger bulk material needs to be developed. The use of a compaction process to take thin-film materials and obtain nano-structured bulk materials is proposed.

Title:Cultural Agent Model to Predict in Habitant Opinion Reactions (CAMPHOR)
Abstract:One of the strategic goals for the United States armed forces is to win over the hearts and minds of the population in a military theater of operations. Special Operations Forces (SOF) perform missions in part to help win this battle for hearts and minds. In order to be more effective in attaining this goal, SOF team leaders need easy and rapid access to accurate, timely, and detailed intelligence about the effect of mission actions on the opinions of the local population. Aptima will improve the ability of intelligence officers to support SOF team leaders by providing an accurate and robust computer simulation of cultural dynamics that estimates the effect of SOF actions on local opinion. Social identity theory, theories from cognitive and social psychology, and theories related to social network analysis will inform the structure of the model. A data architecture will help users to populate the model even without complete, high-quality data. Experimentation and sensitivity testing will allow users to gain accurate insights when there is uncertainty in the data. With both model and data architecture, intelligence officers will be able to efficiently and effectively support SOF operations in pre-deployment, during mission planning, and in the field.

Title:Computational Models for Effects-based Operations in Special Forces Teams: Tool for Effects-based Allocation Modeling (TEAM)
Abstract:Pacific Science & Engineering Group (PSE) proposes the Tool for Effects-Based Allocation Modeling (TEAM) to address the gap in determining the impact of unit assignment on task outcome effects. The goal of this system is to inform planners on how to shape the operational courses of action (COAs) through unit assignment to better meet the mission objectives. TEAM will follow a two-step process to assign units to mission tasks and to assess the effect in the operational environment. The first step in the process will perform task-unit allocation based on an extended attribute set; not only the capability requirements of the task, but also attributes that characterize different outcomes of how the task is performed and perceived. The second step in the process will provide effects-based feedback to the COA development based on projected impacts of different unit assignments; the model will predict whether these parameters produce significant changes in performance in the operational environment and how these changes are predicted to be perceived by a local observer. The system links the characteristics of the assigned unit to the outcome effects of the operational tasks and will allow iteration between the two modules to complete effects-based planning.

Title:Propulsor Blade Advanced Composite Materials
Abstract:The U.S. Navy has significant interest in the development of composite materials which substantially improve the performance of composite propulsor blades. Improvements in erosion resistance (e.g., cavitation, rain, and sand) and impact durability are of particular interest. These improvements must be enabled without degrading other performance characteristics including vibration damping and mechanical properties. Furthermore, these performance improvements must come at a reduced cost including acquisition, fabrication, and maintenance. Composite Technology Development (CTD) proposes a multidisciplinary approach to develop and qualify new classes of composite materials for propulsor blades which possess significant erosion resistant and impact durable characteristics. These materials will be based on new and existing chemistries which have demonstrated significant promise in achieving the program's goals. CTD will work with key industry partners to demonstrate the material's applicability to propulsor blades by adopting an iterative design approach to be performed in tandem with the material development and evaluation efforts to produce a propulsor design incorporating the developed technology, which demonstrates significant performance improvements over existing propulsor blades.

Title:Low Cost, Impact Damage Resistant Polyurethane Matrix Blades
Abstract:KaZaK Composites proposes to design and demonstrate low cost composite blades made with materials and processing technology already proven to resist impact, erosion and cavitation damage in Navy applications. While technology to be demonstrated by KaZaK will be generically applicable to all types of blades and propulsors, we propose to focus our initial investigation on the Lift Fan Paddles of the LCAC. These paddles, currently extruded aluminum, are subjected to extreme impact and sand abrasion conditions during operations, and represent a costly maintenance item for the Navy. KaZaK's proposed solution includes 1) Use of high strain-to-failure polyurethane as a matrix material, 2) Use of a macro-composite design to achieve an otherwise unobtainable combination of structural stiffness and damage resistance, and 3) Design for fabrication by cost-effective manufacturing methods such as pultrusion and VARTM to assure acquisition cost affordability. KaZaK has previously demonstrated the effectiveness of the proposed material, configuration and manufacturing technology combination in several Navy-sponsored programs, and currently has products based on the same technology on active CVN sea trails. Phase I will include design, sample fabrication and testing of full scale LCAC lift fan blade prototypes to validate the mechanical, impact and abrasion resistance properties of candidate designs.

Title:CoVE: Collaborative Visualization Environment
Abstract:Current and future operational environments are likely to be characterized by a range of missions in a variety of locations around the world. For all these operational environments there is a large volume of data collected via sensors, human input, simulations and models that need to be analyzed to support effective decision-making. However, the problem with all of this data is information overload. Hence, military decision makers need to be able to abstract data to amplify cognition via information visualization. This research will design and build new collaborative visualization tools and techniques to support real-time decision making for large datasets with different quality, pedigree, redundancy and uncertainty levels. The Collaborative Visualization Environment- CoVE - will be based on team collaboration theory, combined with an organizational model, to provide a wide variety of interactive chats, graphs and dashboards supported by innovative information sharing technology.

Title:A System for Enabling Distributed Visualization and Collaboration (EDVAC)
Abstract:Modern military operations rely on the ability of intelligence personnel to manage large volumes of dynamic information from heterogeneous sources. The intelligence process is necessarily a cooperative effort, and collaborative reasoning about that data and its visual representations must be efficient across display systems. One promising approach to improving the design of collaborative display systems is to exploit how operators use and share qualifiers of information, or meta-information. We propose to design and demonstrate a system for Enabling Distributed Visualization and Collaboration (EDVAC). Three core components characterize our approach. First, we will perform a cognitive task analysis on a specific scenario to develop a structured categorization of sources and types of information and meta-information, and identify difficulties in collaboration within modern DoD systems. Second, we will develop a system to augment incoming data with meta-information, create user-customized meta-information visualizations on collaborative displays, and provide analysts with interfaces to share meta-information visualizations. Third, we will design a methodology to assess the effectiveness of these techniques. We will leverage our team's expertise in the development of computer supported cooperative work (CSCW) systems and complex display systems to rapidly design the proposed system and develop novel collaborative visualization techniques.

Title:A CommonSense Information Visualization for Distributed Collaborative Environments
Abstract:Collaborative, analytic visualization has great potential for analyzing and integrating large, multi-source data sets, and enabling the joint application of expertise. Previous developments have focused on supporting technologies and methods such as novel displays, network architectures, and data processing schemes. As the literature points out, adoption of a systems approach that incorporates theories of reasoning, sense-making, cognition, and perception and examines other human systems integration impacts, such as the training required by visual analysts, is required to unlock the promised potential and achieve true collaboration. We will develop a prototype environment, "CommonSense," based on these theories, that supports distributed, collaborative, visually based work. CommonSense will be comprised of a shared visualization environment integrated with a suite of communication tools. Additionally, we will examine the supporting technologies and methods through the lens of user need. By doing so, the user becomes a much-needed integrating element to work being conducted in the field. The prototype environment, together with user-centered technology studies, will enable us to demonstrate the feasibility of an extensible, comprehensive systems methodology for development of other such environments.

Title:Risk and Uncertainty Management for Multidisciplinary System Design and Optimization
Abstract:Computational methods and simulation based methodologies can be combined for optimizing the design of undersea weapons with respect to cost and performance. Multiple engineering disciplines such as: warhead performance, structural-acoustics, sonar performance, guidance and control, electromagnetic and thermal analyses of the electric motor, computational fluid dynamics, and structural dynamics must be considered during undersea weapon design. Therefore an organized multi-disciplinary optimization (MDO) strategy must be employed for the design. Due to the large number of iterations required during a MDO process and in an effort to include high fidelity simulations in a MDO process, theories for developing metamodels have been established. In any optimal design the final system operates close to several of the constraints since the optimal point is driven against the active constraints by the optimization strategy. Deterministic optimization methods do not account for variability introduced due to manufacturing, material properties, and equipment performance, nor for uncertainties in the mission profile, human operators, the environment, and the simulation models themselves. The proposing firm (MES) will develop a network of probabilistic metamodels and incorporate them in a multi-disciplinary design optimization environment. The new developments will be demonstrated through a case study relevant to undersea weapon design. Existing MES products in MDO under uncertainty, and in time dependent metamodeling, will comprise the foundation of the proposed research, thus maximizing the impact of the sponsor's funding.

Title:Risk and Uncertainty Management for Multidisciplinary System Design and Optimization
Abstract:Phoenix Integration proposes to develop a preliminary software framework for assessing and managing risk and uncertainty in engineering system design. If uncertainties can be taken into account and properly managed during the design process, the resulting systems will be safer, more reliable, and more robust. In this project, Phoenix Integration will work with the Applied Research Laboratory at Penn State University to demonstrate the technical and commercial feasibility of a new uncertainty management methodology. This methodology utilizes Monte Carlo simulation to assess the uncertainty of the system. A key element in the methodology is the use of metamodels to reduce the computational expense of the Monte Carlo analysis. The preliminary uncertainty management framework will feature an easy to use interface that will allow designers to build and execute subsystem and system simulation models. Using the graphical interface, users will be able to create and validate metamodels for any of the subsystem components. Designers will then be able to assign uncertainties to any of the system or subsystem inputs and perform a Monte Carlo simulation and sensitivity analysis of the system. Visualization and post-processing tools will allow designers to understand the results in real time and to interactively make design choices.

Title:A Universal Tactical Cryocooler Drive
Abstract:Superconducting MicroElectronic (SME) systems are becoming commonplace due to their substantial benefits in performance and cost when compared to traditional, semiconductor-based components. To achieve widespread adoption of SME systems, low-cost and rugged cryocoolers are needed. This need also includes universal drives which can be applied rapidly with minimal cost and technical risk. Creare proposes to develop a universal Tactical Cryocooler Drive (TCD). We will adapt our previously developed cryocooler and sensorless vacuum pump drives to minimize technical risk and accelerate development. Our TCD will provide dual, independent drives, which can be customized for each application with only software changes. We will continue our close collaboration with a well-respected provider of military electronic components to provide a small, vibration hardened, and low-cost package. In Phase I, we will demonstrate feasibility with a comprehensive design study and prototype demonstration. We will also establish performance metrics that can be used to evaluate feasibility during Phase II. During Phase II, we will produce a prototype with the form, fit, and function of the final product and demonstrate operation with environmental and vibration performance testing with a typical tactical cryocooler.

Title:Miniaturized, Efficient, Vibration Hardened Drive and Control Electronics For Compressors
Abstract:Compact compressors have recently undergone remarkable progress in long life, mechanical efficiency, and vibration tolerance. Their control electronics require further improvement to match that progress. HYPRES, in collaboration with Lockheed Martin (LM), is developing a 4.5K 4-stage pulse tube cryocooler to be integrated with superconducting electronics for communications applications. We propose to develop a novel set of drive electronics with dual outputs and on-board calibration tools to continuously optimize the operation of the cryocooler. The electronics will be designed to work efficiently with the aforementioned pulse tube cryocooler expected to be operational at HYPRES by early 2007. The design will ensure that vibration is minimized and the power efficiency is significantly enhanced. Options such as switching power amplifiers possessing close to 100% efficiency, and drive technology such as Pulse Width Modulation (PWM) will be considered during the Phase I project whose goal is a complete circuit architecture for the drive electronics as well as sensor and control circuitry for optimum operation of compressors. We will collaborate closely with LM and utilize their expertise in this effort. Phase II will produce a complete prototype ready for commercial manufacture.

Title:Littoral Environment Visualization Tool
Abstract:The U.S. Navy would benefit greatly from a tool that could produce realistic scenes of the littoral environment based upon standard meteorological and oceanographic inputs in near real time; simulate a wide range of sensors aboard platforms above, below, or on the ocean surface; and allow the user to manipulate environmental inputs and immediately view their effects on the scene. The goal of this SBIR program is to develop a Littoral Environment Visualization Tool (LEVT) that provides all these capabilities. Arete's state-of-the-art software tools, already in widespread use across the film, video gaming, and advertising industries as well as in military applications, are capable of generating open ocean scenes of breathtaking realism. In this SBIR program, Arete will extend these capabilities to the littoral environment by simulating phenomena such as wave breaking and nonlinear wave propagation. These inherently nonlinear effects are difficult to compute in a near real time application. Arete is prepared to meet this challenge using an approach that balances the requirements for visual realism, interactivity, and near real time results.

Title:Littoral Environment Visualization Tool
Abstract:A tool does not currently exist that allows an individual to visualize the littoral environment or changes to that environment with a fair degree of realism and on a near real-time basis. Sonalysts, Inc. wants to improve upon this situation by applying gaming expertise to develop a simulation tool that addresses these issues. The tool we propose will make use of Sonalysts' state-of-the-art commercial simulation technology. This technology will be applied to provide computations, graphics, video capture, and simulation for the environmental elements within the littoral zone. We will demonstrate an ability to simulate environmental changes and observe their effect on a near real-time basis in such elements as wind speed and direction or in wave height, period, or direction. We will illustrate the capability to modify these environmental elements by interactions between the user and the simulation tool through easy-to-use graphical user interfaces. Our Phase I approach will address three key technical objectives: 1) Obtain information to provide an understanding of the computational effort required for varying degrees of visualization detail and realism, 2) Evaluate forecast model data to determine sufficiency for providing realistic animations, and 3) Determine ability of animation to realistically reflect changes to the littoral environment.

Title:RF Guidance Sensor Windows for High-Speed and Hypersonic Air Vehicles
Abstract:Advanced Cerametrics, Inc (ACI) has developed a technology to make nearly any ceramic into flexible fiber. ACI has also developed a material that meets the needs of hypersonic missile radomes (barium alumino silicate-BAS). ACI has developed a method to make the BAS into fiber form and to produce fibrous monoliths of BAS where the BAS fibers reinforce a similar BAS matrix. These components have a low dielectric constant suitable for radome RF requirements. The BAS materials, especially in fiber monolith form, have a very good CTE with high temperature capability above 2700 F. The fibrous monoliths can be back filled with an aluminum phosphate slurry to form a graded structure sandwich to improve the density and toughness to resist rain erosion and mechancial stresses. The work in this SBIR will continue ACI's work begun on the BAS to make functioning hypersonic missile radomes by the end of Phase II.

Title:Ceramic Composite Windows and Radomes for Hypersonic Vehicles
Abstract:Conventional dielectric materials for hypersonic radome and window applications exhibit a number of performance limitations including inadequate thermal shock resistance, variations in electrical (dielectric constant and loss) and structural performance (mechanical strength) with temperature, and difficulty in fabrication to the desired shape. We propose to develop high strength, high toughness, high temperature stable, low dielectric constant continuous fiber-reinforced ceramic composites with wide band-pass in the L band (1-2 GHz) for GPS navigation and guidance, S-Ku (2-18 GHz) band for wrap-around antenna, and W band (94 GHz) for terminal homing for hypersonic window and radome applications. The Phase I program will fabricate a fiber-reinforced ceramic composite with the required electrical and mechanical properties for hypersonic windows and radomes. Equibiaxial flexural strength and thermal shock resistance of the composite disks will be measured up to 1500C, and Weibull parameters will be calculated to determine their reliability. Free-space microwave dielectric properties, dielectric constant and loss tangent, between 75 GHz and 100 GHz will be measured up to 1500C.

Title:Alternative Flight Control Methods for Supersonic/Hypersonic Cruise Missiles
Abstract:Acree Technologies, Inc. (ATI) has demonstrated the effectiveness of using an innovative Cathodic Arc Plasma Source (CAPS) to produce high-density plasma for pressure changes of over 100% in a Mach-5 flow. ATI proposes to use its CAPS system for actuation of supersonic and hypersonic missile systems. The goal of the Phase-I is to show actuation effects in the speed range of interest, namely Mach 0.5 to Mach 5. Plasma actuators work by coupling electromagnetic energy directly to the flow stream via the plasma without the use of a mechanical intermediary such as a pump, a flap or a motor. By adjusting the plasma density and magnetic field, the lift can be varied between zero and high values. The advantage of this approach is that there are no moving parts, so it is very robust. The CAPS is capable of being energized in a matter of microseconds compared to at least milliseconds for mechanical systems, which allows for increased accuracy of high-speed missiles.

Title:Alternative Flight Control Methods for Supersonic/Hypersonic Cruise Missiles
Abstract:The need to bring ordinance on `targets of opportunity' quickly before the target moves to another location is of paramount importance. A cruise missile that can travel at sustained hypersonic velocities could provide such a capability by reducing the time to target by a factor of 5 or more. Sustained flights at hypersonic velocities provide several technical challenges. Hypersonic control surfaces are typically thick, leading to high drag. High drag requires a high thrust power plant. Technology reducing drag will provide a very favorable trade to the overall missile system. KBM with GTRI propose a concept that utilizes actuators inserting small pins into the missile flow field to provide stability and control for a supersonic tailless missile. Inserting pins at the proper location can achieve high enough pressures on the body of a projectile or missile to produce high speed turns. Preliminary simplified simulation results have demonstrated that pins could be used to make a dynamically unstable tailless missile configuration fly a practically straight path.

Title:ACTUATOR INTEGRATED MISSILE STEERING SYSTEM (AIMSS) FOR SUPERSONIC MISSILES
Abstract:There exists a need for alternative flight control methods for supersonic cruise missiles. Orbital Research Inc. (ORI), in collaboration with the University of Toledo, proposes to develop an innovative Actuator Integrated Missile Steering System (AIMSS) for aerodynamic control of subsonic-to-hypersonic cruise missiles using active flow control technology. ORI's AIMSS will utilize small-scale actuators with efficient flow control techniques to provide controls for missile maneuvering and trimming. The main objectives of the proposed system are to: (a) provide and maintain sufficient control authority over a wide range of flow speeds from subsonic to supersonic flows (Mach 0.5 to 5), (b) minimize weight, drag and power requirements for reduced system complexity, and (c) reduce the overall cost to the vehicle system for practical use in expendables. The proposed AIMSS will aim to reduce or eliminate the need for fins or wings on high supersonic cruise missiles which will also allow the system to be integrated into and launched from various platforms. Other potential benefits of the proposed AIMSS include increased-- range, payload capacity, aerostructural efficiency and endgame maneuvering.

Abstract:Aurora Flight Sciences proposes to apply algorithms for cooperative tasking of multiple unmanned vehicles, which have been significantly matured in UAVs, to a variety of USV littoral search, inspection, and force protection missions. Because of our mature starting point, the focus will be to address real-world issues such as distributed implementation over intermittent communication networks; dynamic, stochastic environments; and management of vehicle loss and other multi-vehicle health management issues. Aurora's existing collaboration with MIT researchers will be expanded to include Woods Hole Oceanographic Institute (WHOI), who together with Aurora researchers with seminal experience in Autonomous Surface Craft will work toward transitioning technologies from the UAV to the USV realm. Cooperative USV/UAV/UUV teams will be considered, in which some members play the role of communication relays (UAVs for host ship-to-USV comms, USVs for host ship-to-UUV comms. Existing multi-vehicle real-time simulations with communication emulation are already available for these studies, and the MIT-developed Robust Decentralized Task Assignment (RDTA) algorithms can be used to optimize planning for flexible, diverse unmanned teams with diverse sensor sets. Extensions to incorporate recent results in multi-vehicle health management and human interfaces to reduce operator work load will also be incorporated.

Abstract:We propose a new miniature USV called Piranha, leapfrogging the normal Phase I study phase and using this time and budget to begin integration of our existing Micro UAV autopilot, the TGE, with cooperative swarming algorithms supplied by JHU/APL. Our GN&C capability currently powers the Locust Micro UAV, and APL has tested their algorithms on larger, much more expensive platforms. During Phase 1, we will integrate both onto an inexpensive, miniature USV. A successful demonstration of this low cost capability shall be followed in Phase 2 by USV capability upgrades including engine and sensor packages, as well as dedicated swarm algorithm testing including Locust MAVs as an airborne component of the swarming behavior.

Title:Autonomous, Cooperative Behavior Amongst Unmanned Surface Vehicles
Abstract:In the future, the U.S. Navy will likely use unmanned surface vehicles (USVs) as an integral part of the Navy's transformation to a networked, more agile force. Navy planners see USVs operating extensively in ocean, littoral (coastal), and riverine areas. USVs are less vulnerable operating on the water's surface than unmanned aerial and submersible vehicles in their respective areas. Unmanned systems are increasingly being used to provide persistent littoral surveillance for a broad range of missions, including reconnaissance, force protection, mine detection, special operations, antisubmarine warfare (ASW), and intelligence collection. The ability for Unmanned Surface Vehicles (USVs) to autonomously operate in a collaborative manner will significantly enhance mission capabilities. Robotic Research, LLC in partnership with General Dynamics Robotic Systems (GDRS), proposes to develop a multi-vehicle, collaborative, autonomous control system for Unmanned Surface Vehicles. Robotic Research and GDRS have already developed and demonstrated similar software for Unmanned Ground Vehicles for the U.S. Army. The system proposed here will leverage the GDRS Autonomous Navigation System (ANS) for vehicle command and control system to the Navy's unmanned surface vessel domain

Title:Erosion Resistance Coatings for Composite Propulsor/Fan Blades
Abstract:Fiber glass reinforced polymers and light weight aluminum have been used in building the structural components for ships and aircraft. As a structural part, these materials are very rigid and strong. On the other hand, fiber reinforced polymer and aluminum do not perform well in a cavitating environment and they can be sand eroded very quickly. These deficiencies are especially serious for the propulsion and lift fans for air-cushion vehicles such as LCACs. The goal of this proposed contract work is to develop cost effective coatings on composite materials for insertion into naval propulsion (in air and in water) and lift fan systems that improve durability by enabling the composite blades to become highly resistant to erosion from cavitation, sand, mist, rain, or sea-water spray while providing compatibility with geometry and ease of installation. This proposal involves with the use of Hontek's high performance sand and rain erosion resistant sprayable coatings to protect the underwater propulsors (ships and subs) and propulsion and lift fans (for air-cushion vehicles such as LCACs). A secondary approach is to use Hontek's molding resins to form a skin layer or molded boot for adhesive bonding onto the composite propulsors or fan blades.

Title:Erosion Resistance Coatings for Composite Propulsor/Fan Blades
Abstract:In the development of high speed surface platforms, such as Littoral combat ship, fiber reinforced composite (FRP) materials offer strength, stiffness, low cost and weight reduction. Most of the fiber reinforced composite materials currently used are stiff and strain-rate limited. Due to poor energy absorbing capability, there is a hurdle in using FRP as a propulsor material. Direction-dependent stiffness in the blades through the use of fiber orientation and flexible propeller blades are used to resolve this stiffness issue in the conventional FRP materials. Despite its effectiveness, it is a very expensive process. In order to manufacture a cost effective composite propulsor, Luna proposes an innovative energy absorbing abrasion resistant coating material on to the low cost FRP propulsor blade. The coating is tough, abrasion resistant and has energy absorbing capability with built-in self-healing feature. This coating system will improve cavitation erosion & abrasion resistance of the propulsor blade and provide a low cost light weight propulsor across the fleet.

Title:Erosion and impact resistant thermal spray coatings for fiber-reinforced polymer applications
Abstract:This Small Business Innovation Research Phase I objective is to develop a cavitation resistant and impact resistant coating system on Fiber Reinforced Polymer (FRP) substrates. The use of FRP materials have many benefits, including stringent fabrication tolerance at reduced procurement cost, hydrodynamic efficiency leading to reduced life-cycle costs, cavitation, radiated noise and weight. Efforts have demonstrated improvements in the cavitation erosion resistance of FRPs, although their improved performance still remains well below traditional metallic materials. Also, although prior research has shown oxidation can be slowed when metallic or ceramic coatings are applied onto FRP's, there remains a need for cavitation-resistant and impact-resistant coatings that protect FRP's from cavitation as well as eroding particulates. A multifunctional composite material that provides both good structural properties and high resistance to cavitation and erosion from a multiple of sources would allow for FRP's to be used in marine applications. Therefore, this Phase I effort is to develop affordable cavitation resistant and impact resistant coating systems (materials and processes) that are compatible with candidate FRP's.

Title:Fire Integrity in Advanced Ship Structures
Abstract:A fully coupled fire simulation and thermal-mechanical response and damage prediction tool will be developed by enhancing, packaging, and integrating our existing solution modules as an add-on tool kit for a commercial finite element solver such as ABAQUS. This tool will for the first time be able to model the fluid-structure coupled response of an advanced ship structure to a fire environment and synergistic interaction of multiple failure modes and their compounding effects that contribute to the final catastrophic failure. GEM has secured commitments for technical support from Virginia Tech and the State University of New York at Buffalo, who will provide supporting data, solution modules, and expertise. The multi-faceted feasibility study consists of: 1) performance of a trade-off study between the commercially available FDS tool and our fully-coupled CFD tool for a 2D structural system; 2) enhancement of the current material characterization module by including creep and creep rupture behavior; 3) characterization of damage initiation and failure progression via a hybrid damage model; 4) implementation of these solution modules in ABAQUS via its user-defined subroutines; and 5) demonstration of the solution efficiency and accuracy based on available coupon and component test data.

Title:Fire Integrity in Advanced Ship Structures (MSC P7002)
Abstract:One critical concern in using advanced materials, such as composite materials and aluminum, in navy ship structures is their structural reliability under fire. Under a previous Navy program, Materials Sciences Corporation (MSC) developed a novel and sophisticated analysis system for the assessment of composite structures under fire. The opportunity under this SBIR program is to bring this system to maturity, and to verify its accuracy and applicability to the fire performance analysis of Navy ships. The package will combine: 1) state-of-the-art material models to predict material degradation of advanced materials under elevated temperatures, including material softening and material pyrolysis, as well as yielding affects of aluminum under fire, 2) established theories, such as classical lamination theory and anisotropic plate theory, to predict overall global behavior of composites for known loading situations, and 3) innovative methods to predict the behavior complex composite parts (i.e., composite joints).This SBIR program will allow MSC to turn a fire-analysis software module into a complete, stand-alone package that may be used by engineers for the rapid assessment of advanced structures under fire conditions.

Title:Predicting Requirements for instructional Environment Design to Improve Critical Training (PREDICT)
Abstract:Traditional military training is becoming increasingly constrained by limited resources, geographic distribution of personnel, and the nature of ongoing operations, leading to an increased interest in the use of virtual training environments. However, training developers and systems acquisition professionals need to better understand how the fidelity of sensory components of virtual environments impacts the effectiveness of training. The PREDICT effort proposes to develop a model-based tool to predict the impact of virtual training environment fidelity on training effectiveness. PREDICT will inform users, prior to investment, of the tradeoffs in training effectiveness associated with levels of fidelity. Aptima will base the PREDICT tool on: (1) a matrix that links virtual environment fidelity to training outcomes, (2) the training context variables that may influence the relationship between fidelity and training effectiveness, (3) the organization's budgetary constraints, and (4) the costs associated with acquiring and maintaining virtual training environments. The result will be a complex, integrated, predictive model which considers all of these variables. In Phase II, Aptima will conduct model-based experimentation to validate the model's predictions. To ensure success, the Aptima team will apply their knowledge of the fidelity literature with their expertise in predictive modeling, model-based experimentation, and experimental design.

Title:Virtual Reality Training System Development Guidance Tool for Multimodal Information Fidelity Level Selection
Abstract:Ensuring that training systems are based on operationally, theoretically, and empirically driven requirements is a key component to improve VE system effectiveness because it focuses on the specific training needs and goals at contextually appropriate task and expertise levels. Although requirements form the basis of system design, their full implementation (i.e., complete realism to the operational environment) is usually limited by practical issues (e.g., cost technological capability). Furthermore, while a high fidelity option may present the most realistic representation of the operational environment, designers should consider a few issues before implementation: 1) Is the high fidelity option meeting the targeted training goals?, and 2) Are there practical, lower cost alternatives offering sufficient levels of functional fidelity to reach the same training goals? In addition to operational context, research theory and empirical findings on multimodal cues and fidelity can help generate viable alternative design solutions and opportunities to augment or enhance VE training system design. To address these issues, this effort proposes to develop the Tool for the Optimization of Multimodal Cues in Advancement of Training System Design (TOMCAT). This tool will partially automate two important components for successful design of VE training systems: 1) Context - helping users define operational/contextual system requirements by identifying critical tasks with their required cues and presentation fidelity ; 2) Optimization (of the requirements) - integrating theoretical, empirical and cost benefit findings to help users select a system both cost-effective and training task centered.

Abstract:This SBIR project will develop a compact, low-cost, ambient temperature operating and ultra-sensitive, wideband laser warning receiver (LWR) based on an ultrasensitivie wavelength dispersive photoreceiver array operating in the 0.4 - 2.5mm wavelength range for shipboard detection of laser threats. We will accomplish this by developing novel ultrasensitive wavelength dispersive avalanche photodiode (APD) detector arrays having low noise, high quantum efficiency and wide-spectral response with each array pixel able to discriminate among wavelengths and angles of arrival of incoming laser signals. In Phase I, we will demonstrate on a single wafer, sub-nanowatt sensitivity, 1-GHz bandwidth detectors with spectral resolution as low as 10-nm at 0.6 um, 0.85 um, 1.1-um, 1.5 um and 2.5 um at room ambient temperature, and show that these detectors can be fabricated as a large format array. In Phase II, we will optimize the detector material and device designs to enable detector pixels with wavelength response varying from 0.4 to 2.5 um. We will then design and fabricate 256 x 256 LWR arrays with 0.1 nW sensitivity equivalent to an irradiance sensitivity of 0.1 mW/cm2 and probability of detection of 90% or one false alarm per hour, as well as a spectral resolution of 10-nm and an angular coverage of 90o.

Title:Shipboard Laser Detection
Abstract:Naval vessels in port or operating close to shore can be threatened by rocket propelled munitions, mortars, or artillery systems that incorporate laser targeting systems (or target designators). The use of laser warning receivers (LWR) which can provide precise pointing to the illuminating laser source can enable valuable situation awareness and targeting for counterfire to protect the threatened platform. Traditional pulsed LWR systems rely on main beam or port scatter from the laser source. Large ships or groups of ships would require numerous such LWR sensors for full ship or group coverage. The feasibility of using atmospheric scattering of lasers as a detection signature has been demonstrated by the Office of Naval Research (ONR) to provide pointing directions back to the laser source. The use of atmospheric scattering minimizes the necessity of multiple sensors for full ship or group coverage. The proposed Phase I is to investigate a sensor systems that will detect and locate a laser beam from the atmospheric scattering of laser radiation over a wide field-of-view and sensitive to lasers operating at visible, shortwave infrared.

Title:Shipboard Laser Detection
Abstract:Sensing Strategies, Inc. (SSI) has extensive expertise in laser detection, which allows us to propose an ambitious effort with a combined analytical and experimental approach. Our proposal includes irradiance and sensor performance predictions to estimate the threat detection envelopes for a sample sensor concept. With these predictions as a basis going into the effort, the Phase I resources can be focused on technology tradeoff and system miniaturization and design issues. Objectives of this Phase I proposed effort are: (1) Develop a shipboard laser warning sensor preliminary design that achieves comparable or improved performance over SBLAS in the 1.06 micron region while reducing the size of the off-axis and direct illumination systems, and (2) Propose an off-axis collection system for laser threat detection in the 1.5 micron range and predict its expected performance in tactical scenarios. The objective of the optional field test component is to collect quantitative aerosol scatter irradiance data to verify the model predictions and characterize sensitivity of SBLAS and a breadboard SSI receiver. The primary product from the Phase I effort will be a development plan for a Phase II prototype sensor system based on the miniaturized designs developed under Phase I.

Title:Microfabricated Circuits for Sheet Electron Beam Amplifiers in the Upper Millimeter-Wave Spectrum
Abstract:A meander-line circuit has been examined, and appears suitable, for use as an RF structure for a sheet beam-based traveling wave tube (TWT). The circuit may be fabricated using both, standard brazing and fabrication techniques typically used in TWT manufacture (for a macro-type device operating in current microwave bands), as well as MEMS techniques for a mm-wave band device. This circuit is characterized by a wide-band (to DC), efficient axial coupling impedances or by a uniquely-transverse mode which can be selected through topology and mode launching. Preliminary calculations indicate significant bandwidth is achievable, possibly octaves and almost certainly, whole waveguide bands. Basic electron beam interaction efficiency should be comparable to that of existing TWT devices and energy recovery methods such as those developed for space-based and MPM technologies may be applied to this device. Recently developed technology in the areas of manufacturing, materials and computational models have made this concept viable. Lithographic/microfabrication methods in circuit design make the MEMS circuits scalable (conceivably to THz applications). NC mills with automation and precision allow the low-cost fabrication of the racetrack shapes required for the beam focusing system. And computational modeling facilitates the more-complicated RF matching between waveguide and circuit and 3-D modeling of the electron beam formation and focusing.

Title:FINAL: Facility Identification via Networks with Adaptive Links
Abstract:Repetitive crimes, such as the production of improvised explosive devices (IEDs) or supplying illegal drugs, present a growing challenge to society. Physical structures that can support these crimes provide potentially important invariants. The crimes must be situated somewhere, and the physical structures present in any given location change slowly. Knowledge of those structures and their capabilities might therefore provide an effective lens through which to gain an accurate view, and therefore an effective means for attacking the problem. Aptima proposes to develop Facility Identification via Networks with Adaptive Links (FINAL) technology to find facilities associated with adversarial actions and discover the intent for their use. FINAL is based on previously developed technology that performs probabilistic network pattern identification based on partial knowledge about network nodes, links and their attributes. Assisted by an ontology of physical structures, FINAL creates hypothesis networks by combining networks of data describing actual conditions and more abstract network models of repetitive crimes.

Abstract:The urban terrain shapes the strategy and tactics of both our adversaries and our military in the Global War on Terror. Hostile actors use man-made structures (facilities, buildings) for specific tasks and purposes (planning, supply, reconnaissance). The structures they use can be profiled in terms of their attributes (location, size, access, features, egress, utilities) and their utility (safe house, IED factory, observation post). Geoprofiling, a technique used in serial crime investigations, can also be applied to counter insurgency operations. However, like any analytical method, the benefit of geoprofiling is dependent on the specific application (i.e., criminal investigation), the availability of `good data' to support the analysis, and the understanding of regional differences. Here, we propose to research and develop a data-driven, decision aid for facility and spatiotemporal profiling (D3A-FSP) that, given a set of adversary goals, finds the utility function from observed adversary behavior and generates inferences and predictions regarding the location of facilities that support adversary operations in the urban environment. D3A-FSP learns the utility function that the adversaries are using, and classifies and predicts the potential utility of a facility to the adversaries based on the derived metadata of each facility using belief networks.

Title:Predicting Facilities that Repetitively Support Hostile Activities using Adversary Modeling and Geographic Profiling
Abstract:Stottler Henke proposes to develop a software system to predict which facilities in an urban environment are likely to repetitively support activities by hostile actors. This system will draw upon an extensible, heterogeneous geographic information system containing detailed geographic and facility data as well as a knowledge base storing information about past hostile actions and known adversary tactics, structure, and associations. The system will employ a combination of geographic profiling techniques and adversary decision models - which capture the facility preference criteria and constraints of the adversary -- to dynamically generate effective predictions based on the latest information. Using machine learning algorithms, the system will automatically adapt its adversary decision models to account for regional differences or changes in adversary tactics over time. The system will also exploit the structure of the knowledge base ontology to generalize and aggregate adversary knowledge where necessary to mitigate gaps in the data. During the Phase I, Stottler Henke will characterize the data sets required for effective prediction of supporting facilities. We will also develop predictive algorithms as described above as well as learning algorithms to adapt to evolving adversary tactics. Finally, we propose to demonstrate the feasibility of our approach via a limited prototype.

Title:Submarine UHF SATCOM (25 kHz CPM) Narrowband Interference and Multipath Mitigation with Nonlinear Adaptive Filtering
Abstract:We propose to develop innovative nonlinear adaptive filtering techniques to simultaneously mitigate the effects of narrowband interference and multipath distortion for the 25 KHz Continuous Phase Modulation (CPM) MIL-STD-188-181B waveform for submarine communications and other DoD applications. Our approach is based on an extension of nonlinear adaptive filtering techniques that we developed and successfully applied to the 5KHz Shaped Offset Quadrature Phase Shift Keyed (SOQPSK) MIL-STD-188-181B waveform in previous work. These algorithms will be redesigned to provide effective performance with the 25 KHz CPM waveform in the presence of both CW interference and multipath distortion. In Phase I, we will provide a complete software receiver capable of signal acquisition and subsequent tracking of frequency, phase, timing, and the Reed-Solomon coding and Viterbi detection functions specified in MIL-STD-188-181B. The filters developed will be robust to the high levels of interference frequently encountered in tactical networks, and will solve the tactical requirement of interference mitigation with minimal signal distortion by the development of a multi-stage nonlinear adaptive filtering approach that is able to recognize the start of the preamble and acquire and track the 25 KHz coded CPM waveform in the presence of severe CW narrowband interference.

Title:Submarine UHF SATCOM (25 kHz CPM) Narrowband Interference and Multipath Mitigation with Nonlinear Adaptive Filtering
Abstract:Xenotran proposes to design an adaptive filtering system capable of mitigating the effects of narrowband interference and multi-path distortion on a Multi-h Continuous Phase Modulation (CPM) modulated channel. The adaptive filtering system will be based on the Least-Mean-Square (LMS) algorithm and will exploit the non-linear behavior of LMS to improve system performance. This system will also capitalize on turbo equalization techniques, iterating between equalizer and soft-input soft-output (SISO) demodulation of the quaternary, Multi-h CPM trellis to further improve system performance. Such an iterative adaptive filtering system is directly applicable to UHF SATCOM receivers, specifically receivers complying with the MIL-STD-188-181B/C standards, where narrowband interference and multi-path distortion are of concern. This system is particularly useful in littoral environments, where reflections from the sea surface create multi-path distortion and where ducting conditions can cause an increase in received interference.

Title:Advanced Materials for Submarine Antenna Radomes
Abstract:This proposed SBIR program would develop low loss, structural, high performance polymer matrix nanocomposites with controlled permittivity for radome applications. A radome's function is to protect the antenna, modify the impact of the antenna on the hydrodynamics, and the radar cross-section of the mast. However, its impact on the electromagnetic function of the enclosed antenna in free space must be minimized. To meet this challenge, NanoSonic will fabricate and characterize conformal, high performance, low loss polymer matrix nanocomposites with controlled permittivity. With the electrical and mechanical requirements, NanoSonic would build-in advantageous environment material properties. The result is a highly integrated radome panel designed as not only an electromagnetic solution but also as a materials solution with a low-cost, highly reliable, manufacturable product. NanoSonic is uniquely qualified as a small company to construct these materials. Our staff consists of innovative chemical engineers, polymer and inorganic chemists holding advanced degrees, and as engineers with experience in microwave antenna engineering and high frequency materials testing. Our laboratory is fully equipped for polymer and nanoparticle synthesis and has fabrication capabilities to create prototype structures, and our microwave testing equipment includes the capabilities for making in-house measurements for permittivity.

Title:DaSD - Dynamic Service Discovery
Abstract:The current UDDI standard does not support dynamic federation of registries in the Navy's disconnected and low bandwidth environment. To support these dynamic, multi-enclave federations while keeping security policies in place, ATC-NY, in collaboration with Architecture Technology Corporation, will develop DaSD (Dynamic Service Discovery). We will employ a modified gossip protocol to enable UDDI registries to be dynamically distributed while using XML compression technology to meet low-bandwidth requirements. To determine feasibility in Phase I we will create a proxy server which clients will transparently use to connect to UDDI servers. The proxy server will keep track of added/removed/failed nodes as well as security policies to be enforced. The proxy server will also manage replication among UDDI nodes. We will also build a prototype simulator, which contains the same events of a dynamic UDDI federation in a low-bandwidth network, to run experiments and optimize the performance of DaSD. By combining the strength of UDDI 3's features and DaSD's capabilities, we should be able to support the Navy's requirements for federating UDDI registries between afloat and ashore networks.

Title:Standardizing a Multi-Enclave Federated UDDI for Use in a Dynamic Service Oriented Architecture
Abstract:Fulfilling the promise of a net-centric service oriented architecture for information systems depends on the availability of dynamic discovery of services. The premier standards-based service oriented architecture of today is based on Web services; the specifications include those for the Universal Description, Discovery and Integration (UDDI) Registry service. These specifications are geared to the eCommerce world; the development of UDDI standards supports development of commercial-off-the-shelf software tools. As long as the UDDI specifications meet the needs of the Navy, it is able to leverage the commercial tools for its mission needs. Problems arise when there is a mismatch of Navy needs and the specifications or standards. Our innovation offers a standards-based solution to the Navy needs with our proposed Multi-Enclave Federated UDDI (MEF-UDDI) framework for use in a Dynamic Service Oriented Architecture. The MEF-UDDI will support federation of UDDI registries, policy-based access to registry service information and agent proxy capability. In order to realize the MEF-UDDI, we propose a two-fold approach, with (1) engagement with the standards organization OASIS and the UDDI TC in order to address development of architectural recommendations and potentially new (or extended) specifications that serve Navy needs and (2) a software agent-based implementation.

Title:PathFinderT: A Reconfigurable Predictive Software Agent for End-to-End QoS in MANETs
Abstract:Mobile Ad hoc Networks (MANETs) are becoming increasingly more important to a variety of miniature, mobile communication applications. None are perhaps more important than applications to support our troops in the battlefield and homeland defense. As MANET architectures become more prevalent and the number of dynamic network nodes increases, emphasis must be placed on ensuring a high quality of communication service is delivered between end-users within this highly dynamic environment. NanoVision Technologies, Inc. is developing a new, innovative mobile ad hoc mesh networking (MANET) technology that ensures End-to-End (E2E) Quality of Service (QoS) for mobile platforms. PathFinderT is a highly efficient, completely autonomous agent-based routing and QoS protocol that achieves guaranteed delivery of data by mapping the best possible path within a dynamic MANET. Our innovative scheme involves both the signaling protocols for distributing historical and predictive network state information and the underlying methodology for achieving reliable and efficient operation of the communications infrastructure through dynamic resource re-allocation. Optimum E2E traffic flow is managed by the transfer of multi-link "Traffic Signals" that transfer minimum information between nodes adaptively so that the MANET as a whole is "self-aware" and "self-reconfigurable" with as low overhead as possible. The novel PathFinderT architecture provides a method to achieve reliable communications through adaptive cognitive self-optimizing communications.

Title:A Reconfigurable Wireless Ad Hoc Networks Architecture for Quality of Service Support
Abstract:This SBIR submission describes a proposal by XPRT Solutions Inc. - a DSCI Company, to develop a dynamic QoS aware agent for Manet networks. This effort considers the adoption of four applicable technologies, namely; Measurement Based Admission Control (MBAC)(that enables the network to respond to perceived status based on a measurement of network performance), Cross Layer Signaling, QOS Edge Technology (that supports various functions including reactive flow control, proactive flow control, delivery assurance, IA, and packet policing) and Network Topology Based on Governing Dynamics (that enables the network topology to be modified to maximize network throughput under various loading conditions). The overall QoS-aware design will consider the major areas of QoS to include Per-Hop, Path, Overhead Traffic and Applications. These areas will be applied in support of identified network functional requirements/identified network capabilities that need to be provided in support of the E2E QoS requirements. A Proof-of-Concept demonstration will be conducted towards the end of Phase I assessing the agent in terms of established performance metrics. A Phase I Option period is proposed for development of detailed systems architecture and prototype component development (e.g., adding new QOS edge technologies based on functional requirements).

Title:CINAPS: Composable Interfaces for Networked Applications
Abstract:We propose to produce CINAPS - Composable Interfaces for Networked Applications - a unique environment allowing operators to effectively compose interfaces for networked command and control applications. Using the unmanned vehicle domain as a command-and-control test case, this environment will provide for flexible information composition but will do so in a task-based framework, thereby removing the penalty incurred in time and effort when users must assemble their own interfaces. Aptima will apply Cognitive Work Analysis (CWA) to develop principles for interface composability, and to realize those principles within a functioning interface composition tool, CINAPS. The result will be a flexible environment and user interface that ensures optimal operator behavior in assembling multiple information sources into a coherent display for decision-making. In Phase I, we will define composability principles through application of CWA techniques, develop a storyboard to illustrate the products and operation of CINAPS, design the functionality and software architecture of CINAPS, and plan evaluations and formative assessments. In Phase II, Aptima will fully implement CINAPS for a broad set of missions and conditions and conduct a thorough assessment of its utility and usability.

Title:Prognostics and Health Management (PHM) for Afloat Information Technology (IT) and Network Services
Abstract:goes hereBeacon's approach to Topic N07-108 is aimed at providing not only prognostication and prescription, but the ability to act upon that information. As we explore the needs of afloat IT Systems, our focus will not center on new algorithms or system models. Because of the intense marketplace competition currently going on to provide network and system support at the BIT/BITE level, we do not believe our time would be well spent competing in that market space. Instead, we are interested in exploring how the results of these stand-alone prognostic and diagnostic solutions can be leveraged into a single and coherent support capability for an entire ship. There is a need for tools that automate and make efficient the use of this data to create a distributed diagnostics capability. The challenge in managing an environment such as this is the plethora of components utilizing different protocols, operating systems, hardware components and software protocols which are providing a wide range of services. Additionally, fault in one area can have a cascading affect and the ability to correct this type of degradation is difficult. Ultimately, our goal is to create a support system that seamlessly creates an interconnected grid of collaborative operations.

Title:Prognostics and Health Management (PHM) for Afloat Information Technology (IT) and Network Services
Abstract:Qualtech Systems, Inc., in cooperation with University of Connecticut and Lockheed Martin Corporation, propose to develop an integrated on-line and adaptive remote network PHM solution to address the needs of shipboard IT/Network systems and services. The team proposes a network system model suitable for fault localization, which takes into account the fault-to-failure progressions among the different components and/or subsystems. We also propose advanced prognostic techniques to predict discrete events (e.g., router failures), as well as continuous network performance measures (e.g., response time, throughput). The proposed solution performs smart tests (e.g., network probing, database query) on network components and coordinates multiple subsystem health assessments to arrive at an overall network health assessment. For further fault isolation, the solution provides adaptive guided troubleshooting support for the maintenance personnel onboard or onshore. In addition, the solution provides various prediction algorithms tailored to the task of projecting the future network health status for improved Maintenance and Material Management. The work proposed here seeks to developing methods for improved diagnostic accuracy (i.e., root-cause isolation), online implementation (efficient test sequences, fast inferencing), as well as the capability for Remote Diagnostics which provide opportunities to conduct diagnostics remotely and prevent breakdowns by detecting and isolating faults earlier.

Title:Adaptive Polyquadratic Algorithms (APA)
Abstract:The U.S. Navy is looking for innovative technologies providing Interpolation Techniques with Minimal Data Density Analysis for Seafloor and Sub-seafloor Characteristics. In response AGNC proposes to develop and document an innovative computationally efficient solution deploying adaptive polyquadratic algorithms (APA). The APA system will encompass: 1) extraction breaklines and extreme points from initial surface and subsurface geospatial models; 2) filtering and point's cloud processing of in-situ LIDAR bathymetry and other sensors; 3) adaptive breakline model filtering of assigned accuracy with generation of polyquadratic coefficients; 4) restoration of elevation at any given point of interest deploying polyquadratic coefficients. To develop the APA system, AGNC will research the mathematical and geostatistical nature of the problem to specify optimal algorithmic configurations of system components and interpolation accuracy sufficient for the Navy operations. The APA solution, proposed by AGNC, comprises the following major innovations: a) integration for the first time of adaptive filtering and polyquadric interpolation algorithms; b) unique geostatistical prediction of the final product's surface accuracy and level of detail. The Phase I research will result in identification and feasibility verification of the APA's most challenging components. Phase II will culminate in a fully functional working prototype.

Title:Seafloor and Sub-seafloor Data Interpolation and Minimal Data Density Analysis using Geometric and Multi-scale Markov Models
Abstract:The objective of this project is to develop minimum data density and interpolation algorithms suitable for large volumes of Geospatial Information & Services (GI&S) survey data and for real-time or near-real-time use by decision makers. To accomplish this, we propose two different architectures to impose the Markov conditions -- the Geometric Markov model and the Multi-scale Markov model. The Markovian property in both architectures have direct connections to the underlying physical properties of natural processes. Furthermore, both architectures permit efficient computation algorithms to be implemented for both the data interpolation and the interpolation error estimation. This latter feature permits us to quickly assess different survey strategies and establish the ``best trade-off between resources invested and interpolation error.'' Phase I work will be conducted in the following areas: (1) Identification of Data Spatial Variability, (2) Data Interpolation, and (3) Minimal Data Density Analysis. The end-product of Phase I will be Matlab programs that implement the data interpolation and error estimation algorithms. Phase II end-product will be a prototype of the survey planning system readily to be integrated into Naval METOC Production Centers sensor systems. Our team consists of Scientific Systems Company, Inc. (SSCI) as the prime contractor, and Dr. John Goff of University of Texas Institute for Geophysics as a consultant for this project.

Title:Multi-input Synchronous Digital-RF Receiver
Abstract:The goal of this project is to develop an all-digital receiver system, incorporating multiple synchronous analog-to-digital converters, to enable direct digital reception from an antenna array, which permits tunable digital beamforming. HYPRES has been developing superconducting digital-RF receivers for the Navy and other DoD users based on an ultrafast ADC (sampled at over 20 GHz), featuring outstanding linearity due to intrinsic quantum accuracy. This ADC design has matured over the last decade and already exhibits an impressive spur-free-dynamic range (SFDR) greater than 100 dB and 86 dB signal-to-noise ratio over 10 MHz instantaneous bandwidth. We have also demonstrated extremely low-jitter (< 10 fs) on-chip long Josephson junction clock sources in the 10-50 GHz range. In Phase I, we propose to design, fabricate, and demonstrate a two-input prototype chip integrating two such ADCs with a common clock source, and two on-chip digital decimation filters. In addition, we will develop a multi-chip module scheme for extending this design to multiple (8-16) RF inputs, and to multiple RF bands (HF, VHF, UHF, etc.). Our goal in Phase II is to deliver a set of chips along with the necessary cryogenic and room-temperature hardware for evaluation to SPAWAR System Center.

Title:Innovative Wideband All Digital Receiver (ADR)
Abstract:ISL propose to combine state-of-the-art advances in signal processing algorithms and architectures and superconducting electronics to design and fabricate an essentially all-digital receiver (ADR) that will both mitigate the effects of EMI and reduce digital storage requirements. An innovative Analog-to-Information (A-to-I) converter approach will be designed that eliminates many of the redundant bits during the conversion process. The unique aspect of ISL's approach is the use of linear predictive processing in conjunction with implicit non-uniform sampling. Non-uniform sampling is required to incorporate a linear predictor into the concept to achieve data reduction. In this approach, the RF signal from the antenna is bandpass filtered with a pre-selection filter that uses High-Temperature Superconducting (HTS) filters in order to define the input bandwidth and suppress out-of-band interference. The difference of the output from the pre-selection filter and the output of the linear prediction filter generates a prediction error signal. For many military systems the single most important piece of prior knowledge is that the desired signals are weak with respect to the other signals within the band. This observation means that in many applications, prediction of the strong signals followed by subtracting them out of the composite in-band signal mix, is an attractive method to reduce the dynamic range of the received signal and thus the number of digital bits required to represent the signal.

Title:Global Information Grid (GIG) Tactical Edge Networks (TEN)
Abstract:Timely data is critical for decision making to fight the Global War on Terror (GWOT). With the availability of numerous networks and protocols in the market, sharing data among wired and wireless networks securely in real time is complex. Sharing data and voice amongst a network of networks requires robust innovative software that routes Situational Awareness (SA) data and voice reliably and securely. The proposed software application, Situational Awareness For Global Information Grid (SAF-GIG), will provide reliable and secure inter-networking capabilities amongst the network of networks for SA data and voice in near real time. SAF-GIG's innovative approach stores the data/voice locally on ships (with ISNS/ADNS systems) and shore-based user systems, and makes it available for other ships and shore users. The data and its management will be distributed to mitigate any loss of access to data during the mission due to lack of connectivity to a particular user. Trident's approach will ensure flexibility, modularity and use of COTS products. Trident's intention is not to provide a global solution for all warfare requirements for situational awareness, but to implement a framework that can fit into any well-designed information architecture.

Title:Modeling and Simulation for Higher Fidelity of Commercial SATCOM Capability as a Design Aid to the Planning and Decision Making Process.
Abstract:This proposal is to develop a SATCOM resource model/toolset to provide the military SATCOM community the ability to examine communications systems' performance with respect to achieving maximum data rates for a given set of SATCOM terminals. The model will analyze the transmission capacity of potential SATCOM systems based on the required traffic and other factors including site location, characteristics of terminals and transponders, rain rate statistics, etc. The tool will allow users to allocate SATCOM carriers and assess transponder bandwidth for specific SATCOM products. The efforts for Phase I entail the establishment of a network model for the warfighting scenario that will consider traffic from different classes of services and different message precedence levels. A SATCOM library to support a high fidelity assessment of SATCOM terminals/components will be built within OPNET. The proposed model will consist of three major parts: communications traffic and analysis modeling, SATCOM resource and link analysis modeling, and SATCOM performance assessment modeling. The Phase I effort will apply/consider the technical approaches and analysis methodologies employed in the development of the related SATCOM Network Planning Tool and conclude with a proof-of-concept to demonstrate the functionalities and capabilities of the proposed toolset.

Title:On the Edge: Hybridized Distributed Storage
Abstract:In this proposal, we define our approach for researching methods that provide distributed lookup and distribution of files using a variety of existing peer-to-peer networks models. We will need to research and to define the metrics for measuring the relative effectiveness and reliability of the distributed system versus the client/server model. We also must address the issues of security, synchronization, and revocation of data and consider deployment within a DoD context. The conclusion of Phase I, is a presentation of our findings to the sponsor and a notational demonstration that shows some of the real-world deployment issues and solutions of the research.

Title:Linked List Archiving Protocol
Abstract:To address the U.S. Navy need for hybrid distributed data storage based on peer-to-peer (P2P) design principles, Physical Optics Corporation (POC) proposes to develop a new Linked List Archiving (LILA) P2P-based system with error correction, unique portioning, and flexible load balancing for file distribution. LILA's highly redundant linked list file structure eliminates the central trackers common to existing P2P methods. An innovative dual stage error correction and partitioning routine minimizes file corruption, making LILA fault tolerant. The encryption routines are FIPS 140-2 compliant. LILA imposes minimal network overhead, and is highly available, both advantages of P2P approaches. File distribution is based on load balancing, and a novel priority-sensitive distributed hash table doubles as an indexing and caching routine. LILA innovations will enable the system to perform truly distributed data storage for digital libraries and data archives. In Phase I POC will demonstrate the feasibility of LILA by developing the core software and implementing a LILA prototype. In Phase II we plan to add duplicate elimination and security to LILA, and optimize the software elements.

Title:An Optimal Distributed Storage System for Large Network Environments
Abstract:The research effort described in this proposal is designed to lay the foundation for the development of a massive distributed network storage system. The specific purpose of the proposed work is to determine which features and functionalities in a Peer-to-Peer based architecture are most likely to provide a satisfactory solution to the distributed storage problem. In the course of the analysis we propose to develop a baseline conceptual model of the software architecture and use this as a blueprint for the development of an integrated set of functional models for the system. Using the results of this research, along with the functional prototype models, it should be possible to build optimal distributed storage software tailored for use in large network environments.
