Title:Design for Six Sigma Through Statistical Simulation Methods
Abstract:The United States Navy has identified the need to develop innovative technologies that reduce the costs of manufacturing weapon systems and components. This requires a commitment to using statistics and design of experiments (DoE) methodologies to fully understand and characterize manufacturing processes. The vast amount of data required for full process characterization combined with complex statistical analysis often makes this practice prohibitive for most computer-aided systems. This proposal by AET, Inc., directly addresses dual use methods for achieving advanced industrial practices such as six sigma manufacturing in both the military and the private sector. A practical six sigma design system can be achieved by integrating existing tools and techniques in a unique way that achieves the goals of both the Navy and AET, Inc. The environment to perform this integration is named STADIUM. The use of STADIUM and its design of experiments statistical analysis capability will allow extraction of six sigma design and process parameters to be used in the performance simulation and evaluation.

Title:Large Area Thin Film Corrosion Resistance via CCVD
Abstract:Corrosion damage to aluminum structural components is very costly to both the government and commercial industry; viable treatments and/or protective procedures are required to limit it. Paint and related conventional coatings are commonly used to combat corrosion, although such coatings often may degrade quickly requiring frequent reapplication or touch-up; this is expensive and labor-intensive, especially in the field. Higher performance conversion coatings are prepared with processes which use hexavalent chromium, now considered to be a major health and environmental hazard. Thus, there is a compelling need for alternative, environmentally benign, low-cost coating technologies to protect aluminum components and structures subjected to corrosive environments. In addition, reduced weight is desired. MicroCoating Technologies, Inc. proposes to develop its safe, clean, economical Combustion Chemical Vapor Deposition (CCVD) process to fabricate high-quality, dense, pinhole-free, metal-oxide thin films as replacements for the chromate conversion coatings. The patented CCVD method is an open atmosphere deposition system capable of true heterogenous vapor deposition of dense, high quality films but at a fraction of the cost of the traditional vacuum processes, Chemical Vapor Deposition and Physical Vapor Deposition (PVD). Since CCVD processing is not confined to a reaction chamber or furnace, coating of large objects such as aircraft structural components is viable. We have already completed experimental work on low temperature deposition of CCVD coatings on aluminum and copper substrates. Our trial coatings display excellent performance as corrosion-barriers under wet conditions in tests performed by both Battelle (1300+ hours of saltwater spray) and an industrial partner (30 day SWAAT). We will detail these preliminary results further in the proposal. In Phase I, we will build on this initial success and work with our industrial collaborators to develop CCVD metal-oxide coatings with negligible weight for protection of aluminum structural components in both military and commercial applications. Phase I success will lead to a Phase II program to scale and automate the CCVD process for high rate, low cost production. This SBIR research will be planned, developed and commercialized through Phase III in collaboration with our industrial partners.

Title:Technology for Affordability
Abstract:The towed array capabilities of the US Navy combine high reliability, high channel count, long aperture and low self noise to provide an underwater acoustic superiority not matched by any other Navy. This superiority has also brought with it unwanted high production costs for these arrays. The next generation of Naval towed arrays with increasingly larger aperture may be out of the reach of a cost conscience Navy. The innovative technology described in this proposal will dramatically reduce the costs of providing this underwater acoustic superiority by automating the construction of towed arrays. It will provide a continuous array design ideally suited for optical hydrophones and telemetry. It will dramatically reduce the number of modules used to form an array and eliminate the fiber and strength member splices required at these terminations. The technology uses machine wrapped open cell foam, machine wrapped optical fibers which carry the telemetrized hydrophone signals, machine installed internal strength members, and a continuously extruded outer hose wall. This automated construction maintains high array reliability in a low flow noise hydroacoustic design while dramatically reducing the fabrication costs.

Title:Manufacturing Technology for Affordable Composite Structures
Abstract:Ebert Composites Corporation (Ebert) proposes to develop an advanced combined pultrusion and machining concept capable of producing affordable precision machined pultruded components for use in large composite structures. Previous research efforts have shown the merits of composite truss structures using a novel interlocking system developed by Ebert. The system allows assembly of structures without adhesives, bolts, or joint reinforcing material. Large, very high strength, easy to assemble structures are possible using relatively low cost materials. However, extensive precision machining of the base pultruded material is required to produce individual components of a structure. Previous research has also shown that this will require multiple machining steps separate from the pultrusion process to produce the strongest possible joint. These machining steps are time consuming, which restricts the ability to produce low cost components. During Phase I, Ebert proposes to design a pultrusion process that seamlessly integrates high speed precision machining. General machining concepts will be developed and tested using in-house equipment with a goal of demonstrating the capability of synchronized machining of pultruded components. The option period would develop a test truss structure and a pultrusion/machining specification as a lead-in to Phase II development.

Title:TERFENOL-D Lamination Process Cost Reduction
Abstract:All high performance TERFENOL-D sonar devices require the drivers to be laminated for eddy current control. The process of laminating TERFENOL-D to present interlamina resistivity requirements results in low yields due to considerable material loss and is, therefore, a wasteful process. The objective of this program is to define and experimentally verify accurate interlamina resistivity levels for high performance TERFENOL-D drivers which also ensure acceptable power losses. Phase I will conclusively prove analytical theory which predicts relative independence of driver performance upon lamina conductivity. Proving that existing requirements can be safely relaxed, will have an immediate effect on TERFENOL-D high performance sonar driver yields resulting in almost 50% cost reduction.

Title:LASER Induced Thermal Strain Forming for Repair, Production, Rapid Design & Prototyping (LITS-FORM)
Abstract:The purpose of this Phase I proposal is to verify the feasibility fro use of a robotic laser fabrication and repair system and to show how this innovative technology application will reduce costs of Warfighter systems and components, and improve performance and reliability. This system will provide impact in the shipyard, on the factory floor, in the aircraft repair depot and onboard ship. The number of potential military applications for this technology is very large, and provides the potential for significant savings of resources and time in production of military hardware, fabrication of defense relate components, and erpair and maintenance of esisting systems. Based on the integration of existing techologies into an innovative new computer-based process modeling and planning environment, this development will provide a demonstration of the apllications in Phase I. It can be applie dto large-scale or few-of-a-kind manufacturing, or fast production of long procurement lead-time parts, for the rapid prototyping of components that have real evaluatable and testable form & fit capability, and for repair and maintenance thru reforming of damagd & distorted parts. The system that will be developed is generally based on COTS hardware; and both the hardware and software is reconfigurable; The operator environments are intuitive, interactive and graphical. It will use a relatively low-cost PC computer-based 3D-CAD technology from Intergraph Corporation that is fully compatible with the Integrated Ship Design System currently under development for the Navy by Intergraph.

Title:Induction Carburizing--A Novel Cost Effective, Environmentally Safe, Affordable Technology
Abstract:Carburizing of steels to improve wear resistance is an old but widely used process. Current furnace technologies are expensive because their extensive requirements for time, space, labor, materials, energy and maintenance, and are harmful to the enviroment due to active atmosphere and heat losses. Separate equipment is needed to establish desired properties in the part case and core. The proposed New Induction Technology (patent pending) will dramatically increase customer affordability by reducing the costs of manufacturing and repair of many important parts of aircraft, rotorcraft, ships, submarines, weapon systems, and correspondingly their life-cycle costs. Induction Carburizing can rapidly produce both local and overall protective surface layers not only on steels but on Ti base alloys. There are no restrictions as to part shape or dimensions. The carbon content, depth of penetration, microstructure, and properties can be obtained in seconds or minutes and adjusted as required for reliability and longevity increasing. Unlike current technologies the core temperature and properties remain unchanged, required subsequent cooling, quenching, and reheat treatment can be done simultaneously in the same installation. Sanova-Polytech, Inc. has outlined a comprehensive Phase I Program to show the feasibility of Induction Carburizing and to perform a preliminary cost analysis for transition of this New Technology to commercial usage.

Title:Management Tool for the Battlespace Environment:
Abstract:An HLA tool, i.e., a battlemaster, is needed to enable a user to easily configure, control, and monitor a large-scale distributed exercise,. MK Technologies has substantial expertise in HLA, is the leading supplier of HLA tools, and is a developer of networked games containing battlemaster components. Therefore, MK is the ideal candidate to develop the battlemaster required by the M&S community. MK Technologies will develop an HLA Battlemaster that supports configuration, control, and monitoring of both federations and individual federates. The Battlemaster will provide access to the required standard set of RTI's services, the Management Object Model, and the federation's FOM. In addition, the Battlemaster will provide a specialized set of services through its Battlemaster Application Programmer Interface (BAPI), which supports federate-specific plug-ins. MK's Battlemaster will be based on MK's commercial HLA Plan-View-Display, lowering time requirements, cost, and risk, while providing additional capabilities that are not ordinarily found in a battlemaster. At the beginning of Phase I, MK will interview operational users to determine the functional requirements of the HLA Battlemaster. These requirements will guide development of an object-orientated design specification. With the newly created design and MK's existing commercial PVD, MK will create an initial Battlemaster prototype. To complete the spiral development cycle, MK proposes a Phase I option to develop a test federation. We will iterate upon four components (requirements, design, prototype, and test federation) during Phase II to create a powerful, robust, flexible HLA Battlemaster. MK can achieve all this in Phase I by leveraging existing tools and technology, and by applying its experience in both HLA and design and development of battlemasters for networked games.

Title:VISGEEN: Virtual Interactive Scenario Generation and Execution Environment
Abstract:The Modeling and Simulation (M&S) community is faced with increasing requirements to promote interoperability and reusability. To address this issue, DoD has defined the High-Level Architecture (HLA) as the standard to which models and simulations must conform. The HLA provides the infrastructure that allows conforming models and simulations to interact. However, neither the HLA or current simulation environments provide the high level coordination capability needed for the activities involved in creating and managing complex, synthetic, battlespace environments. In this SBIR, Modus Operandi (formerly Software Productivity Solutions) proposes to leverage our experience in distributed simulation and complex engineering environments to develop a Virtual Interactive Scenario Generation and Execution Environment (VISGEEN). VISGEEN supports the full simulation life-cycle of the synthetic battlespace environment, from scenario construction using integrated models and simulations, to run-time initialization, monitoring, control, and visualization of the participating simulations. In Phase I, Modus Operandi will integrate VISGEEN with existing M&S assets and use them to create a scenario for execution. VISGEEN will then initialize, manage, and visualize the scenario executing within the context of the HLA. This prototype will provide a solid foundation for Phase II full-scale VISGEEN implementation.

Title:Advanced Solid State High Repetition Rate Modulator
Abstract:This effort will leverage DTI's existing PowerMod` Solid State Switching technology to develop a 20 kV, 100-400 kHz pulse modulator for advanced W-band pulse Doppler radar applications. Key features of this effort will be the extension of solid state switching techniques to 100-400 kHz at high support enhanced effective surface-based radar detection and tracking of low RCS / low altitude targets such as cruise missiles, which currently pose a significant threat to naval assets. Additionally, this effort will demonstrate voltage regulation better than 1 part in 10,000 in a pulsed power environment. This level of voltage regulation is critical to the performance of high power RF tubes, such as klystrons and TWTs, in applications where phase stability is a key performance parameter.

Title:A HIGH-REPETITION RATE PULSE MODULATOR FOR HIGH-POWER
Abstract:The proposed program will concentrate on the design of pulse-amplitude modulators using innovative architectures to overcome the limitations of conventional designs in driving predominantly capacitive loads, such as the modulating anodes of high-power microwave vacuum tubes. The design will necessarily be capable of operation at high pulse voltage levels and at high pulse repetition rates. Typical of such an architecture is the "quasi-resonant" arrangement described in 11.1.8 of "High-Power Microwave-Tube Transmitters" (Reference 1 of N98-003), wherein the capacitance associated with the modulating anode is charged and discharged through a resonating inductor, or inductors, in a sinusoidal fashion, transferring stored energy rather than dissipating it. There are numerous variants of this concept which must be investigated in order to determine an optimum design depending on the type of electronic switches and how they are used. The program will include the evaluation of the various available electronic switches, including Field-Effect Transistors (FETs), Insulated-Gate Bipolar Transistors (IGBTs), Silicon-Controlled Rectifiers (SCRs), conventional triode and tetrode vacuum tubes, and the "Crossatron" gas-filled switch. This evaluation will concentrate on selecting the best electronic switch for this application. The effort will also include breadboarding of appropriately scaled portions of complete switches.

Title:Long Life Thermal Battery for Sonobuoy
Abstract:The prospects of significantly enhancing antisubmarine warfare (ASW) sonobuoys require exponential improvements in thermal battery capability. The fused-salt primary battery LiSi/CoS2 has shown tremendous progress in meeting the advanced requirements. Adaptation of recent advances in high-rate rechargeable thermal batteries provides a cost-effective approach for fully meeting size 'A' sonobuoy performance objectives. Specifically, an innovative super insulated container (vacuum/multifoil, which is 10-100 times as effective as Microtherm) promises to extend operating times beyond 4 hours to 12 hours. Reduced thickness of insulation would allow increased battery stack diameter and capacity (by 25%) to exceed 200 ping-seconds or power at greater than 13 kW. Rechargeable thermal battery peripheral seals, thinner (by 50%) fiber-separator; FeS2-CuFeS2 cathodes with 25% higher capacity density and lower-melting electrolyte are options for further increasing 'A' size sonobuoy battery performance and life. Battery life and performance could be doubled concurrently. Phase II would demonstrate the improved sonobuoy battery and aid in commercialization of the rechargeable thermal battery. A "dual-use" objective enables cost-effective deployment of the long life thermal battery for the 'A' size sonobuoy.

Title:Flexible Shear Stress Smart Skin for Submarine Applications
Abstract:Physical Optics Corporation's (POC) objective is to develop a flexible MEMS-based shear stress sensor for Navy radio-controlled submarine model experiments. An array of transducers can enhance the flow characteristics of model hulls and control surfaces. POC proposes development of a novel waterproof shear stress transducer that can detect the direction and magnitude of shear stress under a water pressure environment with high spatial and temporal resolution. The device can assist with evaluating the hydrodynamic merit of new submarine designs. A robust stress transducer uses a floating element, coupled with fiber Bragg gratings (FBGs), which is deflected when exposed to fluid flow. A transducer uses Bragg gratings etched onto a symmetrical pair of fibers. A pair of FBGs balances deflection of the floating element, thereby reducing noise caused by the temperature/pressure effect. Gaps within the exposure surface of the floating element are covered by a silicon rubber thin film to resist water contamination. In Phase I, proof-of-concept will be demonstrated for waterproofing techniques on a MEMS-based transducer. A smart sensor network will be deisnged to address a large number of proposed devices to build a solid foundation for Phase II.

Title:Global Shear-Stress Distribution Using Water-Proofed Hot-Film Constant Voltage Anemometer (CVA)
Abstract:Boundary-layer flow characteristics, such as the location of the laminar-to-turbulent transition, flow separation and flow reversal regions, as well as surface shear-stress distribution on marine vehicle models, will be measured using micro-thin, multi-element hot-film sensor arrays coated with electically non-conducting, water-proof polymer material. Tao Systems' Constant Voltage Anemometer (CVA) instrumentation system will be adapted for under-water applications to obtain high sensitivity and high dynamic response at low sensor currents. The low power dissipation in hot-films operated with CVA will significantly reduce or eliminate bubble formation, as well as corrosion causing electrolysis associated with conventional techniques. The high signal-to-noise ratio of CVA, coupled with large bandwidth, even at low sensor currents will eliminate most of the problems encountered by conventional anemometers in under-water applications. Furthermore, since the power dissipated by hot-film sensors in the CVA-mode of operation is linearly proportional to the voltage output (and not to the square of the measured output voltage, as in constant temperature anemometer), an order of magnitude reduction in measurement error will result with the proposed innovation. The feasibility of the proposed approach will be demonstrated during Phase I by conducting tests on an instrumented model in a water tunnel.

Title:Waterproof MEMS-Based Conformal Shear Stress Sensors
Abstract:There exists a large need in the fluid mechanics community for waterproof micro shear stress sensors. The United Micromachines MEMS hot-film shear-stress sensor with underlying vacuum cavity is the only proven laboratory prototype micro shear stress sensor. In addtion, these sensors can be fabricated on a flexible substrate that can conform to curved test surfaces. With additional effort, the sensor technology can be advanced to the point where the sensor will be a commercially viable product. One of these efforts must be directed in the direction of waterproofing, which will allow the sensors to be used both underwater and in wet (ie raining or very humid) conditions. Initially, United Micromachines will concentrate on developing and testing waterproof coatings for use on the already developed sensor. The testing will concentrate on the waterproofness and pressure effect on sensor performance. In Phase II, United Micromachines will develop the packaging and electronics integration schemes necessary for acceptance by the fluid mechanics community.

Title:Polymeric Hose Health Inspection Using Microwave NDE Techniques
Abstract:Hoses are critical to the operation of hydraulic, power train, and auxiliary machinery aboard ship and in industrial applications. This project will develop a hose inspection tool to economically and practically assess hose health in place. Reliable inspection of hoses reduces maintenance costs while decreasing the rate of hose failures and related accidents. Microwave methods for hose nondestructive evaluation (NDE) can identify critical hose defects at low cost with minimal operator training. Microwave hose NDE can be done using portable handheld devices roughly the size and weight of a flashlight. Microwave inspection is based on the change in dielectric properties associated with hose defects like delamination, disbonding, and wall thinning. These changes are detected by sensing reflected microwave energy, and complex signal processing routines are not required to observe them with high reliability. Microwave NDE is done in real time - results are immediate and can be as simple as the blink of an indicator light - so position recording or complex scanning equipment is not necessary. Development of microwave NDE for hose inspection will result in a battery powered NDE tool - more like a battery operated drill than a computer driven system - and as such has a very high potential for commercial success in both Navy and industrial applications. TRI/Austin has committed to funding - at no cost to the project - a business study by an MBA candidate team to map the path for moving microwave hose NDE to the commercial market after development.

Title:A Temporally Resolved Thermal Imager
Abstract:There is a need for a robust, non-invasive system for the measurement and recording of single-event (non-repetitive) time-dependent high temperatures. Measurement periods for these applications can range from microseconds to several hundred milliseconds. Individual measurements must be made on the order of every microsecond or more frequent. A2Z Technologies Corporation proposes to design and develop instrumentation which is broadly applicable to high-speed temperature measurement applications for Government (i.e., DOD, NASA, DOE) and industrial applications (Engine manufactures, manufactures of explosives, etc.). Specific capabilities for the proposed thermal imager are 1) non-intrusive, high temperature measurements, 2) multiple point (256 x 256) simultaneous measurements, 3) time-resolved measurements with controllable sampling intervals (1 ms - 50 ms), and 4) operate in harsh physical and EMI environments. During the proposed 6 month effort, A2Z Technologies Corporation will perform initial measurements at Naval test facilities, test the interference environment produced by the pulsed x-ray sources, design the prototype instrument, and develop, test, and demonstrate a Phase I breadboard system. All Phase I activities are for the purpose of proving the system feasibility. In addition, a Phase I option is proposed that includes 1) additional system testing and 2) prototype system design.

It will also utilize an internal video camera to allow video recording of the field-of-view during the test events with a standard video cassette recorder. Two built-in temperature sources will allow verification of system calibration, obtained in the laboratory using objects of known temperature. The design will incorporate features of an existing ARA pyrometer which has been demonstrated to record temperatures in reactive material tests with little electrical interference from flash radiography.

Title:Inlet for Turbofan Powered High Performance Tactical Missiles
Abstract:The duPont Aerospace Company, Inc. proposes to design an innovative inlet suitable for a hypersonic cruise missile. The innovative features consist of an inlet cowl which rotates outward from the retracted position to accommodate the airflow requirements of the engine, a coordinated variation in throat area and possible elimination of boundary layer bleed. The retracted position allows the engine to be closed off for hypersonic glide operation, and the various extended positions match the engine airflow requirements over the Mach number range from zero to six. The coordinated throat area variation matches the contraction necessary to reduce the inlet Mach number to a low value prior to the final normal shock. Boundary layer bleed requirements may be eliminated providing a more efficient overall solution if the resulting distortion is acceptable for the turbine engine. The Phase I work consists of CAD design and associated aerodynamic analysis using duPont proprietary methods which have been thoroughly proven in the NASP program. The final result is expected to be an optimized inlet that meets all system requirements.

Title:Lightweight, Cost Effective and Durable Metal Matrix Composite Track Components
Abstract:Air transportability, buoyancy and acoustic signature of future USMC/Navy 16 and 30 ton class tracked vehicles such as the Advanced Amphibious Assault Vehicle (AAAV) will be greatly enhanced if lightweight track shoes are developed to replace the existing forged, surface hardened steel components. Foster-Miller proposes to develop a tailored metal matrix composite (MMC) track shoe/pin component that will match the wear and strength performance of the current steel shoe at less than half its weight. Further, our MMC fabrication method (pressure casting) uses low cost nonstructural tooling, achieves net shape parts and is scaleable, which will produce high performance and cost-effective components. The Foster-Miller team will include a major foundary who is responsible for the design of track components for the AAAV, and a targeted component producer (beyond Phase II). In Phase I, Foster-Miller will produce MMC specimens for mechanical and tribological testing, and a scaled "show and tell" demonstration article to prove the shape capability. In Phase II, Foster-Miller will optimize materials and processes involved, prove repeatability and consistency in track component performance, and demonstrate cost, weight and performance benefits over the baseline component(s).

Title:Phase Controlled PM Generator for the AAAV
Abstract:The Marine Corps next generation amphibious assault vehicle requires improved power generation capabilities due to increased power demand. Versatility (e.g., capability to drive two generators in parallel), high efficiency, and temperature independent voltage regulation are the goals of this development. Unique Mobility, Incorporated is ideally positioned to achieve these goals due to 15 years experience in applying small, lightweight, and efficient brushless permanent magnet (PM) motors and generators within vehicle applications. Unique is currently involved in many hybrid electric vehicle motors and generator programs, collaborating with Orbital Engine Corporation, Northrop Grumman, Houston Metro Transit Authority, US Department of Transportation, Deere & Company, and DARPA, as well as others. Within generator applications specifically, Uniques method of delivering constant voltage over a wide range of generator speeds and temperatures results in a minimum power electronics and delivers high efficiencies, usually exceeding 90% across a wide band. This experience is vital to improving the AAAV power generation system, where the Phase I goal will be to design an optimized generator with associated electronics. System efficiency in excess of 85% across the operating region is anticipated. A set of conceptual drawings along with prototype and production cost estimates will be included in the Phase I report.

Title:Multiple Beam Antennas with Semi-Constrained Beamformers
Abstract:A mobile satellite communications link operating from vehicles on-the-move would provide significant benefits to the Marine Corps in the battlefield environment. The antenna should be capable of simultaneous and rapid tracking of two satellites while the vehicle is in motion over rough terrain, as well as providing ultra-wide bandwidth (C-band through Ku-band), medium to high gain, low profile, rugged, minimal size and mountable on military vehicles. Affordability is also a significant issue. This Phase I effort will focus on multiple beam antennas with semi-constrained beamformers because, with their inherently wide bandwidth, multiple beam capability, and relatively low cost, they offer the most realistic and affordable approach to meeting the above requirements using current state-of-the-art technology. The feasibility of several innovative beamformer and aperture approaches will be investigated and compared with existing designs. Results of a preliminary evaluation using a computer model programmed for this proposal are included in the proposal. The ultra-wide bandwidth requirement poses design challenges due to mutual coupling between elements and intermodulation. The Principal Investigator has wide experience in array design and holds two patents for wideband phased array elements.

Title:It's the Drop
Abstract:How do you hit a two-meter square target 500 meters away with a subsonic, unguided SMAW-D missile? At 100 meters, drop is about as important as other factors. At 500 meters, other factors have increased linearly but drop has grown by a factor of 30 and is the dominant factor. Even a 9mm revolver can hit the above target if you get the drop right. To compensate for drop, you need to know range AND velocity. R can come from either a spotting rifle or a laser rangefinder. A commercial, off the shelf laser rangefinder available for less than $200 may do a better job than a spotting rifle. While usable as-is, we explore integrating this rangefinder into the SMAW-D launch system. Launch velocity of the missile drops sharply with temperature and this problem must be addressed. If the velocity of a cold missile not only drops but is inconsistent, then the only answer is a guidance system. We explore a simple, no computer guidance system to compensate for gravity. While this system can easily be enhanced, it solves the immediate problem defined above.

Title:High Accuracy GPfog Azimuth and Attitude Sensor
Abstract:KVH Industries proposes to deliver a high precision GPfog azimuth and attitude sensing system based on fusing three low cost sensor technologies: ultra short baseline carrier phase measurement GPS utilizing low cost GPS chip technology; uniquely affordable three-axis KVH E-Core Fiber Optic Gyros (FOGs); and a micro-machined commercially available accelerometer sensor package. The fiber optic rate sensors will be fused with GPS azimuth/attitude measurements and accelerometer inputs to increase system bandwidth and robustness and to provide immunity to short term GPS outages. During platform motion, the proposed system will use the change in position inputs from multiple low cost GPS chips to calculate a backup azimuth input to the carrier phase measurement, including stored heading backup during vehicle stops. The proposed three axis attitude and azimuth system will deliver better than 0.4 RMS degree accuracy at a per-unit parts and labor cost below $2,000 (sell cost under $7,000) in small quantities. KVH's proven experience in GPS product fusion (KVH GPS/Compass TACNAV and GPS/FOG Continuous Positioning System), combined with our low cost, robust, low drift FOG technology, make KVH uniquely qualified to solve the solicited non-magnetic high accuracy azimuth requirement.

Title:Advanced Sigint System
Abstract:A notional concept for an Advanced Sigint System is proposed. Features of the concept include use of COTS hardware for most componentry, and use of highly innovative Sonetech algorithms for ESM/ECM resource management, signal classification, Direction Finding, and jammer/ECM control. A novel technique for emitter location in the "urban canyon" environment is proposed in the basic effort; its counterpart in active jamming would allow selective jamming of the emitter while minimizing"electronic fratricide". Study of the active counterpart is proposed as a study option (p.12, para(3)). An overall design implementation will be selected which will maximize flexibility, modularity, and cost-effectiveness of the baseline systems, with growth potential to allow the optional capability to be added later.

Title:Modular Remote Electronic Attack System
Abstract:The Radio Reconnaissance Team of the Marine Air-Ground Task Force must retain the cutting edge in the tools of their trade amidst rapidly changing technology. This assimilation of technology will enable him to conduct electronic attack with precision and effectiveness. The Radio Reconnaissance Team member must have equipment that is versatile, easy to configure, easy to carry, easy to operate, reliable, simple to maintain and support, durable, and functional under the most severe conditions. A self-contained, modular EA system will be most effective in supporting the intelligence gathering mission as it will interface with the Marine Corps Reconnaissance Equipment Program SIGINT Suite-1 (RREP-SS-1). The proposed module will include on-board power, remotely tunable transmitters, and remotely controlled power output. This proposal outlines a four-task approach toward rapid commercialization. The first three tasks will form the basis for the first 180 days of this research effort while the fourth task may be included in a three-month option to the contract. The tasks are: 1) Perform a survey of commercial components, requirements, and operators. 2) Perform exploration / experimentation on the implementation of microprocessor controlled solid state circuitry. 3) Perform a complete design analysis of needed hardware. 4) Conduct a proof-of-concept demonstration. The demonstration will provide a basis on which to determine the technical merit of this approach.

Title:A Stand Alone Environmental Corrosivity Measurement System
Abstract:Corrosion problems experienced by military equipment are severe and expensive; estimates for the Navy alone are more than $1 billion annually. To reduce these costs it is imperative that equipment be monitored for exposure to corrosive environments. Quantitative monitoring programs will help to better understand how to best mitigate the effects of these environments. The opportunity presented here is the development of an integrated environmental monitoring system so that data which characterizes the corrosivity of the environment can be gathered. The instrument will incorporate an innovative integrated sensor suite capable of monitoring temperature, humidity, rainfall conductivity, and corrosivity (e.g. galvanic activity) data over a wide-range of operating conditions. The data acquisition system will be based on a small but sophisticated Micro- Computer Unit which will gather data over long periods of time. Use of this advanced technology will result in a small, lightweight system which can be used in shipboard, airborne, and ground station applications. The primary focus in Phase I is to prove the feasibility by 1) integrating sensors which can accurately and reliably measure these parameters into a stand-alone package using thin-film deposition techniques and 2) demonstrating a prototypical signal conditioning and data acquisition system with remote data retrieval capabilities.

Title:Intelligent Coatings for Corrosion Detection Using Fluorescence Lifetime Imaging
Abstract:Systems & Processes Engineering Corporation (SPEC) and Dr. Richard E. Johnson of LeTourneau University proposes to develop a method to encapsulate and embed corrosion sensitive dye molecules into a intelligent aircraft primer coating. We intend to detect the fluorescence changes of dye molecules interaction with corrosion by-products by using frequency domain fluorescence lifetime imaging (FLIM) technology. The system is based upon the determination of the fluorescence lifetime contrast images of the intelligent corrosion by measuring the amplitude and phase shift of the fluorescence emission relative to an amplitude modulated excitation light source, thus avoiding many of the technical difficulties associated with an intensity measurement system. We intend to also investigate and develop an encapsulation method for these dye molecules based upon previous SPEC work in silica-gel technology. SPEC and Dr. Johnson has extensive experience implementing fluorescence lifetime measurement systems and in the development of intelligent coatings. SPEC has manufactured, demonstrated, and delivered a number of corrosion detection and monitoring systems to NASA Langley, US Army Missile Command, and the Naval Air Warfare Center, Aircraft Division at Patuxent River.

Title:Improved Leak Location System for Aircraft Internal/Integral Fuel Tanks/Cells
Abstract:Program objective is to develop a television system for identifying fuel tank leaks. This leak detection method uses a near infrared camera with illuminator to observe gas flow through any small breaches in the fuel tank wall. System performance is based on the physical principle that reflected scene irradiance is reduced in any area where an illuminator's spectral bandpass traverses a flowing gas with the corresponding absorptive bandpass. In subsequent discussion this leak identification system will be referred to as the Eclipse Detection System (EDS). Proof of concept will be accomplished by designing and testing a prototype EDS that detects the flow of selected unheated or cooled gas through fuel tank leaks. These prototype tests will show EDS's to be: (1) comparable in size and ease of operation to a conventional camcorder, (2) less expensive than proposed or currently available methods, (3) more user friendly, and (4) will provide improved imagery with leak areas shown as black spots and/or plumes on a TV monitor. Conversely, leak detection systems that rely on heated air or gas emissions require a more costly and complex setup to image and control the heated trace gases. Heated trace gases may be corrosive to some fuel tank surfaces.

Title:Cycloidal Propulsion for UAV VTOL Applications
Abstract:The proposed effort will result in the development and wind tunnel validation of a universal pitch cycloidal propeller system which can provide efficient vertical takeoff or landing (VTOL) UAV propulsion. This form of propulsion is currently in use in marine applications, and has been studied by major aircraft manufacturers and the military. Study and wind tunnel test results support the concept; however, until the advent of the micro-computer and associated motion control technologies, efficient cycloidal propellers were only feasible for relatively narrow speed ranges. This effort will capitalize on computer control to provide a universal pitch cycloidal propeller that will allow efficient flight across a wide range of flight speeds and conditions. Cycloidal propulsion provides a unique 360-degree directional flight capability through use of a low-velocity, high-volume flow technique of exceptional efficiency. The cycloidal propeller, which provides both thrust and lift, can make near instantaneous change in thrust direction without re-orientation of the propellers plane of rotation. Major advantages of this system include efficient hovering flight, low-noise signature, near-instantaneous change in thrust direction, wide speed range, safety, and packaging. BOSCH Aerospace, Inc., has teamed with the Raspet Flight Research Center of Mississippi State University to conduct Phase 1. The research will encompass systems engineering, mechanical design, computer modeling, control algorithm development, fabrication, and wind tunnel tests. A fully functional propeller and control system will be completed and tested during Phase 1. Documentation from this effort will include study, design, and tests results.

Advanced Rotorcraft Technology, Inc. (ART) has developed FLIGHTLAB, a prototyping tool for flight dynamics modeling. ART is currently completing a Phase 11 SBIR that has focused on adding extensive flight test support capability to FLIGHTLAB, including the modeling of standard Navy flight test scenarios, the reduction of the resulting data into standardized plot formats and the addition of an integral data base management system to catalog simulation configuration with the corresponding test results, Stottler Henke Associates, Inc. (SHAI) is currently completing a Phase 11 SBIR involving the development of an automated flight test planning program that uses intelligent systems technology to extract baseline information from a library of flight test plans and then guides the user systematically through the test plan development, making extensive use of existing information to facilitate and standardize the process. This proposal addresses the enhancement and integration of FLIGHTLAB's virtual prototyping and virtual test and evaluation capabilities and SHAI's Automated Flight Test Engineering System to produce the Rotorcraft Intelligent Test and Evaluation (RITE) system. The development of an intelligent software system that facilitates the efficient modification of both flight control and simulation software to achieve desired objectives and supports configuration management of the software throughout the test and evaluation process will have a major impact on the rotorcraft test and evaluation community.

Title:Bonding of SiC CMCs to Superalloy Components
Abstract:Many within the Navy and industry believe CMC technologies are at a stage of development ready for insertion into turbine powerplants. As a designer and fabricator of CMC components, Refractory Composites, Inc. (RCI) agrees that SiC CMC materials and fabrication technologies are of the maturity level for use as high temperature components in turbine engines. In order to truly capitalize on the benefits of CMC components, they must be successfully bonded to state of the art superalloys. In this proposed SBIR program, RCI will develop and demonstrate fusion joining techniques for CMCs to superalloys for operation at temperatures above 700oC and capable of withstanding the harsh corrosive environments encountered in Navy turbine engine applications. In addition we will develop stress analysis tools capable of use in designing joined components. RCI has already developed methods of bonding CMC components to metal components for other applications.

Title:Thermoset Resin Development for In Situ Fiber Placement
Abstract:Fiber placement is a technique developed for fabrication of thermoplastic matrix composite structures, but it has been applied to layup of complex thermoset composite structures which are difficult to produce using other methods. It has been used successfully to produce several such structures, eliminating or minimizing problems such as fiber waviness (or marcelling), fiber shifting, resin migration, disbonds and voids. Currently, however, successful use of this technique for thick parts depends upon repeated debulking during fiber placement, and a lengthy autoclave cure cycle is required after fiber placement is completed. Foster-Miller proposes to modify commercial thermoplastic toughened prepreg tape to eliminate these debulking and autoclave cure requirements. A combination of staging, preconsolidation and creation of a highly reactive surface will be employed to produce a prepreg tape capable of full in-situ cure during fiber placement. Foster-Miller has formed a team with aircraft primes Bell Helicopter and Lockheed Martin to realize development of this low cost fabrication process. The Phase I program will culminate in the use of this modified prepreg for in-situ cure during fiber placement of a representative composite subcomponent during the optional task.

Title:Biofidelic Lumbar Spine for Human Response to Aircraft Ejection and Helicopter Crash
Abstract:Spinal injury (vertebra fracture) during aircraft ejection or vertical helicopter crash is a serious problem due to the human body's inability to tolerate excessive +Gz acceleration. Although anthropomorphic test devices (ATD) or manikins have been used to assess, develop and standardize ejection seat and crash safety, they do not represent the spinal response under high acceleration loading. Flex Technology has designed and developed an innovative flexible structure which has the potential to mimic the properties of the human spine for incorporation within an ATD. It is proposed to review the current staus and properties of ATD spinal units as well as human vertebal specimens, research and document the spine's response to high impact loading, to design and develop using dynamic computer modelling an innovative flexible structure that has the stiffness properties comparable to experimentally determined vertebral stiffness, and to construct prototype units for mechanical testing and response verification. The key elements of the proposed unit is its simplistic, continuous, one piece design, and ability to customize the mechanical properties. The unit will be computer designed based on experimentally determined vertebral properties. Phase II developments will include a multi-degree of freedom spinal unit, a female unit, whole body response testing and verification, and further testing in anticipation of government acceptance. In order to accomplish the task with the highest degree of success and scientific ability, the offeror has assembled a team of consultants that are World renown in the field of spine and impact biomechanics.

Title:Thermasorb Enhanced Microclimate Cooling Suit
Abstract:Chemical/Biological (CB) protective ensembles impose a thermal burden on aircrew, which not only limits mission time but poses a physiological danger to aircrew in even moderate operating environments. The thermal loads placed on these personnel may be reduced through the use of microclimate cooling systems. Unfortunately, to provide effective cooling, such systems must usually make compromises in weight, portability, effectiveness, or comfort. It is possible to greatly enhance the cooling efficiency of microclimate cooling suits through the use of Thermasorb additives. Thermasorb additives consist of micro-encapsulated phase-change materials that are capable of absorbing large amounts of heat without changing temperature. These additives can improve microclimate cooling suits through the use of modular cooling packs or a slurry-based system. Frisby proposes to design, build, test, and demonstrate three laboratory-scale Thermasorb systems. A system that incorporates bulk Thermasorb microcapsules in modular units that will absorb heat from a secondary circulating unit, a Thermasorb slurry system that will absorb heat directly from the heat source, and a hybrid (active/passive) system.

Title:Development of Fault Tolerance Analysis for Flight Critical Avionics Systems
Abstract:The objectives of this Phase I research are: 1. development of a set of metrics with both qualitative and quantitative attributes for evaluating capabilities of dependability modeling and simulation tools, 2. evaluation of representative dependability modeling and simulation tools in terms of the developed metrics by both analytical and experimental approaches, 3. Identification of essential features in modeling military fault tolerant computing systems and for commercialization, and demonstration of a theoretical basis for modifying existing tools or developing new tools with a potential for commercialization and for integration with a performance modeling tool. Two approaches will be used in the evaluation: analytical evaluation, mostly based on the user's manual, and experimental evaluation by execution of the tool. In the experimental evaluation, the representative tools will be used to model actual fault tolerant systems. The results of this Phase I research will be a high- level design for modifying selected existing tools or developing new tools. The design will form the basis for the Phase II development of tools that are suitable for both modeling military fault tolerant systems and commercialization.

Title:Passive Acoustic Sensor System for Marine Mammal Detection
Abstract:Protecting marine mammals from harm during Navy explosive operations is a high priority. A dedicated sensor system for field mitigation that has a high probability of detection, is flexible and can be tailored to fit the scope of an exercise is highly desirable. A preliminary examination of the characteristics and behavior of marine mammals suggests that a unique dedicated passive acoustic sensor system could be developed from existing sonobuoy technology. It would have near 100% probability of detection and would be a cost effective adjunct to the existing technique of visual observations. A program is proposed for the development of a passive acoustic sensor and processor/display system meeting those criteria. A comprehensive analysis of the vocalization characteristics and behavior of cetaceans and other marine mammals will be used to determine system characteristics for optimizing detection and localization. Frequency range, source level, conditions that induce vocalizations and variety of sounds will be important criteria. Omnidirectional and directional sensors will be compared for detection effectiveness, complexity, number of sensors required and cost. Various processing schemes will be evaluated to determine the most effective method of detection and localization. The goal is to develop a practical, simple, cost effective and flexible system.

Title:Magnetic Anomaly Detection (MAD) Geomagnetic Reference Sensor
Abstract:Dynamics Technology, Inc. (DTI) will develop and build a prototype geomagnetic reference sensor system (GRSS) to support advanced magnetic anomaly detection (MAD) for airborne submarine search. The GRSS is an off board system consisting of the reference sensor, auxiliary sensors for noise reduction, a sensor platform, and signal processing and noise reduction algorithms. It will suppress geomagnetic noise increasing the performance of airborne MAD. DTI has identified candidate sensors, auxiliary sensors, platforms, and signal processing and noise reduction algorithms. The candidate platforms are UAV, balloon, or buoy. Each platform has different sensor, auxiliary sensor, signal processing, and noise reduction requirements. A thorough system analysis will reveal the optimum GRSS from among the various candidate systems, and also demonstrate its feasibility. The primary measure of effectiveness will be cost per unit search area. The system analysis will build on DTI-developed system performance tools developed under previous Navy programs. Only after identifying the optimum GRSS will we assemble a prototype development team from the possible hardware vendor partners identified in the system analysis. In Phase 1 we will: (1) perform system analyses based on existing DTI models, (2) identify and characterize candidate sensor, platform, and processor systems and their operational constraints and costs in cooperation with potential vendor partners, (3) demonstrate system feasibility by modeling performance of a system based on identified components using best available sensor platform characteristics and a suitable processor mockup, and (4) determine Phase 2 prototype development requirements and vendor partners based on the feasibility analysis.

An analysis will be performed to assess expected registration performance and quantify acceptable image parameters. Spectrally insensitive algorithms will be developed by employing an Automatic Terrain Classifier (ATC). Feature attribute matching techniques will be employed to overcome differences in image scale and orientation. Phase II will extend the techniques to process images with significant perspective distortion and to perform 2D-to-3D image registration. TSC will leverage existing ATC software developed for DARPA, photogrammetry experience gained during urban database development contracts for the FAA, and general classification techniques developed during numerous efforts. In addition to any Government supplied imagery, existing SAR, IFSAR, Landsat and aerial photographic imagery will be employed to support algorithm development and performance evaluation.

Title:Signal Processing and System Concepts to Exploit Passive Signals in Airborne Active ASW Missions
Abstract:Future Airborne ASW tactics will depend heavily upon the use of active sonar and bistatics with a distributed field of sonobuoys as the primary means of initial target detection and localization. However, the bistatic detection and classification problem is compounded by short contact times, evasive target maneuvers, and the ambiguous nature of target echoes and clutter. Recent studies indicate that some target signals are potentially exploitable by passive detection, even in the acoustic and tactical environments of interest for active search. A method of detecting these signals, and a method of incorporating the clues provided by such detections, is desired to augment the information obtained from the processing of the active sonar data. A system level approach to achieving this passive signal detection, and implementing the techniques in an Air ASW active search mission is proposed.The proposed techniques will demonstrate that the passive detection methods are useful, and that they provide added value to current and future active search based Air ASW missions.

Title:Hyperpixel Sensor
Abstract:Technology is still a long way from packaging an electromagnetic sensor as efficiently as the eye of the mammal. This is especially true in the mechanics of focus, iris control, and pointing. However the eye is a good model for the features which should be emulated in a next generation sensor. Electronic and signal processing emulation techniques have already been demonstrated. As higher and higher resolution sensors are implemented an electronically steerable fovea can be contemplated in a wide field of view optical system. This combined with on and near the focal plane processing could provide a sensor with eye type capabilities. Those include: wide field of view, staring sample rates, image resolution enhancement through saccadic motion and image motion compensation, spatial and temporal pre-filtering, and fovea resolution enhancement in the area of most interest. ISC plans to architect such a sensor in the Phase I program using its Z-technology focal plane architecture and Vector Image Processor technology for signal processing. A novel on focal plane pixel summing (hyperpixel) technique will be used for the majority of the focal plane array in order to reduce output bandwidth, except in an electronically steerable fovea area where high resolution is required.

Title:High-Performance Network Interface for Advanced Avionics Architectures
Abstract:Group 16 Research and Development proposes to research and demonstrate the feasibility of developing new low-latency, high-throughput network interfacing elements that will permit next-generation avionics systems to exploit high-performance computing and communications in an efficient, scalable, portable, and interoperable manner with independence between applications and interconnects. The interfacing elements will consist of a novel hardware interface between the processor/memory bus and gigabit network, and lightweight channel software working with the hardware in support of distributed and parallel applications. The hardware interface will be designed to achieve on the order of processor-memory bandwidth or interconnect throughput, whichever is less, to support a high-performance commercial interconnect standard such as Scalable Coherent Interface, Fibre Channel, or Serial Express, and to support a high-performance processor architecture such as UltraSPARC, PowerPC, or Pentium-II. The software interface will be designed to provide lightweight communications, interoperability, and portability across message-passing and shared-memory, and support distributed and parallel processing mechanisms including CORBA-compatible object request brokering and POSIX-compatible, low-latency multithreading. A new and unique integrated simulation environment will be used to model the processor, network, and software architectures with high fidelity to match performance characteristics in order to achieve optimum throughput, latency, and system cost.

Title:Imaging LADAR System with Ultra High Speed Range Acquisition
Abstract:In the almost three decades since its inception, laser radar has progressed from cumbersome laboratory prototypes to reliable field systems. LADAR systems are currently based upon either a pulsed, time of flight measurement technique or a coherent detection scheme. Time of flight measurements systems are effective but suffer from limited spatial resolution and susceptibility to target camouflaging techniques. The coherent modulation technique offers many advantages including increased signal to noise ratio, simplified light sources and a higher immunity to multi-pulse camouflage methods. To date, the primary limitation to the coherent receiver concept is the availability of high speed, low noise detectors which offer a reasonable range, spatial and gray scale resolution. SMD proposes the development of an imaging LADAR that is capable of operating at 2,000,000 fps, and storing 16 images at 256 x 256 resolution. The detector and source are illuminated to form a coherent imaging LADAR system that measures range by modulation of both the source and intensifier gain. The sensor package can be fitted with a filter system to provide multi-spectral LADAR imagery for diverse applications including standard range measurements, atmospheric constituency information, and direct wind detection.

Title:Weapon System Operator Tactical Operation Aids
Abstract:Develop the combined use of voice commands, tactical decision aids and cueing as a form of Tactical Decision Aids (TDAs) to increase weapon system operator performance in high work-load scenarios. The combined enhancements to a weapon system have the potential to significantly reduce operator workload while increasing the Weapon System Operator's (WSO's) ability to react and proact to potentially hazardous situations. Research is needed to: Determine the basic tactical functions to be employed using the voice recognition system; Determine the best cueing methods and under what circumstances they should be initiated; Determine the TDA's that should be developed and how they should be initiated and modified in real-time; Determine the enhancement of operational effectiveness feasible for mixed cues using new technologies. Seminal research will be continued in the determination of cueing operational effectiveness of the outer to inner ear transfer and the Head Referenced Transfer Function that is critical to the faithful 3-Dimensional (3-D) audio cueing human experience. A Natural Language Speech (NLS) recognition and synthesized speech interface will be matched to suitable tactical operations to demonstrate the effectiveness of this intuitive interface. Message annunciation, situation oratory, decision prompts, alerts and warnings are part of this significant speech supported TDA. Unique to the research is the investigation and utility of using WSO initiated voice commands for tactical software function initiation in conjunction with TDA's and operator cueing for high interest action and in critical situations. A natural language interface that supports human computer dialog for ready identification and remedy of critical situations will benefit from the combination of speech recognition, speech synthesis and 3-D audio technologies. Innovative knowledge management techniques will be used to convert the C2 situation information into decision relevant knowledge. These knowledge management tools are an innovative part of the TDA which can relay "know-how" to the WSO through the spoken dialog interface.

Title:Low Cost, Light Weight Optics for Improved Multi-Function EO Sensor Performance
Abstract:Lighweight, stable, and stiff electro-optical sensor telescopes are required to increase performance and reduce life cycle costs of fixed wing, helicopter, ship, submarine, and man-portable tactical applications. The sensors provide color TV, NIR TV, laser ranging and designation, and MWIR plus LWIR imaging and tracking. The sensors must operate at multiple wavelengths through a common aperture and require wide field-of-view, all reflective, off-axis optics. The limitations in thermal stability, weight-savings and cost that are associated with current aluminum telescopes can be overcome by using carbon fiber reinforced composite material in con-junction with optical replication processes. The goal of this SBIR project is to significantly reduce the life cycle costs of sensors and improve their system performance and usefulness by introducing thermally stable, high stiffness, low density material. This goal will be addressed by designing, developing, manufacturing, and testing sample mirrors and a composite afocal telescope for LRAS3. Our plan is to install the new all-composite telescope in an existing LRAS3 electro-optical sensor, evaluate its performance, and directly compare it to the current diamond-turned aluminum reflective assembly. COI anticipates that the telescope will be considerably more stable thermally, lighter, optically comparable, and cost effective relative to the aluminum version.

Title:Environmentally Adaptable Detector/Classifier
Abstract:Environmentally robust detection and classification aids are critical to the ASW search mission in order to assist in decision making and reduce operator workload. In future multi-static, multi-receiver search missions, the number of alerts is expected to increase dramatically. An operator will simply not have the time to manually analyze and classify all the target and clutter returns without an algorithm to assist him. The goal of this SBIR effort is to develop environmentally robust algorithms that significantly increase detection and the ability to discriminate target returns from clutter, and ultimately reduce the operator workload. Many past efforts have been all-or-nothing ventures. Either the operator does it all by himself, or the algorithm completely replaces him in his effort, or at best has no interaction with him. A major problem with previous automated systems is that when the classifiers are exposed to a new and unknown environment, they suffer a drastic performance degradation. The effort proposed here will capitalize on information extracted in situ from initial insonification of the search area. Techniques are proposed to identify those echo return features which best exploit the current mission operating environment. Operator tools are proposed which keep him in the loop, reduce classification workload, and allow him to process large amounts of detections simultaneously.

Title:Advanced SAR Techniques at VHF (88-108 MHz) for Mine and Unexploded Ordnance Detection
Abstract:Airborne SAR systems currently exist and are used for wide-area surveillance and ground mapping. The majority of deployed systems have frequencies (400 MHz-30 GHz) which, in most cases, cannot penetrate the soil to the depth required for detection of buried mines and unexploded ordnance. Lower frequencies are required for penetration of the ground. However, in the lower parts of the frequency spectrum, the techniques and waveforms currently used to achieve SAR across-track range resolution, such as pulse compression or impulse waveforms, create major sources of wide-band interference to other systems when the radar is transmitting. Conversely, all other emitters operating in these crowded frequency bands cause significant levels of interference to the SAR radar receiver. Amelex proposes to investigate new SAR system components and waveforms to generate an RF signal with sufficiently low frequwency to penetrate the ground and with the ability to achieve the across-track resolution required while reducing the EMI on both transmit and receive.

Title:Wavelet-Based Detection and Classification for Shallow-Water Impulsive-Source Sonar
Abstract:In recent years the anti-submarine-warfare mission of the U. S. Navy has been expanded to include operations against stealthy, diesel-electric submarines operating in near-shore, shallow water regions of the world. Acoustic conditions in such regions are characterized by significant spatial and temporal variability. This variability reduces the performance of traditional sonar detection and classification algorithms. Impulsive-source active sonar systems can provide sufficient acoustic energy to detect these targets, but also produce significant clutter in a shallow--water environment. Detection of too many false targets can quickly overload sonar operators, so that true enemy targets are not detected and properly classified. Our proposed research will use a combination of wavelet and nonparametric bootstrap methods to achieve improved performance for detection and classification. Bootstrap methods allow one to adaptively estimate the underlying probability distribution of interference in the non--Gaussian colored-noise environment typical of shallow-water active sonar, and to set detection thresholds to maintain a desired false alarm rate. Subsequent target classification will be performed using wavelet representations of the sonar echoes, taking advantage of the time--frequency structure of targets and clutter. These representations may be combined with existing discriminant analysis methods. This work will demonstrate the feasibility of these techniques for sonar target detection and guide our phase II development of improved methods for detecting and classifying targets in the presence of clutter.

Title:Low-cost Micromachined Adaptive Optics Systems
Abstract:The "Low-cost, Micromachined Adaptive Optics Systems" SBIR program provides a path for bringing an innovative new technology to enhance tactical electro-optical systems such as laser designators, ladar, and infrared countermeasures. Schafer Corporation recently completed analyses for the Naval Air Warfare Center Aircraft Division that show the benefits of low-cost, low-weight, low-power-consumption micro-electrical-mechanical (MEM) adaptive optics in supporting Navy missions. Under the proposed effort, Schafer will design a lightweight, low-cost closed loop adaptive optics system which will have an integrated wavefront sensor, signal processor, and deformable mirror. MEM adaptive optics have weight and power characteristics that are two orders-of-magnitude less than conventional discrete actuator deformable mirrors. We will use the patented comb-drive MEM deformable mirror technology developed by our team member, SY Technology, Inc. Although some of the missions that were studied in the NAVAIR program will be considered in this SBIR, our emphasis here will be on MEM adaptive optics system design and assessment of the wavefront beacon concept, rather than a mission performance analysis. Schafer Corporation intends to have the technology developed and fully tested in time to impact the design of 21st Century tactical EO systems as well as supporting commercial applications in medicine, communications, and astronomy.

Title:Passive Target Velocity Measurement System
Abstract:This project characterizes and designs a sensor able to measure passive airglow reflections in a wide-field to detect anomalous velocity enhancements - the "PAR-WAVE" sensor. These velocity enhancements are caused by reflections of airglow emission features from fast moving objects. To achieve the required fast spectral integration, durability, and background rejection, the system features solid-state Fabry-Perot etalons using electronically tunable liquid crystals to achieve spectral line profile scanning. The feasibility of the proposed three-etalon system is evaluated by testing the transmission and spectral resolution capabilities of existing liquid crystal etalons, and by measurements of candidate airglow features using a conventional air-gap Fabry-Perot interferometer. The Phase I project delivers an optical and mechanical design balancing the field-of-view, spectral resolution, and sensitivity parameters into a device best suited for covert velocity detection in a cluttered atmospheric or littoral environment. The mechanical design permits selection of 2 - 4 spectral features depending on the field conditions, and permits two or three etalon operation optimizing throughput to daytime or nighttime background conditions. Laboratory and field-testing of extant, high spectral resolution liquid crystal etalons is a central feature of the Phase I initiative, permitting expeditious fabrication of a PAR-WAVE prototype in Phase II.

Title:High Bandwidth, Secure, Portable Wireless LAN
Abstract:An artful technical approach for achieving reliable >32 Mbps wireless transfer of integrated data, voice and video information is proposed. The technical approach utilizes 48 octet fast pack transport similar to as in ATM. The proposed wireless system provides network connectivity using legacy network interface standards (i.e. Ethernet, T1/E1, etc.) as well as through emerging network interface standards (i.e. ATM, SDH, etc.). To achieve high data rates, an artful solution to multipath propagation and its associated intersymbol interference is proposed. Novel waveform shaping techniques are utilized to gain spectral efficiency and highly linear modulators are used to prevent spectral blooming. Artful technical approaches are proposed to increase battery life (for a given throughput) by one or two orders of magnitude compared to presently available cellular telephones or 802.11 wireless LAN products. The use of a deterministic media access controller ensures low-latency (6 milliseconds) within the system and guarantees quality of service for the users of the system.

Title:Portable IFF Situation Display
Abstract:For safety of operation, Unmanned Aerial Vehicle personnel require a Situation Display that shows the position of the UAV and other aircraft in the area. For field operations the system must be manportable. The cost of the system must be affordable for this purpose. I-Comm, in cooperation with its partner Allied Signal Aerospace, has outlined a comprehensive Phase I project that will develop a Situation Display that is suitable for use by UAV operators in a field environment. The team has selected an existing interrogator/processor for the system and has identified a number of small commercial phased array antennas that may be adapted to meet the operational requirements. The major part of this effort addresses antenna selection, evaluation, and adaptation to meet the required operational capabilities and interface to the existing interrogator/processor. Additionally, modifications to existing software for display of the desired information on a laptop PC will be determined. The system configuration will allow augmentation for enhanced future capabilities.

Title:Repair Technique for Electroplated Surfaces
Abstract:A newly demonstrated technology (patent pending) provides a unique solution to repair of electroplated and other surfaces. The repair process permits the use of a wide variety of repair metals/alloys, is environmentally friendly, requires little/no cleaning of the breached surface, and can be applied in the depot or field (no special environment required) over many electroplate or other material surfaces. This replacement for electroplating is called Laser Induced Surface Improvement (LISI). Two years of laboratory development/testing have fully demonstrated its ability to produce a corrosion-resistant surface free from porosity and cracks. LISI can process hard-to-reach surfaces with laser energy transmitted via fiber-optic cable. The process can be used for touch-up of small areas or can process up to 50 sq. ft./hour with a 3 kw YAG laser. Further, the molecular bond of the repaired surface alloy resists all attempts at delamination or peeling and can accommodate a wide range of temperatures (coefficients of expansion). The result is a permanent thin layer of protective material (10 to 1000 microns with depth determined by controlled operating parameters). Phase I will demonstrate the applicability of several repair alloy formulations, investigate the integrity of the repair, and examine any effluents from the process.

Title:Decision Support Conversion System
Abstract:Intelligent Decision Systems, Inc. (IDSI) proposes to identify and define the parameters for a web-based decision support conversion system that will lead to the reuse and integration of existing instructional components to reduce the cost and lead time of developing, revising, and maintaining computer-based training systems (CBT). This conversion system will be designed to include the decision "tree" for identifying the feasibility of cost saving factors, the structure for locating existing media elements, and the possibility of the whole conversion system being web-based. This research addresses conversion of existing training assets into a dual use scenario through the use of a decision model that leads to a conclusion concerning conversion potential and availability of the asset. This will be accomplished through determining feasibility of implementing cost cutting strategies (e.g., a reuse strategy of graphics and other critical media elements to cut the costs of CBT development). A strategy for storage and retrieval of media elements along with identification of requirements for establishing the conversion system on the web. A proof of concept for applying the conversion system to development as well as revision of existing courseware will be provided.

Title:Content Addressable Graphics, Image and Video Retrieval Systems
Abstract:This proposal addresses development of a distributed image oriented storage and indexing architecture for building content searchable image databases (containing test, graphics, images, and digitize video). This is particularly difficult because computer vision has yet to solve the shape recognition problem which encompasses both text type and object type entities. Also, since substantial computation must be done to match image contents, substantial responsibility for the process must be delegated to the image archival engine (or in fact engines, because balancing data stored with computational elements is very important in this application as compared to more traditional text-oriented indexing and searching). In Cybernet's Phase I effort we will prototype a single node of the search engine and associated browser. Later we will scale the prototype product up for full scale Navy use.

Abstract:In phase I, we will investigate the use of Object Oriented technology and Computer Based Training (CBT) for the development of an extensible, visual, rapid prototyping environment for prototyping distributed, secure, part-task trainers. It is believed that through the use of a component model, a distributed object model, a portable programming language, a rule-based knowledge-base, and simulation and scenario based Intelligent Tutoring System (ITS) authoring utilities, such an environment can be realized. A well designed component model would make an extensible visual development environment possible. Portability can be achieved through the use of a highly portable programming language. Distribution can be achieved through a standard distributed object model. A rule and case based Expert System can be integrated into the system for the semi-automation of the prototype design process. Utilities for developing simulation and scenario based ITS's will further expedite the prototype development process. A small proof-of-concept prototype will be developed to accompany this research.

Title:Eye Tracker Using Bug Eye Orientation Sensor and Fuzzy Metrology
Abstract:Physical Optics Corporation (POC) proposes a new and innovative method of eye tracking, incorporating an Inverse Bug Eye Orientation System (IBEOS) in conjunction with fuzzy metrology to determine the orientation of an observer's eye. This eye tracking system can be applied directly to a virtual reality training system to determine the image resolution requirement so as to adjust the VR processing speed. In the proposed system, an invisible IR point source created by an optical fiber tip in front of the observer's eye creates a virtual image through Fresnel reflection from the cornea. Eye movement causes the virtual image of the point source to move. The IBEOS simply and rapidly determines the direction of the point virtual image of the light, and hence the orientation of the eye. The system is optical, and therefore immune to EMI and RFI. The BIEOS system is redundant, robust, and easily calibrated, so that it requires no operator training. The use of fuzzy metrology minimizes the influence of stray ambient light. The system can be installed in most environments (including vehicles) without modification.

Title:Aluminum-Nitride Infrared Window Materials for High Heat Load Applications
Abstract:Feasibility of fabricating IR window materials from aluminum nitride (AlN) will be demonstrated. Aluminum nitride windows are sought as replacements for sapphire windows on high speed seeker missiles because of their higher thermal shock resistance. Our approach is to consolidate high-purity ultrafine powders of AlN to obtain a nanocrystalline window. Small grain size is expected to minimize IR scattering, and preliminary data suggest this is the case. Theoretical estimates show that a grain size of 200 nm should yield high thermal conductivity and IR transparency. A novel aspect of this work is a flame synthesis process for producing ultrafine AlN powders encapsulated in a removable coating material to ensure that they retain their purity until consolidation. This sodium/halide flame and encapsulation technology is easily scaleable and the powders produced are unagglomerated and low in oxygen. We will also employ a novel consolidation process that sequentially removes the encapsulation material (sodium chloride) prior to vacuum hot pressing so that AlN powders are never directly exposed to atmosphere. For this program, ultrafine AlN powders will be synthesized and consolidated into 1 mm thick disks. Both powder and compacts will be characterized for IR transmission, elemental composition and crystal phases to determine the feasibility of using such materials for infrared transparent windows.

Title:Electrically Conductive Hard Coatings for Aircraft and Missile Domes
Abstract:Current IR systems are extremely susceptible to electromagnetic and radio frequency interference (EM/RFI) because they possess large apertures that present ideal front-door entry paths for EM radiation. Significant amounts of EM radiation (400 MHz - 18 GHz) can penetrate and couple to the IR sensor and supporting electronics, which leads to a substantial degradation in systems performance. EMI protection is critical to the survivability of the IR system and the system host (e.g., aircraft, satellite). Sienna Technologies, Inc., will investigate electrically conductive ceramics as erosion resistant EMI/RFI protective coatings for IR windows and radomes. We will deposit selected materials as continous film coatings by RF sputtering and study their shielding capability and IR optical transparency. Several compositions with different stoichiometries will be sputtered on window materials and heat treated. Resulting microstructures and sheet resistivities, optical transmission, and erosion resistance will be evaluated as a function of the composition and heat-treatment parameters. Deposition processes will be optimized to prepare test windows. Prepared windows will be tested for EM attenuation, IR transmission, and erosion resistance.

Title:High-Fidelity UCAV Simulation Station
Abstract:The Uninhabited Combat Air Vehicle (UCAV) is a new and promising multi-role and multi-mission system concept currently under development and evaluation by the armed forces. Similar to current generation of weapon systems, simulation of the UCAV mission profile will undoubtedly be an essential part of the system development process. Further, the rapid pace of their development and the evolution of various UCAV applications stress the need for expeditious optimization of air-to-air and surface attack tactical options in realistic combat scenarios using high-fidelity yet low-cost simulators. Advances in high-speed computer systems allow realistic simulation and assessment of many aspects of UCAV system, ranging from flight dynamics, ingress/egress profiles, sensor effectiveness, weapon tactics, and multi-vehicle coordination schemes. Furthermore, the maturity in personal computer (PC) systems makes them ideal for preliminary evaluations of UCAV systems previously addressable only by complex and expensive dome simulators. The proposed effort will further expand the application of offeror's current six-degree of freedom high-fidelity simulation capabilities on the PC's and provide Navy the unique capability to cost-effectively simulate and test UCAV air-to-air and surface attack maneuvering tactics and control paradigms in realistic combat scenarios. This submittal proposes to use a PC-based commercial off-the-shelf simulation environment, D-Six, developed under Air Force SBIR by the offeror, as the basis for the development of the UCAV simulation platform. The system will be leveraged by the many embedded development, analysis and networking features, significantly reducing the time and cost required for research, testing, demonstration and evolution of a viable multi-vehicle simulation platform.

Title:Accelerometer-Based Multi-Sensor INS
Abstract:Inertial navigation systems for airborne applications use three axis accelerometers and three axis rate gyros, and in many cases additional inputs using GPS and other sensors. The objective of the proposed work is to replace the expensive rate gyros with rate estimates based on multiple low-cost accelerometers. The error characteristics of the accelerometers, chiefly the bias stability and broadband noise, limit the accuracy and hence the application of the resulting accelerometer-based multi-sensor inertial navigation systems (AMS-INS). The technical challenges are first to predict the fundamental limitations using detailed error analysis, and then to design the hardware and embedded software algorithms needed to maximize the available performance. The proposed algorithms include robust statistical estimation, online identification of bias error terms using Kalman filtering or neural networks, and self-initialization of the rate estimates using measurements of centripetal acceleration. The Phase I effort will include a simulation test bed for AMS-INS development, single axis measurements, and both analytical and Monte Carlo error analyses. A hardware and real-time software design using 15 accelerometers, temperature sensor, and an embedded DSP controller will be performed in the Phase I Option.

Title:Shaped Charge Warhead Effectiveness Simulation Package
Abstract:We proposed to develop a personal-computer-based toolbox for the development of shaped-charge warheads. Given a shaped-charge configuration, this integrated set of analytical codes will predict the characteristics of the projected jet and its penetration and lethality performance in attaching complex armor systems and other targets containing modern countermeasures. At any stage of the analysis, warhead test data may be introduced for comparison or as the basis for subsequent analysis. In addition, a geometrical description of the warhead and armor system may be output in propoer format for hydrocode analysis. Predicted jet positions and penetrations will asist in the interactive preparation of warhead test plans. The toolbox will be integrated within a seamless, easy-to-use graphical user interface in a Windows-95 environment.

Title:Wideband Fine Frequency Measurement
Abstract:This proposal addresses Phase I of a multi-phase effort to develop advanced frequency-measuring equipment for use in ESM and ECM systems. Wide instantaneous bandwidth, fast response, and ability to handle overlapping signals are receiver requirements that reflect the increasing sophistication of hostile radars as well as today's dense signal environments. Currently available Instantaneous Frequency Measurement Receivers (IFMR) have the desired instantaneous bandwidth and fast response, and are relatively small and lightweight. However, they lack one key characteristic: they cannot determine the frequencies of two or more simultaneous signals. The proposed effort is designed to eliminate this restriction and to provide IFMRs with multi-signal measuring capabilities. Phase I will be based on the MUltiple SIgnal Classification (MUSIC) algorithm developed by the Chief Investigator and on his US patent that showed how the algorithm can be used with an IFMR of novel design to measure the frequencies of simultaneous input signals. An experimental IFMR with appropriate characteristics is available for this project. During Phase I we propose to do extensive testing to validate our analytical work and to investigate the effects of parameter variations and of RF or IF limiters.

Title:Wideband Fine Frequency Measurement
Abstract:Rapid unambiguous signal analysis of the electromagnetic spectrum by tactical ESM and ECM systems has become progressively more challenging due to the proliferation of high duty cycle radars which produce multiple simultaneous signals at the target platform. Severe problems arise when the band-of-interest contains a large number of signals of different amplitudes and types of modulation; the difficulties are compounded if the signals are pulses of relatively short duration. Most of the threat parameters used for sorting can now be changed on a pulse-by-pulse basis and the frequency of a signal may even be shifted or spread within a pulse. This Phase I effort addresses the development of a receiver which has an enhanced capability for measuring the frequency in high signal density environments in addition to the other key parameters (PW, PRI, and potentially AOA) that significantly upgrade overall system performance. Acousto-optic-based channelized receiver technology is a prime candidate for consideration. The major advantage of threat analysis using acousto-optic Bragg diffraction is the inherent capability for wideband spectrum analysis on a real-time, wide-open basis with good frequency resolution. The proposed effort will examine candidate AO-based architectures and develop a demonstration breadboard.

Title:Direct RF Signal Measurements using Digital Signal Processing
Abstract:InterSpace, Inc. proposes to design an instrument to directly measure Radio Frequency (RF) signal parameters using Digital Signal Processing (DSP) techniques. The proposed method will directly yield frequency and relative phase and amplitude measurements of broadband mutlispectral signals. Recent introductions of digitizers and processors, operating at GHz bandwidths have the potential to make this approach feasible. InterSpace, Inc. has developed several proprietary algorithms that can instantaneously measure closely spaced frequencies. These techniques have the advantage of low latency measurements useful for tracking signals and measuring signal jitter.

Title:Wideband Fine Frequency Measurement (FFM) by Pipelined Digital FFT Apparatus
Abstract:Recently available commercial digital chip technology makes it possible to offer NRL a digital fine frequency measurement (FFM) spectral analyzer design based on the fast Fourier transform (FFT) that meets or exceeds the measurement specifications posed by this SBIR topic. A VME card-based configuration is proposed that performs a 500-MHz bandwidth analysis with a 90-dB dynamic range, a 2-microsecond analysis time (throughput latency), a frequency resolution 1/1 024 of the analysis bandwidth (488 KHz), and a pipelined arrangement that permits a new FFT to be started every 0.5 microseconds (sustained 10 mega-pulses-per-second throughput). This 500-MHz analyzer is estimated to fit on four 6U VME cards using a combination of two unique VME card designs in its un-pipelined configuration (.5 Mpps throughput) or twenty VME cards in its pipeline configuration (10 Mpps throughput). The design concept can be arranged in a second configuration that performs a 1-GHz bandwidth analysis, which is estimated to fit on eight 6U VME cards using a different combination of the two VME card designs. A digital design offers several advantages over analog power spectral analyzer designs, such as acoustooptical approaches, including stability, no need for calibration, and additional analysis output such as the phase spectrum (which is not produced by analog designs).

Title:High-Bandwidth GBS-Based Software Download System
Abstract:Current methods of software deployment for shipboard computing assets are slow and exceedingly expensive. In the past, the lack of low-cost, global, high-bandwidth digital communications mandated the manual transportation of physical media to individual ships. With the emergence of the Global Broadcast Service (GBS), there is an opportunity to realize substantial cost savings by automating the software-distribution process while significantly reducing deployment time. This proposal suggests a secure, efficient system for end-to-end software distribution between a land-based software support agency and shipboard computing assets using GBS; this system is known as the satellite IP-based high-bandwidth software distribution system (SIPHON).

Title:Real Time Software Upload/Download via Satellite
Abstract:Delivery and installation of software onto Navy platforms typically requires that an installation team travels to the site and physically accesses the target computer system. In an environment of smaller budgets, this expensive and time-consuming process has become impractical. The Navy needs a system whereby a Software Support Agency (SSA) can transfer software directly from its offices to shipboard computers, regardless of the ship's location. SYNETICS proposes to satisfy this need by designing a General-purpose, Automated Delivery, Installation, and Validation (GADIVA) tool that will support the Configuration Management (CM) processes of both the SSA and the ship. SYNETICS will use an existing satellite link to the ship while targeting the more accessible Global Broadcasting System (GBS), available within the next couple of years. SSA-resident GADIVA will transmit an encrypted and verifiable software package that is archived by the shipboard GADIVA for installation under ship's control. Installation will be a cooperative effort between the target computer system and the shipboard GADIVA. SSA CM databases will be available through GADIVA using Relational Data Base Management System (RDBMS)-based Internet browser technology, allowing remote database queries, software requests, and delivery/installation status reporting. These capabilities will make GADIVA an effective delivery tool for diverse programs.

Abstract:The proposed Phase I project will examine low cost, low density composition gradient materials for zero-erosion rocket nozzles for use at the extreme temperatures encountered with aluminized propellants. The materials system consists of a C fiber-reinforced HfC matrix composite substrate overcoated or infiltrated with WC and finally coated with high purity W metal. Cylindrical geometry substrates will be produced via liquid infiltration/pyrolysis techniques. Surface layers will be produced by chemical vapor deposition on the inside of the cylinder using an existing apparatus. Screening tests will be performed to verify physical and mechanical properties. Specimens for erosion testing will be provided to the sponsor. Analytical studies of environmental effects on the composition gradient materials and self-degradation reactions such as C transport will support the experimental studies. In an optional task, C-HfC nozzle substrate material will be coated with Re instead of W.

Title:Lightweight Non-Eroding Throat Assembly for Solid Rocket Motors
Abstract:Solid rocket motors are used extensively in commercial, government, and military applications. The flame temperatures produced by these motors can exceed 3315C (6000F). Unfortunately, this temperature is well above the melting point of most materials, leaving only a select few from which solid rocket motor throats can be fabricated. In current throat designs, throat erosion is an accepted reality. In the proposed project, Ultramet will fabricate a non-eroding throat assembly by combining a tungsten inner wall with an innovative heat removal mechanism based on open-cell tungsten foam. The heat removal system will be entirely passive, and will be capable of restricting the tungsten inner wall temperature to a sufficiently low level to avoid erosion.

Abstract:The Navy has an objective to develope technology for active phased arrays where the transmitter source utilizes Microwave Power Modules (MPMs). The use of MPM-driven phased arrays offers the potential of eliminating cooling (required by most active solid-state T/R modules), and reducing weight, size and cost. TSC proposes a design architecture approach tha can efficiently implement the distribution of the MPM power output over selected apertures, or portions of an aperture. Tradeoffs and analyses will be directed toward the design of an MPM-driven phased array for the Navy's Cooperative Engagement Capability (CEC) antenna. The end result of the Phase I effort will be a feasibility assessment based on the estimated performance, weight, size, and cost of the selected MPM phased array design. Also, Phase II plans for the fabrication and demonstration of the MPM-driven antenna will be provided at the end of Phase I.

Title:Robust Target State Estimation Using Adaptive Maneuver Models
Abstract:Improvements in homing guidance laws and high performance autopilots are expected to enable the interception of fast, maneuvering, stealthy targets. However, the full potential of these systems can only be realized if the target states can be accurately estimated. Traditional methods for target state estimation using Kalman filters based on white-noise driven models may not be able to deliver the accuracies required to achieve hit-to-kill capabilities. This proposal advances a target state estimator incorporating an adaptive maneuver logic system. Using the seeker measurements, and a transformed model of the target, the proposed estimator will determine the target maneuver strategies on-line while generating accurate state estimates. Phase I research will establish the feasibility of the proposed target state estimator, and compare its performance with a conventional Kalman filter-based target state estimator. This evaluation will be carried out using a six degrees-of-freedom missile simulation incorporating a high performance autopilot and an advanced differential game-based homing guidance law. Phase II work will focus on developing a target state estimator for the Navy Standard missile, evaluation in several different scenarios of interest to the Navy and on developing code for real-time, on-board implementation of the target state estimator.

Title:Robust Adaptive Target State Estimation for Missile Guidance using Interactive Multiple Model Kalman Filter
Abstract:The accuracy and robustness of target state estimators to target maneuvers and varying target characteristics have been one of the limiting factors to improving the interceptor's terminal performance and direct hit capability. This effort will examine techniques to improve the accuracy of the onboard target state estimators, and thereby improve the miss distance performance of homing interceptors. The solution proposed here to improve tracking performance is based on the Interacting Multiple Model (IMM) Kalman filter estimator which has been used successfully by Scientific Systems for ship-board radar target tracking of highly maneuvering targets under ECM and clutter conditions. The IMM Kalman filter can handle target maneuvers with a significantly smaller estimation error and track loss rate compared to a single Kalman filter. The IMM-KF has proven to be robust and extremely fast in maneuver detection. We will consider both active and passive tracking of targets by the interceptor. The active tracking problem is similar to the one considered earlier, but the passive or semi-active LOS tracking problem is non-linear and poorly observable. We will use an approach by Jauffret and Pillon (1996) to linearize the measurement equation, and investigate the effects of using an accurate initial position estimate obtained by a radar. We will also investigate the use of sparse active measurements and their effect on the tracking performance. The combined performance of an Adavance Guidance Law (AGL) and IMM-KF algorithm will be evaluated using the simulation of a navy interceptor missile. Prof. Y. Bar-Shalom, a leading authority in the field of estimation and target tracking and one of the developers of the IMM-KF algorithm will provide support to the project as a consultant.

Title:Robust Adaptive Target State Estimation for Missile Guidance
Abstract:Interceptor missiles have traditionally used PN (Proportional Navigation) for terminal homing guidance. However, modern threats have become faster, more stealthy, and more maneuverable. Terminal homing missile performance requirements have also become more stringent, such as for direct-hit capability. These requirements have led to the development of newer guidance laws to improve terminal homing performance. These newer guidance laws typically use additional information (e.g., target acceleration) not required for PN. The state estimators providing this information must produce accurate estimates, otherwise the performance of the newer guidance laws can degrade to the point where there performance is worse than conventional PN guidance. The accuracy and robustness of the state estimators have been some of the limiting factors for improving terminal homing performance via the use of newer guidance laws. TSC is proposing the development of robust and adaptive state estimators based on the Interacting Multiple Model (IMM) algorithm for use in onboard terminal homing guidance. The IMM algorithm is a self-adjusting variable bandwidth filter, which makes it robust and adaptive to target maneuvers. TSC will develop a six degree-of-freedom missile simulation, develop the IMM estimators, implement a newer guidance law utilizing these state estimates, and conduct a series of Monte Carlo simulations to quantify the performances of the IMM estimators against various types of targets and maneuvers.

Title:Real-Time and Fault-Tolerant Open Architecture for Combat Systems
Abstract:We propose to develop a layered real-time and fault-tolerant CORBA-based software architecture as a means to realizing an open standards-based middleware for Naval combat systems. The key features of our approach are (1) a low-level interface to a distributed network infrastructure consisting of an integrated real-time and fault-tolerant extension to CORBA patterned after existing and emerging CORBA standards and implemented using research and industry prototypes (i.e., Electra, TAO, and Orbix+Isis), (2) a higher-level interface built on this infrastructure and adapted to the requirements of combat systems (i.e., Aegis and CEC), (3) component-based archetypes of key reusable software objects (i.e., timed event channels), and (4) semi-automatic migration techniques for CMS-2 and ADA legacy systems, in terms of both reengineering using CORBA wrapping techniques as well as direct translation. In Phase I of this research we will investigate the feasibility of the above approach and its alternatives, leading to a well-defined high-level interface, the definition of several key component-based archetypes, and the design of an integrated real-time and fault-tolerant infrastructure leveraging existing implementation vehicles. In particular we will address the role of Java in real-time CORBA-based systems, and the use of component-based models both in design as well as in migration of legacy systems. The use of distributed object technology such as CORBA is, we posit, vital to any approach for developing a middleware supporting interoperability, and nascent lightweight CORBA extensions, while still unintegrated and low level, have great potential. Our efforts seek to fill the gaps posed by these currently missing vital technologies, and will significantly advance the realization of a high-level open architecture for combat systems.

Title:Combat System Software Migration to Open Systems
Abstract:The objective is the creation and development of the "Ageless Combat System" through the identification and design of a Combat System Tactical Common Operating Environment (CSTCOE). DSR proposes a CSTOE based on a Combat System Middleware Standard (CSMS) that will enable innovative use of middleware software as both a breakwall and interface between combat system software applications, operating system(s), and platform hardware and communications systems. This use of middleware will enable transparent communications between application tasks/processes on distributed operating systems and hardware over a heterogeneous network of computers. The independence and portability of the software applications from the hardware and communications systems will enable technical refreshment of legacy systems and insertion of new hardware and software to the combat systems at costs significantly below current levels. This approach also can be used to expand the use of select combat system software applications, such as CEC, to other platforms participating in Joint Theater Air Missile Defense (JTAMD) on the Joint Composite Tracking Network (JCTN). These platforms would be both airborne (such as E2C, AWACS) and ground based (such as Patriot, THAAD, CSAM/MEADS, or TAOC).

Title:Combat System Software Migration to Open Systems
Abstract:Solipsys Corporation has significant experience integrating legacy military software with modern "open-environments." This is exemplified by the middleware approach demonstrated during the All Services Combat Identification Evaluation Team (ASCIET) '97 exercise in Gulfport, Mississippi, which has since been extended to a more global framework. Solipsys engineers have an extensive background in combat system integration, gained over many years of experience with the Cooperative Engagement Capability (CEC) and related systems. We will examine the current and evolving middleware solutions available in industry for their applicability to military systems. Our recent experience includes designing interfaces to an Arsenal Ship C4I environment using legacy and new systems, where CORBA, DCOM and Java were candidates. This gives us a quick start advantage in designing a middleware solution to solve combat system specific problems arising from integrating legacy and new software. Phase 1 will document this approach and begin the planning for Phase 2 when the middleware recommendations will be implemented into AEGIS.

Title:Low-Cost Hybrid Rocket Nozzle Fabrication Methods
Abstract:Rayon based materials have shown excellent performance for rocket nozzle applications. In addition, conventional tape wrap methods for fabrication have been successful to obtain the required component strengths. However, with the current lack of a domestic rayon supply, a low-cost replacement is desperately needed. Foster-Miller has previously demonstrated a low-cost fabrication technique for tape-wrapped rocket nozzle components. This method of in-situ braiding and nozzle wrapping has successfully achieved the high performance and low-cost requirements for such applications. As an adjunct to this technology, Foster-Miller proposes expand the braiding process to include the capability to create hybrid flat tape. This triaxial braid will have carbon bias fibers on one side of the braid, and glass bias on the other, with the two fibers interlocked at the interface. The system will tailor the thermal conductivity so that the material system has the carbon's ablation resistance with the glass insulation capabilities, while maintaining the structural performance requirements. Foster-Miller's Phase I teaming partner, Thiokol Corporation, is eager for the development of such a low-cost process for current rocket nozzle exit cone applications. The successful development of this novel technology will provide a robust, low-cost alternative to rayon which can be easily implemented into existing rocket motor technology.

Title:Improvements to the Vacuum Power Booster in Microwave
Abstract:Microwave Power Module (MPM) applications would benefit from improved performance characteristics such as increased electrical efficiency, reduced cooling requirements, and reduced size and weight that are largely determined by the performance of the vacuum power booster MPM component. Technology Service Corporation therefore proposes to improve Microwave Power Module (MPM) performance characteristics by inserting a novel recently developed cold cathode material in the vacuum power booster that (1) eliminates the need for heater filament power and (2) offers the potential to pre-bunch the electron beam, thereby improving the rf efficiency and gain of the power booster. Three subtasks will be performed during Phase I. (1) The cold cathode material will be tested in a planar diode configuration to establish its DC and AC electron emission characteristics, leading to a cathode material electron emission model. (2) This emission model will be used with standard vacuum power booster design tools to analyze the potential improvements this cathode material will have on power booster efficiency and gain. (3) A simplified experimental gun structure will be built and tested for emission and modulation characteristics.

Title:A Multi-Level Network (MLN) Approach to theater Battle Management Operations (TBMO)
Abstract:The objective of this effort is to use an innovative software approach that will link together existing distributive, sensor and tactical information networks. This software approach will enable on-demand communications connectivity in a seamless MLN environment that can be used in TBMO. DSR proposes the use of software algorithms to perform a Mapping/Data Distribution Node (MDDN) function on Command and Control (C2) platforms such as the E-2C, the Mission Control Element (MCE), the Airborne Warning and Control System (AWACS), and other Naval weapon systems. The MDDN function will conduct priority exchange of select battle data between units on sensor netting networks, command/planning networks, and tactical communications networks. The exchanges will be both horizontal (reach additional slensor or shooter platforms) alnd vertical (across networks) to reach various command levels. DSR will determine the ability of shooter platforms to use Cooperative Engagement Capability (CEC) composite tracks and/or select CEC sensor/track data and the timelines required for the information exchange, as well as the ability of current information networks to exchange this data. The software process will determine the best communications path available in the current operational situation, apply routing and prioritization instructions, and map/parse shooter data into appropriate message formats for recipients. The stacked and branched, open architecture network designed in Phase I will be prototyped in a Phase II proof of concept demonstration.

Abstract:We are at the genesis of a set of new, innovative, DoD development efforts such as Sea Athena, the Extended Littoral Battlefield (ELB) ACTD, the US Army Aerostat Development Program, the Battlefield Awareness and Data Dissemination (BADD) ACTD and the DD-21 program, each with its own set of overlapping connectivity requirements. The opportunity and demand exists for development of a set of core, enabling components that would form the basis of a Multi-Level Network capability. Specifically required is the introduction of an extensible data synthesis processor coupled with adaptive, intelligent data distribution and routing management.

As a result of this effort, we will develop an open sensor/BMC3 architecture and concept of operations that would be scaleable as additional assets deployed to the developing theater. Using these products we will perform an analysis of this architecture, to evaluate the performance improvements to be realized by the MLN.

Title:Compact High-Energy Pulsed Chemical Laser
Abstract:Chemical Lasers are the most efficient lasers that can provide high-energy laser pulses at the mid-wave infrared (MWIR) and long-wave infrared wavelengths (LWIR). The utility of pulsed chemical lasers (PCL) has been limited by their size, weight and ruggedness. These limitations result from the technologies used to initiate the PCL. The initiators for PCLs have been principally electron beams and flashlamps. The electrical components for these initiators are large, heavy and fragile and therefore PCLs have not been fieldable as transportable systems. The solution to the problem of making a compact PCL is to replace flashlamps and electron-beam initiators with a rugged, highly efficient, initiator technology. The opportunity exists to use recent advances in surface-discharge initiators to make a compact, portable and rugged PCL. The surface-discharge technology developed by Mission Research Corporation (MRC) was successfully demonstrated by initiating a high-energy (1 kJ) chemical laser. This approach to PCL technology will fulfill the requirements for a compact high-energy infrared laser.

Title:PCMCIA Card to Cllect/Store Viration/Performance Data for Operating Machinery
Abstract:Vibration data collectors used for condition-based maintenance (CBM) programs are becoming standard practice in Navy and private industry. Current systems in use are based on proprietary hardware and software architectures. These proprietary systems are expensive to procure and support and are difficult to expand. Technical innovation is typically limited to the system supplier. Modern computer technology is enabling the development of nonproprietary open architecture vibration data collectors using a commercial off-the-shelf (COTS) portable computer system and a simple Personal Computer Memory Card International Association (PCMCIA) vibration data acquisition card. ORINCON proposes to develop a PCMCIA six-channel vibration acquisition system, vibration signal processing software, and suitable user interface for shipboard vibration acquisition, processing, storage, display, and communication. The proposed system utilizes state-of-the-art electronics found in modern audio equipment as a basis for the PCMCIA vibration acquisition card. A standard laptop computer running Window 95/NT provides the signal processing, data storage, and communication capabilities. Signal processing and display functions are implemented in RIPPEN*. RIPPEN* is ORINCON's unique open architecture signal processing middieware software that allows rapid development and portability of signal processing and diagnostic software. A MIMOSA compliant CBM database will be selected and interfaced with and a detailed specification of the system and signal processing demonstration will be conducted as part of the Phase I effort. A complete prototype will be developed in Phase 11.

Abstract:The LCAC Full-Mission Trainer (FMT) is providing a cost-effective tool for training LCAC operators in normal craft operation and casualty mode conditions. However, the FMT was never validated with full-scale LCAC test data. Rather, the feel of the FMT was "tuned" by adjusting tuning coefficients in response to inputs obtained from experienced LCAC operators. The FMT training schedule combined with modeling limitations prevents the U.S. Navy from conducting in-house analysis on the impact of atypical LCAC missions, unusual paylod items or craft alterations, for instance. PC-based computers and software simulation tools have now progressed to the point where physics-based time domain dynamic simulation of the LCAC is no longer limited to mainframe computers and, thus, can readily be performed on desktop computers. PC-based programs must also be validated with actual craft data to maximize fidelity. It is proposed, therefore, that a PC-based simulation of LCAC motions be developed and that the actual test data necessary for subsequent validation of the dynamic simulation be obtained. The intent of the proposed Phase-I work effort is to identify the required test data and develop a test plan and data analysis plan which can be used to efficiently obtain the test data necessay for simulation verification.

Title:Variable Virtual Combat Mock-up (VVCM)
Abstract:The DSR Team consisting of DSR, Logicon Syscon and the Institute for Simulation and Training (IST) proposes to develop the architecture and system requirements for the construction of an advanced virtual display designated the "Variable Virtual Combat Mock-up (VVCM)". The innovation of this architecture is the ability to introduce an easily reconfigurable, ship specific, fully interactive, individual console operator or Combat Information Center (CIC) team, combat system training device into a virtual environment, termed "augmented reality". A VVCM Concept of Operations (CONOPS) document, system design requirements and notional hardware architecture will be developed. The DSR team will develop an innovative design that will leverage existing, validated models, scenarios, and data bases as well as software available from S14A13 Tactical Advanced Simulated Warfare Integrated Trainer (TASWIT), Modular Semi-Automated Forces (MODSAF), Naval Semi-Automated Forces (NAVSAF), or other compatible, emulation-type, training software into the design of the VVCM. In addition, the DSR team will document the capabilities of state-of-the-art virtual reality devices such as head mounted displays to support this augmented reality environment. The DSR team will also develop two VVCM implementation options highlighting the cost vs capability tradeoff. The VVCM system options and training value added will be determined by conducting a cost/fidelity analysis based on the competing hardware/software architectures and the metrics for each. Phase II recommendations for implementing key components will be provided.

Title:Variable Virtual Combat Mock-up (VVCM)
Abstract:Sonalysts, Inc. proposes leveraging our Team's extensive research and development experience with state-of-the-art defense and commercial training and visualization technologies to develop an effective Variable Virtual Combat Mock-up (VCCM). Key Phase I objectives will include: defining the training concept of operations; identifying, assessing, and developing/applying the supporting required technologies; and finally, defining the architecture for the VVCM. Our focus will ensure training objectives for the virtual CIC/CDC team training system and a sound technical response are complimentary and technically feasible. A broad range of virtual technologies will be investigated to determine suitability to develop the flexible, reconfigurable virtual environment. Virtual reality (VR) technologies possessed by our proposing team and commercially available, will be assessed. The most promising will be applied to ensure our technical approach is effective and economical. To accelerate development and lower cost, we will leverage appropriate existing trainer architectures for the foundation of the VVCM. We will also exploit existing information resources, combat systems, and trainer architectures (e.g., Battle Force Tactical Trainer (BFTT), internet) to innovatively broaden the training opportunities presented by this topic area.

Title:Reconfigurable Computing
Abstract:Tanner Research proposes to develop a powerful and flexible reconfigurable computer and deliver a completely functional prototype by the end of Phase I. Because it will have a modular architecture, our reconfigurable computer will be significantly more cost-effective than traditional reconfigurable computers. Because of technological advances that have increased the logic density on a silicon chip, reconfigurable computers are better suited than custom ASICs for a wide range of applications. For example, unlike an ASIC, a reconfigurable computer can be easily and quickly modified from a remote location to upgrade its performance or even to perform a completely different function; hence, its non-recurring engineering (NRE) costs are reduced. Our modular architecture will further minimize NRE costs because it allows such costs to be amortized over an even larger domain of systems. In addition, upgrading a reconfigurable computer is easier and more reliable than upgrading an ASIC, because reconfigurable computer upgrades can be more easily developed, verified, and implemented. Because of our expertise developing reconfigurable computers, we will be able to deliver a complete prototype of the hardware in Phase I. In Phase II, we will refine the hardware design and develop a software development environment to further increase cost effectiveness.

In order to optimize speed, VisiCom will need to examine pipelined and paralled processing approaches. FPGA clock rates are generally below those of core logic parts. Care will be required since certain design implementations will actually cause clock rates to decrease. Designs spanning multiple FPGAs may be afflicted with further speed degradation.

Title:Hand Held Vibration Monitor
Abstract:Optiphase, Inc. proposes a highly innovative and unique approach to non-intrusive, non-contacting vibration sensing. This approach involves a fiber optic sensor implementation which opticaly performs differentiation of interferometric displacement data to obtain the desired velocity data. This completely unique approach is capable of providing accurate vibration measurements over ranges which significantly exceed that stated in the solicitation specification. During the preparation of the Phase I proposal, the proposed measurement concept was validated through laboratory experimentation. We propose, for Phase I to determine the feasibility of the proposed approach against the intended application, for hand held measurement of vibration data, inclusive of providing data storage and analysis. We expect to not only prove the feasibility, but to also show that the technology is manufacturable at half the cost of existing laser Doppler vibration systems without compromising measurement performance. In Phase II, we will develop and evaluate a prototype apparatus which accomplishes the solicitation objective. We expect a significant and immediate market for this innovative technology.

Title:Weighted Oceanographic Registration Mine (WORM)
Abstract:Omni Technologies, Inc. proposes to study the design feasibility of a sensor and data acquisition package to be used in the monitoring and collection of mine burial and mine burial forcing function data. The data will be used to improve military mine burial models to determine the detectability of buried mines and help define mine hunt training curriculums. The sensor and data acquisition package will collect and store data for three months with a default sampling time of once per hour. The design goals will include having minimal impact on environmental forces driving mine burial by placing sensors inside the mine or embedding them in the mine walls and to operate in any orientation and preserve the center of gravity, weight and target strength of an operational mine. The Phase I design/study will search for off-the-shelf (or slightly modified) sensors to measure acoustic energy, mine attitude, mine orientation, acceleration and water depth. Additionnally, two innovative sensors to measure percent burial and boundary layer water currents will be studied in Phase I and prototyped in the Phase I Option. A top level software design will be developed to provide for data storage, retrieval and display.

We shall use case based reasoning and association agents in identifying new links and relationships within data contain in shipboard information systems. Case based reasoning can be used to identify new links and relationships by looking at past similar events. For example, if a certain part is required on board ship that is currently out of stock, a case based system could identify a part that could be used in its place based on past events. Association technology looks at many types of different database transactions and identifies patterns. Association technology can be used, as an example, in logistics in tracking assets for a period of time.

Title:A Three-Tiered Mediation Approach to Virtual Data Integration
Abstract:Throughout government and industry, extremely large volumes of data are being stored with complex requirements in very heterogeneous hardware, software, and communications environments. Infograte, Incorporated has developed a robust software solution that allows users to transparently extract data stored across disparate and geographically dispersed heterogeneous databases from a single user-friendly interface. The software solution consists of a proprietary knowledge representation, development technique, and query processor. Infograte's representation employs a three-tiered extension of entity-category-relationship theory as the foundation for a global schema that models the logic of a virtual database federation. The development technique is an iterative methodology that is used to build the required global schema. The query processing algorithm follows a mediation approach to interpret the global schema and semantically translate queries across the distributed database federation. InfoGrate will apply its knowledge representation and development technique to the Navy's ship engineering data environment. The result will be a global schema that can be used with InfoGrate's query processor to virtually integrate the data. The technique will be applied by the Infograte research team, which has a successful track record of developing and commercializing database technologies.

Title:Non-Fouling Ultrafiltration Membranes
Abstract:Ultrafiltration membranes offer great potential for compact, low cost clean-up of Navy surface ship graywater and blackwater. A major limitation of these ultrafiltration membranes is significant loss in flux with time associated with membrane fouling from proteins, polysaccharides, and other waste products. Backflushing can only be used to a limited extent. Chemical treatments are undesirous since they pollute. ompact Membrane Systems, Inc. has developed unique low surface energy perfluoropolymer coatings. These perfluoropolymer coatings appear to be a universal non-fouling surface showing enhanced resistance to biological fluids (blood, platelets, SF-21, Vero cells) and oils and, therefore, should greatly enhance the ultrafilters fouling resistance. These perfluorocoatings represent a universal approach to enhancing ultrafilter resistance in that we have successfully coated numerous ultrafilters (polysulfone, cellulose, esters, polypropylene, PVDF). Preliminary results indicate that coating of ultrafilters with CMS perfluoropolymers can significantly enhance fouling resistance with little change in bulk flow. By using these perfluoropolymer coatings, we will enhance fouling resistance without introduction of chemical pollutants. In Phase I, we will: (1) coat various ultrafilters with our perfluoropolymers, (2) perform controlled internal laboratory evaluation of enhanced fouling resistance, (3) in conjunction with DoD, perform pilot operation with preferred candidate graywater, and (4) perform economic analysis based on results from (2) and (3). Objectives of Phase I are to demonstrate stable ultrafiltration capability in excess of 20 liters per square meter per hour using high density waste streams (15-20 grams/liter) for over 1000 hours of operation.

Title:In Situ Electrolytic System for Ultrafiltration Membrane Cleaning
Abstract:This proposed program focuses on developing a relatively environmentally benign technology for cleaning ultrafiltration membranes in naval surface vessels through the on-site electrolytic generation of hydrogen peroxide and hydrogen-peroxide-derived hydroxyl radicals. The approach will utilize novel bifunctional cathode electrocatalysts in a polymer electrolyte electrolytic cell for the efficient on-site electrogeneration of hydrogen peroxide and hydroxyl radicals within the wastewater stream. The radicals so produced will sterilize and digest organic residues to abate membrane fouling. The proposed technology will provide a compact on-site, environmentally friendly means of nondestructively removing organic and biological fouling from membranes utilized to treat non-oily graywater/blackwater on surface naval vessels.

Title:Cleaners for Wastewater Ultrafiltration Membranes
Abstract:A non-polluting efficient cleaning technology for completely removing clogging buildup and microbial biofilm from ultrafiltration membranes has been developed. The technology has been successfully applied to synthetic non-oily graywater effluent and should meet all regulatory standards for discharge. The technology should also be applicable to blackwater applications. It consists of three elements: innovative fluid dynamics, specific cleaning chemistry and efficient cleaning protocol. Emphasis is placed on removal of biofilm from the membrane surface as well as cleaning of the membrane pores. This proprietary technology completely removes biofilm and other foulants from membrane surfaces and reduces the cleaning time by a factor of 10 when compared with standard methods. Our design should interface with ultrafiltration treatment equipment on Naval ships without modification. PTTs cleaning chemistry is environmentally-safe and effective. Our development team includes Professor Audrey Levine of Utah State; she will direct efforts related to the gray/black water composition and assist in foulants characterization. Phase II will involve designing and building a prototype to incorporate into wastewater treatment systems on Navy ships. A complete marketing plan has been prepared for Navy and civilian applications. PTTs cleaning technology includes the cleaning of the lumen and pore of the tubular membrane.

Title:Co-Injection Resin Transfer Molding (CIRTM)
Abstract:Shipboard structures employing composites typically use glass/vinyl ester (VE) manufactured with vacuum assisted RTM. This composite system offers reduced weight, no corrosion and improved signature performance but lacks the fire performance characteristics required for shipboard use. Phenolic resins (PH) provide outstanding fire performance but are difficult to process and offer lower structural properties. No existing single resin system can meet all of the requirements in a given application for Naval shipboard structures. The co-injection resin transfer molding (CIRTM) process was developed by the University of Delaware and the Army Research Laboratory to simultaneously inject two (or more) resins into a dry composite preform maintaining discrete layers of resin through the thickness of the preform. Using CIRTM, a phenolic surface layer may be incorporated with a vinyl ester resin in a single composite part, improving fire performance while maintaining the cost, processing and structural advantages of the vinyl ester. Through this program, preliminary property characterization of fire-hard CIRTM components will be accomplished through the fabrication of 2'x2' test panels. In addition, we will demonstrate that the benefits of the CIRTM process can be scaled up for realistic Naval structural applications. In Phase II a half scale deck house will be fabricated.

Title:Co-Infusion of Multiple Resins for Enhanced Fire Resistance
Abstract:Composite structures are highly desirable for future Navy surface ships due primarily to their high strength to weight ratio, corrosion resistance and radar signature reduction potential. The recent National Research Council (NRC) study on technology needs for the 21st century (1) specifically cites the use of composite materials for signature reduction as one of the three primary development recommendations for Navy platforms. However, flammability/smoke/toxicity (FST) concerns have long hindered the implementation of composite structures into Navy warships and US commercial vessels. In the proposed Phase I program, Foster-Miller will evaluate and develop several options for co-infusion of two distinct resin systems into a single composite structure. A central performance goal of each of these options will be to provide the necessary fire barrier as an integral part of a composite structure while also yielding suitable structural performance and low manufacturing costs. Foster-Miller has previously demonstrated a unique intumescent composite matrix resin that provides improved fire barrier performance over standard phenolic resin systems. This resin system will be evaluated in the proposed program as one of the co-infusion resin systems. The proposed program will evaluate these options against the necessary performance specifications identified by Foster Miller and our team members Bath Iron Works and Techmatics. Following initial evaluation, a minimum of two co-infusion approaches will be carried through testing and evaluation against criteria including fire and structural performance, processability and cost. The program will culminate in the fabrication and testing of a sub-component to demonstrate the performance of the best approach during the optional phase of the program.

Abstract:Duke & Associates will develop a process/material modification for carbon fiber/vinyl ester composite materials which will provide enhanced fiber-matrix adhesion using a low cost, room temperature process such as resin transfer molding (RTM) or vacuum assisted RTM to manufacture high performance composite structures. The program goal is to increase the fiber to matrix strength to that of carbon epoxy or the strength of the matrix.

Title:A LOW COST INTERPHASE CHEMISTRY TO PROMOTE CARBON FIBER-VINYL
Abstract:Triton Systems, Inc. proposes to demonstrate a low cost interphase chemistry which will improve the mechanical strength of carbon fiber/vinyl ester composites by providing a polymer layer which bonds exceptionally well to both the carbon fibers and the vinyl ester resin. This interphase chemistry will utilize a Triton proprietary polymer applied to the carbon fiber surface and adhered to the surface through strong hydrogen bonding. The surface of the carbon fiber will be preoxidized to improve bonding to the polymer. This proprietary interphase polymer has also been shown to be miscible with vinyl ester resin, forming a single phase between the two polymers rather than a distinct, and structurally weaker, two phase blend. The polymer chemistry will be optimized for compatibility with vinyl ester resins using Triton Systems vast experience and database with these materials. In the Phase I program we will demonstrate the improved fiber/matrix adhesion via transverse tensile testing of unidirectional composites. In a Phase II program we will scale the process up to pilot production levels and demonstrate the technology on a large scale Naval component.

Title:Shipboard Airborne Noise Control Design and Diagnostic Tool
Abstract:In the 14 years since the last revision of SNAME's Design Guide for Shipboard Airborne Noise Control, acoustic prediction techniques and control methods have significantly improved. Current prediction techniques effectively utilize sophisticated computer programs. These could possibly be tied to CAD/CAE programs. NCE believes that the government, naval architects and shipyards can greatly benefit from these improvements. When properly implemented, this latest technology can improve the noise and vibration environment on all vessels. At the same time, associated adverse impacts on space, weight, maintainability of systems, and cost will be reduced. This process would also provide an integrated systems approach while reducing the effort needed to predict and control noise on-board vessels. Many of the approaches used in Statistical Energy Analysis can be easily coded and used by any engineer involved in the design process. Noise control treatment types and their expected effectiveness have also changed. These changes can be factored into various databases. Databases can be setup for machinery and equipment acoustic source levels; airborne, structureborne, and waterborne path transmission effects; and acoustic characteristics of materials used in shipboard constructions. This software would be very effective for predicting and reducing noise on all types of vessels.

The monitor will be designed as a small insertion probe, capable of being "hot tapped" into existing cooling water pipelines. Real time data generated by the probe will provide a means of monitoring and segregating both microbial and abiotic fouling deposit buildup. The probe will allow a means of simulating both heat transfer surface temperatures and tube/plate materials found in various cooling system heat exchangers. Correlation of probe microbiofouling data due to seawater cooling system fouled surfaces will be determined. The monitor, when utilized within a "feedback loop", with adjustable chemical injection pumps, will be able to accurately monitor and control microbiological and/or scale buildup within cooling water systems under changing water quality and operating conditions.

Title:Affordable High Performance Reinforced Polyurethane Shock and Vibration Mounts
Abstract:Seventeen (17) new constant natural frequency mounts can replace forty three (43) current Navy mounts. Constant Natural Frequency (CNF) mounts are currently used in millions of commercial and foreign applications, and improvements are offered in published and on-going research. The CNF concept will be adapted to Navy needs and the commercial market, which will help insure a Navy vendor base. Empirically- and analytically-derived elastomer shaped mounts yielding a stiffness proportional to the load and a constant natural frequency over a weight ratio of 1 to 9 have been demonstrated. An additional benefit of the new mounts is, because they are relatively insensitive to load, the mount installation is greatly simplified. Globe Rubber Works (GRW), an innovative mount manufacturer, experienced in challenging applications of special elastomers for Navy and commercial customers, heads the team of the CNF mount designer; ETC, a company with a long record of performing Navy shock and vibration engineering; and a commercial mount user, to insure that the mount research will be focused on commercial as well as Navy needs. A prototype mount will be prepared and tested to demonstrate how the concept can be used to greatly reduce the number of mounts required by the Navy.

Title:A Novel Processing Technique for the Large-Scale Production of Red Phosphorus
Abstract:Current techniques for the production of red phosphorus powders cannot produce 5m size powders while maintaining a pure surface. Two new processing techniques are suggested that are capable of processing red phosphorus into powders 5m or smaller in size. These techniques have been demonstrated with conventional metals and alloys but not with phosphorus. One important advantage of these processing techniques is their ability to apply a surface passivation layer on these powders in-situ, since 5m size or smaller phosphorus powders present a fire hazard. The passivation layers proposed here will provide a dual-benefit namely keep the powders inert during handling in ambient atmosphere while also adding to the fire retardant capabilities. The Phase I program will establish feasibility of processing by both techniques. The quality of powders produced as well as the processing costs will be utilized to narrow down the processing into one selected approach at the end of Phase I.

Title:Manufacturing Techniques for Red Phosphorus Powder
Abstract:Reducing the particle size of red phosphorus may increase its fire retardancy by an order of magnitude. The Navy requires five-micron red phosphorus. Current European production yields thirty-micron phosphorus; there is no commercial production in America. Once produced, further size reduction may cause fires or explosions due to phosphorus sensitivity. TPL will apply four established industrial processes to manufacturing red phosphorus, all having innovative potential to directly produce five-micron particles, eliminating the hazardous step of comminution. The processes include quenching, atomizing, fluidizing, and extruding. TPL will combine its experience with energetic materials and nano-sized particle production to choose the best design for further development. Design packages including PFDs, P&IDs, and SOPs will be generated for each of the four processes. Then a hazard analysis, feasibility study, and cost analysis will be performed. process with the least inherent hazards and most promise will be chosen for further development. TPL is a leading company in applying energetic materials and producing nano-sized material, offering TPL more potential than other companies for successful production of five-micron red phosphorus. TPL has demilitarized 1700 tons of pyrotechnics, selling recovered material commercially. TPL's nano-sized barium titanate is available from Aldrich, Alfa Aesar, and Cerac Specialty Powders.

Title:DURESS; A Durable, Environmentally-Compliant Non-Skid Coating System for Naval Fleet Applications
Abstract:Non-skid coating systems for various naval applications consist of a primer applied directly onto the deck substrate, a topcoat containing aggregate to generate the non-skid properties and an optional color topping. Current systems exhibit low durability, experience impact damage, are prone to delamination at every interface, and readily absorb naval and aviation chemicals on exposure, transforming the material into hazardous waste upon removal. Foster-Miller proposes to develop a "No VOC", durable, environmentally-compliant non-skid coating which will overcome the limitations of current systems as well as meet or exceed performance specifications according to MIL-PRF-24997A. Our concept begins with a reactive primer to both chemically and mechanically bond to the deck, upon which another reactive topcoat system containing conventional aggregates is applied to chemically bond itself to the primer, forming a total coating system exhibiting superior delamination resistance. Our matrix material has been selected to be less brittle, more resilient and exhibit increased chemical resistance compared to current polyamide epoxies. These factors will combine to yield a coating system with enhanced performance and durability. Incorporation of the primer system into the topcoat, generating a one-part system, will be investigated in the Phase II program.

Title:Non-Skid, Non-Flammable Coating for Navy Applications
Abstract:Naval transports and ordinance are currently coated to prevent corrosion and other destructive weathering phenomena. These coatings have a limited life-span as adhesion is compromised when they degrade on exposure to light, moisture, abrasive wind and wear. Special properties necessary for naval coatings include non-skid characteristics, corrosion and fire resistance, high mechanical strength and chemical stability. Current non-skid urethane coatings have high flammability and poor life-cycle performance. TDA Research Inc. (TDA) has developed a tough, corrosion resistant hybrid organic/inorganic urethane coating that is expected to have excellent non-skid and fire retardant characteristics. The coating can be applied to a variety of substrates, including aluminum, steel, fiberglass and wood, by existing technologies. This chemically resistant nanocomposite coating is anticipated to have excellent long-term physical properties leading to reduced maintenance costs. In Phase I, we will prepare the hybrid polymer and examine the coatings applied to several substrates. Properties will be optimized by choosing the appropriate nanocomposite and formulation. Samples will be provided to the Navy for testing. In Phase II, TDA will collaborate with a major coatings producer to prepare 100lb quantities of resin and conduct market testing. Commercial applications include walkways, ship and pool decks, a $50 million dollar market.

Title:Non-Skid Surface Coatings for Navy Fleet Applications
Abstract:Non-skid coating materials are used for treatment of aircraft carrier flight deck surfaces and numerous other fleet applications. Current non-skid products require frequent replacement, generating large amounts of hazardous materials and requiring the expenditure of scarce maintenance funds. These systems, such as the ones used on aircraft carrier flight decks, have poor resistance to chemicals and corrosion. Cracking and spallation routinely occur due to aircraft takeoffs and landings. Texas Research Institute Austin, Inc. (TRI/Austin) will develop entirely new non-skid coating systems that will have substantially improved performance when compared with available products. During Phase I, we will investigate new aggregate materials that promise to enhance coating life and non-skid performance. Starter formulations will be procured to use in the preparation of new coatings and primers. A battery of tests will be used to screen candidate formulations, and promising formulations will be modified to enhance performance. Further bench scale testing of these formulations will be conducted, and the new coatings will be compared with existing systems. Coating chemical resistance will be evaluated, and cleaners for non-skid coatings systems will be identified and tested. A comprehensive final report will be prepared, and formulations will be delivered to the Navy for evaluation.

Title:Generic Fiber Optic Link Simulator Using Lab View
Abstract:Design aids to assist engineers in the development of fiber optic communication systems using either off the shelf or custom-built components normally consist of specifications (such as EIA-626), handbooks, textbooks, spreadsheets or custom software built around a particular manufacturer's fiber optic components. A more generic simulation tool incorporating a graphical user interface is needed to allow system engineers to quickly and accurately design fiber optic systems. We propose to develop a dual-use software system based on LabView, a popular simulation and virtual instrument software package. LabView is capable of simulating all the necessary functions for designing fiber optic communication systems. The advantages of this approach are that the software is already supported by National Instruments and widely used in both industry and academic environments, it has a well-known and easy to use graphical interface, and finally the simulation tool can also be used as an analytical instrument for verifying performance of the simulated system after it has been constructed.

Title:Advanced Fiber Optic Link Simulator
Abstract:In the continually advancing information age, the needs for rapid and high-performance data communications capabilities are increasing exponentially. The capabilities of strictly electronic communications technologies cannot keep pace with these rapidly increasing demands, and optoelectronics and fiber optics technologies have stepped in to meet the challenge. Fiber optics are now heavily used in long distance telecommunications as well as high-speed data communications and are rapidly gaining market share in desktop LANs. There have been great technical advancements recently in optoelectronics manufacturing and consequently in the performance of fiber optic links which utilize the advanced optoelectronics components. However, automated computer-aided design (CAD) tools for the design of fiber optic links have not followed the same pace of development. There is a lack of reliable software for the simulation, analysis, and design of fiber optic links. The continuing advancement of fiber optics technologies requires that CAD tools for their design be developed which will accurately model all the significant performance degradations and nonlinear effects inherent in these systems to facilitate their design optimization. RSoft, Inc. proposes to develop advanced software for fiber optic link simulation and analysis which will support cost-effective design of high-performance fiber optic links.

Title:Digital Fiber-Optic Link Simulation Development
Abstract:This proposal focuses on the development of fiber-optic link simulation software with a graphical user interface (GUI) to perform link analysis as described in ANSI/TIA/EIA-626-1995. In particular, the simulations will incorporate detailed physics based models for the fiber-optic components to simulate the loss, distortion, jitter, and noise characteristics of the links. The final simulation will be able to display time-domain signals at user selected points in the link, the eye pattern, optical source power versus drive current, and the bit error ratio for the link. The uniqueness of Toyon's Research Corporation's approach is that we will rely on or experience developing analog photonic simulations and use our existing analog link analysis tool, PHLASH, as a starting point in this development. The resulting software will be referred to as PHLASH-Digital Version (PHLASH-DV) and will be a PC-Windows simulation written using C++, and utilizing an object-oriented style of programming. In addition, Toyon will modify and add to the existing PHLASH models to add a digital link analysis capability. We will optionally investigate the possibility of folding our optimization capabilities into the PHLASH-DV code to allow the optimization of selected components and their parameter values to achieve the specified system requirements.

Title:Process Design and Feasibility Study for the Automated Production of Fiber Optic Ferrules by Ceramic Injection Molding
Abstract:Demonstrate the feasibility to injection mold precise ceramic fiber optic ferrules using a high density, low pressure molding process and a rapid, fully automated, manufacturing cell. Injection molding has the potential to reduce the cost of ferrule manufacturing by molding blanks to near net shape, reducing the number of grinding operations, and to such precision that critical grinding steps are reduced or eliminated. However, the process is inherently more expensive than the process currently used to produce blanks, limiting the advantage of a near net shape. Precise process control for each individual part must be maintained during thermal operations to control minute distortions common to all ceramic product that will negate the advantage offered by a dimensionally precise blank. A high density, low pressure molding system provides low processing shrinkages and stresses for precise dimensional control. The proposed cell will produce blanks an order of magnitude faster than conventional processes at a cost similar to an extruded blank and with precise process control for each part. The process is continuous and economically dependent upon batch size, making possible the cost effective porduction of small volumes as well.

Title:Dynamic Firing Zone Imaging System
Abstract:An automated dynamic firing zone generation imaging system is needed to increase the effectiveness and utility of shipboard weapon systems. The current manual firing zone definition process is manpower intensive, complex, and cannot account for motion or changing topside configuration. These limitations greatly restrict the lethality and utility of shipboard weapons. This project proposes a dynamic firing zone 3D imaging system that runs in real-time and tracks with the weapon collecting both static and dynamic boresight scene data. The imaging data is correlated with existing reference computer CAD models, weapon configuration, and ship check information. Automated firing zones are generated and cutout definitions are made available for dynamic weapon system firing zone update. The firing zone, weapon system and ship structure are also displayed in 3D to allow engineer validation in a user-friendly and non-manpower-intensive way. The Phase I technical objective is to demonstrate the feasibility of DynaZone dynamic firing zone imaging system that accounts for motion while reducing the manpower intensity and complexity of the current firing zone generation process.

Title:Photonic Integrated Circuits for Self-Routing in Packet Switching
Abstract:A GaAs based integrated circuit is proposed as a means to implement optical network switching technology for phased array antennas (PAA) and ATM switching functions. The integrated technology offers a family of components in monolithic form and combinations of these devices can be used with an optical fiber input, to strip the header from the incoming optical signal and to use this routing information to set up a path for the optical data of the payload without O/E conversion. This technology has produced vertical cavity surface emitting lasers (* 2 mA threshold), vertical cavity resonant detectors (0.6 A/W responsivity), high performance heterostructure field effect transistors (ft > 40 GHz) and waveguide absorption modulators (35:1 contrast) all using a common fabrication sequence. This technology is realized with a single epitaxial growth upon a GaAs substrate, and uses a single set of fabrication steps to realize a monolithic integrated circuit with electronics, emission, detection and modulation capability. A essential component for the all optical switching function is the HFET waveguide directional coupler switch. Using this switch for optical routing and controlling it with HFET logic, a high speed switching network can be realized. The other essential component for the self-routing function is the HFET modulator/detector which is able to remove the header by O/E conversion and then use the resulting electronic code to set up the optical switching path. These photonic circuits can implement a complete III-V chip set for an optical switching network. With this device compatibility, it is possible to implement the header removal, the header decode logic, the switch set-up circuits and the optical switching network within the area of a single integrated circuit. For the PAA, the headers contain the phase delay data for routing optical RF signals through a True Time Delay network and with sub-micron scaled devices, this function can be performed at data rates approaching 100Gb/s. In this program the integrated circuits for all optical signal routing with optoelectronic header conversion, decode and set-up for an optical switching network system with fiber inputs and outputs will be developed.

Title:Fast All-Optical Packet Header Processing for Self-Routing Switch
Abstract:Physical Optics Corporation (POC) proposes to design and develop an all-optical packet header processing system that will perform all- optical self-routing for future optical ATM networks and optical phased array antennas. The proposed packet header processing system uses optical content addressable memory (CAM) for fast, parallel and all-optical processing, where CAM contains all the routing information. Therefore, the proposed packet switching can route high-data-rate signals in a time interval less than the packet length, so that the switch is ready to route the packet as soon as it arrives, preventing any congestion. During Phase I, POC will focus on designing CAMs for 2x2 and 4x4 switches, demonstrating through computer simulation the feasibility of the subsystem so that it can be applied in Navy phased array antennas and computer simulation. Phase II will proceed to optimization of a 16x16 prototype and initial commercialization.

Title:Corrosion Resistant Composite Launch Tube for Out Board Submarine System
Abstract:The project is dedicated to the development of a composite construction for the launch tube of an out board submarine system that would attain an extended service life of 10 years. This is a complex R&D project that includes: determination of design parameters of operational force-temperature-time conditions; selection of the appropriate structural and refractory coating materials; selection of a rational composition alternative to the existing system; development of a manufacturing process outline; analysis of strength and serviceability of the composite launch tube construction; development of an accelerated life test program, design of a special experimental set-up and of test models; environmental survey of the candidate materials. The determination of the design parameters of operational loading and of construction will be carried out by means of computer modeling of the launch's thermodynamics, the predictable evaluation of the dependence of the structural material's fatigue resistance on the force-temperature-time operational parameters and the simulation of the launch tube's behavior under loading. For this purpose, original analytical algorithms will be developed and an existing version of the MFE software will be updated, within the framework of the project.

Title:Corrosion Prevention and Control for Outboard Submarine Systems
Abstract:The Mk 77 Mod 0 Gas Generator launch tube used on SSBN submarines is currently constructed from 1026 carbon steel. The launch tube O-ring seal surfaces are exposed to sea water and are subject to corrosion resulting in an 18 month service life. A polymer composite material is required that can replace the steel and extend the service life of the launch tube to 10 years. Texas Research Institute Austin, Inc., proposes to develop a lightweight, low cost, corrosion-free polymer composite material to replace the corrosion prone steel. The composite material will meet the current launch tube design requirements including hydrostatic pressure, underwater explosive shock, shipboard vibration and ordinance testing. The composite material will be non-water soluble, and will not show significant degradation and will be able to form water tight seals over a 10 year service life. The Phase I project will determine the feasibility of replacing the metallic launch tube with a composite material and will consist of defining the design requirements, conducting a composite materials survey and evaluation, conducting a design study, fabricating subscale test articles, determining activation energies of candidate materials and preparing an accelerated life test plan for the composite launch tube.

Title:Safe, Environmentally Benign, Low Cost, Wakeless Monopropellants
Abstract:The end product of this proposal is an improved monopropellant which is safe, non toxic, water soluble, very low cost, energetic, environmentally benign and wakeless. Calculations show that a stoichiometric blend of the water soluble constituents produce a monopropellant having an energy density of 1100 Btu/# (British thermal units per pound) and an adiabatic flame temperature of 2300 F (Fahrenheit). This monopropellant is projected to be insensitive to impact up to and including the shock imposed from military rifle fire. Experimental determinations and verifications of physical properties and of stability of the monopropellant are proposed in Phase I. Drop weight impact testing will demonstrate the insensitivity of the monopropellant to mechanical shock at levels below those encountered in blasting cap tests. Also in Phase I a proprietary technique will be demonstrated which prevents any possible detonation should the monopropellant rise above a selected temperature during the most severe test of Mil-Std-2105, the cook off or bonfire test. In the Phase I Option, preliminary combustion tests are proposed in the Alternate Fuels Combustion Test Fixture. Also, scaled safety tests will be performed as precursors to the full scale Mil-Std-2105 tests scheduled in Phase II.

Title:ALUMINIZED TORPEDO PROPELLANTS
Abstract:Alex (nanosize aluminum) powder is being considered by several U. S. Navy groups as a propellant additive because it markedly increases combustion rate. Extrapolating equations for single particle combustion of aluminum shows the particle life of a 100 nanometer particle to be about 40 nanoseconds. Its small particle produces oxide that would minimize being accumulated on engine parts. Alex's rapid reaction with water also suggests its use for aluminum-sea water propulsion schemes. Alex's combustion would be enhanced by its metastable structure that provides energy in the form of a heat burst that occurs at about 400 C, causing a transformation in crystal morphology. Hydroxylamine nitrate (HAN) is a monopropellant that has been considered by the Navy as an Otto Fuel II replacement. We propose a cooperative study to support NUWC-Newport by providing samples of improved Alex compatible with stabilized HAN. We would coat Alex particles with organics that would provide increased energy over oxide passivated nano-aluminum, while shielding the aluminum from premature reaction with oxidizers such as HAN during storage. Using coated particles we would determine the feasibility of producing stable HAN-based gels. We would also develop aluminized jet fuels for potential bi-propellant systems.

Title:Embedded Intelligent Tutoring Systems
Abstract:As military budgets are reduced, it becomes even more critical to train operators efficiently and effectively. Individualized training via embedded Intelligent Tutoring Systems (ITSs) is one methodology with the potential to provide instruction that is individualized to the capabilities of the user. While there are many training environments that would benefit greatly by the implementation of an ITS, the cost of developing them tends to be prohibitive. To standardize the process of developing an ITS, and therefore, make them more accessible, Digital System Resources (DSR), Inc. proposes to provide an innovative and cost-effective Integrated Intelligent Tutoring Environment (IITE) that can be used to develop ITSs for many applications. The IITE brings together the tools required to develop ITSs in a more automated fashion, including an automated knowledge engineering tool, advanced testing techniques that develop a student model, and COTS authoring software to develop the curriculum. We will also use this same architecture to develop a performance metrics and monitoring capability in a real-time environment in order to provide accurate trainee and system performance feedback. The development of ITSs using the IITE will result in reduced development time, increased learning and retention, shorter learning cycle, increased motivation, and a precise real-time performance measurement capability.

Title:Embedded Intelligent Tutoring Systems
Abstract:An innovative Intelligent Learning Center (ILC) will be developed for application within the Tactical Control Program (TCP). The ILC will incorporate and integrate interactive courseware (ICW), simulation-based, and case-based intelligent tutoring technologies to address the unique knowledge, skill, and decision-related requirements of the TCP. The ILC software will be compatible with the TCP software and will integrate actual data from the TCP as part of the training process. This compatiblity will also facilitate ultimate embedding within the TCP and the Defense Information Infrastructure Common Operating Environment (DII COE). The ILC will: Conduct embedded, computer-aided training (i.e., no instructor required); Train concurrently with normal TCP operations; Monitor student progress and provide immediate tailored coaching; Train to a consistent performance level and mastery of defined objectives; Document training conducted and knowledge/skill mastery; Provide system-supervised practice to maintain proficiency; Adjust to changing training requirements and environments; and Provide knowledge that can be embedded as an intelligent agent. The Phase I objectives (both base effort and option) for this project will be to: 1) identify the optimal approach to developing an ILC for the TCP based on analysis of the broad range of program knowledge, skill, and cognitive learning requirements; 2) develop an ILC design based on this approach; and 3) develop a prototype ILC for a selected TCP tactical objective, such as selection of sonar or weapons settings.

Title:Tunable Vibration Absorber System
Abstract:In Phase I a system for structural hull vibration reduction using tunable vibration absorbers will be developed which can reduce the radiated noise of small underwater vehicles using minimum weight, volume and energy. This system will use minimal power for tuning control and monitoring in comparison to the use of active noise control. This is especially important for electrically powered UUVs which carry a limited energy supply. The basic concepts to be used for adaptively controlled frequency tunable resonators were demonstrated in part in an earlier program. This program will extend tunable vibration absorber capabilities to multi modal structures such as those in torpedo hulls. Practical tunable vibration absorber devices, sized for minimum volume and weight and capable of providing specified noise reduction performance will be designed and analyzed. We will evaluate and develop additions to current tuning strategies that assure that the absorber is tuned only to frequencies related to modes which radiate well. These will range from simple lookup tables based on reciprocity radiation efficiency tests, to onboard sensors including accelerometers and hull mounted acoustic intensity probes. Associated signal processing methods capable of determining the hull mode shapes and possibly their radiation efficiency will be developed as needed. Ultimately the use of towed arrays will be available for determining real time radiated noise. The benefits of the adaptive tunable absorber system to be developed will be the capability to reduce low frequency range vibration and noise with minimum weight, small, low average power consumption devices. These devices will provide much better performance per unit weight for reducing tonal vibration than passive broadband treatments usually applied over extended areas. When combined with broad band treatments, total noise control system treatment weight can be reduced by tailoring the design of the broad band treatment to absorb the higher frequency vibration while using the tuned absorber to reduce low frequency noise. These devices will be used in applications which are sensitive to noise weight and power requirements including torpedos UUVs and advanced marine vehicles, amphibious and automotive vehicles, and manned and unmanned aircraft, particularly when variable speed operation is involved.

Title:Large-Scale Configurable Gripper for Ordnance Handling Robot
Abstract:Initiatives undertaken by the U.S. Navy will dramatically change the nature of large-caliber shipboard gun systems deployed in the next decade for naval surface fire support. In addition to significant advances in ammunition, such as the development of course-correcting rocket-assisted shells and precision terminal guidance systems, basic gun and magazine designs are undergoing fundamental changes. Large-scale, high-speed robotic manipulators mounted within compact magazines will be employed to perform automatic handling and loading of 5-inch and 155mm shells and propellant charges so as to minimize gun manning requirements, maximize ordnance stowage density and achieve the highest rates of sustained fire. No adequate gripper presently exists for such large-scale manipulator systems. The program outlined herein addresses that problem, focusing on the development of a highly flexible, configurable gripper with the dexterity, load capacity and features required to maximize the potential of automated ordnance handling robots, as well as large-scale manipulators designed for similar kinds of precision material-handling applications in industry. In Phase I, the feasibility of the design concept and specifications will be established. In Phase II, a prototype will be engineered, manufactured and tested. In Phase III, production versions of the device will be implemented for Navy and industrial applications.

Abstract:The Orbital Research Unified Control Solution will provide an efficient, flexible modular distributed control system for automated heavy payload handling systems. Part of the efficiency and flexibility of the Orbital Research Unified Control Soloution is provided by the Orbital Research Intelegent Control Algorithm (ORICA). ORICA is a proven adaptive predictive controller that uses a continuously re-identified input-output model to make a prediction about system outputs (eg. robot position) several time steps in the future, and computes a control action that will drive the robot to follow a specified trajectory. The Orbital Research Unified Control Soloution also benefits from the flexibility provided by a modular control system. This program will evaluate the ability of the Orbital Research Unified Control Solution to control a model of an automated gun magazine through all phases of operation, including the grabbing and placing of shells. The Phase I program is focused on evaluating the ability of the distributed Orbotal Research Unified Control Solution to provide a complete control solution for shipboard payload handling systems, such as an automated gun magazine.

Title:Rugged, Portable Ground Station for NSFS Targeting
Abstract:Under this project and with a follow-on Phase II, Accurate Automation will build a hand-held device for Forward Air Supprt--Marine (FASM). This device, the Hand-held Terminal Targeting/Control System (HTTS) will enabe a Marine forward observer to perform terminal control of a ship-launched missile (e.g., ERGM). It will also support two-way development of SA; the forward observer will be able to send local observations of friend and foe activities back to a central command point, and receive relevant aspects of the overall tactical picture. HTTS will contain communications up and down links (preferably using spread spectrum), a GPS receiver, batteries, and a graphical user interface (GUI), along with computational capabilities. During Phase I, we will work with members of the user community to identify requirements and design system architecture, develop communications protocols for describing SA, and construct and demonstrate a workstation emulaton of HTTS (with emulations of external communications). In the Phase I Option, we will transition to a real hardware device that can be a prototype for the final HTTS physical configuration. We will port the capabilities demonstrated in Phase I to the new environment, and demonstrate the capabiities within the new configuration.

Abstract:The purpose of this Phase I effort is to lay the foundation for development of a man-portable Battlefield Weapons and Data Management System. This device will man-portable Battlefield Weapons and Data Management System. This device will effectively interact with command elements, by helping them coordinate with other operatives, and by facilitating their delivery of fire to enemy targets. The proposed work focuses on the basic research and experimentation required to build a prototype device. During Phase I, we will construct a laboratory version that boasts a reasonable subset of the functionality ultimately expected of the final product. We will then use this prototype as a platform for software development, for the evolution of system specifications, and for the evaluation of peripheral components that other companies will provide. The results of this effort will enable us to demonstrate the viability of our technical approach. In its solicitation, the Navy states that it requires technologies to improve the effectiveness of soldiers operating under remotely supported, forward battlefield conditions. The proposed Phase I effort will demonstrate a prototype system that meets this need.

Title:Rugged, Portable Ground Station for NSFS Targeting
Abstract:Scientific Research Corporation (SRC) proposes to design and develop a Portable Ground Station that is easily carried by forward-deployed marines for use in targeting and surveillance. The Portable Ground Station will be capable of controlling and monitoring weapons and surveillance assets (UAVs) launched from ships positioned over the horizon and to designate targets to those ships and their weapons. Communications with the UAV(s) will be through a high-speed wireless data link. The wireless link will be LPI/LPD via the use of spread spectrum techniques. In addition, the Portable Ground Station shall be capable of receiving high quality compressed video using Wavelet compression techniques from the UAV(s). Thus, company or possibly smaller-size maneuver units can obtain tactical situational awareness data or neutralize specific objectives which can not be readily achieved through conventional call-fire methods.

Title:Very Low Cost, High Performance Fire Support Munition
Abstract:The current performance requirements for Naval Surface Fire Support place performance demands on the projectile far beyond what the current projectile/gun combination, or any evolutionary improvements thereto, can provide. A revolutionary approach is required. PMS-429 has taken a bold step in developing the ERGM round. It meets the formal range, accuracy and flyout time requirements nicely. The estimated cost, however, is larger than desired. In this proposal, the JDI Team has taken a different approach, called HYPA (High Performance Affordable) Munitions. We have deliberately removed the major high cost components of the designs which incorporate GPS/IMU guidance for accuracy and lifting surfaces for range. We then strive to get the best performance we can at a very low cost through a combination of clever design approaches and newly available technologies. We believe that we can achieve ranges similar to those of ERGM and other guiding and lifting designs, with a cost on the order of a factor of 5-10 less, a flyout time much faster, and an accuracy on the order of 100 meters. The objectives of Phase I are to conduct a concept formulation study, assess the commercial potential of HYPA technologies and concepts, and develop a long range demonstration plan to be implemented in any follow-on phase.

Title:NAVARM Naval Range Extender for Army Artillery Shells
Abstract:This is a proposal for the design, fabrication and test of a 155mm munition which uses aerodynamic lift to greatly extend its range. Previously flight-tested BLAM (Ballistic Launched Adaptive Munition) technology will be used to provide solid state, smart material. aerodynamic control surfaces with bandwidths of several hundreds hertz. The required munition control authority is greatly reduced because attitude errors are corrected before they become large. The solid state BLAM actuators are very light, low power, inexpensive, and reliable A 155mm BLAM will be fabricated and wind tunnel tested in Phase I. The main goal of the Phase I effort is to develop a BLAM compatible guidance system. A broad range of guidance concepts will be considered including : (1) a simple replacement of movable canards on the despun portion of the competent munition ATD; (2) a munition with reduced spin rate that does not require despinning the guidance package or any canards; (3) an RF beam rider munition requiring no despinning, canards, or INS/GPS package. The Phase II effort will fabricate and flight test a 155 mm, guided BLAM munition. BLAM technology has a broad range of applications using a broad range of guidance systems from sniper rifles to BMD.

Title:Small, Rugged Internal Combustion Engine
Abstract:The successful development of this small diameter diesel engine enables a new family of unmanned aircraft. The proposal is based on work at a world leading engine manufacturer and has a patent pending. The technology has been made available to ColTec through a license agreement. University research is being pursued. The package is 5.0 inches in diameter, 12.0 inches long and is expected to produce up to 10 horsepower at 10,000 rpm and to weigh 9 lbs. Two opposed rotors form four pumping chambers. A robust cam/roller system creates intake, compression, expansion and exhaust events (4 cycle) with each revolution. A central shaft provides power take off at either end. The unit is completely balanced. Gas flow is managed by rotor edges passing ports, so no poppet valves are required. Powder-metal and die-cast technologies are extensively specified to reduce cost and weight. Compresion ignition assures high thermal efficiency. Electronic control is integral. Dual fuel injectors increase reliability and fuel efficiency. Large area contact surfaces throughout the design, along with a novel energy absorption canister, deal with the 9000g setback forces.

Abstract:A small twin cylinder 4-cycle engine will be developed to propel a gun launched UAV. The technology exists to start and run this engine on relatively safe jet fuels at high efficiency and relatively low noise and thermal signature. Fuel consumption will be half that of a comparable 2-cycle. Relatively conservative ratings compared to automotive practice suggests long life and reliability that will be more important in other continuous duty and reusable military applications such as generator sets, robot propulsion and portable tools.

Title:Sonex Combustion System (SCS) Small, Rugged Internal Combustion Engine Operating on Heavy Fuels
Abstract:Sonex Research, Inc. proposes to develop a small (5 lb.), rugged (gun- launchable), low-cost, spark-ignited (SI) internal combustion engine that runs on a shipboard-safe heavy fuel for application to aircraft propulsion and electric power generation. The design will use an innovative extension of the Sonex Combustion System (SCS). SCS itself is now being applied to convert gasoline fueled engines to use heavy fuels in small Unmanned Aerial Vehicles (UAV's) such as EXDRONE and is undergoing UAV testing at the U.S. Naval Research Laboratory (NRL), the USMC Systems Command in Quantico, and the U.S. Naval Air Warfare Center, Patuxent River. Commercial SI gasoline engines will be identified and their SCS conversion potential assessed. The SCS NRL design will be scaled to the engine most suitable for this application. Under subcontract, Science Applications International Corporation (SAIC) of McLean, VA will help design modifications to the engine necessary to meet the 9000g setback acceleration and other SBIR transition interface requirements. The contract deliverable will be a Final Report detailing the project objectives, work performed, results obtained, including testing on a prototype engine, and estimates of technical feasibility.

Title:Small, Rugged Internal Combustion Engine
Abstract:The Department of Defense has a growing interest in unmanned aerial vehicles (UAVs) to provide over-the-horizon surveillance, detection, classification and destruction of time-critical surface targets. Forward Area Support Munition (FASM), a Navy ATD program approved for FY99 start, is a 5-inch gun-launched projectile that transforms into a propeller propelled UAV. A future engine for the system must sustain 9000 g gun launch, generate 4 Bhp, integrate into a 5-inch diameter-18-inch long cavity, and reliably start and function using a heavy low vulnerability fuel such as JP-5. To meet these requirements, Veritay proposes a compact uniquely configured 2-stroke cycle-2 cylinder cluster engine concept that exhibits inherent acceleration hardening characteristics and many other beneficial features. The proposed Phase I effort includes conceptual engine design to meet system requirements, experimental demonstration of a heavy fuel operating concept using a modified conventional engine, and analysis to show the ability of the engine design to survive a high-g gun launch. Detailed engine and control component design will occur during the Phase I optional program to permit fabrication and test early in Phase II.

Title:A Multi-Use Manufacturing Manipulator (MUMM) Based on the EMMA Robotic Arm
Abstract:GreyPilgrim LLC has patented and developed a long-reach manipulator that combines modular components in a reconfigurable, flexible, lightweight design suitable for a wide variety of commercial and government applications. We have demonstrated 8, 15, and 33 implementations of the modular EMMA robotic arm technology under DOE Hanford contracts for use in retrieving nuclear waste from deteriorating underground storage tanks. The arm is also being developed with Boeing for aerospace manufacturing processes such as cleaning, depainting, and inspection of aircraft. Much of these R&D efforts have taken place under the auspices of a CRADA between GreyPilgrim LLC and the National Institute of Standards and Technology (NIST), where an open-architecture control system is being incorporated into the EMMA controller. The proposed multi-use manufacturing manipulator (MUMM) is similar in many respects to versions of EMMA already demonstrated. GreyPilgrim is therefore able to offer substantially greater progress than is normally possible with a Phase I SBIR contract. Proposed Phase I research will focus upon system modularity, portability, and flexibility requirements, deployment scenarios, and arm/tool integration. In Phase II a working prototype will be built and tested.

Title:Context Dependent Prognostics and Health Assessment: A New PAradigm for Condition - Based Maitenance
Abstract:In today's military environment ships, systems, and equipment are being asked to perform at levels not thought possible a decade ago. The intent is to improve process operations and equipment reliability, availability, and maintainability without costly upgrades. Of course, these gains must be achieved without impacting combat readiness. Downsizing is also taking its toll on operations. Loss of personnel, particularly those who represent the corporate history, is depleting the Navy of its valuable experiential base which has been so heavily relied on in the past. These realizations are causing the Navy to rethink its condition-based maintenance policies, moving them away from reacting to equipment problems to taking a proactive approach to anticipate needs based on mission requirements. This SBIR will develop a new approach to condition-based maintanance-Context Dependent Prognostics and Health Assessment. This advanced diagnostics capability will be developed around a context dependent model that provides a capability to anticipate incipient system/element failures and determine machine performance over a protracted period of time. This prognostic capability will link mission requirements to an economic performance model. In this context, a system may provide 100% operability with less than 100% functionality. This new paradigm will be integrated into the Navy enterprise system to facilitate optimal logistic supply and support.

Title:Condition Based Maintenance Using Neural Networks
Abstract:In this proposal, Intelligent Automation Inc. (IAI) proposes an innovative new method of engine degradation monitoring, fault detection, and diagnostics, which is robust to sensor noise and is efficient in training and learning. This innovation will also allow us to detect new fault conditions that have not occurred before. This may include sensor failures and hence, the capability of validity self-checks. We propose to use two neural networks: Principal Component Analysis (PCA) and Fuzzy CMAC. PCA is a powerful technique for extracting the features inside the input signals. We have seen that PCA can reduce the signal dimension from 800 to 5 in several applications. A major advantage of PCA is that supervised learning is unnecessary. It can also be implemented in low-cost hardware. The Fuzzy CMAC (Cerebellar Model Arithmetic Computer) inherits preferred features of arbitrary function approximation, fast learning, and parallel processing from the original CMAC neural network, and the capability of acquiring and incorporating human knowledge into a system and the capabilities of acquiring and incorporating human knowledge into a system and processing information from the fuzzy inference rules of fuzzy logic. Our learning rates are at least an order of magnitude faster than conventional neural nets. The Universal Approximation Theorem that we have formally proven shows that any function can be learned to any degree of accuracy with enough learning cycles. The proposed method is relevant to the subtopic because our innovation can provide an early warning before the system actually fails. The purpose is to increase time between overhaul and safety.

Title:Machine Health Prediction for Condition-Based Maintenance
Abstract:The failure of machine components is expected but difficult to predict. The worst-case maintenance procedures are very expensive, as all parts of a given type must be replaced after a fixed number of hours, regardless of the fatigue and wear that they have experienced. A less restrictive high-fatigue schedule reduces costs but may result in a larger number of catastrophic failures. By analyzing the vibrational characteristics and performance parameters of an operating machine, one can determine the extent of degradation due to fatigue without the necessity of dismantling the engine and performing a detailed inspection of its components. The conditionbased maintenance will result in large cost savings by extending the useful life of mechanical components, reducing unnecessary maintenance, and safeguarding against premature failure of components. ORINCON proposes to develop an automated health monitoring system to predict the development of mechanical faults in an operating turbine engine and to provide suggestions for the engine maintenance schedule, based on the predicted failure mode, The system will be implemented as a combination of advanced signal processing and neural network expert systems. A general framework for machine health monitoring and prognosis will be developed and applied in Phase 11 to a ship system.

Title:COTS Approach to Information Security
Abstract:The commercial world has tended to focus on the performance of computer systems, and not always on their abilities to control information access. Many of the products and systems being developed today have wider and easier access to their data as their main goal. The precepts behind the World-Wide Web, Open Systems Architecture, and the Free Software Foundation are based on the desire to provide free, easy access to the information they control. It is not surprising, then, to find that these computer systems and architectures have real problems when it comes to security. As a result of the demand for security solutions in the commercial world, commercial solutions have become an a viable alternative for todays military systems. This propsed effort will utilize submarine combat system experts along with commercial security solutions to derive a solid solution for security requirements.

Title:The LAST Sensor: Elastomeric Large Strain Measurement Gage
Abstract:This Phase I SBIR effort investigates a novel large strain sensor concept constructed using all elastomeric materials for measuring large strains on surface of elastomers. An experimental investigation in formulation of a resistive elastomer is proposed. Concurrently, a strain field model is developed to match and guide the material selection of the large strain sensor. A sensor model is developed to predict the sensor performance and its sensitivity to the operating environment. Using these results, a prototype LAST (LArge STrain) sensor is designed, batch-fabricated, and integrated including a portable PC based data acquisition system. Each sensor is tested and characterized developing its own response curve. The LAST sensor is planned to be field tested at the Navy labs in demonstrating the concept feasibility.

Title:Fiber Optic Strain Sensors in Elastomers for Large Strain Measurements
Abstract:Physical Optics Corporation (POC) proposes to develop a novel compact submersible fiber optic strain sensor. The sensor will be suitable for operation in seawater, and capable of accurate measurements of strain or displacement to a maximum deformation of 150% strain. POC expects this sensor will find wide acceptance in the rubber and elastomer industry, where "high-tech" elastomers are receiving considerable attention. Also, the high-deformation strain sensor will be of critical interest to the Navy for programs such as the Elastometric Torpedo Launcher system, The sensor will be easily integrated into such systems for real-time monitoring of the elastomer parts during normal operations. Specifically, sensor combines two technologies: fiber Bragg grating strain sensors and elastomer fiber optics. In Phase I, POC proposes to demonstrate the feasibility of the elastomer fiber optic strain sensor.

Title:A Photoelastic Technique For Measuring Large Strains On The Surface Of Submerged Elastomers
Abstract:The technology to accumulate and store significant levels of strain energy in an elastomeric material has been widely demonstrated through inflation of various shapes using both air and water pressure. Familiar examples include automobile tires, toy balloons, and some types of recreational and scientific balloon like devices. In most cases, however, these devices are not specifically designed for energy storage through deformation of the elastomeric material. The fact that energy is stored within the elastomer is an unavoidable consequence of the design. Also, other than toy balloons, these objects typically do not undergo significantly large mechanical strain during normal operation. Another class of elastomeric parts includes diaphragms in fluid pumps. These parts often undergo large strains, but are not typically designed to store energy as a primary objective. A third class of parts includes certain fluid pump diaphragms currently under consideration for future applications in ocean engineering. These parts are designed for energy storage specifically through accumulation of large mechanical strains. Optimal design of these parts requires ability to numerically predict and experimentally measure the distribution of mechanical strain on the surface of the part. The measurement must be done in-situ while submerged in water. Proposed herein is investigation and determination of the feasibility of a process to measure these large strains in-situ using photoelastic coatings. A program is proposed which includes research, technology shortfall identification, technology solution exploration, concept design for the process, and performance of a riskmitigation scale model experiment to demonstrate feasibility. Accurate measurement of surface strains on inflated elastomers is critical to future development of efficient, long lasting diaphragms for large fluid pumps. The measurement technology is needed for product design validation, proof testing, and in-situ operational condition monitoring and assessment. The use of elastomeric materials is widespread in many industries, both in air and in water. The technique proposed herein is expected to be widely applicable in these industries.

Title:Combat System Testing & System Integrity Tools
Abstract:With COTS based systems requiring technology upgrades during development and after system delivery, T&I will become a series of perpetual integration periods. T&I for the C3I will occur at each of the development facilities, the COATS, and the platform. T&I at the COATS and the platform present the biggest challenge due to the complexity of the respective T&I environments. The individual subsystem developers will perform testing as early as possible including using the WAIF to conduct early S/CC/A subsystem interface testing. Great care has been taken to establish a sound process for Integration and Test of the submarine system. When considering the complexity of NSSN and the number of new COTS components that will used, there will be significant opportunity for innovative (cost saving) processes to be established. After the SDCT period, problems will undoubtedly be uncovered during the T&I periods at the COATS and on the platform that will require find, fix and retest (FFR) efforts. These FFR periods represent biggest challenge for the C3I system in that the amount of retesting (i.e., regression testing) required has a significant impact on the overall T&I period. This SBIR's objective is to help reduce and automate the test process for large, complex military systems.

Title:Plasma Antenna
Abstract:The development of stealthy, dynamically reconfigurable antennas that can detect radar signals between 1-40 GHz using plasmas is proposed. The proposed antennas size is small enough to fit in a periscope barrel, with diameter 7 inches and height 3 inches. The reconfigurable antenna is based on capillary plasma discharges. Such discharges require very little energy, and create, highly conducting plasmas with the shape of capillary. Various antenna configurations can be created by synthesizing capillaries, which can receive as well as transmit signals. During the first phase of the proposal trade off studies will be performed to select the optimum design of a plasma antenna configuration, and test a simple dipole configuration of the capillary plasma antenna.

Title:Augmenting CORBA with High Assurance Data Integrity Mechanisms
Abstract:The ultimate goal of the proposed R&D is to design, develop and validate innovative CORBA-based software security services and compatible hardware architectures which provide high assurance for multi-level secure (MLS) network applications. The proposed approach is innovative in that it is based on the emerging OMG Security Services Specification (SSS) plus a proprietary technique for maintaining the integrity of stored data items. This latter feature is not addressed by the CORBA Security Services Specification and is critical for the trusted implementation of automated release mechanisms (guards) which regulate the flow of data between different MLS protection domains. The Phase I objectives include an assessment of CORBA architectural implications with respect to security evaluation criteria and certification requirements, and the development of an implementation approach for a high assurance data integrity mechanism. This data integrity mechanism is based on public key encryption methods and will prevent unauthorized information flows in conjunction with other security enforcement mechanisms. A proof-of-concept prototype will be developed to demonstrate the feasibility of our data integrity mechanism and explore the limits of scalability for a CORBA-based MLS network architecture to ensure our approach will be usable in realistic operational settings.

Abstract:This SBIR focuses on researching and selecting a new, better, and cheaper digital processing architecture for inclusion within an existing submarine tactical system. Although VME has already saved the government millions of dollars in development costs compared to the cost of producing full-mil, specialized hardware and software, there is yet another step in the cost reduction process. The commercial market is today producing highly capable, low-cost system solutions which, now that the COTS concept has been proven out, can perform many of the tasks which VME is doing today, and can perform those tasks cheaper. This development effort should start as early as possible, both to leverage savings in systems not yet developed but planned, and to assess the market's ability to support system development in the near term.

Title:Low Cost Sonobuoy Technology Applied to Towed Arrays
Abstract:The objective of this program is to develop a low cost hydrophone for use in towed line arrays. To this objective, Phase I will identify and develop hydrophone array assemblies using cost-effective hydrophone designs. This will be accomplished through the use of sonobuoy technology as related to design and manufacturability. During Phase I the specification requirements for the array will be determined and a new hydrophone element design will be developed. The hydrophone elements will be designed into an subarray. This subarray will be of a form factor that direct replacement of current subarrays may be accomplished. This program will identify the hydrophone design, the methodology of manufacturing for the hydrophone element and the subarray, and an assessment of the required manufacturing labor. In addition, the cost of the proposed subarray design will be determined as purchased in quantities of 4000. Phase I will also demonstrate, that the proposed hydrophone element meets the design specification. It will also show how the hydrophone element is integrated into the subarray. It will show how the hydrophone could be developed into a family of hydrophones that apply to a wide range of subarrays for towed array applications.

Title:Sonar Performance Enhancement in the Littoral Environment
Abstract:A significant amount of effort has been applied to the extremely complex littoral environment, particularly in the area of acoustics. The Navy's increasing requirements to operate in shallow water necessitates examination of the Navy's models for prediction of shallow water phenomena. Ambient noise in shallow water is not well understood or well modeled. Surf noise is a major contributor to ambient noise in shallow water and offshore. Surf noise has been observed at distances well over 10 km seaward of the surf zone by operational Navy sonars (Stewart, 1994) and by a limited number of measurement exercises (O.B. Wilson, et al., 1985, Fabre and J.H. Wilson, 1995). Surf noise is a shallow water phenomena that is only recently becoming understood. It has been shown that surf noise is broadband noise that propagates from unique surf zones several kilometers to sea and can be dominate measured broadband ambient noise fields (Stewart, et al., 1994). To ensure success in today's shallow water missions, the Navy needs a clear understanding of the propagation characteristics and noise fields. A surf noise model (Wilson, et al., 1997; Fabre and Wilson, 1997) developed by Neptune Sciences, Inc. (NSI) and the Naval Postgraduate school (NPS)is based on an inverse technique in which the surf noise source level density (SLD) in the surf zone is deduced from ambient noise measurements taken many kilometers seaward of the surf zone. The critical factor in applying this inverse technique is to be able to model the transmission loss (TL) accurately from points along the surf zone to the surf noise measurement location seaward. Ambient noise due to shipping and local wind/wave-breaking are estimated and subtracted from the total noise measured. The reason that the site dependent TL modeling is so critical is that, if done accurately, the SLDs estimated for surf should be site independent. The SLD should only depend on frequency, wave height and type, and surf zone width and not on the propagation conditions from the surf zone, seaward. Thus, once derived, the SLD can be used to estimate surf noise in other areas where surf noise measurements do not exist. That is, the surf noise model (the SLD and TL model with inputs) can be used to accurately estimate surf noise at any location in the world. These concepts will be illustrated with past surf noise data analyses performed by NSI/NPS (Wilson et al., 1997; Fabre and Wilson, 1997).

Title:Novel, adaptive, scanning laser vibrometer for measurements on rotating propellers in water
Abstract:This Small Business Innovation Research Phase I project will investigate a novel alternative to the laser Doppler vibrometer for measurements on rotating propellors in water. Specifically, we will investigate a vibrometer based on photo-emf detection, in conjunction with conventional rotational tracking. The vibrometer incorporates a reference-beam interferometer to provide optical signals to the photo-emf detector. We believe that this type of vibrometer is significantly less susceptible to undesirable signals and added noise that compromise the performance of conventional Doppler vibrometers. We will describe preliminary experiments which support this point of view. During the program we will characterize and optimize our interferometer, leading to a direct side-by-side comparison with a Doppler instrument. At the conclusion of the Phase I effort we plan to demonstrate the feasibility and advantages of our approach, which should result in a robust, low-cost scanning device which can interrogate diffuse surfaces with minimum impact from the beam rotation process.

Title:Optimized Scanning Laser Doppler Vibrational Measurements on Rotating Propellers in Water
Abstract:Systems and Processes Engineering Corporation (SPEC) proposes to develop a straightforward methodology for the setup and operation of a rotating beam laser vibrometer to map and measure the vibrations of a rotating naval propeller in water. SPEC will develop a measurement system which integrates a laser vibrometer, a SPEC developed image derotator system, control software and straightforward alignment methodology. The compact image derotator system will incorporate remotely controlled piezoelectric alignment elements and integrated computer control for rotation and phase control. This component will provide a stationary image of the rotating object and probe beam and will provide visual feedback for the alignment of the probe beam with the rotational axis of the propeller. Various system configurations will be considered and the relative merits evaluated. The final delivered system will be a rotating beam laser vibrometer system with associated documentation for setup and operation

Title:Combat Systems COTS System Administration
Abstract:Integrated Electronic Technical Manuals (IETM) are used by maintenance and operating personnel to obtain technical information and trouble-shooting procedures for ship's equipment. For the New Attack Submarine (NSSN) Non-Propulsion Electronic Systems (NPES), the current plan is for the operator to bring up an IETM viewer, of which there may be several types, and manually index to the appropriate section of the IETM. We propose to design and implement an Automated Performance Support System Tool (APSST) to integrate this capability directly into the NPES System Management function. The APSST will start the IETM viewer and automatically index to the appropriate section of the IETM, thereby providing an intelligent, interactive system administration tool for systems diagnostics. The APSST will also bring up viewers for Interactive Course Ware (ICW) where this is appropriate.

Title:Next Generation Combat System Display
Abstract:DSR proposes three new concepts to improve performance and reduce workload for all SSN Combat Systems operators. 1) The automated generation of geographic situation (GEOSIT)-Plan View displays with icons and linked vectors representing ownship and contacts being held. 2) Classification confirmation and contact monitoring with SmartAudio providing post beamformer audio processing gain and high signal to noise (SNR) spatial presentations for Passive Broadband and Passive Narrowband contacts. Relegation of gram reviews using colorized grams to backup analyses. 3) 3D Navigation displays with bathymetric data and mine avoidance cylinders. These displays can be isographic renderings or true stereographic presentations, separate left and right eye "Viewmaster"-like images to significantly enhance navigation for obstacle avoidance in shallow water by enabling a true 3D view with depth perception. These improvements are required because new Submarine Combat Systems are providing more information in gram format for operator review. Future littoral and battlegroup operations will require more precise navigation and will place more difficult time constraints on operators for analysis and review. Fortunately, the video game driven commercial market is providing the pull for new multimedia technology that can be exploited to reduce operator workload.

Title:Unified HP/RT Development to Deployment Middleware Platform
Abstract:A significant problem for modern combat control system implementations is the incompatible development and deployment environments. These applications have specific performance requirements that until recently were only accurately obtained on the target installation system. However, for various logistic and economic reasons, the platforms utilized for advanced applications have typically been incompatible with the target combat system. In recent years, technological advances in middleware technology has enabled a significant reduction in the incompatibilities between these two environments. Increasingly, high-performance hard real-time application development efforts can be expected to employ modern software development methodologies for the implementation of their operational capabilities. This is demanded by the shift to commercial-off-the-shelf (COTS) hardware and software solutions to meet stringent low-cost objectives for new Navy procurements. This SBIR proposes a Unified HP/RT Middleware Platform as a high performance, hard real-time, distributed object-based, economically efficient approach to the integration of advanced development and COTS applications.

Title:Migration of Advanced Development and COTS
Abstract:This effort will provide a Tactical Operating Environment to support migration of advanced development and COTS applications by implementation of a common Network Environment (CNE). The key innovations are using Interface Definition Language (IDL), Internet Inter-Object Protocal (IIOP), Common Object Request Broker Architecture (CORBA) and a Java viewer. These innovations, when implemented, will provide a middleware environment in which native tactical, advanced development, and COTS applications will continue to execute unchanged, but data and products from these applications can be simultaneously viewed in a coherent space using Java viewer. The primary factors for coherency in the viewer are envisioned to be time, space, scale and projection.

Title:Development of Aluminum Nitride Infrared Window by HVPE
Abstract:TDI proposes to develop aluminium nitride infrared window material using hydride vapor phase epitaxy (HVPE) of AlN. The HVPE technique is a well-established, relatively cheap method to grow thick layers of GaN on sapphire and silicon carbide substrates. This epitaxial method provides high growth rate sufficient to obtain quasi bulk material. Our recent experiments show that high quality, thick AlN epitaxial layers can be grown by HVPE. AlN free-standing platelets have been obtained. Preliminary experiments indicate that grown AlN is transparent in the wavelength region from 2 to 6 microns. These results open the opportunity to develop large area AlN high quality infrared window material. The goal of the Phase I is to prove the concept and demonstrate free-standing 1 mm thick AlN platelets with a lateral size at least 15x15 sq.mm. We will measure physical properties of grown AlN, including optical absorption in the wavelength region from 1 to 10 microns. Test samples will be delivered. In the Phase II, we will focus on the development of multi-wafer HVPE growth process for AlN deposition. We plan to grow and characterise 25 - 50 mm diameter, 2.5 mm thick AlN disks having high crystal quality and absorption coefficient < 0.1 per centimetres at 4 microns.
