Title:Development of Low Cost Titanium Alloy Feedstock for Casting of Net Shape Combat Vehicle Components
Abstract:Dynamet proposes to develop its Low Cost Feedstock Process (LCFP) for producing casting feedstock by the consolidation of processed titanium machine turnings. Dynamet will demonstrate that LCFP has the potential to produce low cost, high quality cast components for combat vehicles. Preliminary analysis indicates that LCFP offers a 27-44% cost savings over current ingot producing methods. This significant cost advantage has the potential of reducing the price of military cast components by 16-30%. LCFP offers other potential advantages including (1) low capital cost, (2) rapid addition of incremental capacity, (3) improved homogeneity, (4) ability to economically modify compositions to specific requirements, and (5) ability to produce small lots. Dynamet will produce Ti-6Al-4V LCFP billets to three density levels. Billets will be assessed through melting and casting trials conducted at Howmet. Test plates will be cast from the billets and compared to standard Ti-6Al-4V plate. LCFP cast plates will be evaluated by radiography, metallography, tensile tests and chemical analyses. Technical and economic analyses will be conducted. During the Phase 1 Option a production-size LCFP billet from optimized process will be manufactured in preparation for Phase II which will include casting and evaluation of a selected vehicle component, e.g. an EFV sprocket carrier.

Title:Innovative Hybrid Molding Technologies for Titanium
Abstract:This SBIR Phase I effort proposes to develop an innovative, more affordable titanium casting technology based on hybrid molding technologies. Rammed graphite molding is a lower-cost casting process not traditionally used to manufacture aerospace titanium components, while hybrid molds are a combination of two or more non-traditional molding technologies. The new process is expected to yield sufficient microstructure, mechanical properties as compared with the current investment casting method, with sufficient part geometrical complexity capability and surface finish when supplemented with added-value fabrication methods.

Title:Safe Storage, Transportation, and Use of Chemical Hydride based Hydrogen Generators for Portable Fuel Cell Applications
Abstract:Presently, infrastructure for the transportation and storage of packaged fuels remains the limiting factor to the widespread use of portable fuel cells. Significant effort is currently underway to test and regulate several packaged fuel options, including concentrated and dilute methanol packages, metal hydride based hydrogen storage systems, and logistics fuels. Although several early portable fuel cell products plan to utilize chemical hydride based hydrogen generators as the fuel, little effort has been focused on this class of packaged fuel. The anticipated widespread adoption of portable fuel cell systems utilizing chemical hydride fuel packages will be delayed unless proper attention is focused on this packaged fuel option. Taking advantage of its experience in developing fuel cell systems utilizing a variety of packaged fuels, Lynntech proposes to implement an accelerated program to identify, develop and demonstrate necessary technology and means to safely store, transport, and use chemical hydride based packaged fuel systems for use with portable fuel cell systems.

Title:Fuel Cell Supply Integration and Safety
Abstract:Man-portable fuel cell systems are currently being developed that could replace batteries and provide extended run-time power systems for U.S. Marine Corp tactical systems. However, little attention has been paid on how to safely store, transport and use fuels such as hydrogen, methanol, butane and sodium borohydride that are proposed to run these fuel cell power systems. DOT and DOD regulations that address storage, transportation and use of hazardous materials need to be investigated and defined in order to develop fuel cell tank systems that will meet all DOT and DOD safety requirements. This project proposes to develop man-portable fuel cell tank systems that will meet all DOT and DOD storage, transportation and use safety regulations, allowing fully fueled fuel cell tank systems to be stored and shipped using all approved modes of transportation, including naval aircraft and ships. A cost/benefit trade-off study will be conducted to rank the proposed fuel types and conceptual designs will be developed for at least two fuel cell tank systems using two different fuel types. The fuel cell tank system design concepts will be lightweight, man-portable, low cost, durable, fire, impact and corrosion resistant, and compatible with all storage, transportation and operational environments.

Title:Sensor for Simultaneous Movement and Directed Weapons Fire in Day/Low/No-light.
Abstract:H.E.A.T. has experience in designing and building advanced indirect view multi-spectral fusion night vision goggles utilizing HMDs. The requirements for the Warfighters are somewhat different than our current products, but are well within our capabilities. Recent advances in technology will cover a number of the improvements. We propose several innovative ideas to meet the needs of the Warfighter Corps. Our proposal is a triple band fused image displayed on a twin display HMD. Some of the high points of what makes our approach different are: A) SWIR for covert movement and target illumination. B) SWIR tracking of the covert laser pointer for tracking the aim point of the weapon and displaying an icon on the HMD showing this position without the use of position sensors that will not work reliably in MOUT and other important situations. C) Improved movement capability via either stereo or peripheral vision. D) MAP Picture-In-Picture or full screen with overlaid situational awareness icons obtained from the tactical internet 2525B interface. E) 6X thermal weapon sight being related to an ROI/box display at the correct scale. F) Moving Target Indicators (threat detection) while the Warfighter is either stationary or moving. G) Spot metering for the I2 camera to allow the user to maximize dynamic range in Cave and Urban Assault. H) iStorm interface bringing in ELRF capability. (If the Warfighter Corps does not use iStorm, we are willing to interface to the ELRF the Marine Corps selection for this subsystem).

Title:New Modeling and Simulation Technology for Night Vision Goggle Mission Rehearsal
Abstract:The proposed study will examine the Navy's NVG mission rehearsal requirements in depth, compare the requirements with available technology and with technology currently in the process of being made into products, and derive an improved system design that will meet the requirements. The study proposed is comprehensive, including database preparation, software, graphics and sensor simulation hardware, and displays. The study is proposed to encompass a range of possible training scenarios ranging from that of a real or simulated cockpit, through a mobile standalone trainer, to a manwearable training device. The requirements and solutions derived in the study will be integrated with current technology in a spiral development process. We propose to demonstrate existing fielded night vision technology at the Phase I kickoff meeting. At the conclusion of Phase I, we will demonstrate elements of the latest technology that we are developing independent of this SBIR and present, in a Final Report, the results of the Phase I analysis of potential improvements. In the Phase I option, we proposed to integrate the best available component technology into helmet-mounted display based PC system that will mark the baseline for the start of Phase II, to which the features identified in the Phase I Final Report would be incrementally introduced.

Title:Night Vision Simulation with Programmable Real-Time Shaders
Abstract:To address the Navy's need for Night Vision Goggle (NVG) instruction and training system, Physical Optics Corporation (POC) proposes to develop a new Nightvision Operation Computer Training Under Realistic Naval Environments (NOCTURNE) system. This proposed technology is based on the use of programmable shaders within modern graphical processing units to generate simulated night vision imagery for training and mission rehearsal. The system will offer a compact, flexible, and inexpensive means of simulating the unique aspects of night vision operation, particularly illusions: maritime and metrological effects in conjunction with an interface for the real-time operation of head-mounted displays (HMD) equipped with motion tracking sensors. In Phase I, POC will demonstrate the feasibility of the NOCTURNE system by demonstrating rendering of selected test terrain via the use of commercially available GPU cards. In Phase II, POC plans to develop an easily integrated modeling and rendering system capable of independently training personnel, as well as providing imagery for general purpose simulation systems.

Title:High Thrust, Integrated Roller-Screw Actuator Using High Performance Notched-Ribbon Motor Technology
Abstract:The Navy is seeking a high thrust, electric linear actuation technology capable of replacing the hydraulic actuators currently used aboard Navy ships. Of particular interest are devices suitable for the aircraft carrier weapons flight deck hatch and jet blast deflector. Proposed for this is a design based on a high-thrust roller-screw integrated with an innovative, high-torque motor. This motor technology is based on a dual-airgap, axial-flux, permanent-magnet machine topology and utilizes a unique notched-ribbon wave winding and flux-focused magnet arrays. The high performance provided by this design is expected to result in a high thrust electric actuator of comparable size, shape, and performance to current hydraulic technologies. The goal of this Phase I effort is to establish the feasiblity of the proposed design for Navy shipboard applications by developing a preliminary design of this concept and comparing predicted performance and physical attributes to an established set of metrics (success critera).

Title:Linear Actuator Using SR Motor & SiC
Abstract:The proposed high thrust linear actuator has three innovative elements. The first is the use of a switched reluctance motor, which is the most rugged and fault tolerant of all motor types. The second is the use of power electronics with SiC power semiconductors, which are rugged, have much better performance than standard silicon, and enable a dramatic size reduction. The third is a highly efficient lead screw with rollers rather than standard ball bearings. This mechanism gives the necessary mechanical advantage and is an order of magnitude more durable than alternative lead screws. In the optional work, the power electronics will actually be incorporated into the motor, which is an opportunity enabled by exploiting the high temperature capability of SiC. The net result is a reliable, rugged and low maintenance linear actuator system that is self contained. Most components are modularized to permit widespread replacement of hydraulic actuators with little application-specific design work.

Title:Novel Nano-Laminated Fe Soft Magnetic Materials with High Flux Density
Abstract:We propose to develop a novel nano-laminated Fe magnetic core material. With our proprietary technique, we have developed a process to create Fe sheets of hundred nanometers thick. By coating these Fe sheets with a thin insulating layer and subsequent consolidation, we can achieve nano-laminated soft magnetic Fe cores, which is a nano-scale version of the conventional laminated silicon steel cores. This innovation makes it possible to form and preserve the nanometer sheet structures during the process. The process greatly simplifies the manufacture procedures and reduces the cost. The net-shape capability further reduces the cost. The materials have low weight and are anticipated to have good mechanical properties. More importantly, it is likely to achieve high magnetic flux density over a wide frequency from dc to MHz range, surpassing any current commercial materials. The proposal objective is the feasibility demonstration of fabricating nano-laminated Fe cores with high flux density close to 1.9T, low weight, low cost, and good mechanical properties. Specifically, we will (1) determine the experimental conditions to form nano-laminates; (2) optimize the structure to achieve good magnetic properties; and (3) achieve dense compacted samples with magnetic and mechanical properties similar to those of M-19 silicon steel.

Title:Submarine Automated Simulation (SubAutoSim)
Abstract:There is strong requirement to field an interactive simulation environment that will model tactical and environmental entities in real time and enable goal-directed scenario generation. This capability is especially desirable in system integration, testing, certification, training and life-cycle support activities. 21st Century Systems, Incorporated (21CSI) proposes to leverage our extensive expertise in command and control decision support and simulation and produce a state-of-the-art submarine simulation system for Virginia Class SSN crew training as well as Non-Propulsion Electronics System development. We call our concept the Submarine Automated Simulation (SubAutoSim). SubAutoSim is an intelligent agent-driven simulation environment and intuitive situational awareness client application that allows the user to rapidly build a simulation situation and to inject scenario changes mid-simulation in order to improve realism for systems development and training activities. Intelligent agent controlled components provide the capability for goal-driven entities. The client application will include advanced visualization with 2D and 3D components and a multiple user interface capability including voice, mouse, and joystick. The SubAutoSim concept also includes an intuitive scenario builder that allows rapid scenario development and scenario injects during execution.

Title:Synthetic Lubricating & Hydraulic Oil for Motion Control, Steam Turbines and Gears, Military Symbol 2190-TEP Replacement
Abstract:Existing MIL-PRF-17331 organic petroleum based (mineral) fluids (military symbol 2190-TEP) no longer exhibit acceptable performance at the high performance levels required of Navy submarine platforms. The service life of fluids procured in accordance with MIL-PRF-17331 have experienced high depletion rates of fluid anti-oxidant (AO) additive packages, sharp increases in fluid Total Acid Number (TAN) and severe off-gassing events during the extended operation. In addition, increasingly high oil replacement and disposal costs consume dwindling fleet maintenance dollars. New lubricant formulation technology is needed to deliver high quality synthetic fluids to the fleet that are capable of extending operating service life, and exhibiting a high resistance to the fluid degradation and oxidation phenomena. Under the proposed program, METSS will formulate and produce completely new synthetic lubricating and hydraulic fluids that will lower shipboard maintenance costs, improve the operational readiness of various critical ship systems, and extend the performance and service life of high precision propulsion and motion control devices shipboard. To meet the Navy's requirements, METSS will focus on combining hydrolytically stable synthetic basestocks and additives to produce a new class of marine lubricants with superior performance properties with respect to antiwear characteristics, oxidative stability and corrosion protection. The proposed program will also address additional issues related to personnel safety, environmental impact and use costs.

Title:Simulation Environment for Complex, Man-in-the-Loop, Real-Time Systems
Abstract:As the United States strives to implement a more network-centric approach to warfare, solutions to improving system interoperability often overlook the consequences of system modifications on the more complex aspects of the battlefield environment. These complex aspects include strategic asset allocation; warfighter response, decision time delays, and workload; and communications bottlenecks. A method to effectively model a distributed battlefield environment that is able to capture and identify various metrics on issues such as workload prediction, system saturation, and asset cost and performance trade-off analysis would be extremely beneficial in reducing system errors caused by unforeseen effects of new network-centric technology. Through the use of the distributed battlefield environment simulation metrics, modeling of command and control (C2) networks would afford the Department of Defense (DoD) community the opportunity to utilize discrete event simulations to effectively reduce risk while enhancing interoperability. As an innovative approach to a C2 network environment simulation, Lakota proposes to develop an Open Architecture Battlefield Environment Simulator (OA-BES) that will be able to build upon discrete event simulations to form a setting that will allow a user to carry out performance trade-off and cost analyses of new system development through the collection and identification of various metrics.

Title:High Power Limiters based on Silicon Carbide (SiC), and Gallium Nitride (GaN) Device Technology for Phased Array Radar ( L,S and X-Band), Communications and EW Applications
Abstract:Naval vessels today are equipped with a large variety of electronic equipment for radar functions, communications, navigation, countermeasures, and others. Many of those shipboard systems operate with transmitters emitting thousands of watts of power in microwave frequencies, and the presence of high-power transmitters in close proximity to sensitive receivers. This proposal is addressed to the development of broadband microwave limiters using wide band-gap devices of those technologies suitable for applications in microwave frequencies, namely silicon-carbide (SiC) PIN diodes. SiC transistors are used in high-power microwave amplifiers applications, but there have been virtually no studies of the application of SiC devices as signal control devices such as switches and attenuators and limiters. The proposed program will be focused on development of limiters for receiver protection. The Phase 1 effort will lead to a full assessment of SiC PIN capabilities for microwave limiter applications, definition of design goals for broadband limiters and design approaches. The ensuing Phase 2 program will be focused on design, fabrication and characterization of SiC PIN devices and limiters. Successful implementation of limiters in compact form will protect sensitive shipboard receivers against both friendly radar emissions and hostile high-power microwave (HPM) threats.

Title:High Power Microwave Limiters based on GaN Technology
Abstract:We propose to develop power limiter based on Schottky diodes over AlGaN/GaN structure. The limiters would have the capability to integrate with AlGaN/GaN transistors, which is a good candidate for next-generation power amplifiers. The microwave noise behavior of GaN-based transistors is also similar to the best GaAs transistors. Thus, the power limiters together with GaN-based LNA will serve as a robust receiver which can be put close to the high-power amplifiers. GaN material systems have been under intense investigation in the last ten years due to its high breakdown field and high temperature operation. GaN transistors operating up to 600C is available in reports from various researchers. The devices and circuits will prove their potential for modern military demand of high power microwave limiters.

Title:Sintered Conductive Adhesives for use in Active Radar System Thermal Management
Abstract:Current Naval microwave power amplifiers operate at power densities around 200-500 W/cm2. Amplifiers under development may operate at 2-4 times this power density. Despite the development of active cooling technologies, the principal technology for removing heat from a chip remains thermal conduction. In most power devices, solders, such as AuSn, are used for die attach bonding. Solder is not adaptable to high volume, low cost processing. There is a critical need from T/R module developers for improvement in the performance of thermally conductive polymeric materials used in electronic packaging. There are few candidate polymeric materials for replacing eutectic solder bonding in electronic devices used in high-temperature environments. Most polymeric electrically conductive adhesives are not capable of long term reliability in such environments. We have demonstrated a low-temperature sintering adhesive that, with modification, will address these performance issues. Based on a novel polymeric resin formulation, they are solvent-free and easily processed. A unique combination of alloy powders in this resin formulation allows the preparation of composite adhesives capable of forming metallurgical connections to suitable metal surfaces. These may be optimized to have electrical and thermal conductivity properties similar to solder materials but with the processing advantages of polymeric adhesives.

Title:Application of Copper-Graphite Composite in Active Radar System Thermal Management
Abstract:Discontinuous pitch-based graphite fiber reinforced copper (Cu/Gr) composites have been under development for semiconductor thermal management. The composites consist of a high thermal conductivity copper-chromium alloy matrix and short pitch-based graphite fibers randomly oriented in planar directions. These composites are a planar isotropic material. The CTE of this composite in planar directions is in the range of 2~9x10-6 /C, varying with the fiber content, to match those of various semiconductor and packaging materials, such as SiC, silicon, GaAs, and GaN, alumina, and AlN. CTE in the through-plane direction is slightly less than that of the matrix alloy. The composites have a thermal conductivity in the through-plane direction from 200 to 320 W/m K and a thermal conductivity in planar directions from 330 to 420 W/m K, also varying with the fiber content. This composite is excellent in terms of machining and brazing, which renders itself as an ideal, low cost thermal management material for high power density packaging of advanced semiconductor devices. In this proposal, a liquid-cooled baseplate of this composite is proposed on which semiconductor modules can be directly built. The ability of this composite to be machined and brazed enables the proposed liquid-cooled baseplate to be cost effective.

Title:Electronic Warfare (EW) System Direction Finding (DF) Interference Suppression
Abstract:As the number and complexity of digitally modulated CW emitters increases on US Navy surface combatants, resolving the problem of suppressing interference to onboard receiver based systems, particularly EW Systems, becomes increasingly important. The proposed solution to this problem, while providing effective relief from the interfering signals, must also be able to be adapted to existing EW systems without degrading the performance of these systems. A novel approach to interference suppression has been developed and patented by Wide Band Systems, Inc. In this approach, the spectra of the omni directional antenna is processed and mixed with the spectra of the DF antenna spectra to provide interference cancellation in both the frequency and angle of arrival processing paths using a single set of filters. The proposed research will determine the feasibility of adapting the approach to the SLQ-32(V) system architecture and perform an analysis to predict the performance and to estimate the impact (if any) to system functionality.

Title:AN/SLQ-32 IFM/CFR upgrade
Abstract:We present several methods for upgrading the AN/SLQ-32 IFM/CFR that are applicable to the subject of the solicitation. The methods address measurement of frequency and pulse-width in the presence of digitally modulated CW interference. We also discuss available technology with which to implement digital processors capable of hosting real-time implementations of practical algorithms based on these methods. The hardware design employs a full-mesh serial backplane for card-to-card data transfers and field programmable gate arrays for most of the real-time signal processing. The architecture of a digital processor takes the form of a parallel processing network specifically tailored to match the natural data flow structure of the algorithm it will host. We propose to analyze the various methods in the context of frequency and pulse-width measurement accuracy, and define an appropriate algorithm for an on-ship Navy system. We propose to then design the hardware platform tailored for this algorithm, and define a Phase II demonstration of the upgraded IFM algorithms running in real-time on that hardware platform.

Title:Fiber Optic/Electrical Lightweight Tow Cable for Optical Towed Arrays
Abstract:Fiber optic towed arrays offer the Navy the ability to deploy larger channel count arrays that support a much wider frequency bandwidth with higher reliability. Without the need for wet end electronics, these arrays also offer lower unit costs and immunity to many electrical and magnetic noise sources. Multiple fiber optic transmission paths are needed in the tow cable to support fiber optic arrays. This SBIR will determine optimum design and placement of the optical fibers within the cable and provide solutions to protect them from the effects of tow cable elongation and strain, thereby ensuring a long working life for the fibers. We will also develop methods to isolate the optical fibers from tow cable vibrations to eliminate phase noise from coupling into the optical telemetry signals. Naval operations in littoral environments dictate the need for lightweight or even neutrally buoyant tow cables, therefore, we will investigate alternative synthetic strength members and select a high performance jacketing material to support handling through compression seals and stowage equipment. Tow cable terminations will also be investigated with emphasis on reliability and low cost. One or more cable designs will be developed that are lightweight, torque balanced, and support electro-optical transmission paths.

Title:Reactive Tungsten Alloy For Inert Warheads
Abstract:Tungsten based alloys (WHA) are commonly used for kinetic energy munitions. However WHA's, both the tungsten and binder components, are generally quite inert and as such their effectiveness is limited to basic lethality of kinetic energy attributes. The purpose of this Phase-I effort is to develop a reactive binder for tungsten particles which effectively augment the lethality by incorporating reactive effects while still preserving the main kinetic energy attributes. The proposed material solution is based on the formulations of amorphous phase Liquidmetalr alloys, which provides extended range of material properties and as such extended flexibility in design. The unique amorphous structure of Liquidmetalr alloys also results in very high flow stress, tailorable density and failure modes, and robust processing and fabrication methods. Various formulations of Liquidmetal alloys will be explored and a candidate formulation will be identified for the optimum reactivity and suitability for composite fabrication. Analysis will be performed to identify an effective precursor composite architecture. The resulting formulation and composite architecture will be utilized to fabricate and test samples in Phase-II.

Title:Reactive Tungsten Alloy For Inert Warheads
Abstract:Physical Sciences Inc. and ATK Thiokol, Inc. propose to develop novel high-density tungsten-based reactive composites for application to inert kinetic energy munitions. These materials will be inert such that they do not reduce the projectile's Insensitive Munitions compliance. Their critical benefit will be to enhance projectile lethality by depositing a combined kinetic and chemical energy in the target, which is greater than the corresponding kinetic energy deposited by a non-reactive tungsten munition. This lethality enhancement will occur over most of the range of anticipated projectile (1300-5000 fps) and payload pellet (2000-6000 fps) velocities. Novel metallurgical fabrication techniques will be applied in these material developments. In Phase I, we shall fabricate samples of two different tungsten metal-oxidizer systems, and characterize their energetic and mechanical properties.

Title:Innovative Non-pyrotechnic Dispersion Device (INDD)
Abstract:Kinetic energy munitions that dispense and disperse pellets prior to impact are effective against threats on the ground or at sea. Typically, explosives or pyrotechnics also contained within the munition are used to impart a lateral velocity to the pellets. Unfortunately, explosives pose a severe injury risk to our military handlers, and impose high shipping costs associated with hazardous material transport (Class A, B, or C). The Navy desires a safer and cheaper dispersion alternative to the explosives in kinetic energy munitions. Mid proposes a dispense and dispersion mechanism that leverages the incredibly high energy density characteristics of Shape Memory Alloys (SMA), and the thermal energy already present in the airframe structure. Strain energy in SMA induced by the high munition temperatures can be harnessed, then transferred to the pellets, providing the required lateral velocity for a wide strike footprint.

Title:Pellet Dispense & Dispersion Mechanism For Inert Kinetic Energy Munitions
Abstract:This effort will develop and evaluate four approaches to dispense and disperse pellets from kinetic energy munitions. The proposed approaches meet the Navy requirement of using either a Division 1.3 (Class B), 1.4 (Class C) explosive, or preferably no explosive at all to dispense and disperse the pellets. They include (a) airbag ejection of the pellets (1.3B); (b) pellet embedment in gas generating pyrotechnics (1.4); (c) contained propellant launch systems (1.4); and (d) aero-mechanical dispersion (no explosive). These concepts include proven existing technology (air bags), previously developed technology [Telecartridge(tm)], and two new ideas owned by Surface Treatment Technologies, Inc.(ST2)The dispersion efficiency, separation velocity, and projected separation profile of pellets will be modeled for the four approaches. Based upon the modeling results, as well as design factors each concept will receive a ranking and recommendation for advancing to Phase II. In the Phase II effort ST2 will fabricate and statically test subscale prototypes of the down selected approach using temperature profiles provided by the customer that simulate aerodynamic loading. Prototype structures will also be delivered to NSWCDD for follow-on testing.

Title:Glint Reduction in Staring Focal Plane Array Mid-Wave Thermal Imagers Employing Microscanning
Abstract:Imaging Sensors and Systems (ISS) manufactures microscanner based Mid Wave Infra-Red (MWIR) thermal imaging systems. MWIR sensors with staring Focal Plane Array (FPA) operating in 3-5 mm are adversely affected by the sun glint in applications where the target must be imaged against a sea-surface background. For this reason ISS has already been working on reducing the sun glint. In this Phase I program, a combination of hardware and software solutions for the glint suppression will be developed and demonstrated. The hardware includes: (a) The microscanner based MWIR thermal imaging system manufactured by ISS, (b) Polarized laser illuminator synchronized with the imaging system microscanner, and (c) Polarizing, spectral band-pass, and temporal filters called Spatio-temporal microscanning technique. The evaluation and demonstration for this Phase I program will also include video processing software for the thermal system. In Initial Phase I program: (1) The concept of an active thermal system will be optimized, (2) Critical components will be fabricated, purchased, and obtained such as the ISS camera Model M320i-3 with microscanner for tests (3) The hardware/software will be assembled for the suppression of the sun glint. This active thermal imaging system concept will be demonstrated in the proposed Option Phase I program.

Title:Glint Reduction in Staring Focal Plane Array Mid-Wave Thermal Imagers Employing Microscanning
Abstract:The problem of efficient clutter suppression is a challenge for shipboard IRST systems that have to provide reliable detection/tracking of cruise missiles in sea glint. In such systems, reliable target tracking is impossible without clutter rejection down to the level of sensor noise. The proposal is geared towards development of novel parametric and nonparametric spatial-temporal techniques for clutter rejection and image stabilization; nonlinear filtering techniques for track-before-detect and tracking; improving performance of the clutter filtering and jitter compensation algorithms; development of a bank of clutter suppression/stabilization filters with outlier compensation and an adaptive, reconfigurable architecture; and testing/demonstrating the capabilities of the developed technology in realistic environments. It is demonstrated that the proposed spatial-temporal methods are particularly efficient for target detection/tracking in difficult scenarios when spatial-only filters completely fail. The developed software imbedded into a GUI interface will constitute a powerful tool for the optimization of operational target detection/tracking systems in conditions of interest. These software tools will be also capable of predicting the performance and reducing to a minimum the time needed to search for an "optimal" system configuration in NAVY programs/systems.

Title:Panoramically Scanned TV/FLIR Imaging Sensor with Target Motion Cueing
Abstract:Current methodology for employing TV or FLIR imaging sensors to search and acquire potential target is work intensive and requires continuous manipulation of complex controls by a highly trained operator. Currently these systems are not optimized and result in a lowered probability of detection and high False Alarm Rates (FAR). Imaging Sensors and Systems, Inc., (ISS) will evaluate (1) Hardware for 360-degree panoramic Field-Of-View (FOV), (2) Intelligent Search Management for Multiple Sensors, and (3) Fusion of EO/IR/RF/Sonar subsystems in the proposed Phase I study. The innovations include Day/Night 360-degree panoramic FOV for targets acquisition, Automatic Target Recognition (ATR) in the large FOV, then a target detection using Foveal FOV, and finally a sensors fusion for the target motion cueing. Thus, the approach will provide automatic search, acquisition, tracking and motion cueing of small targets such as Jet-Skies in water background 360-degree around a ship. System components will be evaluated and analyzed, and then breadboarded in the Initial Phase I study. A panoramically scanned TV/FLIR imaging sensor concept for small cross-section targets will be demonstrated in the Option Phase I program. A brassboard sensor will be fabricated, integrated, and delivered to the customer for evaluations in a Phase II program.

Title:Extended Range Optical Underwater Imaging
Abstract:The Navy needs a compact extended range underwater imaging system that can image through > 6 attenuation lengths with 0.25" resolution. Present systems are limited by scattering to ~ 5 attenuation lengths. To meet the need, we propose a compact, adaptive raster scanner, using a doubled Yb fiber laser for the transmitter, a wide field-of-view (FOV) receiver, and an annular APD detector array, enabling adaptive data processing. The fiber laser offers excellent packaging, robustness, and output characteristics for improved S/N. The receiver offers improved collection efficiency, and the annular array adaptively balances S/N and resolution needs. The proposed system is estimated to have two decades more dynamic range than current imaging systems. Phase I is a design study on the proposed system. Optical design, together with Monte Carlo modeling simulations for various underwater scenarios, yields an optimal optical layout, and analyses of the efficiencies, S/N and resolution capabilities. We develop a preliminary packaging concept for a small underwater vehicle, together with size and weight estimates. In the Option, we define the electronics and interfaces, and develop a power budget for the complete system. The Phase I preliminary design leads to detailed design and construction of a prototype in Phase II.

Title:Extended Range Optical Underwater Imaging
Abstract:Underwater laser line imaging systems in the past were designed and built to provide the best performance possible using the technology available at the time. Typically these designs have either emphasized range-gated or synchronous scanning technology to reduce scatter, i.e., using time-of-flight characteristics or the geometrical configuration between source and receiver. Only recently has technology reached a level where both approaches may be combined to provide improved performance in terms of image quality and component reliability. The system proposed here uses a range-gated narrow and collimated laser beam that is coaxially tracked by a high speed detector. The design provides extended range imaging with the ability to reduce forward and backscatter, and has a small form factor requiring low power. The coaxial configuration also eliminates source-receiver alignment issues so that a more rugged instrument requiring only a single scanning component may be required. This design should achieve a new threshold in underwater imaging quality that is readily deployable from a variety of platforms.

Title:Development of large bulk Silicon Carbide substrates from halogenated precursors
Abstract:The development of long SiC boules grown from the gas-phase using chlorinated halo-hydrocarbons faces enormous technical hurdles that must be overcome. The hurdles of specific interest are the outlet, the materials degradation, the inlet, and thermal issues. Caracal proposes to find a solution to all of the above mentioned technical obstacles. The outlet is of particular importance since it limits the length of the boules to 2 - 5 mm. Caracal suggests an outlet which can keep a free path for the gas for prolonged growth yielding longer than 75 mm crystals. The inlet needs more development in order to handle the long growth times required. The graphite materials and insulation has historically caused drift in the system due to reactions with silicon vapor and hydrogen. Caracal proposes new crucible material that can withstand these attacks much better. Finally, in order to keep the growth conditions constant, the growing crystal must be pulled upwards into a cooler area which will cause a change in the thermal profile. Heat must be added to the top of the chamber in order to keep the system constant. Caracal will analyze and model the thermal conditions and propose a solution to this.

Title:Development of Large Bulk Silicon Carbide Substrates From Halogenated Precursors
Abstract:INTRINSIC proposes bulk SiC single crystal growth via halogenated precursors for growing ultrahigh quality SiC materials. This is a unique approach which will provide benchmark SiC substrates in WBG technology. The technical objective of the Phase I program is to demonstrate the growth of ultra-high quality SiC crystals at relatively lower temperatures than the mainstream PVT growth technique by using the halogenated gas sources for Si and C. With the proposed approach, the state of the art semiconductor process controls will be utilized for the SiC bulk growth which are not available in mainstream PVT technology today. Due to the high purity of the gases used and the improved precursor controls, it is possible to grow very high purity SiC and control defect formation. This approach will be capable of producing doped SiC crystal of different polytypes, both n-type and p-type conductivity, as well as insulating which are necessary properties for high-frequency and high-power applications.

Title:Vision-Based Obstacle Avoidance Using Active Scene Segmentation
Abstract:Successful operation of autonomous flight systems in uncertain environments is currently limited by the lack of practical obstacle avoidance systems. In the proposed effort, we shall exploit recent and on-going advances in the fields of image processing, estimation, real-time path planning, and guidance/control to demonstrate successful flight through a cluttered and uncertain 3-D urban environment using simple imaging sensors and appropriate custom-developed processing hardware. In particular, we propose the innovative use of variational methods to dynamically segment scenes, leading to a fast and natural approach to estimating the location of unknown 3-D obstacles. During phase I the feasibility of real-time algorithm execution will be established using current generation processors, and robustness to transient sensor data, distortion, and obscuration evaluated. A systems engineering analysis will be used to fully characterize system performance as it relates to a variety of design parameters and constraints. In phase II, efficient means to produce the appropriate level of image understanding required for successful operations will be further developed, the algorithms will be fully realized in hardware and software, and the prototype system will be fully evaluated in UAV flight operations over urban terrain.

Title:See and Avoid Fly Eye Sensor System for Autonomous Air Vehicles
Abstract:Physical Optics Corporation (POC) proposes to develop a novel See and Avoid Fly Eye (SAFE) 3D-image-based proximity and flow sensor system that will enable an autonomous air vehicle (AAV) to automatically avoid colliding with obstacles, enabling it to carry out missions autonomously in urban and confined environments. The SAFE sensor system combines a miniature staring multi-aperture compound eye (fly eye) with a low-cost CMOS smart vision sensor chip that consists of a compact miniature photodetector array and a neural network processor for high angular resolution and large field-of-view. Digital signal processing and a simple neural network support real-time flight path optimization for collision avoidance. This unique combination results in a high-speed and high-performance system that ideally matches the stringent cost, size, weight, and power requirements of small-scale autonomous air vehicles. The Phase I work will include the development and implementation of the SAFE system approach, and a demonstration of its collision avoidance performance to prove the feasibility of the concept. Phase II efforts will include system optimization, culminating in a full prototype built, field tested, and analyzed to confirm the suitability of SAFE for military and commercial applications.

Title:Electromagnetic Design Techniques Enabling Control of the RFID Supply Chain
Abstract:Wavelet Technologies, Inc. proposes development and application of electromagnetic design techniques for RFID tags that will make RFID tag design "component agnostic", that is the lowest priced available components can be used in a system meeting desired system performance. This guarantees that RFID tag components, such as RFID chips, can always be acquired on competitive bids at the lowest possible unit prices. Component agnostic design requires technical flexibility because of the large number of possible combinations of antenna materials, tag substrates, chip impedances, etc. as well as the effects of antenna loading by product packaging and other environmental effects. We show that this large number of possibilities can be accommodated by genetic algorithm based design techniques that optimize antenna geometries to particular RFID chip impedances and accommodate various materials properties of the antenna, substrate, and electromagnetic environment of the RFID tag. RFID tag designs can be accumulated in a database for future reference. The combinatoric explosion of RFID design parameters is addressable by cluster computation using commodity PCs, giving a cost-effective, scalable implementation path. A business case model is presented showing how component agnostic design can minimize component outlays when multiple parts vendors are present.

Title:Performance Enhancement System for Long Thin Unreliable Intermittent Pipes
Abstract:The Navy is seeking to transparently incorporate advanced communications techniques suitable to increase the efficiency of the current RF and Microwave communication system. Specifically, a modularized and extensible system is required for Long, Thin, Unreliable and Intermittent pipes such as narrow and medium band satellite and bandwidth constrained intermittent RF links. Internetworking protocols require proper augmentation and correction due to long feedback loops, large number of in-transit packets, transmission errors, asymmetric links and intermittent connectivity. A plug-n-play, non-supervised performance enhancement software solution is incorporated into legacy systems to overcome these problems. It is well noted in many research literature that a majority of problems in long delay wireless networks either stem from sensing or measurement, inefficiency or can be better overcome if accurate sensing were available. To address this problem, Broadata Communications, Inc. (BCI), leveraging its networking protocol expertise, proposes to develop a Generic Network Measurement Software Architecture (MSA). The MSA is an innovative modularized architecture that transparently achieves accurate network monitoring and measurement and facilitates the positive enhancement of network performance.

Abstract:The impact of Improvised Explosive Devices (IEDs) is devastating for US and allied troops dealing with this threat on a daily basis. The proposed technology deals with a method to identify from a safe distance, the detonation wires attached to these IEDs so that evasive action can be taken. A sensor mounted on a UAV will rapidly allow large roadside areas to be searched in real-time, thereby allowing the convoy to proceed in relative safety. The UAV will travel with the convoy, relaying additional information about the location and visible appearance of the IED from the air as verification. This proposal will miniaturize the sensor technology and integrate it with existing UAV ground stations and C4 systems. This development effort will result in a demonstration in theatre, of a UAV mounted sensor which will identify IED detonation wires, thereby providing additional protection to troops deployed in hostile areas.

Abstract:We propose to develop an optical Improvised Explosive Device (IED) activity detection system that is designed for military applications. The purpose of the Phase I program is to demonstrate the feasibility of our proposed approach. The proposed system is intended to detect tampering with or disturbance of pre-treated areas that are prone to IED deployment. After pre-treatment, optical Images of the target areas will be captured and analyzed to determine if there has been IED related activity. The proposed system can be configured to be carried on a moving vehicle or held by hand. On a vehicle, the detection system will be scanned in order to interrogate a wide target area. The system will function at night and in broad daylight. At the center of our approach is a fluorescent material that will be dispersed over target areas. A filtered, intensified optical detection system will be used to image fluorescence from pre-treated areas and to monitor changes that signal IED deployment. Emphasis for the Phase I program will be on the development of suitable fluorescent materials and on the construction of a breadboard demonstration for proof-of-concept.

Title:Technologies to Defeat Improvised Explosive Devices (IED's)
Abstract:"Cognitive Detection" for a Rapidly Deployable "In Vehicle" IED Detection System "Cognitive Detection" uses a soldier's normal vision acuity to "automatically" detect IED's. It will dramatically enhance the detection of changes of "before and now" images in an easy to compare format. For3d uses off the shelf GPS technology to render a reference view from a (Pre IED placement) database that is nearly identical to the current camera vehicle " view". Both views are presented on a single display for immediate comparison in a manner that significantly enhances the soldier's natural ability to detect a new surface feature. Cognitive Detection can identify recent changes immediately as the convoy is in transit (not several hours after an assessment sweep has been made). Benefits 1) User friendly 2) Easy to deploy and 3) Economically viable 4) Works at night with a thermal sensor 5) Minimal false positives 6) Provision for updatable surface information based on "last acqusition" 7) Range of reference sensor/camera inputs (aerial, thermal, video, or multi spectral sensors) 8) Uses Off the shelf GPS, Tough Book, and consumer video cameras The relative simplicity and cost of this system offers a very near term solution.

Title:EXPLOSIVE DETECTOR FOR RAPID SITE SEARCH
Abstract:Menon and Associates, Inc. proposes to develop a new explosive-detection system. The system will support site searches by enabling rapid collection and analysis of particulate samples, revealing prior explosive handling in the area. The system will thus reveal clandestine preparation sites for explosive devices such as IED's, car bombs, and suicide belts as well as ordnance rework, arms storage, and any other activity which generates particulate residue of explosive material. The proposed system includes a sample collection unit and an analysis unit. The collection unit is a hand-held vacuum-type evidence collector, which deposits sample material in special filtered vials. The analysis unit is based on the MENTOR (Mobile Environmental Threat Detector), a miniature magnetic resonance (MR) instrument to analyze characteristic explosive signals within the collected material. Prototype tests have demonstrated high detection probability for small quantities of explosives. Modifications of the prototype system have also demonstrated high sensitivity for chemical/biological weapons and their precursors. In Phase I we plan to test nitrogen-detection upgrades and test the hand-vac technique with filter vials. In Phase II we will field-test a fully functional unit and initiate a rapid manufacturing program.

Title:Technologies to Defeat Improvised Explosive Devices (IED's)
Abstract:In this Phase I SBIR Proposal, Nanotherapeutics, Inc. proposes to demonstrate the improved proximity detection of hexamethylene triperoxidediamine (HMTD) and triacetone triperoxide (TATP) explosives using its proprietary NanobreathTM preconcentrator and 4-SAW array. The NanobreathTM 4-SAW Array, a novel, portable, rapid gas chromotography (GC) system, currently being developed for medical testing and diagnosis, will be evaluated for the rapid detection of Improvised Explosive Devices (IED's) at safe distances. While most conventional explosives detectors rely on the presence of nitrogen groups in the explosive molecule to obtain a positive response, non-nitrogen containing HMTD and TATP peroxide explosives present a serious challenge to detection and neutralization by counter-terrorism and security forces. Nanotherapeutics proposes to (1) evaluate different concentrations of HMTD and TATP in ambient air, (2) evaluate different preconcentrator adsorbant materials and air collection volumes for proximity sampling, and (3) evaluate different chemoselective polymer coatings on surface acoustic wave (SAW) sensors to measure the linear response range and limit of detection (LOD). It is proposed to demonstrate the feasibility of the NanobreathTM system for improved proximity detection in the Phase I Project towards the development of a robust commercializable explosive detection system in the Phase II Project.

Title:Field Collection and Analysis of Forensics and Biometric Evidence Associated with IEDs
Abstract:Nomadics proposes to implement its proven Fido explosives detection system to produce a system specifically designed to identify the trace chemical signature of explosives on personnel who may be involved in the fabrication or transport of improvised explosive devices (IEDs), including suicide bombs. The system can further be used for forensic purposes in connecting detected explosives to specific individuals or incident sites. Studies have shown that persons handling explosives become contaminated with molecular residues of the chemical. This contamination is likely to be found on their clothing and on their person. The residues are very difficult to remove, and for highly sensitive sensors such as Nomadics Fido may be present in detectable quantities for hours or even days after the subject handled the explosives. Through simple transfer methods and the analysis of readily available samples, Fido under the proposed concept will serve as a valuable tool in locating and identifying persons involved in fabricating and transporting IEDs and in providing evidentiary forensics support in the apprehension and prosecution of those persons. The advanced status of Fido-though new to this application-will allow Nomadics to move quickly to proof-of-concept and rapid progress toward the acquisition and deployment phase.

Abstract:All explosive devices, including IEDs, have chemical signatures that to date have been underexploited as a means of detction. Nomadics is proposing to employ chemical sensing methods to determine if suspected items contain explosive elements or not. Using the Fido ultra-trace detector as the core sensing element, Nomadics will integrate the sensor onto small robotic vehicles such as the USMC Dragon Runner. This work draws upon earlier tests that have demonstrated the ability of the Fido sensor to detect the explosives vapors given off by IEDs.

Title:Antenna Polarimetric Imaging Sensor to Detect IEDs
Abstract:We propose to develop a dense micro antenna focal plane array (FPA) sensor for imaging polarized infrared (IR) emitted by man-made IEDs, emitting IR having a distinct polarization discriminating them from the randomly-polarized IR emitted by the natural background. Each pixel of this FPA consists of two micro dipole antennas disposed orthogonally to each other to detect two planar polarized LWIR. The signals from these are read out independently so that they can be summed vectorially to maximize contrast irrespective of the direction of polarization of the IR emitted by the IED, identifying it with little post-sensor data processing. The entire FPA is processed by CMOS (complementary metal oxide semiconductor) and MEMS (micro electro-mechanical system) processes. Phase 1 will design the FPA structure and layout, delineate the processes for fabrication and fabricate a simple structure to demonstrate its fabricability.

Title:Roadside Explosive Device X-Ray Detecting System
Abstract:The Marine Corps needs an instrument that can detect roadside improvised explosive devices (IEDs), which continue to threaten U.S. forces as they conduct overseas operations. The system should be mounted on a small, remotely operated vehicle (ROV) or a man-operate vehicle, or should be man-portable; so that it can detect concealed IEDs, even through metal. Existing backscatter imaging sensors for detecting explosive devices take a truck to transport, are expensive, and above all are hazardous. To meet this need, Physical Optics Corporation (POC) proposes to develop a new Roadside Explosive Device X-ray (REX) Detecting System that focuses hard X-rays to discriminate IEDs from similar objects. REX can examine suspect roadside objects from all points of view, recovering full 360 degrees imagery of potential IEDs in real time. The proposed REX system images IEDs and other hidden objects by means of Compton backscattering. It will operate in the X-ray energy range from 40 to 80 keV. The REX system has high resolution and high signal-to-noise ratio because of its true focusing capabilities. In Phase I POC will develop a preliminary proof-of-concept prototype of the REX system. In Phase II, a preproduction REX system will be fabricated and tested.

Abstract:Improvised explosive devices (IEDs) threaten US forces as they conduct overseas operations. Recent attacks in passenger trains have also signified the need to have portable and low cost explosive detection devices. The proposed sensor approach address this need by providing low cost and portable but highly sensitive and selective method of detecting explosive vapors. The detectors are based on a micro sensor technology which has already been proven as portable, sensitive and rugged vapor detectors. The novel approach proposed further improves the sensitivity and selectivity for explosive vapors. The sensor hardware and control software already available in commercial devices can be adopted for prototype fabrication.

Title:Anti-Rocket Propelled Grenade (RPG) Technologies
Abstract:Since the Vietnam War, military forces of the United States have had to contend with a highly effective and lethal weapon originally developed by the Russians as a shoulder-mounted rocket propelled grenade designated the RPG-7. The weapon was licensed for manufacture to allies and clients of the Soviet Union. Subsequently, the RPG-7 became the weapon of choice by insurgents and terrorists around the world. A family of warheads now exists to engage a variety of targets. Few countermeasures have met with success. One method that achieved some success in Vietnam was placing metal mesh fencing as a skirt around U.S. military vehicles to intercept incoming RPGs providing stand-off detonation or causing the grenade's metal ogive to bend contacting the warhead's inner cone, shorting the arming signal and causing the grenade to dud. The active defense system proposed borrows conceptually from that countermeasure. Following launch detection, the approach is to intercept the RPG with a net mounted on an umbrella-like frame fired from a canister on the vehicle. The objective of the net is to ensnare the RPG's fins, disrupting their flight stabilizing effect and deflecting the RPG's trajectory, turning its shaped charge away from the target.

Title:Light-Weight Ballistic Armor for Military Vehicles
Abstract:The current conflict in Iraq has revealed a vulnerability of lightly armored military vehicles to attack and destruction by rocket-propelled grenades (RPGs). Recent research under ONR sponsorship, led largely by investigators of this proposal, has already revealed that dramatic improvements in blast resistance can be made by exploiting periodic cellular metal sandwich panel concepts. Separately, concepts that integrate stochastic aluminum foams into armor systems have shown promising potential for improved ballistic resistance. The proposed program will focus on the development of sandwich panel technologies that integrate blast and ballistic protection into a single panel. Dynamic finite element simulations will be performed of the interactions between projectiles and the targeted metal/ceramic structures for the purpose of identifying the material combinations and topologies that exhibit the best potential for ballistic resistance. Several prototypical metal/ceramic sandwich structures will be fabricated, using existing manufacturing and bonding procedures. Initial ballistic testing of prototype panels will be conducted and compared against the predictions made by the models to establish fidelity. The objective of the activity is to develop cost-effective, lightweight armor systems, based on sandwich panel construction, for blast and ballistic loadings that could be used to protect existing military vehicles.

Title:Fluidic Counter-Jet Armor
Abstract:The use of fluid counter-jets to disrupt the axial symmetry of armor piercing shaped charge warhead jets was demonstrated during the last century, but the research was limited in its scope to large cross-sections. The mass and bulk of these cross-sections restricted their suitability for fielding and the work terminated. Ceramic Composites proposes to expand upon the prior work, utilizing select portions of the previous findings to create a new armor system that increases the formation of the fluidic counter-jet in a lightweight armor system. The system is envisioned as a retrofit to existing armored personnel transport systems which can be readily produced from conventional materials. In the proposal, the theories and findings of the earlier work to support the concept are presented. During the subsequent program, demonstration samples will be fabricated and provided to the Navy for testing and evaluation. The goal is to verify the performance of the functional theories, followed by an analytical and design optimization analysis in Phase II, concurrent with manufacturing scale-up to produce prototype sized components.

Title:Anti-Ballistic Airbag for RPGs
Abstract:This proposal describes a protective system for military vehicles that can prevent (or mitigate) damage caused by incoming Rocket Propelled Grenades (RPGs). The system is applied to existing vehicles, and can be removed and reattached with a minimum of effort. A key advantage of this protective system, called Anti-Ballistic Airbag (ABA), is that it pushes the explosive energy of the RPG away from the vehicle, preventing the typical loss of life and severe vehicle damage caused by a RPG. Our concept, consisting of a rapidly inflating protective Kevlar-type bag, is the analog of the automotive airbag, which has been extremely successful at protecting vehicle passengers from severe injury in a vehicle crash. In the same way, the ABA makes use of the known timing and physics of an RPG to deploy a protective bag before it strikes the vehicle. The ABA is placed on the outside of the vehicle and can be deployed before the RPG strikes the vehicle and explodes.

Abstract:The FIRST RF team proposes a system that will provide RPG launch warning and bearing determination. The proposed system will be mounted on top of a vehicle or installed on fixed sights. The intent is to keep the system simple and affordable to allow integration on a wide range of platforms and users. Even a limited number of installations will provide a limited yet effective shield by detection of RPG threats. An important feature of the system is that it is rugged and reliable. The key element of the proposed system is a Ku-Band radar with an affordable antenna system that detects an incoming RPG. The dynamics of the system allow detection of rounds as close as 150 meters to ranges greater than 1000 meters. An optional optical system is proposed to augment the radar. The overall objective of the proposed Phase I effort is to demonstrate feasibility of the omni-sensor system for the anti-RPG application. Laboratory tests will be conducted to validate key components such as the RF aperture. A full system model will be generated to demonstrate effectiveness of the proposed concept.

Title:"Hurricane" Anti-Rocket Propelled (RPG) Technologies
Abstract:Foster-Miller's proprietary nets (FMNETS) have consistently defeated the RPG-7 threat in Government sponsored live tests over engagement speeds of 25 through 100 m/s. Specifically, the ultra-lightweight barrier defeated the RPG-7 by collapsing the ogive, shorting the fuze, and dudding the round. Implementing an effective delivery mechanism for the proprietary RPG barrier to support close-in ground vehicle protection is proposed. The system is called Hurricane. Hurricane implementation is practical and economical. Proposed in a `pill-box' form factor and mounted on a vehicle's roof rack, the weight of a system possessing full side coverage is ~35 lb. Hurricane can be installed by one person as needed in under 20 min and can be reloaded in 1 min. The package is modular and can be tailored to any vehicle covering any side or top and is readily integrated to a sensor/fire control system of user choosing. Delivery of the FMNET can be designed to intercept the RPG while the FMNET is moving at peak velocity perpendicular to the RPG flight vector. The resultant side force, equivalent to a Hurricane gust, has the potential of both dudding and rapidly turning the RPG sideways. The resulting defeat minimizes follow-on impact against the host vehicle. (P-040476)

Title:Multi-Modal Wide Field of View Weapons Detection System
Abstract:Genex Technologies, Inc. proposes in this SBIR effort to develop and test the feasibility of a novel multi-modal weapons detection sensor system that reliably detects and locates Rocket Propelled Grenades (RPGs) in wide field of views (FOVs) (up to 360,a) and automatically performs countermeasures. RPGs represent a continuing threat against our troops in Iraq and around the world. Their relative low cost and availability makes them an attractive weapon to terrorists who threaten our troops. To combat this terrible threat, Genex proposes a novel, omni-directional image/acoustic surveillance sensor with reliable accuracy in locating the source of the RPG with a low false alarm rate and in real time. Current solutions, such as purely acoustic technologies that detect an RPG launch and its bearing, have proven unreliable with a high incidence of false alarms and slow response rate. When a weapon is fired, the chemical in the propellant causes a unique signature in the spectrum. We will investigate spatial and temporal methods to detect the spectral signature, determine whether it is from a weapon and what type of weapon it is by its unique spectral signature, and combine this imaging solution with acoustic detection to improve accuracy and reliability.

Title:Anti-Rocket Propelled Grenade (RPG) Technologies
Abstract:The availability and use of the Rocket Propelled Grenade (RPG) systems for hit and run ambushes has placed US and allied forces in a vulnerable position while trying to conduct peacekeeping operations. For combat units, the necessity to minimize collateral damage, prevent harm to noncombatants, and still defeat the threat does not allow for normal combat drills. Additional problems occur for service and support units, which are extremely vulnerable to attack due to the lack of armor protection and firepower. Finally, static positions and bases are also vulnerable to RPG attacks, either in the direct fire or indirect fire mode. HEM Technologies and Texas Tech University intend to exploit possible RPG vulnerability to electromagnetic radiation in order to destroy/neutralize the RPG. We propose to use a burst of directed electromagnetic pulses to establish an electromagnetic barrier to destroy/neutralize the warhead while in flight. It also has potential excellent carryover use against other threats such as Improvised Explosive Devices (IED's) and could provide standoff protection for Explosive Ordinance units or for clearing a room or building of booby traps. Commercialization of the device is possible in any demolition or mining activity as an alternate means of detonation.

Title:Anti-Rocket Propelled Grenade (RPG) Technologies
Abstract:The inexpensive RPG has caused havoc with US armored vehicles since WWII. Therefore, MSI has conceived of an active protection system that consists of six evenly spaced stationary horizontal gun tubes, able to shoot projectiles containing thousands of tungsten balls toward an RPG firing, as detected by infrared sensors between gun tubes. The frangible ogive that contains the balls is designed to split upon launch, such that dispersion of the balls will cover the side of the vehicle that the RPG is launched against, but without allowing gaps between the balls as large as the RPG. The 1/8 inch diameter balls are of a mass and relative velocity (based primarily on the velocity of the RPG, with the ball velocity as margin) that the kinetic energy from even a glancing blow will trigger the RPG piezoelectric fuze, causing the shaped charge to fire and dissipate before it can penetrate the vehicle's armor surface. The tungsten ball projectiles will be fired in pairs (each tube on each side of the triggered sensor) to maximize hit probability. The clips which hold four projectiles each would be capable of up to four successive firings before reloading of that clip would be required.

Title:Anti-Rocket Propelled Grenade (RPG) Technologies
Abstract:During recent military actions in both Afghanistan and Iraq, a serious and deadly threat to US forces, and in particular convoys, has emerged. Chief among these is the Rocket Propelled Grenade (RPG), which is causing significant casualties to US personnel and disrupting allied operations. RPG's are difficult to defeat because conventional jamming techniques are ineffective against unguided munitions, and the distances from which they are launched result in very short windows of opportunity. The proposed Anti-RPG SBIR concept is to employ Metal StormT technology as the means of applying effective firepower against the threat, aimed and controlled by Northrop Grumman's threat identification and fire control technologies. The Metal StormT concept utilizes multiple barrels in a variety of effective configurations with multiple projectiles per barrel, and electronic firing with no moving parts to achieve extremely high rates of fire over short periods of time. The precision of this firepower is achieved by proper integration of the Metal StormT aiming pods with Northrop Grumman's proven target acquisition and tracking systems. A wide variety of options in Metal StormT munitions and Northrop Grumman control systems allows tailoring of the designs for optimum performance.

Title:Novel Armor Counter-RPG Systems
Abstract:By mechanically attacking the nose/warhead of a rocket-propelled grenade (RPG), one can render the RPG into a purely kinetic projectile rather than an explosive one. This can be achieved by shearing the nose fuze, collapsing the ogive, or disrupting the explosive itself. While a 2.5 kg projectile at up to 300 m/s is a sizeable kinetic projectile, it can be defeated by the armor of Stryker and Bradley vehicles as well as other vehicles with add on armor packs. Such packs are typically capable of defeating the shaped charge itself, so augmentation is required. Nomadics has been funded by DARPA to explore a concept called Iron Curtain that uses automatically fired projectiles to defeat RPGs. However, in the course of this work, we have devised other strategies that have the potential to defeat RPGs. In the proposed effort, we will investigate these concepts, which involve passive and semi-passive methods. Based on discussions with the sponsor and experiments conducted under this project, we will assess the effectiveness of these concepts and make recommendations for continued development of the more promising. This furtherance of the effort beyond proof-of-concept would be the subject of Phase II.

Abstract:Under funding from DARPA, Nomadics has demonstrated the potential for deploying multi-gun fixtures as a means of defeating rocket-propelled grenades (RPGs). These early tests have created a database that will be invaluable in advancing the work toward optimization of the initial concept through enhancements in both the gun fixture and the projectiles as well as in the defeat strategies based on this approach. Under the currently proposed work, we will focus on optimization of the projectiles. By designing novel projectiles one can increase the probability of disrupting the warhead of an RPG or destroy the fuzing system such that the warhead does not high order. During Phase I, optimization enhancements will be demonstrated to show that these early prototypes should be further refined in Phase II. Nomadics' initial work in this area as well as the company's rapid prototyping efforts will help to ensure that the envisioned system moves quickly toward acquisition and deployment to meet this urgent need.

The current weapon was licensed to allies of the Soviet Union, and subsequent to its fall, the RPG-7 became the weapon of choice of insurgents and terrorists around the world. A family of warheads now exists to engage a variety of targets. Few countermeasures have met with success. Since some RPG's shaped-charge warhead is capable of penetrating 12 inches of armor plate, few mobile barriers can shield the personnel from its lethality in the case of a perfect hit. To reduce the lethality of these weapons, the countermeasure proposed here is to deploy specially designed airbags to modify the RPG's hit geometry, to serve as blast barriers absorbing the blast pressure and shrapnel, and to provide detonation separation which also reduces RPG potency. The proposed approach is part of an Active RPG-Defense System (ARPGDS) concept that builds on relatively mature technologies to enhance the survivability of the vehicles and the occupants inside.

Ultrasonic Consolidation is a solid state, additive manufacturing process that produces fully dense metal laminates. UC features that make it a high potential technology for in theater retrofitable armor include 1. Energy absorption through anisotropic, laminar structures 2. Ability to incorporate multiple monolithic and composite materials for improved ballistic performance 3. Ability to insert single or multiple ceramic layers 4. Can be applied to existing vehicles and structures 5. Sensors such as optical fibers, antennas etc., can be embedded in armor to determine the extent and location of damage 6. It may be possible to produce reactive armor with multiple repeating capability using this technique due to the low temperature, solid state manufacturing process Background on the technical aspects of the UC process is provided to illustrate the broad significance and potential for this process in armor applications, followed by the Technical Objectives and Phase I Work Plan.

Title:Anit-ballisitc/Anti-RPG Window Armor Made with 7 Times the Impact Strength of Lexan
Abstract:CBDO copolymers and nanocomposites are revolutionary transparent polymer armor materials with 7 times the notched Izod impact strength of Lexan. Using these materials in armor laminates will result in windshield/window structures with superior anti-ballistic/anti-RPG performance at commodity plastic pricing. Windshield armor laminates are proposed that use CBDO based high impact plies interleaved with state-of-the-art energy absorbing and blast resistant polyurethane plies. These laminates will be designed into Kevlar framed quick attachment windshields/windows for current military vehicles. The stated Phase I goals are to pass NIJ Level III (7.62 mm NATO round) with a 20% thinner laminate and V50 fragmentation simulating projectile (FSP) velocities 20% higher than current transparent armor, with further improvement in Phase II. Pilot production manufacture via OEM is identified and bids received for Phase II. CBDO copolymer/nanocomposite armor resins in pelletized format - ready for sheet molding and laminate formation - are the ultimate SMRC product goal, and demonstration CBDO based armor for windshield/window replacement will be tested in Phase I/II test articles and prototypes. Two transparent armor manufacturers with military vehicle experience are signed on to help develop this new armor technology, providing test and vehicle integration expertise, and they are early licensing targets for Phase III.

Abstract:TPL believes that it can detonate an RPG in flight and after its setback switch has been armed. The destructive effects of shrapnel on an armored surface of should be significantly reduced or eliminated. As compared to the destructive effects that develop when the RPG shape charge is detonated at a specified distance from an armored surface. The RPG setback switch is armed approximately 25 meters from the launch site, this event occurs after both the main thrust rocket and radial jets have been ignited.

Title:Novel Vehicle Self-Protection System(1000-540)
Abstract:Triton Systems Inc. (TSI) proposes to develop a modular vehicle self-protection system aimed at countering the RPG and ATGM threats recently presented such extreme dangers to US Army and USMC thin-skinned vehicles. The developed system will be suitable for a wide range of US vehicles, ranging from the HMMWV to light armored vehicles (current APCs, Stryker, FCS). The TSI configuration for a vehicle self-protection system builds on the basic concept fielded in the Soviet "Arena KAZT", but modifies the counterfire launcher and lethality mechanisms. A number of these launchers will be emplaced on the vehicle to provide as nearly 2p coverage as possible. The self-protection system will not require slewing or elevation training, but only fuzing of the appropriate launcher in the threatened zone. During the Phase I TSI will perform engagement tradeoffs to define timelines, coverage limits, and discretization of the 2p threat envelope. We will identify threat RPG/ATGM kill thresholds to determine required pattern densities and KE levels. TSI will develop CAD models of the system and its components. We will fabricate kill projectiles and fire several at achievable velocities verifying lethality. We will finally identify Phase II development partner(s) for threat sensing and fire control elements.

Title:Anti-Rocket Propelled Grenade (RPG) Technologies
Abstract:The StunStrike IOD (Incoming Ordnance Detonator) would be tuned to pre-detonate and RPG by stimulating the piezo-electric crystals used in the detonator through a high-frequency, high voltage electrical pulse from a tuned, artificial lightning spark. The effect of the spark would also transmit through the housing of the RPG to detonate the explosive itself. In addition, the RF generated by the directionalized plasma field could be enough to resonate the piezo-electric crystals sufficiently to pre-detonate the device well before it came within spark range. The ability to use a directed-energy approach like this would create a virtual "force field" around US assets in RPG-rich environments.

Title:Reactive Fiber-Reinforced Composite Materials
Abstract:We propose to develop reactive composite materials with sufficient strength and stiffness to serve as warhead fragments and structural missile components. The materials will be composed of an active metal, such as aluminum, in the form of wire or wire-mesh, within a bonding matrix of an oxidizer-rich polymer, such as PTFE. The result will be a fiber-reinforced composite material with substantial strength and stiffness properties that can be tailored to specific applications, while providing significant thermal energy release in impacts and explosions. This energy will provide increased lethality, especially in neutralizing explosive-containing munitions and missiles. Various material systems and fabrication techniques will be investigated.

Title:Anti-Mortar, Anti-Rockets, Anti-Missile Technologies
Abstract:With the growing number of hit and run attacks mounted against U.S. interests by individuals using mortars and rockets, and with the growing threat of missile attack on aircraft, both civilian and military, a fast response lethal defense system is required to identify, engage and destroy mortars, rockets and missiles while in flight. General Sciences, Inc. proposes to develop and demonstrate a new payload compatible with the Full Spectrum Active Protection Close-In Layered Shield system, also know as FCLAS, and a specific version of the FCLAS system known as the XM8 Programmable Grenade Launcher (PGL), developed by Archangel Defense Systems, Inc., Washington, D.C., and Chang Industries, California for TARDEC, the Tank-Automotive Research, Development and Engineering Center, a division of TACOM, located in Detroit Arsenal, Warren, MI. The FCLAS XM8 PGL can be fielded to existing tactical vehicles, is flexible in use, and has millisecond response times. The new payload will consist of discrete projectiles fabricated from reactive materials, designed to give orders of magnitude higher lethality compared to inert steel, given a hit on target. By using a high explosive initiation, a pressure field will be generated in the path of the incoming threat, along with many reactive projectiles. The pressure field will serve to slow the threat figure and allow the reactive projectiles to impact, initiate and reactively destroy the threat figure through a thermobaric event, an event which can enhance temperature/pressure impulses and cause higher levels of target damage. The reaction will produce high temperatures and localized pressure fields, causing the rupture and destruction of the incoming threat.

Title:Fly Eye Sensor for Countering Rocket and Mortar/Missile Attacks
Abstract:To address U.S. Marine Corps need to counter mortar, rocket, and missile attacks against U.S. forces, Physical Optics Corporation (POC) proposes to develop a new high-speed electro-optical sensor system based on the visual system of the fly. The proposed Sensor for Countering Rocket and Mortar/Missile (SCRAM) attacks uniquely combines a miniature staring multi-aperature compound eye (fly eye), with a low-cost smart vision sensor chip that consists of a compact miniature photodiode array and a neural-network processor. Initially SCRAM will perform high-speed moving-object detection and warning of the incoming projectiles over a wide (~180 degree) hemispherical field-of-view (FOV) without any moving part. SCRAM will also continuously track the location and direction of the projectile, showing the projectile's impact and launch points. The unique architecture results in a high-speed and high-performance system that ideally matches the stringent speed, robustness, size, weight, and power requirements of hostile environments. In Phase I, POC will design the SCRAM system to demonstrate the feasibility of the proposed approach in a laboratory setting by means of a breadboard setup. In Phase II we will optimize the design and develop an engineering prototype to be demonstrated and performance evaluated in simulated encounters.

Title:Anti-Mortar, Anti-Rockets, Anti-Missile Technologies
Abstract:Mortar, rocket, and missile attacks continue to constitute a threat to fixed locations associated with US operational forces. Sensis Corporation offers an innovative approach for adapting an existing interleaved slotted waveguide Ku Band phased array antenna for rapid detection and location of enemy mortar and artillery fire. The concept can be extended to address missiles. The proposed Ku-Band phased antenna features lightweight, structurally rigid waveguide, but with a patented technique for achieving dual-axis monopulse using interleaved slotted waveguide (ISWG) pairs. This unique feature is a departure from conventional arrays (e.g., AN/TPQ-36), and is essential to achieving operationally effective launch-impact CEP accuracy. The subsystems required, in addition to the antenna, for a fully compliant Ku-Band radar design are available as Sensis products, or as COTS items. The proposed design will fit within HMMWV space, weight and power constraints, and is expected to cost less than $750K per unit. The overall execution of the Phase I effort, directed at providing a radar with a rapid development, will fall into three main tasks: 1) refining the baseline radar design characteristics; 2) analyzing performance to insure the design meets operational requirements; and 3) determining the anticipated development cost and schedule.

Title:Low-Cost Hit-to-Kill Munitions for Anti-Mortar, Anti-Rocket, Anti-Missile Capability
Abstract:Tanner Research proposes to modify an existing missile or munition, embedding an autonomous hit-to-kill intercept capability, to develop near-term a counter-munition to defeat incoming low-cost ballistic threats like mortar, rocket and missile attacks. The significant technical challenge is to develop both low-cost detect and intercept guidance, and hit-to-kill maneuverability in an autonomous kinetic energy format. Tanner Research, working with Raytheon Missile Systems, will adapt an existing imaging sensor used to detect `coming-at-you' threats, for use as a micro-scale seeker system in a hit-to-kill application. The guidance and control (G&C) commands will be inferred from an existing moving point target detection and sensor-processing (SP) algorithm, and used to implement hit-to-kill maneuverability using existing micro thrusters or gas-actuated canard fins. Enhanced lethality on impact can be gained by using a reactive material airframe. Tanner's objective is to adapt component technologies that will integrate generically with any of several Navy munition platforms, including: ground-launched 2.75-inch rocket as a variant of the air-launched LOGIR; or, the shoulder-launched imaging sensor munition. Both are being developed at China Lake.

Title:Sensor/System to Counter Mortar, Rocket, and Missile Attack
Abstract:The novel feature of the proposed firefinder radar system is an electronically steerable antenna (ERA) that does not require expensive phase shifters. This radar tracker can enhance the search, detect, and track scenario by permitting the search area to be tailored to specific missions, for example, detection and warning of incoming mortar, rocket, or missile rounds; tracking of the round's ballistic trajectory to calculate impact and launch points; support automated precision counter fire; and low probability of intercept operation in areas where it is desirable to deny the enemy knowledge that a radar is in operation. The antenna design can be tailored to transmit one or more narrow-beams, which can be steered to rapidly cover larger sectors, or to avoid illumination of prohibited sectors. The incorporation of an electronically reconfigurable antenna into the radar system enables the following advantages to be realized as compared to radars that use conventional transmit/receive-module apertures: - Dramatic cost reduction - 300 times lower - Weight reduction - 10 to 15 times lower - Digital beam forming for steering, tracking, nulling - Instant creation of individually controlled multiple beams - Extremely flexible reconfigurability of antenna beam patterns - Stealth operation

Title:Low-Loss Miniature Optical Time Delay Modules
Abstract:Leveraging on our industry leading switchable photonic delay commercial product offerings, Agiltron proposes to develop the next-generation 8-bit delay line that meets the challenging requirements of lower insertion loss and higher switching speed. The next-level performance improvement will be achieved by implementing a new precision glass micro-optic fiber assembly technology in combination with the use of thermal-expanded beam fibers that promise a several fold miniaturization of the device. The present invention provides an inexpensive and low loss fiberoptic module for emerging microwave photonic applications. Our approach is state-of-the-art in design and closely coupled with proven fiber optic component manufacturing techniques, holding the promise of realizing practical optical digital delay with performance and cost that have not been previously achieved. Constructed using all solid-state inorganic electro-optic material, the proposed switch overcomes the limitations in speed and long-term reliability associated with other approaches. A low loss and high-speed fiberoptic 8 bit reconfigurable true time delay device with large dynamic range exceeding microseconds will be demonstrated in Phase I.

Title:Optical Time Delay Modules for RF Systems and Telecommunications
Abstract:Eight-bit optical true time delay devices have been demonstrated on a new low loss high index contrast photonics platform. In this proposal the performance (i.e. loss and speed) of high-index monolithically integrated programmable delay circuits will be optimized and systems research will be conducted to select complementary components to realize practical systems. High index glass planar lightwave circuits will lead to integration densities of a 100-fold improvement relative to conventional processes, thus dramatically reducing the size, power consumption and cost of optical true time delay circuits. Reliability is dramatically improved as the devices have monolithically integrated switches and delay lines within a single chip relative to systems based on discrete photonic components. In addition to components research, an output of this program will be a plan to test and demonstrate systems based monolithic true time delay devices.

Title:Highly Scalable Low Loss Fast Tuned True Time Delay Module Based on Dispersion Enhanced Photonic Crystal Fibers
Abstract:To provide DARPA with a high-resolution (>8 bits) optical time delay module exhibiting low optical insertion loss (< 3 dB) and fast reconfiguration time (< 10 micro-seconds), Omega Optics proposes a low-loss, fast-tuned true time delay (TTD) module based on dispersion enhanced photonic crystal fiber (PCF) in conjunction with a fast wavelength tunable laser. Low insertion loss of 3 dB is achieved through the employment of conventional fiber numerical-aperture matched PCF connection, which is to be designed and fabricated in this program. Also, due to the enhanced dispersion (D > -2500 ps/nmkm), time delay from 0s to 10ns can be continuously obtained with less than 80m PCF within a wavelength tuning range of 50nm at 1550nm while maintaining a switching time faster than 10 micro-seconds. Compared with highly dispersive silicon fiber (D ~ -100 ps/nmkm), the total length needed is shortened by 25 times. Consequently, the overall volume and weight is decreased by 25 times. To prove the feasibility of the TTD module, the design and fabrication of highly dispersive PCF and fast tunable laser, and the characterization of the TTD module will be performed to achieve the system goal. Success of these tasks will lay a solid foundation for the phase II and phase III continuation.

Title:Fast Switchable Wavelength Selective Integrated Optical True Time Delay Modules based on Ultralow loss, Athermal and Polarization Independent Waveguide Platform
Abstract:The objective of this proposal is to develop innovative fast switchable (~200ns), wavelength selective, integrated optical true time delay modules based on ultralow loss, athermal and polarization independent waveguide platform with an insertion loss of <3dB for 4 and 8-bit RF system and telecommunication applications. The proposed approach is based on wavelength selective time delay switching via a fast switchable tunable laser with wavelength selective delay lines. Passive wavelength selective time delays are provided by our record breaking ultra-low loss (i.e. <0.045dB/cm over O/C/L bands with a Dn of 1.6%) Teflon-based perfluoropolymer waveguide platform, where array waveguide gratings (AWGs) and delay lines are monolithically integrated. Fast reconfiguration is realized by a digitally switchable (i.e. 8-bit) tunable source based on Sample Grating Distributed Bragg Reflector (SGDBR) laser. In the proposed design, digital control of the TTD module can be processed at the SGDBR lasers with an 8-bit digital operation, while monolithically integrated AWG and delay lines provide all passive TTD signal processes, resulting in more simple system architecture. Furthermore, VLSI fabrication of monolithically integrated AWG and delay lines enable superior control of the resolution of the delay lines (~1micron), thus providing sub-picoseconds time delay control.

Abstract:AMBPTech in collaboration with Dr Wayne Anderson's group at SUNY Buffalo proposes to develop a technology for manufacturing high performance GaN transistors on roll to roll flexible non-conducting foils. This effort will transfer the leading research done at the University of Buffalo in the area of high mobility thin film transistors on thin polyimide foils to AMBP Tech which will leverage propietary processes in thin film deposition and laser annealing to produce high mobility material (~2000cm2/Vs). Phase II will consist of optimizing the deposition and annealing parameters, as well as monolithically fabricating arrays of slot antennas, resistors, capacitors and HEMTs. The latter effort will create an array of MMICs that will prove the concept that a high angular resolution antenna for radar applications can be monolithically fabricated.

Title:Large Area Portable Radar Antenna Arrays
Abstract:In this Phase I SBIR proposal, MicroConnex (MCX) proposes to investigate the fabrication of arrays of high-performance thin film silicon (Si) transistors on flexible polymer films. There is a strong need for high performance semiconductor devices for applications where high frequency operation, light weight, and conforming to a curved surface is required for radar and other applications. Suitable products are not commercially available. MCX proposes to investigate a transfer process for producing high-performance thin film Si devices on flexible polymer substrates. Initially a feasibility study will be conducted in order to assess the practicality of MCX's proposed proprietary process. Some basic proof-of-concept experiments will be conducted. The proprietary process involves depositing elemental Si on a metal substrate at high temperature, and then transferring the fabricated devices to a polymer film. The process is completely scalable and large arrays of devices can be fabricated and transferred simultaneously. In Phase I, MCX will work with the University of Washington to perform device and process modeling. Modeling done at the UW indicates that the transistors may be useful up towards 25 GHz. In Phase II, the device fabrication will be optimized and scaled up for use with large flexible substrates.

Abstract:The objective of the proposed SBIR Program is to establish the feasibility of cost-effectively fabricating a large-area, high-performance, mm-wave radar antenna array on a flexible polymer substrate using roll-to-roll processing. This will be accomplished by further developing and refining innovative laser processing and polymer film processing technologies developed by the MicroContinuum-UCF team, and taking advantage of the unique physical properties of nanoparticle powders. Comprehensive analysis and modeling will be performed to determine the lowest risk ways to apply these technologies. Experiments to develop and demonstrate solution(s) to the most challenging aspect, the low temperature formation of Schottky antenna-structures that provide high mixing efficiency and good mm-wave absorption characteristics, will be carried out and the results reported. The possibility of ultimate low-cost, high-volume manufacturing will be maintained by developing methods that are specifically implementable by continuous roll-to-roll processes.

Abstract:This proposal describes an innovative approach to the objective of developing a large area portable antenna with support electronics including high power, wide bandgap, transistor amplifiers on very large flexible metal substrates. We believe that the refractory nature of wide bandgap semiconductors will also allow operation at very high temperatures if necessary. In addition, the very high breakdown field and saturated drift velocity of the wide bandgap material predict not only Fmax values exceeding 80 GHz but also high (1.0 -2.0 kV) operating voltages. Maximum Available Gains in excess of 18 dB at 10 GHz are predicted, along with Power Added Efficiencies of 45+ % (Class A operation) and 70+ % (Class B operation). Pulse power outputs of the order of 1 MW for a 1 usec pulse are expected.

Title:Embedded control of an Active Structural Integrity Monitoring System using interlaced PZT and Thin-Film Transistors
Abstract:In recent years, Structural Health Monitoring (SHM) is increasingly being evaluated by the industry as a possible method to improve the safety and reliability of structures and thereby reduce their operational cost. However, the scalability and applicability of SHM systems for the monitoring of large structures is still a challenge. Sensors and actuators of a structural health monitoring system can be integrated with a large structure but may be difficult to control using externally located electronics. Acellent Technologies, proposes to develop innovative technologies for embedded control of a network of actuators and sensors using thin-film transistors. The resulting system will have the advantages of (1) versatility and flexibility for application to structures of any geometry and configuration, (2) enhanced resolution for structural integrity monitoring, (3) low-cost and (4) extreme portability. The development will utilize Acellent's current SMART layer technology that uses a network of sensor and actuators embedded on a thin dielectric film to monitor the health of a structure. Phase I will be aimed at development of a concept design using macroelectronics and demonstrating the working of a prototype system.

Title:Large-Asset, Intelligent, Composite-Matrix, Multifunctional Sensor Networks
Abstract:The ability to efficiently utilize the large surface area of entities such as buildings, tanks, and ships as active, intelligent skins will allow these assets to become part of a larger, highly-responsive, complex nervous system in mission critical scenarios. This will enable information that would otherwise not be available for real-time monitoring and response. Large-area assets would also allow efficient harvesting of lost energy and a feedback to the original system, leading to significant energy and cost savings. One of the key limitations to this advance has been the lack of large-area manufacturing and integration capability that would best utilize the enormous potential of such systems. In this proposal, we will develop a large-area, intelligent, composite-matrix sensor network using a combination of reinforced woven fabric, and microelectronic processing technologies. In the Phase I program, we will develop a design of the composite-matrix sensor structure and validate the process and equipment to enable scaling to large areas. In the follow on Phase II program, we will demonstrate a large-area sensor network in collaboration with an end-user, and demonstrate a functional product. We will commercialize the final product and offer it to the military and commercial markets in Phase III.

Title:Printed Electronics Processing for Structural Integrity (PEPSI)
Abstract:NextGen Aeronautics, Inc., teamed with Penn State and Virginia Tech, proposes to apply cutting edge research in flexible organic electronic devices and circuits toward the development of a unique printing technology for structural integrity monitoring sensors. Innovative concepts that NextGen can bring to bear on this challenge include existing flexible sensor technologies and associated flexible circuits, conductive polymer printable interconnects, and nanotechnology-based printing. The objective is a low-cost structural health monitoring system that may be applied to a diverse array of military and commercial business sectors. The primary advantages offered by the proposed system versus state-of-the-art alternatives are: low cost; light weight; continuous operation, on-demand assessment; and the ability to evaluate the state of an entire large structure. Additionally, the proposed system will be equally applicable to metallic, composite, plastic, ceramic, adhesive, sealant and coating materials. Objectives of the Phase I effort will be to design a printable sensor with associated signal processing electronics and demonstrate printed sensor fabrication as a cost-effective alternative to existing methods. In so doing, the NextGen/Penn State/Virginia Tech team will raise the Technology Readiness Level (TRL) of this approach from 1 to 3.
