| Title: | Extending the Dynamic Flowgraph Methodology (DFM) for Automated FMECA and Diagnostic/Prognostic Requirements Optimization Analysis |
| Abstract: | This innovation proposes the development of a technical tool for automated FMECA and diagnostic/prognostic requirement optimization analysis of system designs and implementations. This tool will fill a void that is currently not addressed by any analytical techniques, where the FMECA and design optimization processes are closely integrated with the design/development cycle. FMECA results are fed into an automated optimization analysis. A graphical model of the system is developed and analyzed by means of a formal logic analysis technique called the Dynamic Flowgraph Methodology, which is capable of identifying a desirable mixture of diagnostic/prognostic capability to mitigate the effects of the critical failure modes found in the FMECAs. This innovation has high technical value and commercialization potential, as there is a widespread requirement and use of FMECA in the government and in the commercial sector. |

| Title: | Advanced Failure Modes and Effect Criticality Analysis (FMECA) Models that Accurately and Quickly Identify Optimum Levels of Prognostic Requirements |
| Abstract: | To develop and demonstrate an accurate and easy to use advanced FMECA modeling capability that would allow timely optimization of various aircraft subsystems. There is a need to improve and streamline the requirements definition process for diagnostic, prognostic, and health management. This should be possible in early conceptual and design stages. An advanced FMECA model can be used to identify the optimum mixture of diagnostic, prognostic, and health management capabilities. This capability would be used to aid in making the necessary trade-offs in order to define the optimum final system design. This analytical tool will be used in the development of any complex engineering system. In particular, commercial manufacturers of fixed-wing or rotor wing craft aircraft could utilize the tool to specify diagnostic, prognostic, and health management capabilities in their design. Such a tool may also be applied in non-military (offshore, civilian aircraft, marine and mining) fields. In addition it will promote application of failure analysis in other industries which currently are unable to do it due to lack of know how and financial resources. |

| Title: | Advanced FMECA to Identify Optimum Diagnostic and Prognostics Requirements |
| Abstract: | Impact Technologies in cooperation with the Applied Research Laboratory (ARL) at Penn State University propose the development, implementation and validation of an advanced FMECA modeling capability that can provide optimized health monitoring system requirements for existing or new acquisition Naval aircraft systems. The integrated FMECA modeling approach and specific optimization algorithms utilize a combination of conventional FMECA results, health management system strategies, maintenance/inspection scenarios, and metrics from various diagnostic/prognostic technologies to optimize the sensory, diagnostic, and prognostic system needs in terms of mitigating the FMECA identified failure modes. The proposed program will utilize advanced system optimization and evolutionary algorithms such as genetic algorithms to seek out the best health management system configurations and capabilities based on a corresponding set of "cost" or "fitness" functions that accurately represent the key system variables. Key variables such as reliability, complexity, cost, risk and sensitivity of the sensor systems, diagnostic/prognostic technologies and maintenance/inspection strategies will be addressed by this function. Hence, the effort shall be capable of identifying and ranking candidate aircraft subsystem health management system requirements, through an exhaustive search of a potentially enormous solution space considering the multitude of potential sensor, diagnostic, prognostic and maintenance technologies. Finally, this hierarchical FMECA modeling capability and health management system optimization process will be developed in an open systems architecture and demonstrated on a Naval aircraft subsystem. The advanced FMECA integrated model will be capable optimizing the health monitoring system requirements so that critical Naval system failures and high cost operation can be avoided. Costly inspection routines and premature component replacements can also be avoided. Substantial safety and cost benefits are projected if the optimal application of LRU diagnostic and prognostic techniques is realized, and it could thus provide the potential to make the correct life cycle choices during the acquisition process. Commercial applications for the FMECA modeling approach can be realized on any machinery health monitoring application in the electrical generation industries, chemical processing industries, commercial aviation as well as gas transmission and oil industries. |

| Title: | Thin and Effective Erosion Resistant Coating for Compressor Impellers |
| Abstract: | Blades, vanes, and impellers in gas turbine compressors operate in dusty environments and are prone to degradation by solid particle erosion. Erosion of the impeller blades can lead to potentially catastrophic compressor failure. We propose a thin ceramic-metal composite (cermet) coating based on a sol-gel process that is designed to combat erosion effectively. The proposed coating process is simple, inexpensive, and does not use materials that are hazardous to the environment. The coating consists of metallic particles bound together, and to the substrate, via a ceramic matrix. The ductile phase provides erosion protection at higher impingement angles and the ceramic phase provides protection at lower impingement angles. By varying the type and concentration of powders in the sol, coatings with the desired erosion properties can be prepared. The thinness and smoothness of the coatings ensures that the fatigue properties are not undermined by the coating. During Phase I, erosion and high cycle fatigue resistance of the proposed coating will be evaluated on Ti-6Al-4V at ambient temperature. Phase II studies will include erosion and fatigue evaluation of the coatings in various simulated service conditions and tests on actual turbine engine components. The most promising coatings will be patented and licensed as protected technology for commercial use in Phase III. Helicopters, vertical/short take-off and landing aircraft, fighter jets, airlines and power plant turbine engines will benefit from the effective and economical protection afforded by the proposed coatings. Moving mechanical assemblies (MMAs) used in spacecraft and diesel engines will equally benefit from the hard and tough coatings developed in this proposal. Some of MMAs include bearings, gears, cams, bushings, seals, valves, nozzles, and pistons. |

| Title: | Electro-Spark Alloying Coatings for Erosion Resistant Impellers |
| Abstract: | Shaft-driven impeller technology is a critical component in a wide range of military and commercial equipment. The high-velocity impingement of dirt and debris, and their subsequent wear effect on the impeller have been documented not only on the V-22 Osprey, but other flight systems and military ground vehicles. The uniquely high RPMs associated with this titanium impeller design make it particularly susceptible to high wear. Due to the extraordinarily high impact velocities of particles on the titanium, most conventional coatings, typically mechanically bound to the substrate, will not provide protection to extend the life of the component. However, an emerging process, electro-spark alloying (ESA), is capable of imparting a high hardness surface of only a few thousandths of an inch which will offer full metallurgical bonding to the substrate with little or no heat-affected-zone (HAZ) typical of most coating processes. ESA also provides a nano-grained surface with enhanced wear properties over their larger-grained counterparts. The proposed effort will model the particle impact to assess coating design parameters, perform coupon level coating studies, and simulate the wear environment via high-velocity particle impingement tests. Successful candidates will proceed to Phase II development. Optimized ESA surfaces will provide the additional life necessary for the V-22 to meet its mission-related life-cycle goals. This development will readily transfer to a wide range of wear/impact applications such as: other military and commercial impellers, lawnmower blades, cutting tools, nozzles, etc. |

| Title: | Compressor Impeller Erosion Resistant Surface Treatment |
| Abstract: | Shaft driven compressors (SDCs) are used on aircraft for a variety of functions. Although air intakes for these compressors are equipped with particle separators, in dusty environments/storms, the separators are overtaxed and unable to completely remove dust particles leading to rapid erosion of impellers. This can lead to loss of function of critical components and potentially catastrophic system failure. Surmet proposes innovative conformal coatings for imparting high erosion resistance to the impellers. Preliminary erosion tests indicate high potential of these coatings for providing erosion resistance. In Phase I, Surmet will demonstrate feasibility of achieving high erosion resistance via fabrication of coated coupons and extensive microstructural, mechanical and erosion characterization. Surmet has teamed up with a major aircraft manufacturer to demonstrate applicability of the coating to a prototype component in Phase I Option. In Phase II, the coating technology will be optimized through coating and system level characterization of a large number of components. A Phase III commercialization plan will be developed for rapid insertion of the technology in operating aircraft. Shaft driven compressors (SDCs) are used in a variety of military and commercial aircraft. Development of erosion resistant coatings for SDCs will prevent rapid erosion and catastrophic system failure in dusty environments, prolonging component life and reducing life cycle costs. Erosion resistant coatings will also have application in commercial equipment such as pumps, compressors, energy generation equipment (erosive effluents), mining equipment, etc. |

| Title: | Auto-correlation of Elevation Data from Digital Stereo Imagery |
| Abstract: | Relative to the stated US Navy interests in auto-correlation of elevation data for support to the Cruise Missile Command and Control (PMA 281), our technical objectives offer a linear analytical approach to this SBIR. Our first objective is to conduct an operational requirements analysis to define the operating environment of the digital correlation solution and its interfaces to source data and target systems. Next, we will investigate the specific functional requirements that define the processes that must exist within the solution. Third, we will examine the performance requirements to include such variables as timing, output quality of the solution, impacts upon digital correlation results, estimation of improvement gains in minimizing interactive editing, and accuracy requirements. Fourth, we will investigate the PTAN requirements that will affect the output of the DEM required for the reference map. Finally, we will analyze the optimal digital correlation approaches as defined by the prior tasks. Under a planned Phase I Option, we will also focus on the architectural design for Phase II prototyping, and conduct a market survey quantifying the potential success of a related fielded product. A number of opportunities for a digital correlation solution exist in the marketplace. The most promising involves providing solutions to commercial satellite systems vendors and their value-added resellers and product generation partners for sale and resale. Also, remote sensing/GIS vendors should be receptive to reselling a solution as an add-on or replacement of their existing digital correlation capabilities. Lastly, DoD, intelligence, and defense mapping agencies worldwide are potential customers of bulk sales of the solution. During both Phase I (Option) and Phase II, research into all logical marketplaces will be performed to finalize anticipated revenue levels and per unit pricing. We believe at this point that the market value for the solution will be in the $7,500-$10,000/copy range, with embedded versions resold by partners for roughly 30-50% off standalone pricing. |

| Title: | A Device for In-Situ Evaluation of Vehicle Wiring Systems |
| Abstract: | Aircraft system wiring has become a primary concern for aircraft safety. The Air Force has identified aging wiring as a cause of aircraft fires and is a major driver of ownership costs. This proposal will explore making a passive Sentient Wiring Connector (SWC) that will instrument wiring in aging aircraft. The low cost, multi-sensory SWC has significant advantages over labor intensive and expensive ground based systems. The SWC can save millions of dollars in operations and support costs over the remaining life of the aircraft. The SWC will process data from multiple sensors into information used for detection of signs of aging. The SWC can be inserted into the wiring itself to check for wiring continuity, breaks in electromagnetic shielding, water in harnesses, cocked connectors, and corrosion as well as inspecting the health status of the wiring insulation. The SWC connected to subsystems (avionic unit, engine, transmission) will be able to monitor many of that system's vital health signs. Used in flight, the SWC will detect loose pins, intermittent problems, missing clamps, abrasion, and other factors impossible to detect during ground inspections. The SWC will also send processed information to a web-page database for continuous monitoring of the aging wiring. Aircraft certification, vehicle safety liability concerns are major reasons for utilization of the SWC technology. The product will have broad application in inspection of commercial and military aircraft. The SWC will be an enhancement to present health management systems. With minor changes in format the SWC will also have uses in monitoring wiring of ships, mass transit systems, vehicles and buildings. |

| Title: | Wiring Diagnostics Using the Smart Universal Sensor Interface (PR00-001) |
| Abstract: | We propose to research, design, and develop active and passive signal and cable diagnostic capabilities for our Smart Universal Sensor Interface (SUSI). SUSI is designed to accommodate more sensors than conventional avionics sensor units, using fewer wires, less power, and at greater data rates and shorter delays, while consuming less physical space. In addition, SUSI provides advanced features such as: upgrades to optical avionics networks, full compatibility with legacy systems such as AATIS, CAIS, 1553, and ARINC; serial sensor buses to further reduce wire count; smart functions such as described in the IEEE 1451.2 standard; and extensive local processing and data storage capability. SUSI is designed to be modular to a very high degree - even the network interface can be changed by simply replacing the network module. These advanced features can be used to implement diagnostics and health monitoring functions for a wide range of applications, including wiring diagnostics. Since SUSI integrates into the avionics system and is designed to take data and control actuators, there is no added overhead (weight, cost, etc.) for additional instrumentation. This system could provide critical data not only for safety purposes but for maintenance as well, thus helping to extend useful aircraft life. Both military and commercial aircraft could benefit from advanced smart sensor systems capable of providing real-time data on subsystem health. |

| Abstract: | Triton Systems proposes to develop novel, polymer-inorganic nanocomposite coatings for the polycarbonate and acrylic surfaces of the F-18 and other aircraft transparencies. Triton's polymer-inorganic nanocomposite contain nanometer scale inorganic filler particles that enhance the chemical resistance, abrasion resistance, and overall protective properties of the coatings. Our novel nanocomposite coatings will be solution-based and easy to apply on the F-18 transparency and will provide excellent optical transmission characteristics with minimal haze and no distortion. In addition, these coatings will improve flame resistance, and barrier to chemical and biological warfare agents. These coatings will significantly extend the service life of transparencies and reduce the operation and support costs of windshields and canopies in the field. These coatings will find application in a variety of other Navy, military and civilian applications such as aircraft windows, helicopter transparencies, vision block for vehicles, face shields and goggles for soldiers and chemical laboratories.

| Title: | Intelligent Tutoring System for Tactical Aircraft Training (ITS-AIR) |
| Abstract: | Technical Abstract (Limit your abstract to 200 words with no classified or proprietary information/data.) Benefits of low-cost, high-fidelity, self-contained deployable training units, such as TSTARS, include increased availability of on-location training with reductions in travel expenditures, personnel time lost at training locations, and geo-specific training centers costs. However, the cost of providing on-site personnel to assist the student represents a significant drawback of current simulation technology- particularly considering the reduced manning-level environment of current military budgets. But, this need not remain the norm, as prototypical simulators of the future will, themselves, be capable of adaptive training techniques best suited to current students needs without requiring assistance from specialized simulator personnel. SDS's ITS-AIR innovations, utilizing COTS components from Soar technology, USC, STOW/BMH and ModIOS within a rapid prototype environment through reuse of the SDS LiteFliteT Reconfigurable Flight Simulator, will be used for assessing an instructorless intelligent tutoring system. Prototyped intelligent agents will be utilized for investigations into reducing manning levels for deployed training systems. Further, Soar-based AIR-SF, STOW/ BMH tools and Motorola ModIOS tools will be used as the basis for After Action Review and mission rehearsal components. Use ofLiteFliteT will be provide leverage as a placeholder for the TSTARS system planned for Phase II. There are multiple classes of Commercial Applications for ITS-AIR associated technologies. Military Aviation, Commercial Air Carriers and General Aviation will be the first to benefit. ITS-AIR could be added as an option on existing or new aircraft simulators. Potential benefits include reduced manpower costs, enhanced performance, increased standards, and early teaching of optimal methods to pilots. In fact, ITS-AIR, when coupled with student pilot motion sensors and eye tracking technology, could provide a comprehensive method of measuring differences from expert performance in well defined training scenarios. The sale of turnkey systems-- ITS-AIR "Kits"--will allow early product commercialization, particularly within the commercial and general aviation markets. General transportation, including transports, freighters, recreational boats and racecars, would also benefit from the research and development done for aviation. SDS plans to identify numerous lucrative internet markets. These markets, like the aerial, marine and land markets, require extensive up-to-date domain databases. A potential avenue, which SDS plans to explore, is teaming with an organization(s) currently providing domain specific databases, utilizing intelligent agents to automatically retrieve updates. Since any computer based training program can benefit from the introduction of automatic operator assistance and adaptive training techniques, Intelligent Tutoring technology has broad-based appeal. For instance, aerospace systems can train new features. |

| Title: | Intelligent Tutoring System for Air Tactics |
| Abstract: | Next generation mission rehearsal training systems, such as the Transportable Strike Assault Rehearsal System (TSTARS), will be smaller and more easily reconfigured, so they can be deployed aboard aircraft carriers and used by pilots to configure and practice missions while at sea. However, if scarce and costly human instructors are required to operate these new systems and provide instructional feedback to pilots, the potential "any-time, any-place" benefits offered by these systems will be significantly reduced. SHAI proposes to develop an air tactical ITS (ITS-AIR) which would provide pilots with instructional feedback automatically and help them operate the simulator without human instructors. Our system will employ template-based student performance evaluation, automated feature extraction from the simulation data, temporal inference, application-specific knowledge editors, and adaptive instruction. This approach will result in a sophisticated tutoring system whose knowledge base can be maintained by SMEs without programming. SHAI will team with cognitive psychologists at Klein Associates who will help us carry out a preliminary Cognitive Task Analysis and provide relevant results of prior CTAs. Mr. Lloyd Prince, a former Naval aviator, will serve as a subject matter expert. We will design, develop, and demonstrate a prototype system which illustrates our approach. The aviation ITS technology developed for ITS-AIR will enable automated tutoring system add-on products which complement military and commercial aviation simulators, sold through simulator vendors and directly to military and commercial aviation end-user organizations. |

| Title: | Environmentally Insensitive Active Decluttering |
| Abstract: | Active sonar operations are a key to achieving effective USW performance in littoral waters. The performance of active sonar in these scenarios is often clutter limited. Most traditional active decluttering approaches have identified classification clues that are used to try to discriminate target echo returns from clutter echo returns. These approaches have historically suffered from performance sensitivity to changes in the environment and to limitations of the data used to tune the algorithms. DSR proposes an approach that will extend well-known detection theory concepts to the problem of active decluttering and classification. It turns out that some of these concepts have already been used in various classification implementations, though the implications of the detection theory performance were not pursued within the structure of the classification problem. DSR's effort will result in definition of MOE's, specification of processing algorithms, and evaluation of performance against existing sea data. Completion of this effort (Phase I and Phase II) will lead directly to integration of an environmentally robust active acoustic decluttering capability for the Navy's SH-60R Platform. |

| Title: | Environmentally Insensitive Active Decluttering |
| Abstract: | Active sonar systems face a significant decluttering problem especially when operating in shallow water. In future multi-static, multi-receiver search missions, the number of alerts is expected to increase dramatically. Tactical scenarios present a further complication because response time is critical and, as a result, classification in the fewest number of pings is crucially important. Historically, the decluttering issue has been addressed by estimating parameters of active acoustic returns and comparing those returns against thresholds. Unfortunately, these thresholds are highly sensitive to the environment. The proposed Phase I research intends to develop environmentally robust signal processing algorithms that significantly reduce clutter, improve detection, and perform quickly. To address these issues, the Phase I effort proposes three tasks. The first is to define a CFAR threshold based on the (possibly) non-Gaussian statistics of the matched filter or energy detector output. The second is to develop a classification metric based on acoustic returns for distinguishing targets from clutter. The third is application of an in-situ enhanced environmental model, which provides feedback to the classification metric for measurement and analysis. Each of these tasks will contribute to the SBIR goal, which is to reduce clutter and sensitivity to environmental conditions The anticipated benefits of the Phase I research include development of environmentally robust operator aids for significant clutter reduction, and improved detection and classification performance. This has benefit and applicability to a wide variety of Navy platforms and programs, including SH-60R. For future multi-static, multi-receiver search missions, 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. |

| Title: | Multistatic Operation |
| Abstract: | Active sonar operations are a key to achieving effective USW performance in littoral waters. A capability that has been largely untapped in USW operations is bistatic operations between the SH-60R platform and surface ship assets. Historically, bistatic studies have addressed improvement of wide-area search performance. In this effort, DSR will instead investigate the performance improvements that bistatic operations can provide to the USW Middle and End game scenarios. DSR will consider an SH-60R platform acting bistatically with a surface ship that has both AN/SQS-53C and MFTA subsytems. The Middle and End game scenarios provide enough information about the target that determination of source/receiver deployments yielding desirable bistatic geometries becomes feasible. DSR will define MOE's, develop a performance model, evaluate potential performance improvement, and develop a preliminary concept for an Integrated Bistatic Post- Processing System. This new Integrated Bistatic Post-Processing System will also be able to assist the operator as a planning aid since it will determine recommended source/receiver deployment strategies. The processing will select desirable deployment strategies based on the effect of bistatic geometry on target strength, Doppler shift, reverberation level, localization error, target motion, and platform covertness. Completion of this effort (Phase I and Phase II) will lead directly to introduction of bistatic planning and bistatic processing capability into the SH-60R Platform. |

| Title: | Multistatic Operation |
| Abstract: | Multistatic/Multiplatform ASW capabilities are needed to counter the improvement in capability of enemy submarines deployed by potential adversaries. The need exists for systems that provide a wide area search capability while at the same time providing sufficient standoff distances for friendly forces. Multistatic/Multiplatform operations can fulfill this need by providing opportunities for multiple target detections, improved localization, and improved classification. Each ASW platform brings unique capabilities to the conduct of the mission. For example, the air platforms are highly mobile and are capable of searching a vast area by deploying a large field of source and receive sensors. The surface and subsurface platforms have the capability to produce high source level and deploy receive arrays with high directivity gain. If the Navy is to continue to keep pace with the improving submarine threat, there clearly exists a need to develop systems that combine the inherent strengths of each platform to improve overall ASW mission effectiveness. In this SBIR we address two multistatic scenarios to a level of detail necessary to assess the potential improvement in ASW effectiveness. The product of this SBIR is intended to be of use to the SH-60R and surface platforms equipped with the SQS-53C sonar. Making SH-60R and surface platform capable of integrated ASW operations will significantly enhance the ASW performance of both platforms in both the search and localization phases of the mission. The innovative concepts under development in this SBIR are intended to enhance the effectiveness of this multiplatform system. |

| Title: | Tracking Multisensor Data |
| Abstract: | Evolutionary algorithms are proposed to assist in tracking multisensor data. A common protocol is for a tracker to receive time-sequenced reports from multiple sensors (often of different types). Each sensor may or may not report a detection. The tracking problem is to assign each detection to a track, or start a new track. The number of different ways for combining targets into tracks over time increases very rapidly. Such combinatorial problems are often well suited for evolutionary algorithms. The approach proposed here is to evolve tracks online as data are acquired and adapt those tracks in light of new data as they become available. Scalable tracking based on observations from mutliple different sensors is useful in a variety of commercial shipping applications, as well as satellite overhead imagery. |

| Title: | A Context-Adaptive Multiple-Hypothesis Approach to Multisensor Air ASW Tracking and Data Fusion |
| Abstract: | The Navy needs an effective integrated approach to data fusion and tracking for a heterogeneous air-deployed sensor field. The data fusion architecture must properly handle bearing-only, range-bearing, and other multistatic measurement types, must model sensor-dependent measurement characteristics and accuracies, and should use data association/fusion algorithms appropriately matched to the current sensor, measurement, and environmental characteristics. ORINCON proposes a solution based on an algorithm-adaptive variant of a proven multiple measurement-type multiple-hypothesis tracking capability. Specifically, ORINCON proposes to develop and demonstrate a prototype Air ASW adaptive fusion architecture enabling dynamic intelligent selection and switching among multiple kinematic data fusion algorithms based on the situational context (for example, currently available measurements, or clutter density). ORINCON has shown that adaptive fusion algorithm selection and switching leads to significant improvements in multisensor tracking performance; the approach will enable effective fusion across dipping sonars, sonobuoy sources/receivers, and other acoustic or nonacoustic sensors. ORINCON will demonstrate the prototype on real recorded data, and will quantify performance using specific track quality metrics. ORINCON will optionally quantify performance so as to infer maximum measurement gaps, and therefore recommendations for field deployment strategies. Phase II will include additional kinematic fusion algorithm and attribute/classification fusion algorithm extensions. The proposed fusion architecture will lead to dramatically improved performance, critical for the projected full spectrum dominance under Joint Vision 2010. The open, modular architecture provides for flexibility and growth with the SH-60 or MPA systems. The Navy will experience payoffs via the leveraging of existing technology and the applicability to surface-, subsurface- and land-based systems. Finally, the data fusion architecture could be used for nonmilitary multisensor tracking applications such as seismic exploration or off-coast drug interdiction. |

| Title: | Autonomous Neurofuzzy System for Tracking Multisensor Data |
| Abstract: | In response to the U.S. Navy solicitation for Tracking Multisensor Data, Physical Optics Corporation (POC) proposes to develop an autonomous multisensor tracking system (AMTS). The proposed AMTS will combine POC's proprietary neurofuzzy control and distributed data tracking methodologies. The proposed neurofuzzy AMTS will have three innovative advantages: autonomous tracking capability, minimizing operator interaction; autonomous incorporation of information from both passive and active sonobuoys; autonomous multistatic operation with sonobuoys and dipping sonars. The core of the AMTS is the Neurofuzzy Tracking Control System (NTCS), which consists of a signal validation module, a data alignment module, a data association in module, and a data correlation module. These NTCS modules control each step of overall tracking based on multisensor data, making use of the expertise embedded by POC's neurofuzzy technology. In Phase I, POC will demonstrate the feasibility of AMTS by means of computer simulation. In Phase II, POC will build a fieldable AMTS based on Phase I results. The immediate application for AMTS is ASW tracking based on data streams from multiple sonobuoys and dipping sonars. The AMTS can also be used for automatic multiple target tracking, air traffic control, satellite tracking, and inventory tracking. |

| Title: | Military Utility of Automatic Dependent Surveillance - Broadcast (ADS-B) |
| Abstract: | Navy and Marine Corps tactical aircraft must make a significant transition in avionics functionality if they intend to retain access to worldwide sovereign controlled airspace. The stand-alone avionics systems of today must be replaced with integrated sensors and displays that can achieve the new required level of performance in Communications, Navigation, and Surveillance (CNS). Self-reporting surveillance known as Automatic Dependent Surveillance-Broadcast (ADS-B) with a Cockpit Display of Traffic Information (CDTI) will require integrated systems. This SBIR will study the impact of Mode S and ADS-B on current military Tactics, Techniques, and Procedures (TTP) and evaluate their potential military utility. Phase II of this SBIR will install integrated ADS-B in a Navy aircraft and demonstrate its functionality for both civil and military operations. Phase III, the commercialization effort, will establish DCS Corporation as a center of excellence in CNS core integration architecture, systems engineering services, and computer based training devices ready to assist other military and civilian platforms make this transition. This SBIR will allow the military to study the mission utility and impact of ADS-B and CDTI in current operational environments and develop an affordable path to integrate this new level of situational awareness into other fleet aircraft. ADS-B is based on civil technology. The hardware and software developed and demonstrated during this SBIR effort should have many applications for General and Business aviation. The Cargo Airlines Association is evaluating the potential of ADS-B for traffic awareness and deconfliction. ADS-B utility for general aviation is being evaluated in Alaska with the Capstone Program. Over the next 10 years there will be many business opportunities associated with ADS-B functionality, including systems engineering services, aircraft modifications, computer based training and unique software applications. |

| Title: | Military Utility of Automatic Dependent Surveillance - Broadcast (ADS-B) |
| Abstract: | ADS-B technology holds great promise for providing the U.S. Navy with a number of significant benefits. These benefits are derived from an improved tactical picture for both command and control personnel and pilots. They include improved safety through better situational awareness and reduced pilot workload, and improvements in tactics, techniques and procedures, such as higher confidence levels in the tactical picture that might allow engagement of the enemy without visual identification. Other benefits include time and resource efficiencies, collision avoidance, range clearance and compatibility with aircraft operating in the NAS and civil aircraft in foreign airspace. Globally, ADS-B holds the promise of being the core of a new global surveillance network, and the military should evaluate mission needs at this stage during the formative stages of ADS-B development and implementation. Rannoch has unique insight into the future of ADS-B. We actively support RTCA committees on ADS-B standards development. We have designed, manufactured, and deployed ADS-B equipment. Our rapid avionics prototyping capabilities as well as our tools and techniques enable us to assess the military effectiveness of ADS-B for the Navy. As new common avionics programs are being considered, it is time to start laying the groundwork for Navy ADS-B implementation. Anticipated Benefits: Improved tactical picture; Reduction in misidentified targets; Reduction in False Replies Uncorrelated in Time (FRUIT) ; Reduction in overlapping (garbled) signals; Improved command and control in a military theater of operations ; Saves time and assets by reducing the number of missions required to identify unknown targets ; May enable the use of beyond visual range weapons; Improved situational awareness for controllers and pilots; Collision avoidance; Reduces pilot workload ; Range clearance; Compatibility with civil aircraft operating in NAS and foreign airspace. Commercial Applications: Provides enhanced radar coverage in areas that are below the sweep angle of conventional terminal or enroute radar antennas; Provides radar coverage for airports without conventional radar; Provides an inexpensive air traffic control radar system for countries that do not have a ground based radar infrastructure; Provides enhanced situational awareness to airport operations vehicles and airline support vehicles to help eliminate the growing problem of runway incursions; Improves airline gate operations, enabling the monitoring of all aircraft and vehicles in the gate area; Provides collision avoidance capabilities similar to TCAS, but sized and priced for smaller general aviation aircraft . |

| Title: | Military Utility of Automatic Dependent Surveillance - Broadcast (ADS-B) |
| Abstract: | Sensis proposes an ADS-B system which meets the needs of the military. The system proposed is a complete replacement to the current IFF system for the purposes of situational awareness and combat identification. The proposed system uses a Low Probability of Detection (LPD) waveform and encryption to protect the data from interception or spoofing from enemy forces. The proposed system has the potential of being installed in every US military aircraft in addition to allied aircraft as well as in ground infrustructure throughout the world. In addition to the military market, the radio technology developed has potential markets in civilian aviation. These markets include its use in Sensis's airport vehicle tracking system and as an alternative civil aviation ADS-B system. |

| Title: | Low-Cost Precision Missile Trackers for Directional Infrared Countermeasures (DIRCM) |
| Abstract: | There is a need for IRCM system counter threats that are difficult to defeat using conventional IRCM techniques. Because the new generation of threats are more capable, IRCM energy must be directed at the missile threat to obtain sufficient energy on target to cause it to miss the aircraft. In order to attain the energy on target, an IR jammer must be able to track the threat missile with enough accuracy to point a laser at the seeker. Current IR detectors in tracking sensors are expensive and must be cooled in order to achieve the sensitivity needed to track IR missile threats in all phases of flight. The coolers used with these detectors are the least reliable part of the sensor. These coolers cause a reduction in the reliability of the tracking sensor, increase maintenance requirements, and increase the cost of the sensors. Developing an uncooled IR detector for the tracking sensor will reduce the design complexity, reduce the production costs and increase the reliability of the tracking sensor. The miniaturized uncooled image intensified charge coupled device (I2CCD) system that is the subject of this Phase I SBIR will provide low cost, compact, high reliability precision tracking device for a variety of defense and civil airborne platforms. Beyond the obvious protection of fixed and rotary wing military assets, the precision tracker can support antiterrorist assets, coastal reconnaissance aircraft, and governmental and personal aircraft flying in high-risk areas worldwide. |

| Title: | Low-Cost Precision Missile Trackers for Directional Infrared Countermeasures (DIRCM) |
| Abstract: | Missile warning and countermeasure (CM) systems play a critical role in the survival of many ground- and air-based vehicles operating in hostile environments. The CM protection may take the form of an active system like a laser source intended to disrupt the guidance of an approaching missile. To direct the laser at the approaching threat missile, the CM system must be able to accurately track the incoming missile. To track the incoming missile, IR sensors may be used. For improved sensitivity, these sensors employ a cooling system, which increases the cost, weight, and complexity of the sensor, while adversely affecting its reliability. We propose to assess the suitability of uncooled sensors for tracking incoming missiles. Specifically, we will consider the use of image intensified CCD (I2CCD) sensors which are relatively mature and inexpensive. Through the proposed effort, we will accomplish several objectives - Determine the signature of several threat missiles in the waveband from 0.5 - 1.1m. - Survey the current capabilities of I2CCD cameras operating in these wavelengths. - Assess the suitability of I2CCDs for tracking the threat missile signatures - Assess the angular tracking precision that can be obtained using an I2DCCD The proposed research offers potential savings in cost and improved reliability of optical tracking systems compared to a cooled IR sensor. These advantages are multiplied when the potential replacement can be made on a class of system that is widely deployed, for which cost, weight, and size, and reliability are important concerns. The suitability of the I2CCD sensor for potential applications depends on the in-band scene radiance, both for the objects of interest and any background. For the proposed research program, this radiance comes from tactical missiles - and has not previously been well-characterized in the proposed waveband. Thus, this effort will contribute to the body of knowledge regarding tactical missile signatures. The benefits of refining and applying uncooled IR cameras are very commercially viable - reduced cost, size, and reliability - and apply to a variety of different potential applications. As remote sensing and video surveillance become more accessible, the uncooled IR systems offer a practical and inexpensive means for extending the observations into the IR wavelengths for low-light or night-time, unilluminated situations. |

| Title: | Middle Game Localization Utilizing Air Deployable Active Receiver (ADAR) |
| Abstract: | The objective of this research is the evaluation of the passive capabilities of the ADAR sensor, and the specification of algorithms and systems for utilizing the passive data received by the sensor. AHA will employ advanced simulation and modeling techniques to perform the evaluation part of this research, evaluating both the existing passive capability of the ADAR buoy, and the potential capability given the implementation of processing improvements. The evaluation will ensure the correct assessment of true value added to the total ASW mission through the inclusion of each phase of the mission. Measured data from appropriate littoral environments will be used to guarantee the applicability of modeled results to the real world. In the algorithm specification phase of this research, AHA will define an ADAR passive processing system architecture that includes the core signal processing functions for passive signal detection and a design that will readily accept future algorithm improvements. We will also define and conduct an initial performance assessment of candidate spatial processing, signal detection, and classification/localization algorithms that will provide a strong R&D baseline for passive ADAR. This performance assessment will also provide passive sonar equation variables for use in the model-based evaluation part of the research. The anticipated benefits of this research are the specification of advanced signal processing algorithms for the use of passive data in Air ASW missions. In addition, advanced modeling techniques will contribute to modeling efforts both within the Air ASW community and throughout the Navy. The processing algorithms identified through this research will be useful in adding capability to the IEER mission. In the future, Navy programs and research efforts such as the Advanced EER (AEER) and the Super-ADAR will benefit from this research in algorithm development. |

| Title: | Middle Game Localization Utilizing Air Deployable Active Receiver (ADAR) |
| Abstract: | This SBIR proposes the development of a passive processing, detection, localization, classification, and display format system for the Air Deployable Active Receiver (ADAR) sonobuoy. This system will be capable of operating concurrently with the active processor but in the background with minimal or no operator action required permitting the operators to concentrate on active detection. This proposed system would be compatible with existing aircraft processing system, which utilize the ADAR sonobuoys. The system is unique because it would operate autonomously, provide a passive capability for the ADAR sonobuoy, and utilize a localize before classification concept. This proposal includes quantifying the passive ADAR capability in shallow water against slow quiet targets; defining and developing new algorithms required to provide autonomous, full spectrum passive detection, localization and classification; estimating the signal processing resources required to perform the task; and defining the interface with the existing ADAR active operator tasking. The proposed system would provide enhanced passive detection, additional classification capabilities, and submarine speed denial capability. This signal processing will satisfy a critical need for a behind the scene multi-spectral passive acoustic signal processor algorithm utilizing the array gain of the existing ADAR sonobuoy and establishing a full spectrum active/passive capability. Commercial markets can benefit by utilizing the autonomous architecture and signal processing techniques for developing "smart" household consumer products, to conduct multi purpose tasking during marine mammal operations, off shore oil exploration/drilling, cable/pipe laying surveys and coastal environmental studies. |

| Title: | Joint Optical Air Data System |
| Abstract: | The Molecular Optical Air Data System (MOADS) is a compact optical instrument that can directly measure wind speed and direction, temperature, and density of the air ahead of an aircraft. From these measurements, all of the air data products can be determined. MOADS is a direct detection system (i.e., it is based on incoherent rather than coherent detection) and does not require the presence of aerosols to make these measurements. This low observable system replaces pitot probe and alpha/beta sensors and has the growth potential for wind shear detection and gust alleviation/clear air turbulence. A significant level of investment has gone into the existing MOADS prototype, which is scheduled for a flight demonstration in March, 2000. This Phase I effort will result in a design for the next generation MOADS instrument based on JSF air data requirements. Based on lessons learned from the existing prototype, specific improvements have been identified that will increase the accuracy and update rate of the next system. A technology maturation path for critical items, such as the laser, will also be identified. Through the Alternative Technology Air Data System (ATADS) study and current programs, MOADS was shown to be a viable option as an Air Data System by meeting the performance and installation requirements of a high-dynamics, tactical aircraft. The potential exists, therefore, for application toward JSF and other tactical and commercial aircraft. The opportunity presented in this SBIR is also significant in that it allows us to begin considering other applications of MOADS in addition to measuring air data products. The multiple-use of MOADS as a wind shear, gust alleviation, clear air turbulence sensor greatly expands the market potential into the commercial realm. |

| Title: | RAYLEIGH-MIE LIDAR FOR OPTICAL AIR DATA |
| Abstract: | OPHIR Corporation is proposing to build a system that will use optical remote sensing to replace traditional sensors now used on jet aircraft for collecting air data. The proposed system will collect light scattered from an ultraviolet laser beam by both air molecules and aerosols ahead of the aircraft in undisturbed air. The Rayleigh (air) and Mie (aerosol) scattering will be separated from each other by using their different frequency response characteristics. The aircraft's airspeed will be found from the Doppler shift of both the Rayleigh and Mie scattering, and will therefore not fail if the air becomes too clean because of lack of aerosols. Measuring the airspeed on three perpendicular axes will allow the aircraft orientation relative to the air to be measured. Then, by fitting the measured Rayleigh lineshape with a theoretical lineshape, the air pressure and temperature will be found. While traditional air data sensors perform well, they have significant limitations in performance and maintainability that impact safety and life cycle costs. This is true for both commercial and military jet aircraft. In addition, traditional sensors have proven difficult and expensive to integrate onto low-observable aircraft. In this phase I effort, the potential to overcome all of these limitations with an optical air data system (OADS) will be demonstrated by analysis and its baseline design completed. The proposed system has commercial application in three Aerospace markets: Flight Test Groups, Military Aircraft, and Commercial Aircraft. The system has the potential to overcome limitations in traditional air data systems at considerable economic benefit. A successful system could one day become a new air data system standard for aircraft. |

| Title: | High-Power UV Lasers for OADS |
| Abstract: | The benefits of using an Optical Air Data System (OADS) on new high-performance aircraft will never be realized until a simple, rugged, light-weight laser source has been developed and demonstrated. Systems currently under test can provide update rates for velocity and angle-of-attack that are well below those required for flight, and it is estimated that on the order of 5 watts of average power near 250 nm will be required in a fielded OADS. Although this power level has been demonstrated by several laboratories, shrinking such a system, and improving its reliability and tolerance of temperature fluctuations, vibration, and shock is more than a simple engineering exercise. Fundamental changes in resonator design, thermal management, and especially harmonic conversion technique will be required to meet this goal. Essentially, the laser source needs to be redesigned from the ground up, with the OADS requirements in mind. We intend to replace the oscillator/amplifier used in our commercial UV laser with a single, high-power oscillator, and employ a resonant quadrupler containing both the nonlinear crystals LBO and CLBO. We will also investigate line-narrowing, and, for the optional task, the development of a tuning capability. Potential commercial applications include via hole drilling and other semi-conductor industry materials processing, UV photolithography, and stereolithography. Lidar applications in addition to OADS include pollution detection, chemical and biological weapons detection, and upper-atmosphere studies. |

| Title: | Ultra-sensitive OPA Lidar Receiver |
| Abstract: | Significant improvements in the detection capability of weak LIDAR return signals can be achieved by optically amplifying the signal prior to detection. An optical parametric amplifier (OPA) can provide high gain, low noise, and wavelength-agile operation with spectral and spatial filtering. CTI proposes to develop an OPA-enhanced receiver that will increase the sensitivity of LIDAR detection by almost 30 dB. However, an improvement in the nonlinear optical (NLO) conversion is required to reduce the pump power requirements to practical values. The proposed Phase I effort will investigate several technology paths to achieve this goal: (1) photonic bandgap semiconductor heterostructures, (2) new phase-matching techniques and novel geometries in semiconductor materials, and (3) NLO waveguide architectures. CTI has successfully completed a program that investigated and demonstrated a NLO converter to frequency-shift eye-safe LIDAR signals to visible wavelengths to greatly enhance the detection sensitivity. Furthermore, our proven ability to design and engineer rugged, flight-qualified LIDAR systems will ensure a successful overall development program. In Phase I, CTI will conduct detailed analyses and laboratory demonstrations to evaluate next-generation OPA designs. In Phase II, an ultra-sensitive OPA receiver will be tested and delivered. (1) increase detection sensitivity in eye-safe laser radar systems, (2) reduce laser source requirements for military and industrial active imaging, thus reducing both system size and cost, (3) provide new technological approaches for designing ultra-sensitive mid-infrared detectors enabling new commercial products. |

| Title: | A Field-Oriented Operator-Machine Interface Architecture for Multisensor, Multibeam Air ASW Systems |
| Abstract: | Multistatic, air-deployed sonobuoy fields provide a powerful and unique means of detecting and classifying the shallow-water ASW threat. However, the typical number of sensors deployed and the increasing number of sensor beams processed place unreasonable operational demands on the user and may result in unacceptably long decision times. The Navy is in need of a new Air ASW operator-machine interface (OMI) approach that reduces search time and eliminates beam paging, that facilitates full field search and analysis, and that provides local environmental or historical context for immediate comparison. ORINCON proposes an OMI concept centered on the geographic scene. The concept allows the operator to view all sensor data simultaneously and interrogate this data in parallel based on his prioritization or as prompted by automated classifiers. The OMI concept uses display intensity and color to represent information from multiple sensors (raw or normalized data), automated classifiers (providing interrogation prioritization), trackers (providing historical context), and environmental databases (providing environmental context such as bathymetry or predicted signal excess). ORINCON will develop display requirements for this approach, identify typical field search sequences, and prototype the resulting display and search sequence concept. A fully operational display architecture will be achieved in Phase II. An improved OMI will result in improved Air ASW operator performance, reduced detection and classification time late, and reduced total operating cost even as sensor technology improves and becomes more complex. Efficient, effective methods for displaying time-critical tactical information and increasing the information coding dimensions via color and texture are also marketable far beyond the sonobuoy processing application. Examples include future nonacoustic sensor displays (radar, electronic combat, EO/IR) and enhanced tactical and operational decision making displays for area air defense and surface warfare missions. |

| Title: | Multibeam Sonobuoy Operator Displays |
| Abstract: | Acoustic Undersea Warfare (USW) with sonobuoys is characterized by a large amount of real time data, containing intermittent contact to a target of interest from geographically separated receivers. Methods that improve the communication bandwidth between the USW system and the operator such as advanced data visualization and spatialized audio have not been employed. These conditions establish a significant opportunity to improve the "operational effectiveness" of USW with a relatively low investment. The addition of automation has the potential to dramatically increase the search efficiency of the operator by reducing the need for manual data navigation for search. Since neither automation nor manual detection can address all cases, these capabilities need to be integrated to complement and support each other. Automation and the use of advanced display concepts to simplify the Operator Machine Interface (OMI) are required to streamline the process and present a unified tactical picture to enable a single operator to manage all sensors and contacts. This unified tactical picture can be merged with the battlegroup tactical picture held by the ASWC on the command ship in a net centric warfare domain such as that being created by the Advanced Undersea Warfare Concepts (AUSWC) initiative. The benefits of the products of this SBIR are not confined to the NAVAIR community, but rather, span the entire UnderSea Warfare (USW) community. There is an opportunity to improve the "effectiveness" of the Fleet with a relatively low investment and guarantee continued tactical superiority. The multiple sonobuoy management displays developed under this SBIR will directly support the Advanced Undersea Warfare Concepts (AUSWC) initiatives currently underway in the Navy advanced development community by providing each participating vessel in the USW Internet with a means of viewing this data, maximizing the effectiveness of interplatform collaboration in the sonobuoy information domain. The results of this project are anticipated to have application to both commercial and military systems. Initially, this product would be best applied to government agencies and DoD where real tactical superiority issues in ASW hang in the balance. As such, initial customers are intended to be PMA-264 and PMA-290 programs. Since the research is targeted towards displays, this topic could be used to aid battlefield assessment, war gaming, and radar systems. |

| Title: | Wavelet Compressions to Increase Desktop Personal Computer (PC) Real-Time Texture and Terrain Paging |
| Abstract: | LNK Corporation, Inc., in conjunction with JRM Enterprises, Inc. and MultiGen, proposes to develop a wavelet compression library which will be able to support Open GL and Direct 3D rendering on commercially available low cost PC boards. This library will extend LNK's existing wavelet compression algorithms, which have been used to compress hyperspectral sensor data, digital elevation models, and image files which may be used as texture maps. The library will also support material based classification and region of interest definition, used in sensor simulation. While lossless compression of 2:1 can be readily achieved, the LNK Team will explore hardware-specific optimization and scene fidelity tradeoffs that permit order-of-magnitude improvements in compression ratio, enabling multiresolution mip-mapped terrain databases to be rendered at frame rates appropriate to tactical aircraft simulation. In Phase I, LNK will develop an experimentation testbed based on a PC platform using commercially available runtime APIs to explore database paging, system architecture, and software design approaches, collect metrics on perceived and positional accuracy of rendered databases, and identify likely NAVAIR systems and programs for Phase II development, testing, and utilization. The technologies to be developed as part of this effort have very broad commercial application, and the availability of real-time graphics and advanced networking connectivity in PC and desktop environments creates a wonderful array of new possibilities for commercial product development, especially in the education and training, and commercial gaming markets. The collaboration capabilities to be developed under this Phase I effort go far beyond currently existing collaborative design and learning tools, and represent the next wave of distributed desktop software environments which take advantage of emerging DoD practices such as the DMSO High Level Architecture. Our product goal is to create software products and services which facilitate both DoD and other desktop customer needs for interactive collaborative environments. |

| Title: | Wavelet Compressions to Increase Desktop Personal Computer (PC) Real-Time Texture and Terrain Paging |
| Abstract: | Increased use of aerial photography and satellite imagery in visual simulation has created problems for low-cost PC based systems. Although the performance of low-cost graphics systems is adequate for real-time interactive visualization tasks, the immense disk and memory configurations to support image-based databases are a major cost and technological obstruction. This proposal will investigate wavelet compression/decompression in a database paging scheme for real-time applications with potential for this capability to be hardware accelerated in Phase II. TERREX has already developed and successfully commercialized database generation software (Terra Vista) and a run-time paging format (TerraPage) which it proposes to extend through this SBIR contract. Our proposal is innovative as it a) promotes a multi-vendor runtime solution with open-source, public domain APIs, b) the solution is backed up by a commercially successful database generation system, and c) the proposed applications include much larger markets such as PC games and Geographic Information systems which will give this development effort a much stronger potential to be adapted to hardware and commercialized in later phases. TERREX has technical expertise and existing commercial products highly complementary to this SBIR topic. The company has an outstanding record of developing commercial software products for real-time interactive 3D simulation. The Phase I research will provide an initial design for a wavelet compression scheme tied to a paging system for run-time applications. A prototype system will be implemented and demonstrated at the end of Phase I by extending TERREX' existing commercial database generation software and paging format/APIs. This demonstration capability should provide quantifiable results on the technical viability of the wavelet compression scheme, any issues/problems related to its use in real-time 3D applications, and an assesment of its further potential development as a hardware accelerated compression/decompression engine in Phase II and Phase III of the project. Potential post applications for the wavelet compression technology proposed herein lie in any field in which large 3D datasets are combined with high-resolution imagery in a real-time, interactive environment. This most clearly affects the Modeling and Simulation community, the Geographic Information Systems (GIS) community, and in Computer Game Software. Wavelet compression promises image size reduction which will dramatically affect the amount and quality of imagery which can be used on interactive PC based visual applications. |

| Title: | Compact Infrared Countermeasure (IRCM) Jam Head |
| Abstract: | Tactical aircraft DIRCM systems require a compact, high-power laser source in the mid-IR band. Current IRCM lasers are costly and exceed weight, space and power constraints of Navy tactical aircraft. Phase I will conduct the necessary analyses and investigations to confirm the utility of the Lockheed Martin midIR semiconductor compact laser subsystem and commercial off the shelf CCD sensors and gimbals to fulfill this critical role. The various subsystems which comprise this solution will be integrated on a single optical bench requiring only a two-axis gimbal. Proof of concept will include atmospheric propagation analysis to define optimum lasing wavelengths and ensure sufficient J/S in real-life environments. LOWTRAN 7 and/or HITRAN atmospheric propagation models will be used to run the appropriate simulations. Additionally, overall system hardware and software requirements will be defined and preliminary real estate analyses will be conducted to verify the feasibility of integrating the miniaturized IRCM into the existing USN AGILE EYE jam head. The miniaturized IR countermeasure system that is the subject of this Phase I SBIR will provide low cost, onboard protection for a variety of defense and civil airborne platforms. Beyond the obvious protection of fixed and rotary wing military assets, the MIRCM is applicable to antiterrorist assets, coastal reconnaissance aircraft, and governmental and personal aircraft flying in high-risk areas worldwide. |

Existing scanners, either mechanical (swinging mirror), electro-optic, liquid crystal, or acousto-optic, have certain limitations, and none of them satisfies military requirements for speed, resolution, range, effectiveness, and reliability. To overcome existing limitations, Physical Optics Corporation (POC) proposes to utilize the exceptional magneto-optic and magneto-elastic qualities of a certain class of metallic oxides. These qualities will lead to the excitation of a dynamic grating of local magnetic moments by propagating in the material an acoustic wave, and electronically tuning the spatial period of that grating by altering either the acoustic wavelength or the applied DC magnetic field. Thus, for the first time, two independent methods of beam scanning will be applied in a single element. In Phase I, POC will demonstrate the effective diffraction of infrared radiation on a magnetic grating induced by acoustic waves and wideband steering of the angle of diffraction by tuning of the driving (the piezotransducer) RF frequency and/or variation of the applied magnetic field. In addition to jamming, immediate military applications of the proposed scanner include missile seekers, target recognition, reconnaissance, and surveillance. POC's approach has the potential to reduce the size and power consumption of airborne and space-based jamming/tracking systems. Commercial applications include remote sensing, security systems, and switches for fiber-optic communication links. |

| Title: | Solid-State Imaging Array for Laser Radar Applications |
| Abstract: | This is a proposal for a very compact, low-power, High Range-resolution, Laser Radar (HRLR). The proposed preliminary design meets the solicitation requirements, namely a 5x 5 solid-state-array detector hybridized to a 5 x 5, 25-um pitch unit cell readout array. The readout array has the capability of 7.5-cm range resolution. Return-time data is multiplexed off the readout and only one output is required. Three options that could increase the performance of the 3-D imaging ladar system are suggested. The Phase I effort will include trade studies to optimize the sensor, the readout and the drive and output electronics. The readout will be designed and laid out in Phase I. The proposed $30,000, optional program includes the fabrication and performance-verification testing of the 5 x 5 readout array. Military applications of the HRLR imaging system and their civilian counterparts are in surveillance. There is also civilian application at airports - in support of safe takeoffs and landings - in robotic vision and in manufacturing. Radar does not have the resolution that could be achieved with a laser system. It is also quite possible that laser radar 3-D imaging systems will be used in future motor vehicles; penetration of small-particle fog is better at 1.55 um than at visible wavelengths. |

| Title: | Solid State Imaging Array for Laser Radar Applications |
| Abstract: | Sensors Unlimited will develop and deliver a 5x5 InGaAs avalanche photodiode (APD) array for use in eye-safe laser rangefinders. The avalanche photodiodes will be fabricated using a process virtually identical to our current production focal plane array process. Thus, the reliable operation of the arrays will be assured. The InGaAs APDs will have primary dark currents below 1 nA, avalanche gains in excess of 20, responsivity >15A/W at a wavelength of 1.55 æm, and electrical bandwidths >2GHz. In Phase I the APDs will be fabricated in a 5x5 array and bump-bonded to a Si fanout for APD characterization. The final deliverable in Phase I will be a packaged 5x5 array with access to the 25 array elements via package pins. In Phase II, we will develop a readout circuit using small cell GaAs transimpedence amplifiers with scalability to arrays as large as 64x64 elements. The larger APD arrays will be hybridized to the readout ICs using our flip-chip indium bump process. In addition to the utility of InGaAs APD arrays in laser radar systems, there is a tremendous opportunity for commercialization of linear arrays of APDs in the field of fiber optic telecommunications. Currently deployed Dense Wavelength Division Multiplexed (DWDM) systems operate in the wavelength band of 1.530 æm - 1.565 æm and use single element InGaAs p-i-n and APD based receivers. The ability to manufacture large arrays of receivers is ideal for such systems, as the benefits of reduced power consumption, reduction of interconnections, and reduced electrical parasitics are easily realized in hybrid integrated systems. The advantage of APDs over p-i-ns is the same in telecom as it is in LADAR: an improvement in the sensitivity of the optical receiver. The amplifier architecture developed within this program is directly applicable to use in DWDM systems in linear array devices. |

| Title: | Obsolete Electronic Parts Automated Functional Replacement System |
| Abstract: | EDAptive Computing, Inc. (EDAptive), and Dr. Perry Alexander of the University of Kansas present a unique and commercially viable solution to the problem of automatically replacing obsolete legacy boards in weapon systems. Our Electronic Design Automation tools for Electronic Parts Obsolescence (EDA4EPO) program will apply an innovative and integrated collection of several Electronic Design Automation (EDA) tools and languages, under development, to the problem of Electronic Parts Obsolescence (EPO). Specifically, we propose to research and develop an iterative solution, which will employ three key emerging and essential technologies for automation in the future, namely (1) the industry-, academia-, and government-sponsored Rosetta, an emerging standard System Level Design Language (SLDL) for specification of obsolete boards, (2) the Defense Advanced Research Projects Agency (DARPA)-sponsored, EDAptive SOCCER tool suite for specification-based search and retrieval of functionally equivalent parts, and (3) the Air Force (AF)-sponsored Design Verification Test Generation (DVTG) tool to validate board specification in Rosetta as well as SOCCER-generated, functionally-equivalent boards. We have discussed our technical and commercialization approach with potential customers and partners have found endorsement and early support for it among them. Maturation and integration of tools and languages proposed under this effort will alleviate the electronics parts obsolescence problem and reduce the cost of addressing it by at least an order of magnitude. In addition to DoD applications, the proposed system could be used for sustainment and post-production support of any electronic system, as well semi-automated synthesis of electronic systems starting with a formal specification. |

| Title: | Automated Functional Replacement (AFR) of Obsolete Parts Through Virtual Prototyping: A Study. |
| Abstract: | VP Technologies, Inc., is currently a contractor on the USAF Electronics Parts Obsolescence Initiative (EPOI, 1998-2001) and has also been selected a tier 1 subcontractor by Lockheed Martin (E&M, Orlando, FL) for its AMCE Parts Obsolescence (PO) Pilot Programs (JASSM & LOCAAS, 2000-2002). We are thus able to apply our extensive experience in combating electronics parts obsolescence at chip and board/subsystem levels, and also to leverage our partnerships with leading defense contractors, to develop a comprehensive solution to the problem of automated functional replacement (AFR) of obsolete parts. An innovative approach based on virtual prototyping technologies is proposed as part of this SBIR Phase I effort. The AFR system as proposed consists of three components: (1) A legacy design intent extractor that generates executable specifications and test vectors of the obsolete part from partial or incomplete legacy data using syntactic and semantic recovery algorithms, (2) An architectural tradeoff environment that selects the right implementation for the replacement parts based on form/fit/functional constraints, and (3) A detailed SW/HW design synthesis component that generates the functional replacement for the obsolete part together with its test vectors. Our approach is further characterized by its board-level replacement methodology, as opposed to traditional chip-by-chip replacement methodologies. A detailed benefit/cost analysis of the proposed approach will be completed in Phase I, together with a comparison to "hardware-in-loop" driven current practice, as applied to weapons systems. The proposed virtual prototyping approach to automated functional replacement (AFR) has immediate applications in the parts obsolescence management problems of the defense and avionics industries (a multi-billion dollar market). As lifecycles of various systems become longer, the problem has become particularly severe resulting in the need for new and powerful technologies as outlined in our technical proposal on this SBIR effort. With decreasing times to market in the commercial world (e.g., 3 months in the telecommunications arena), commercial electronic products require continuous upgrades of systems to include newer technologies and components (thus creating a problem analogous to parts obsolescence in the defense industry). The proposed obsolescence management and upgrade technologies developed as part of this SBIR proposal can be directly applied to commercial electronics products in telecom, embedded computing systems, and information appliance markets - a potential trillion dollar arena. The proposed algorithms, tool suites, and component model libraries that are proposed will facilitate rapid system-level design, upgrade, and test, promising a "model-year" approach to electronics system design, spanning digital, analog, and RF domains. |

| Title: | Nitrogen Charging System for the Advanced Amphibious Assault Vehicle (AAAV) |
| Abstract: | CME will develop an efficient, light weight, high-pressure nitrogen gas charging system that shall be designed for field deployment on the Marine Corps new Advanced Amphibious Assault Vehicle (AAAV). CME will perform trade studies and work with COTS suppliers along with designing custom components to meet the performance, size, weight, and cost objectives. CME's approach and proven experience associated with high-pressure gas systems will facilitate the design of a small lightweight gas charging system that will allow field maintenance operations on the 7000 psi Hydro-pneumatic Suspension Units (HSU's'). The system target weight of 87 pounds is achievable using the AAAV's existing power sources for motivation while still maintaining identified safety margins associated with high- pressure gas systems. CME will apply COTS hardware where applicable to enhance manufacturability, maintainability, and minimal cost impact. CME will apply computer simulations to determine and document overall system performance. During the Option, we will develop final detailed drawing packages in preparation for Phase II. The manufacturer and test of three prototype charging systems will be conducted during Phase II activities. With a final design for a small high-pressure gas charging system, a reliable field-deployable system can be manufactured for the military and commercial markets that need high-pressure gas suspension for field charging of their systems, while also improving the prevention of oxidization/corrosion of internal suspension components. Phase III manufacturing and marketing planning will prepare the nitrogen charging system design for full-scale commercial product launch and entry into related market segments such as auto racing, medium to heavy truck transports, heavy construction equipment, aviation, etc. |

| Title: | Lightweight, 1kW Portable Multi-Fuel Generator (PMFG) |
| Abstract: | The development of a lightweight, portable, multi-fuel generator set with output in the 1 kW range is proposed. The development shall be based on the innovative integration of three enabling technologies that have been realized in recent years. These are: (1) conversion of lightweight, high rpm two-stroke gasoline engines to operate with multi-fuel; (2) high power density, permanent-magnet, axial-gap modular alternator design; and (3) digital, solid-date electronics power conditioning. Each of these technologies has been validated by the proposing team in different arenas to assure the prospect for optimum integration and near-term realization of the overall objective of the project. Phase I effort shall be concerned with the development of concepts and hardware implementation for optimum integration of these technologies leading to a technology feasibility demonstration unit that can meet the weight and output power performance specifications. During the Phase I Option, the design shall be further refined to render the design "Marine Ready" for prototype development under Phase II. It is anticipated that such a lightweight, portable multi-fuel generator (PMFG) unit will also have significant demand in the commercial market for recreational, industrial and home use to meet the multiple objectives of the SBIR program. The realization of small, lightweight, multi-fuel capable generators will significantly enhance the mobility and C4I operational capability of small detachments of Marines on the battlefield. Such units also have demand in the commercial sector for recreational, industrial and home use. |

| Title: | Demonstration of a 40 Pound Miniature Electrical Generator Which Uses a Lightweight, Quiet, Compact, Multi-Fuel Engine |
| Abstract: | Desert Storm indicated that portable lightweight miniature electrical generators are needed for combat field operations. Mainstream has previously developed a JP-8 (multi-fuel) 53 pound 1kW portable diesel electrical generator under a prior Army BAA effort. This Phase I will extend this development effort to demonstrate that based on the results of this earlier hardware development and additional IR&D by Mainstream we feel confident that we can demonstrate a 1 kW unit with a system weight below 40 pounds. This Phase I effort will demonstrate the performance of a prototype system. The proposed effort includes the detailed redesign and fabrication of selected components of Mainstream's existing 53 pound multi-fuel 1 kW diesel generator to provide a demonstration unit which weighs less than 40 pounds. The generator will be configured as a portable unit for easy carrying to the point of use, where it could be set-up to provide continuous, relatively-quiet electrical power. The Phase I will demonstrate the Mainstream's unit meets the Navy's performance, weight, size, fuel economy, reliability, maintainability, and noise requirements. Phase II will include a further refinements and deliverable of prototype units for extensive field tests. This Phase I effort will demonstrate an innovative, compact multi-fuel diesel generator that has tremendous marine, disaster relief, and industrial niche market applications where the safety and stability of diesel fuel over gasoline represents a significant advantage. Mainstream has already committed it own resources and secured a commercialization partner. Our marketing studies have indicated a substantial marine and disaster relief niche market. |

| Title: | A Low-Profile Tagging System for Locating Personnel and Material |
| Abstract: | We propose to develop a remotely deliverable tagging device for both marking and tracking personnel, material, and vehicles. The approach is based on a new radiolocation technique we have developed, which is capable of highly accurate location determination using simple tag electronics. The research goals are to determine how small the device can be made using current electronic and battery technology, to identify delivery techniques capable of deploying the tag from a distance of 50 meters or more, to design low-cost portable base stations for receiving tag signals and determining location, and to study techniques to enhance performance in urban multipath. The system intelligence is contained in low-cost portable receiving/tracking stations that can track the target either stand-alone or collaboratively, as needed. The proposed system will be a major enhancement over our technology developed for applications such as locating patients with Alzheimer's disease and tracking cargo. In previous research the receiver stations were fixed 5 miles apart, and the tag, which did not need to be concealed, was too large for the application proposed here. In Phase II we plan the to implement the miniaturized tag, to refine the delivery concept, and to follow up with field testing with prototype receiving stations. The proposed technology would allow covert tracking and locating of people and valuable material or cargo with high accuracy. It has applications in less-than-lethal warfare and monitoring and locating stolen weapons, tracking cargo and packages, and locating stolen goods. |

| Title: | Resin-Transmitter for Covert, Non-Lethal Tagging |
| Abstract: | Triton Systems responds to the Navy need to covertly and non- lethally tag personnel and/or equipment, at a range of 50 m to 500 m, and to obtain a later return signal at 1 km. The Triton response to this need is to develop its own unique shelf-stable resin-transmitter, using COTS parts. The stable resin contains a micro-transmitter with the required size and range, that will be delivered by a tethered or retarded projectile, allowing the resin-transmitter to separate from the projectile and to be covertly adhered to clothing or equipment as a final stable plastic tag. On the Phase I program, Triton will fabricate the stable resin-transmitter; will demonstrate its separation from a model tethered or retarded projectile, and the formation of a stable adhesive plastic tag. On the Phase I Option, Triton will demonstrate the delivery of a stable tag to clothing and/or equipment at short range, using a simulated tethered projectile traveling at 250 ft/sec, with a return readout of 50 to 100 m. On Phase II, with a ballistics partner, Triton will develop a realistic projectile resin-transmitter delivery system; with separation and delivery of a tag at 50 to 100 m at gun velocity, with a return signal at 1 km. On Phase III, Triton will work with a munitions / arms maker to make a prototype tag delivery system. If the proposed technology is successful, field commanders will have the ability to covertly and non-lethally tag personnel and equipment when conducting military operations in urban terrain (MOUT) and other areas where immediate action is not appropriate. Such a technology also is of intense interest to civilian police organizations worldwide. It would permit them to covertly and non-lethally mark and track vehicles and hostile elements that blend in with the local population of uninvolved citizens. The commercial market for this technology is large. |

| Title: | Handheld Autonomous MEMS Based Navigation/Communication/Tracking System |
| Abstract: | The objective of this SBIR Phase I project is to design, fabricate, and evaluate a low cost, small size, lightweight, handheld, autonomous navigator with wireless communication, map display, and tracking capability. The current position location tracking systems relay on the reception of GPS radio frequency (RF) signals to obtain position information, which prohibits it's use in urbanized terrain environments. Recently, MEMS (MicroElectronicMechanicalSystem) technologies make it possible to fabricate the monolithic integration of MEMS inertial and magnetic sensors with driving, signal pickoff, and signal processing electronics, which offer tremendous cost, size, reliability improvements, compared with conventional inertial sensors. Advanced MMIC technology (Microwave Monolithic IC) can shrink conventional radar into a chip. In this project, the innovative navigator utilizes an American GNC corporation developed commercial product, coremicroTM IMU based on state-of- the-art multiple MEMS sensors and unique ASIC (Application Specific Integrated Circuit) design, tiny magnetic heading sensor, a tiny Doppler radar, and patented filtering technology to achieve high precision navigation accuracy independent of GPS signals for the navigation/communication/tracking system. This Handheld Autonomous MEMS Navigation/Communication/Tracking System will find a large market in the military and civilian sectors. Typical applications will be founded in the areas where GPS signals are not continuously available, such as inside buildings, tunnels, forested areas, urbanized terrain, and high Electronic Counter Measure (ECM) environments. |

| Title: | Multiple-Personnel Tracking System Using Uniquely Coded RF Tags |
| Abstract: | We propose that an RF-based personnel tracking system has significant advantages over presently used or contemplated ultrasonic/GPS systems. The proposed RF tracking system uses a central tracking station and multiple RF receivers to sense signals from personnel mounted transponder tags. The tags respond to uniquely coded probe signals by transmitting a second set of time coded RF signals. Triangulation to the receivers using proprietary signal processing algorithms allows accurate location of the tags in 2 and 3 dimensions. Numerical simulations of the algorithms indicate highly accurate distance measurement capability even under very low signal conditions and in the presence of RF reflective objects. The proposed system can seamlessly be interfaced with existing GPS systems to eliminate the tracking loss problem during building entry/exit. Furthemore, the system could also be extended to km distance scales for full coverage of training ranges. Such extensions could eliminate the need for GPS entirely, leading to a lower system cost. In Phase I we plan to develop and build a simple RF system to demonstrate tracking of at least one person. We will also refine the processor algorithms with a view to extending operating range and maximizing spatial resolution under low signal and multipath conditions. The proposed systems has applicability to fire fighter accountability systems, as well as location and tracking of inventories, equipment, and persons in secure facilities and prisons |

| Abstract: | With recent advances in wearable computing and associated control and display mechanisms, there is significant opportunity to create a more effective operator control system for unmanned ground vehicle (UGV) operations. This Phase I effort proposes to study the UGV control problem, evaluate the advanced technology options for creation of a wearable control system, and design an optimum solution. Cybernet has significant experience to leverage in the development of advanced human computer interfaces, and in the development of portable UGV control systems. Advanced technology options that will be evaluated include: 1) hands-free interface solutions, such as voice recognition, eye tracking, gesture control, etc., 2) miniature force-feedback and other haptic devices, and 3) immersive and head-mounted displays. Selection of the advanced interface technologies will be performed based on satisfaction of the UGV control operation requirements, feasibility of implementation within a wearable computing platform, cost, potential benefit, associated risk, etc. The result of this Phase I effort will be the design of a highly intuitive and effective wearable computer interface for UGV operation, incorporating advanced control and display technologies. The immediate commercialization potential is for a wide range of military and other UGV control applications. The developed wearable operator control interface technology will also have broad reaching commercial potential for many other military and industrial control applications. |

| Abstract: | Significant problems face the USMC as it plans its precision logistics pipelines for Advanced Amphibious Assault Vehicles (AAAV). The USMC now relies on inefficient, manual processes, primitive decision aids, and "time-late" communications in its legacy logistics efforts to support mobile warfighting platforms. An innovative Precision Sea Based Logistics System (PSBLS) - for AAAVs and other USMC mobile units - will address those problems with enhanced logistics velocity, visibility, and variability for Ship to Objective Maneuver. A robust PSBLS solution will embody intelligent agents, capable user interfaces, web-centric applications, plus open-systems interfaces to "operate in such a way that commanders have absolute confidence that required support will be provided when and where it is needed." General James Jones, Commandant ORINCON's team will develop, test, and integrate cost-effective information technologies to automate, monitor, and recommend actions for the USMC precision logistics system. We plan to "instrument the pipeline" from factory to deployed units with automated tracking, cost accounting, prognostic evaluation, and total asset visibility. Our unique technical and operational experience will be leveraged to provide a comprehensive Performance Specification, a Decision Support System design, and a Cost Benefit Analysis for this innovative USMC AAAV logistics program. o The USMC and its AAAV organization will directly benefit from this system's innovative decision support, centralized computers/applications and human-factored total asset visibility (TAV). o Commercial merit of our feasibility study extends to focused logistics systems of all armed services and the DLA. Resultant PSBLS functions can further transition to commercial "just in time" high-volume logistics support systems that are multi-million dollar efforts annually. o Boeing Aircraft Company expressed initial interest in some of our intelligent agents for maintenance support of commercial aircraft systems |

| Title: | Precision Sea-Based Logistics |
| Abstract: | Successful supply-chain management is an essential element in high performance military environments. Rapid delivery of key items to deployed mobile units is a must for military strategists. Effective logistics/supply-chain management allows just-in-time distribution of goods and services. Current technologies are available to evaluate inventory levels across the supply chain. The use of the World Wide Web allows faster flow-through times in supply chain pipelines. Many commercial and military organizations are feeling an urgent need to integrate an extended enterprise logistics system. USMC 's Precision Sea-Based Logistics is a human-factored, computerized system that requires Total Asset Visibility (TAV) of spare parts, issuance of repair notifications, tracking of maintenance history, and cost. USMC plans to deploy a sea-based logistics system. TPI proposes to develop a centralized information logistics system that is based on a fully extended enterprise model. This Precision Sea-Based Logistics (PSL) system will assist in information flow between components of USMC's sea-based physical logistics system. The PSL system will maintain the Total Asset Visibility (TAV) in a centralized database, which will include configuration management and maintenance history and is capable of wire or wireless communication with the mobile vehicles and maintenance facility. TPI believes that the proposed system once implemented would bring US Marines Corps logistics/supply-chain management capabilities into the next decade. It will support the N/MC Intranet structure. USMC is planning to build the N/MCI in the next five years that could be used for global application of the Precision Sea-Based Logistics (PSL) system. Furthermore, the proposed PSL system will assist USMC in achieving its goal of moving the logistics to a sea-based system. There are many direct benefits to USMC and among them are reduced inventory, effective logistics management and on time delivery to the mobile vehicles. General Dynamics Amphibious System (GDAMS) is building Advanced Amphibious Assault Vehicle (AAAV) for the United States Marine Corp. The proposed system can directly be used for AAAV logistics. The PSL system is capable of supporting trucking industry whether or not a truck is near its desired maintenance facility. A mobile truck may be able to quickly report to the base via PSL system its maintenance problems and parts requirements. TPI is planning to approach many Logistics companies once the system is built. Among them are United States Truck Stop Association, United Parcel Services, Federal Express, and others. |

| Title: | Link-16 Enhanced Positional Accuracy for Precision Guidance |
| Abstract: | This SBIR seeks to exploit the inherent synchronization and RELNAV capability of the communication links in network-centric architectures to complement or replace the GPS solutions. Avtec proposes to develop a software solution exploiting the inherent capabilities of Link-16 which is incorporated in most network-centric tactical architectures. Avtec's approach will explore algorithms based on a technique described and patented by the proposed Principal Investigator. Avtec's approach can be applied to any two-way digital link. In Phase I, Avtec will (1) identify optimized Link-16 configuration(s) for synchronization and range measurement using the Round Trip Timing (RTT) feature, and (2) design and evaluate algorithm(s) for merged synchronization and RELNAV using measurements from Link-16 and a representative GPS system. We anticipate that work in this SBIR will lead to future activities related to Link-16 and GPS for network-centric architectures. In addition we see the techniques to be investigated in this SBIR being applied beyond the Link-16 environment. |

| Title: | High Frequency Transmit Mast Clamp Current Probe |
| Abstract: | Fischer Custom Communications, Inc. proposes to determine the types of magnetic core materials required to design and fabricate a current injection transformer capable of exciting various parts of a ships superstructure to act as a transmit antenna in the 2 MHz to 30 MHz frequency range. Conventional high frequency shipboard antennas occupy substantial volume, making them difficult to site on the ship without interfering with ship operations. Conventional anntennas have high maintenance and have a significant and distinct radar cross section. A current injection transformer is virtually maintenance free and would replace existing transmit antennas. By using the existing ship structure as an antenna, the current injection transformer provides HF communication and eliminates adverse operations, maintenance and RCS impact of conventional antennas. In Phase I the appropriate magnetic core materials will be determined and feasibility of the current injection transformer will be demonstrated Conventional high frequency shipboard antennas are difficult to site on the ship without interfering with ship operations, have high maintenance and a significant radar cross section. The transmit mast current probe is virtually maintenance free, has a significantly lower radar cross section and would replace the exisitng transmit antennas. The price of a transmit mast probe will be significantly less than the conventional shipboard HF communication antenna. The annual maintenance cost of the transmit mast probe will be a fraction of the conventional HF transmit antenna. Commercial applications include industrial and recreational maritime communications as well as other industrial and recreational HF communications systems. |

| Title: | Intelligent Jammer Placement Tool |
| Abstract: | The Navy would like to deny GPS-based or other satellite-based navigation to an enemy in times of conflict, and one of the most practical means of doing so is via jamming. However, it is very important to control where the jamming energy is directed so that friendly receivers are minimally affected. This proposal describes Toyon Research's plan to develop a PC-based optimization toolbox to solve the Navy's jammer placement problem and deliver a prototype version in Phase I. Rather than relying on a single optimization algorithm, the toolbox will include several such tools and a flexible means of controlling their application. Built into the toolbox will be smart features to speed up the optimization process and a means of "learning" from the users' experience in different applications. The toolbox will also provide solutions to the problem of mission planning to avoid jamming and will include an easy-to-use graphical user interface. The development will result in a computer tool to simplify the process of deploying jammers which in turn improve the Navy's warfighting capability and increase the fleet's survivability. |

| Title: | Wireless Line-of-Sight Networks for IntraBattlegroup Communications |
| Abstract: | The U.S. Navy is in need of a means for high data rate (HDR) line-of-sight (LOS) communications between its ships, submarines, and shore sites. The total point-to-point intra-battlegroup capacity currently available is less than 268 kbps per ship. This capacity was marginally adequate several years ago, but the increase in traffic load offered by available government off-the-shelf (GOTS) and commercial off-the-shelf (COTS) systems has resulted in requirements for wideband, high spectral efficiency, wireless mobile networks. The Navy is in the process of procuring a software defined radio (SDR), named the Digital Modular Radio (DMR), which addresses issues related to legacy support and hardware development costs. Therefore, an established SDR in the form of DMR addresses the legacy requirements and significantly reduces development costs - the remaining problem is defining a reliable wideband technology. During the HDR LOS BAA, Nova has implemented a spectrally efficient, wideband, wireless waveform that supports heterogeneous mesh networking. The waveform is designed to be resistant to channel impairments commonly encountered in the Navy's signaling environment. The results of this SBIR, titled Wideband IntraBattlegroup Communications (WIC), will add up to 4.608 Mbps of reliable, adaptive multiuser wireless network capacity to each ship within a battlegroup. Both the military and commercial sector have a tremendous demand for more signaling bandwidth. The HDR LOS waveform offers a substantial increase in terrestrial capacity over a diverse set of distances and in the presence of channel impairments such as dynamic multipath. |

| Title: | Wireless Line-of-Sight Networks for IntraBattlegroup Communications |
| Abstract: | Important issues in military networking are more bandwidth, decreased complexity for the operators, increased reliability and the migration to IP-based services. These issues require novel solutions because military tactical networks typically lack centralized infrastructures like cellular networks. In addition, military wireless networks often have lower bandwidths, higher error-ra |
