Title:High Power, High Repetition Rate, Pulsed, Blue Laser for ASW Purposes
Abstract:Yb double clad lasers are the "work horse" of high power systems. By codoping with Sm to quench stimulated emission at 1,070 nm (4 level system), Yb/Sm can be forced to lase efficiently at 980 nm. By further using HOM (Higher Order Mode) fiber design, greater energy storage/length can be achieved, and the shorter length also favors 980 nm radiation. Frequency doubling the q-switched output from such a system with periodically polled lithium niobate, all of the required design criteria desired by the Navy can be met with this new concept.

Title:High Power, High Repetition Rate, Pulsed, Blue Laser for ASW Purposes
Abstract:It is necessary to use blue-green lasers for underwater optical imaging for anti-submarine warfare, location of mines and other tactical underwater targets since the penetration depth for ranging/imaging illumination depends upon the optical attenuation coefficient in various types of waters. The minimum optical attenuation coefficient for ocean waters is found in the blue-green part of the spectrum. Suitable laser transmitter technology needs to be insensitive to environmental conditions as well as compact, lightweight, and efficient. This proposal describes a laser concept for a lightweight, compact, high efficiency, pulsed blue laser transmitter operating in the 470-475 nm range.

Title:High Power, High Repetition Rate, Pulsed, Blue Laser for ASW Purposes
Abstract:A laser will be developed which meets the Navy requirements for airborne anti-submarine warfare missions. These requirements include high repetition rate, short pulse operation at blue wavelengths, and a compact, robust package. The laser will be based on a wavelength shifted, diode pumped alexandrite laser. The wavelength shifting is accomplished by means of Raman and second harmonic conversion. Data are presented for diode pumped alexandrite lasers and Raman conversion from low repetition rate flashlamp pumped alexandrite lasers operating at the required energies. This work builds on Light Age’s demonstrated technologies including its Raman convertors which can handle the 100W power levels required. Phase I will provide studies of the scaling required for diode pumping and a laboratory demonstration of efficient conversion of flashlamp pumped alexandrite output at 753 nm to 486 nm. Phase I goals are the demonstration of the power requirements and efficiency for the conversion of 753 nm light to 486 nm and a design for scaling the diode pumped alexandrite lasers to provide the requisite power. In the Phase II, a prototype system will be demonstrated at 486 nm, with 10 mJ pulse energy at 1000 Hz repetition rate and sub-20-nsec pulsewidth.

Title:High Power, High Repetition Rate, Pulsed, Blue Laser for ASW Purposes
Abstract:The Navy needs high energy short pulsed (1-20ns) pulsed blue lasers for ASW purposes. The current technology lasers are bulky and low efficiency. Princeton Optronics proposes to develop a vertical cavity surface emitting lasers (VCSEL) based high power pulsed blue laser which offers to deliver high energy pulses in a very small size with high efficiency. The potential for such laser has already been demonstrated with high energy pulsed laser output arrays with this technology. In phase I, we plan to demonstrate frequency doubled blue laser with this technology and study its characteristics and means to deliver high power from the array and meet the specifications in the solicitation.

Title:Direct Diode Pumped Blue-Green Laser
Abstract:Present Blue-Green lasers are inefficient (0.5 – 2.0 %) owing to the losses incurred by using multiple/cascaded solid-state and two or more nonlinear optical frequency conversion stages. We propose to develop a simpler approach to a blue-green efficient system: Single-state diode laser pump light in = blue-green laser pulses out To achieve this we will bring together advances in diode lasers/super-luminescent LEDs to provide “in-band” pumping of pulsed and frequency tunable gain media. The candidate systems emerged from a long term internal effort at SARA to identify new systems with output in the blue-green and other regions of the visible spectrum. SARA’s corporate mission is to pursue new technologies and develop highly innovative applications for existing technologies. Within our laser system development projects we focus upon realizing the performance and efficiency inherent in entirely new and previously not well developed laser systems. In addition SARA is well versed in laser detection and tracking systems for applications with technologies including reflected light detection (optical LIDAR type missions), and the challenges facing the applications of lasers to underwater detection and tracking and optical communication in water.

Title:Non-toxic process for depositing highly-dense, corrosion-resistant aluminum on complex geometry components
Abstract:Alameda Applied Sciences Corporation (AASC) proposes dry, non-toxic, plasma-based hybrid energetic ion deposition and implantation process to prepare highly-dense, corrosion-resistant aluminum on complex geometry aircraft components. By replacing electroplated Low Hydrogen Embrittlement cadmium (LHE-Cd), a highly toxic metal and known carcinogen with serious ES&H issues, AASC’s non-toxic process can reduce compliance costs associated with mounting regulatory burdens and reduce the scope of potential legal liabilities faced by today’s Navy. Ion vapor deposition (IVD) and sputtered aluminum, currently used as LHE-Cd replacements, are low energy PVD methods that suffer from columnar microstructures with lower grain boundary density that provide fast diffusion pathways for the anions and cations in corrosion reactions. Burnishing, peening or bead blasting post-processing steps are required to achieve full density, adding cost and reducing throughput. Comparatively, AASC’s hybrid energetic ion deposition and implantation process collapse voids, breaks up columnar microstructures, and produces uniformly dense aluminum layers that will offer superior corrosion performance and avoid post-deposition steps. Further, the use of cathodic arc plasma sources, relative to evaporative (IVD) or sputtering sources, enables much higher rates of deposition.

Title:Ambient Temperature, Solvent-Free Plating of Dense Aluminum Coatings
Abstract:This proposed Small Business Innovative Research (SBIR) Phase I project will demonstrate the feasibility of developing a room-temperature, non-toxic process for the application of protective, highly dense, corrosion-resistant aluminum and anodized aluminum coatings. This process will initially be used for applying aluminum coatings to complex geometry aircraft components. The proposed process will address issues associated with traditional plating methodologies (including operating temperature, organic solvent consumption, hazards, and environmental impact of solvent emissions), resulting in improvements in energy consumption, waste disposal and the reduction/elimination of VOC emissions. A previous project at Eltron successfully demonstrated plating of Al from ionic liquids with toluene co-solvent. The ionic liquid melt consisted of 35% toluene, representing a significant reduction in VOC for the process compared with existing processes. The proposed effort will build on these results, exploring two strategies to eliminate the need for organic co-solvents in this process: investigating other organic chloride salts and applying pulsed deposition techniques.

Title:Non-toxic process for depositing high density, corrosion-resistant aluminum alloys on complex geometry components
Abstract:This SBIR Program is aimed at the development of a non-toxic alternative to cadmium electroplating for corrosion protection of a variety of aerospace components including landing gear, electrical connectors and aluminum structural components. The thermal spray process will be optimized to deposit high density, corrosion resistant aluminum alloys on high strength steel, aluminum and other targeted materials and configured for coating of complex geometry surfaces, including non line of sight (NLS) and other configurations that have traditionally complicated thermal spray processes. The proposed Phase I program will leverage previous work to develop a corrosion protective system for aluminum cladding replacement and focus on applying a similar system for protection of high strength steels and other component materials. A blend of computational and experimental optimization routes will be employed to maximize corrosion protection, as well as extend component surface geometrical capabilities and overall system robustness and portability. Additionally, an important aspect of the Phase I research will be to gain further understanding of the effects of various processing variables as well as the concept capabilities and limitations in order to design a scaled up device for a Phase II program.

Title:Automated Tool for Reporting Aircraft Damage and Queuing and Screening Repair
Abstract:The Navy requires the ability to quickly and accurately measure damage to composite structures. The advent of composite materials has provided improved capabilities for aircraft as well as a host of sea, ground-mobile, and other combat systems. However, while these new materials have significant benefits in terms of reduced weight, higher strength, lower signature, and improved armor performance, the ability to rapidly evaluate and repair damage of these materials requires new tools and methodologies. The historical means of measuring and repairing damage is inadequate for composite structures and components. Identifying the exact location and extent of damage is crucial for determining the type of repair that is suitable. In addition, manual data collection and transfer techniques are prone to the introduction of human errors that further complicate and slow-down the engineering analysis, disposition, and repair process. The proposed approach is to assemble current state-of-the-art data collection hardware with innovative and customized software to provide an integrated data collection and processing system.

Title:Robust, Non-Toxic, Corrosion Inhibitor System
Abstract:Proposed is a robust, non-toxic corrosion inhibitor system consisting of novel, stable colloidal, hybrid polymeric or composite materials that are modified to have functional groups covalently or ionically combined with selected corrosion inhibition groups and are mainly prepared by atom transfer radical polymerization. Chain length and number and type of functional groups can be adjusted. Hydrophobicity and other properties of the polymeric materials can be also modified. These polymers and their mixtures will be designed and formulated into a corrosion inhibiting package (with optimized corrosion inhibitor ratio, concentration and solubility) so that they can be easily applied to metal substrates from water or solvent solutions as pre-treatments, primers or coatings, to provide an innovative, versatile, robust, non-toxic corrosion inhibitor system. This novel inhibitor system can involve more than four-fold synergistic combinations of materials and functions, i.e., (1) polymer network + corrosion inhibitor(s), (2) corrosion inhibitor group A as inorganic oxoanions + group B as rare earth cations + group C as organic anions or compounds, (3) linear (co)polymer structures + core-shell polymer particles, and (4) adherent polymer protective barrier + hydrophobicity (repelling corrosive media), to achieve the desired corrosion inhibiting performances and other hybrid advantages over chromates.

Title:Robust, High-Efficiency, Low-Toxicity Corrosion Inhibitors
Abstract:The actions of effective corrosion inhibitors are tied to their structures and their electronic properties. While there have been many studies of these relationships, there have been few instances of where the design of new corrosion inhibiting molecules resulting from the models. Furthermore, considerations of the toxicities of any new predicted corrosion inhibitors were not built into the modeling scheme. Recently, through a combination of experimental measurements and model building, TDA has identified a small set of molecular descriptors that are highly effective at both prediction of the efficiency of corrosion inhibition and the molecular toxicities. In the Phase I effort, TDA will expands these models using a larger training set and also build structure-property relationships for diffusion through protective coatings. This will then allow us to computationally screen large numbers of molecules so that we can select a few for in-depth evaluation.

Abstract:The available tools to detect skin to core disbonds are both difficult to use and require extensive training. Complex waveforms must often be interpreted. We are proposing a small, portable, low cost ultrasound camera for in-service inspection of honeycomb rotor blades for skin to core disbonds. The basis of our technique is a two dimensional imaging array which generates real time C-scan images of defects in materials. The key advantage of this system is the simplicity of the technique. Therefore, a non-specialized inspector can easily be trained to find small defects in these structures.

Title:Rapid and Conformable Field Repair and Nondestructive Evaluation of Rotor Blade Skins and Honeycomb in Blade Afterbody
Abstract:This proposal describes the development of a novel NDI instrument for rapid and reliable detection of skin to core and skin to honeycomb disbonds in aerospace structures. The proposed field instrument adapts a newly developed fiber-arrayed laser Doppler vibrometer (FA-LDV) to perform true defect detection and imaging as compared to the slow image synthesis employed in conventional point-scanning LDV instruments. This methodology has recently been successfully applied for detection of disbonds and delaminations in metal and composite airframe structures. The proposed effort aims to further extend this technology and design to engineer, assemble and field-test a portable, compact instrument capable of the reliable detection of core-skin disbonds as required by the NAVY. The Phase I study is anticipated to yield an analysis of the instrument configuration, assortment of its critical components, and working envelop estimation. An existing MetroLaser multi-beam LDV instrument will be employed in the Phase I study, to accelerate the process of getting signatures from the specimens with representative defects. These data will be used to design the fiber-optics breadboard system for performing proof-of-concept tests. The Phase I effort will culminate with a preliminary prototype design of an instrument to be developed and field-tested during Phase II.

Title:Rapid and Conformable Field Repair and Nondestructive Evaluation of Rotor Blade Skins and Honeycomb in Blade Afterbody
Abstract:NAVY 07-118 Rapid and Conformable Field Repair and NDE of Rotor Blade Skins and Honeycomb in Blade Afterbody The integration of composite materials into modern military aircraft has provided numerous benefits to the armed forces due to superior strength-to- weight performance and corrosion immunity. However, when compared to their metallic predecessors, composite components present significant challenges in terms of maintenance and repair. The NDI situation has become far more complex with the deployment of composite-based aircraft. Older techniques such as tap testing are slow and are unable to detect all inner-layer and skin to core disbonds. Active thermography has already been proven as a rapid and reliable inspection technique for such applications. In the following Phase I proposal, Thermal Wave Imaging will attempt to distill the advances made in thermographic NDI into an instrument that addresses the cost, size and complexity of the current technology. We will exploit the hardware and signal processing advances made in flash (pulsed) thermography, and apply these to a small, low-cost instrument that is truly handheld and self-contained. The user interface for control and presentation of results will reside on the unit, so that the operator will not interact with a computer.

Title:MENTOR 300B - Spectrographic instrument for analyzing composite surfaces prior to repair
Abstract:Contaminants left on surface of a composite part during repair leads to poor quality bond. Dirt, oil, marking materials, grease, release materials, solvents, other organic and inorganic chemicals, cleaning material residues, biologicals from environment, grit from sanding and metal particles may remain. Menon and Associates is proposing to develop a molecular spin resonance instrument that combines both imaging and spectrographic modules to carry out a broad area scan followed by detailed scan of suspect areas. Both, the surface of part being repaired as well as new materials for repair can be scanned. The goal is to eliminate all non-resin and non-fiber materials upstream prior to and during the repair process. The system, called MENTOR-300B, will be built for complete quality assurance of composite materials spanning the breadth of inspecting the surface to be repaired, prepreg raw materials, its manufacturing process to final layup of composites.

Title:Extremely Low Frequency (ELF) for Anti-Submarine Warfare (ASW)
Abstract:This Small Business Innovation Research Phase I study will briefly survey the various magnetic-field sensors that meet the requirements for being inexpensive yet highly sensitive. The present sensor of choice is a coil with a high-permeability core. This coil will be suspended vertically in the water column. The main challenge will be to reduce motion noise by the suspension system and ancillary motion sensors. Other noise sources (wave, geology, geomagnetic, and flow) will be characterized and quantified; an approach for their reduction will be proposed. An operational analysis will be used to predict the performance of the noise-reduced sensors against various target strength levels in the presence of various noises.

Title:Extremely Low Frequency (ELF) for Anti-Submarine Warfare (ASW)
Abstract:The US Navy has a requirement for an affordable A-sized independent sonobuoy with an Extremely Low Frequency (ELF) magnetic field sensor suitable for operation in both deep and shallow water regions. The 0.5 to 30 Hz ELF band presents an opportunity to detect galvanic current from submarines, especially those which are poorly maintained. ELF sensors have been used in fixed mounted applications, however free floating sonobuoy configurations pose complications due to motion induced noise, control of sensor orientation, and miniaturization. To address the technical challenge of motion induced noise we propose to develop our ELF sensor concept teamed with UnderSea Sensor Systems, Inc. which senses horizontal flow and repositions the drogue and ELF sensing element to a stagnation point. Whole field magnetometers will eliminate the need for precise orientation of the sensors. Additionally we will use of multiple ELF sensing elements to correlate and discriminate far-field geomagnetic noise.

Title:Extremely Low Frequency (ELF) for Anti-Submarine Warfare (ASW)
Abstract:An inexpensive sonobuoy to detect the Extremely Low Frequency magnetic field emissions from a submarine would complement the Navy’s acoustic detection capability. Under this program, QUASAR Federal Systems (QFS) together with Applied Signal Technology and Prof. John Hildebrand of the Scripps Institution of Oceanography will bring to bear demonstrated expertise in magnetic induction sensors and sensor systems to build a cost-effective underwater B-field sensing system. The system will be based on the QFS 18” long induction sensor, reconfigured to fit in an A-sized sonobuoy. The proposed system will be capable of detecting and processing ELF magnetic field signals in the ocean with sufficient sensitivity for Anti-Submarine Warfare (ASW). The proposed system will fit into an A-size sonobuoy, have a sensitivity of 0.3 – 0.5 pT/rtHz at 1Hz, reject vibration and motion induced noise below 0.5 Hz, incorporate other motion noise cancellation capabilities, have integrated data acquisition, processing and telemetry, and be low cost enough to make a disposable system feasible. In Phase I, we will establish the feasibility of using a magnetic induction sensor for this application, and in the Option period, we will provide an outline design for a free floating sonobuoy prototype.

Abstract:During the Phase I Base Effort, an omni-directional hydrophone will be designed and tested for prospective use in a ULF sonobuoy application. The design will be based on a sensor that was previously developed for an unrelated ULF application, but will generally fit within design envelope of the AN/SSQ-53F calibrated omni. The Base Effort will also entail evaluation of three different hydromechanical suspension systems that are adaptations of the suspension system employed by the AN/SSQ-53F DIFAR sonobuoy. The overall sonobuoy system architecture will also be developed during the Base Effort and will largely be driven by the hydrophone and hydromechanical suspension system design. The Phase I Option will entail an in situ evaluation of the hydrophone and hydromechanical suspension system at ultra-low frequencies. A majority of the experiments will be performed at the Lapel Test Facility operated by USSI.

Title:Ultra Low Frequency (ULF) Sonobuoy
Abstract:In order to counter the quiet modern submarine threat, sensor systems require innovative concepts and sensor developments that exploit the acoustic environment. There is a low acoustic ambient noise window the Ultra Low Frequency (ULF) band, in the 0.01 Hz to 0.1 Hz range, which has not been adequately explored with regard to tactical underwater acoustics. This acoustic band is attractive for passive detection, since propagation is good at these frequencies and target signals would be impossible to mask or suppress in the low ocean ambient noise in this band. This effort is to develop an air-deployed in- water acoustic sensor capable of Ultra Low Frequency performance in the ocean environment. The feasibility of developing a ULF acoustic sensor on a suspension that isolates it from ocean wave-induced motion will be demonstrated. Laboratory models will be fabricated to measure the appropriate parameters to assess ULF performance in the ocean. A means to discriminate self-noise from ambient noise will also be devised. The results from the Phase I effort will be used to develop and demonstrate an A-size over- the-side model in Phase II to show that the sensor meets performance requirements and measures acoustic ambient noise rather than sensor self-noise.

Title:Ultra Low Frequency (ULF) Sonobuoy
Abstract:The US Navy has a requirement for an affordable A-sized sonobuoy with an Ultra Low Frequency (ULF) acoustic sensor. The ULF acoustic band presents an opportunity to detect emissions from submarines, assuming they exist, would be particularly hard for the target platforms to suppress. ULF detection in a free floating sonobuoy configuration poses complications due to motion and flow induced noise. To address the technical challenge of flow induced noise we will develop our ULF sensor concept teamed with UnderSea Sensor Systems, Inc. based on a neutrally buoyant swallow float design. The feasibility study will evaluate two development paths using varying levels of automation. The operator-in-the-loop option would deploy a drifting neutrally buoyant sensor subassembly at the desired sensing depth and employ an acoustic or wired datalink to a floating sonobuoy RF transmitter. The second automated option would package the entire sonobuoy payload as a neutrally buoyant float which will stabilize at the desired sensing depth, and given a target detection of sufficient confidence would employ a pop-up RF transmitter to pass the detection and data report. We will determine the optimum frequency band to exploit target signatures with minimal noise interference, and then determine the appropriate acoustic sensor design.

Title:Method and Device for In-Service Repair of Magnesium, Aluminum and High-Strength Steel
Abstract:The Purpose of this proposal is to develop a portable process to repair precision aircraft components. Typically, they are composed of magnesium, aluminum, or high-strength steel base alloy, and may have a protective coating, such as cadmium or aluminum. These components damaged in the field must be removed from the aircraft to complete typical repairs. In addition, protective coatings, especially sacrificial coatings, have no viable, on-aircraft repair processes. Currently, Electroplated Hard Chromium (EHC) and Low Embrittlement Cadmium (LHE-Cd) are being used to repair worn and damaged components for a variety of applications. However, since it is a known carcinogen and produces waste that is detrimental to the environment, their use and disposal are strictly regulated. Demeton has extensive experience in repairs of high-strength steel, including 4340 alloy (260-280 ksi), with Demeton Detonation Spray Process (DDSP). Demeton, through past experience, has identified that DDSP is the best alternative to repair base alloys and protective coatings in order to restore material properties as close to original as possible with current requirements in the field. Since DDSP does not require high pressure gas or a special high pressure cooling system, the portability of the system is feasible for in-field repair works.

Title:Portable Kinetic Metallization Process and Device for In-Service Repair of Protective Coatings on Magnesium, Aluminum and High- Strength Steels
Abstract:The low temperature Kinetic Metallization technology offers a portable process and device for in-service repair of metallic protective coatings on magnesium, aluminum, and high-strength steel based alloy components used on various aircraft. Damage to protective coatings on these aircraft alloy components include abrasion and cuts. Repairs frequently require removal from the aircraft at the Navy Aviation Depots and airfields or temporary repairs with environmentally hazardous brush plating processes. In-service repairs of damaged metallic coatings including cadmium and IVD-Al would reduce the maintenance cost and allow the aircraft to remain in operational service for longer periods before overhaul. The object of the Phase I research is to develop Kinetic Metallization as a portable process for repairing metallic protective coatings on magnesium, aluminum, and high-strength steel base alloys for aircraft components. Using a handheld Kinetic Metallization gun, repair coatings will be tested and evaluated as a viable process for in-service repair of damaged protective coatings on aircraft components.

Title:Method and Device for In-Service Repair of Magnesium, Aluminum and High-Strength Steel
Abstract:The objective of this proposal is to develop a methodology for using the Cold Spray Process for in-service repair of magnesium, aluminum and high-strength steel. The process will focus on the development of corrosion resistant coatings and provide improved corrosion resistance with a minimal effect on the base materials properties. The performance of two portable systems will be evaluated. One system is a commercially available system that uses air and nitrogen as the carrier gas and the other system is a system that uses helium as the carrier gas. Evaluation criteria will include coating properties (density, adhesion, strength, and corrosion resistance), easy of use, cost and portability. The efforts will address coatings for magnesium, aluminum and high strength steels. The results of this effort will be used to establish the performance of the available portable systems and to define the requirements for a portable system that will meet the in-service requirements. The end result will be an environmentally friendly, economical, portable system that can be used to apply coatings for in-service repair of magnesium, aluminum and high strength steels used is aircraft.

Title:Environmentally Friendly Removal of Fluid Contamination from Composite Aircraft Structure
Abstract:The US Navy is seeking an improved cleaner that can remove hydraulic fluid from aircraft composite materials. The cleaner must be compatible with these materials, and must not introduce any significant environmental, health or safety hazards into the workplace. Materials compatibility is the toughest criteria for a candidate cleaner to meet, because any degradation to structural integrity or reliability is totally unacceptable. Current cleaners, promoted as safe and environmentally friendly have been found to be deleterious to the performance of the composite materials. METSS proposes to develop and test new, environmentally benign formulations that are compatible with the materials of construction using a proven approach to cost-effective materials development. METSS will draw on existing materials, working directly with industry participants to select the best materials for product formulation. This ensures a non-biased approach to achieving the program objectives and opens up the opportunity of creating customized formulations that can be designed to directly address performance requirements. This effort will include optimizing the performance of the cleaner to meet and exceed the performance of the currently used cleaners while considering environmental impact, safety, and toxicity. A prototype cleaner will be formulated and demonstrated to be compatible with the aircraft composites.

Title:Environmentally Friendly Removal of Fluid Contamination from Composite Aircraft Structure
Abstract:Aerospace composite structures (e.g., carbon/epoxy) have enjoyed increasing use in aircraft manufacture over the last few decades. With strength-to-weight ratios superior to metal, their use has facilitated large decreases in aircraft weight. Composite structures often become contaminated by various aircraft fluids during maintenance or repair. Hydraulic fluid is the most wide spread contaminate encountered. Contaminated structures must be cleaned efficiently to maintain the strength of these high performance materials. Hydraulic fluid contamination, left unattended or poorly cleaned, can cause composite weakness due to plasticization, delamination, and disbanding. The solvent of choice for cleaning composite structures has historically been hexane, which efficiently removes hydraulic fluid contamination without adversely affecting the composites. However, environmental regulations have forced the Navy to use methylisobutylketone (MIBK) for cleaning instead. Unfortunately, MIBK is inefficient for this purpose, and contaminated parts often must be sent to a controlled facility for cleaning with hexane after several failed attempts using MIBK. This results in extra costs in terms of both time and money. In response to this problem, TRI/Austin is proposing to develop a new solvent based on non-toxic, zero-VOC, and non-HAP materials that can be used without regulation to efficiently decontaminate composite structures. The solvents utilized will be both environmentally and personnel friendly, and will have no regulations for shipping and handling, making them easily accessible to the Navy. TRI/Austin will examine both single solvents and multi-solvent formulations for this purpose. Both organic and aqueous systems will be tested. Composite samples will be subjected to contamination, cleaned, and the efficacy of the solvent will be determined by the retention of composite physical properties. The resulting solvent formulation will save the Navy time and money, and will also be a step towards a healthier environment.

Title:Conformable, Compact Isolation System for Repairs
Abstract:CRG proposes to demonstrate feasibility of an environmental boundary system to reduce the time and cost of performing composite repair. This technology will also increase the quality of the repair for composite parts on platforms, such as the V22, due to the ability to keep the repair area contained. CRG has a unique concept that will accomplish the goal of environmental containment yet still allow easy repair. The concept is comprised of a lightweight truss structure that provides support to a clear plastic film. The trusses may be a semi-flexible, lightweight plastic, or even shape memory polymer (SMP), which will provide great benefit in stowing the system. The system will include hand ports that allow passage of hands and materials through the containment system while sealing automatically without any powered activation device. This design will prevent dirt or dust to pass through while the repair is ongoing. The hand ports also allow the repair technician to use any type of gloves, improving the dexterity and cleanliness of the repair environment. This system will be self-supporting and provides a unique way of transferring materials without using the traditional glove box approach. It will be stowable, lightweight, and cost effective.

Title:Self Assembling Environmental Shield
Abstract:To address the U.S. Navy need for an environmental shield to protect repair areas from debris and contamination, especially in austere environments, Physical Optics Corporation (POC) proposes to develop a new POsitive Pressure repair SHIELD (POP-SHIELD) as an environmental shield that provides protection during in-field repairs of composite structures on aircraft, vehicles, boats, and ships. The heat resistant shield can be quickly installed and assembled with the use of a compressed air line. Redundant, independently actuated suction cups firmly anchor POP-SHIELD to surfaces without unreliable consumables such as tape or adhesive. The innovation in POP-SHIELD will enable the device to be quickly and securely assembled over a work area, using only air power. In Phase I POC will demonstrate the feasibility of POP-SHIELD by developing a proof of concept prototype, which will show its ability to meet the Navy’s needs. In Phase II we plan to develop a pre-production prototype, and demonstrate that it can protect work areas in real work scenarios.

Title:Novel Magnesium Based Nano Composites
Abstract:Developing low cost, lightweight materials with high stiffness, that are environmentally safe, low risk/liability, and corrosion resistant is extremely important for the Department of Defense in the current climate of reduced spending and desire for increased performance. Reducing program life cycle costs for new materials in a program is also important, but additional desirable benefits for a new material include; reduction in component and system weight, providing multi-function capability, and limiting the use of potentially hazardous materials. This APS Phase I NAVY SBIR program plans to demonstrate these desirable characteristics in proven materials. The APS demonstrated nano composites provide many solutions to decreasing a systems mass, while providing multi-functional capability (corrosion resistance, modulus, low cost, etc…) within system components. APS has assembled a world-class team that is well versed in design, materials testing and manufacturing for aerospace structures to successfully complete this Phase I program.

Title:Innovative Surface Modification for Aluminum, Magnesium and High Strength Steel Alloys to Enhance Corrosion Resistance
Abstract:This proposal seeks innovative solutions to address the Navy’s needs to extend life and durability of its aircraft. It is proposed to apply surface treatment strategies for two important classes of materials: Custom 465 Stainless, and CSS 42L carburizing stainless steel. The former is a highly corrosion resistant high-strength precipitation hardening material that, nevertheless, will require surface hardening to enhance wear resistance. It is proposed to accomplish this through mechanical treatments such as peening before aging, and, low-temperature carburizing. The latter material is also a high-strength stainless steel that is intended explicitly for carburizing applications, and exhibits corrosion resistance suitable for applications such as the wing-fold transmission (WFT) system. We request funding to conduct a preliminary analysis of the mechanical and corrosion characteristics of these two materials (Phase-I), and optimize the processing of them necessary for the WFT application (Phase-II). The goal is to identify materials and processes leading to a WFT component that meets mechanical requirements and does not require a separate scheme for corrosion control. The identification of the process parameters will lead to the development of multiscale models for strengthening in steels due to combined effects of surface hardening and heat treatment with higher corrosion resistance.

Title:Innovative Surface Modification for High Strength Steel Alloys to Enhance Corrosion Resistance
Abstract:The Navy experiences costly corrosion maintenance problems and component failure resulting from corrosion. An innovative approach utilizing surface modification methods is needed to reduce processing and life cycle costs while providing a high component surface hardness with improved corrosion and wear resistance for Navy aircraft components such as drive mechanisms. The Phase I effort will involve development and demonstration of the feasibility of a cost efficient low temperature carburization surface modification process applicable to high strength martenstic stainless steels, such as Pyrowear 675, which is used in components such as in the weapons bay door drive system, in the Joint Strike Fighter. The use of the low temperature carburizing process will result in lower cost, increased corrosion resistant and wear resistant components for the JSF. Phase I will also involve laboratory testing to establish wear resistance and static strength levels and will also involve trade-off studies comparing low temperature carburizing of various martensitic and precipitation hardening stainless steel alloys. An Option Phase will involve optimization of the low temperature carburizing process for Pyrowear 675 for use in JSF components and laboratory testing to determine the fatigue, fracture toughness and corrosion resistance of low temperature carburized Pyrowear 675 alloy.

Title:Innovative Surface Modification for Aluminum, Magnesium and High Strength Steel Alloys to Enhance Corrosion Resistance
Abstract:7xxx series aluminum alloys are widely used for structural components of aircraft such as wing spars due to their high specific strength. Unfortunately, tempering most 7xxx series alloys to peak strength results in susceptibility to stress corrosion cracking (SCC). Despite utilizing the best available surface treatments, SCC results in unscheduled maintainence of naval aircraft. QuesTek Innovations LLC, a leader in the emerging field of computational materials design, is uniquely suited to design an SCC-resistant, high- strength aluminum alloy for the aerospace industry. QuesTek has experience commerciallizing high-performance stainless and gear steel alloys, and QuesTek has developed extensive mechanistic process – structure and structure – property models specific to 7xxx series alloys. These models include custom thermodynamic and kinetic databases, well-calibrated microstructural evolution models utilizing PrecipiCalc software, and a validated, physics-based strength model. The overall goal of this SBIR program is to design and develop an advanced, high-strength aluminum alloy with improved SCC resistance compared to commercially available Al alloys. To demonstrate the feasibility applying Materials by Design® approach during Phase I, QuesTek plans to develop a qualitative model for SCC of aluminum alloys; design model alloys to achieve the 7075-T6 strength with maximum SCC-resistance; and produce and characterize these model alloy designs.

Title:Low Temperature Gaseous Nitriding of 4340 Steel for Increased Corrosion Resistance
Abstract:Corrosion-related maintenance of metal alloy components such as hydraulic wing and blade fold actuation systems for carrier-based aircraft and rotary gear assemblies costs the Navy approximately $1 billion per year. Innovative and low-cost surface modifications that do not compromise mechanical properties are needed to improve the corrosion resistance of the alloys. Current surface treatment technologies offer limited effectiveness in long-term use for steel alloys. These techniques include the application of hard chromium coatings, which have toxicity issues. Nitriding and/or carburizing techniques are other traditional methods used to harden steel alloy surfaces and improve corrosion resistance. One shortcoming of these methods is that the high processing temperatures required risk degrading the mechanical properties of the steel alloy. Recently investigated methods of nitriding iron at low temperatures have demonstrated that iron can be coated with a thin layer of nickel (<100 nm) and that an iron nitride layer can be formed below the nickel coating when exposed to an ammonia atmosphere at temperatures as low as 225°C. The catalytic nickel coating affects the preferential formation of the desired iron nitride compound instead of the iron oxide (i.e., corrosion). The iron nitride layer is hard, non-porous, and chemically stable at temperatures below 400°C. This process has not yet been used commercially. In this project, Ultramet will deposit a thin (<100 nm) layer of nickel on iron and 4340 steel using chemical vapor deposition technology, which does not rely on conventional thermal activation, thereby minimizing the deposition temperature. The resulting surfaces will be nitrided in an ammonia atmosphere at 325°C and lower. The viability of chemical vapor deposition for production of a hard, wear-resistant surface on these materials will be assessed, and the ability to protect them against corrosion and retain their mechanical properties will be evaluated. Chemical vapor deposition is the best alternative for protecting steel surfaces because it is the only process that can treat steel at low temperature without altering the mechanical properties of steel.

Title:Ultra-Wideband (UWB) Imaging Array Surveillance Sensor
Abstract:The goal is to develop and demonstrate an UWB imaging surveillance sensor array capable of detecting intrusion of man or machine in to secure (exclusion) zones. The asynchronous nature of modern war exacerbates the protection needs of critical infrastructure: airfields, waterfronts, and other facilities. Developing a multi-lateral UWB sensor fence-line has immediate application for force and infrastructure protection both domestically and abroad Sperient proposes a multilateral time-of-flight impulse radio-radar system to enhance detection accuracy, eliminate false alarms, and operate on the lowest power with the stealthiest signal. The multi-lateral approach is superior to conventional sensors because scaling information about the target may be derived from multiple sensors. The approach includes utilizing Sperient’s (patent pending) impulse communication technology to detect time-of-flight (ToF). When a target passes between the radio transmitter and receiver, the difference in ToF is more reliably detected than in conventional systems. Radios used as described constitute an ultra-high resolution sensor. Additionally, detection range goes as 1/R2 rather than 1/R4-yielding much longer detection ranges. Since detection depends on time-of-flight (TOF) rather than amplitude, the sensors will yield better resolution and noise immunity. Lastly, multiple sensors enable better target estimation and may include: target size, gait, number of legs, and potentially heart and breathing rates.

If this can be determined, then the next step will be to produce a proof of concept unit, then demonstrate and characterize the performance in a multitude of real life scenarios. If successful, this effort will result in the production of a new, robust, high performance, low cost and unique perimeter security system.

The project will be successful if 1) the detection, false alarm and classification thresholds can be met for the target environments and 2) the hardware is producible and has a cost advantage over conventional microwave, IR sensor techniques and other sensors approaches.

Title:Tool for Recovery, Maintenance and Repair of US Navy Cable Systems
Abstract:The U.S. Navy has special requirements for recovery, maintenance and repair of seafloor cable systems. The Navy frequently makes repairs to cable systems damaged by seafloor hazards by dragging a grapnel hook near the vicinity of the break. The process of recovering the cable to make the repairs is time-consuming and without knowing the exact location of the seafloor cable, can lead to further damage to the cable by dragging it along the seafloor and fouling it with other submarine cables or seafloor hazards. Makai proposes to develop an advanced computer tool for the planning, simulation, and real-time control during recovery and re-laying of the Navy’s cable systems. Running on standard PC’s and in a GIS environment, the proposed tool will accurately model cable retrieval operations and create office generated sail plans that can be used during at-sea recovery operations. All information relative to the recovery operations will be maintained in a GIS database easily accessible during at-sea operations. The proposed software tool will allow the Navy to retrieve cables with lower values of seabed tension, allowing for faster recoveries and minimizing cable dragging on the seafloor, which ultimately will result more efficient and in safer recoveries.

SiC devices with an 8 kV voltage rating and 300°C junction temperature significantly reduce the size, weight, and footprint of the bridge and heat sink. Furthermore, SiC thyristors and AC-link enable a high operating frequency, which minimizes the size and weight of passive components. During Phase I we will model the converter’s operation over a wide range of conditions and use the results to complete a detailed design of the bridge, heat sink, inductor, and capacitor subassemblies, including component selection, cooling, assembly considerations, and voltage isolation. In the Phase I Option, we will design the enclosure and component layout and obtain quotes from contract manufacturers for each subassembly. In Phase II we will build a system demonstrating the power density and performance of the converter and optimized subassemblies. GHO Ventures has expressed interest in our Phase III manufacturing effort.

Title:VOST Flow Control Device
Abstract:An innovative flow control device will be built and tested. Based on cryogenically proven, highly efficient Venturi-Offset Technology (VOST) developed for NASA, it has no stem- actuator, few moving parts, and an overall cylindrical shape. Consistently demonstrating breakthroughs in flow control, VOST technology provides precise linear flow control across its entire dynamic range, holds position without power, and requires remarkably low actuation energy. This project will demonstrate the viability of using VOST for autonomous, bi-directional, self-powered, low-pressure drop isolation valves for shipboard use.

Title:Innovative Flow Control Devices for Shipboard Fluid System Rupture Isolation
Abstract:Current shipboard emergency flow control devices for fluid systems use either pneumatic power or electric motors to close valves when a rupture is detected. These systems are dependent on the availability of the electric power or low pressure air systems. In a casualty situation, these support systems could also be lost and the flow control devices would not operate as intended, placing the ship in even greater extremis. SEA CORP proposes to use its extensive experience in the use of commercially available automotive airbag inflators to develop an innovative application of this existing technology to provide the pneumatic energy to autonomously close fluid system valves when a rupture is detected. The inflator(s) would be individually mounted to each valve and controlled by local circuitry that would normally use available ship’s electrical power, but would have a small (D-cell size) battery backup in case normal power is lost. Algorithms will be developed, or adapted from current “smart valve” systems, to ensure that only those valves required to secure the rupture would close, allowing use of the remainder of the affected system. This technology is easily adaptable to commercial applications such as shipping, oil, and chemical facilities, especially in remote locations.

Title:Hand Deployed Situational Awarness Sensor for Shipboard Damage Control
Abstract:Current methods of damage control assessment onboard US Navy ships subject personnel to hazardous environments. These methods are labor intensive and dangerous. Our proposal outlines the initial design and architecture of a ruggedized multi-sensing wireless device and the remote monitor to which it interfaces. The sensing device we propose is self-orienting, shock resistant, waterproof, buoyant, capable of withstanding fire, explosions, toxic gases, and able to transmit high-bandwidth data, including video, wirelessly to the remote monitor with a range beyond 70 feet. 3eTI has significant experience with wireless mesh equipment and wireless sensor technology, and has deployed wireless equipment to U.S. Navy surface vessels and on U.S. Navy bases. All 3eTI products meet U.S. Navy requirements, including the vast array of wireless certification and accreditation requirements. Due to our significant experience with wireless sensor systems and remote monitoring for the U.S. Navy specifically, 3eTI is well-positioned to develop a working product that meets all of the requirements in this SBIR topic

Title:Hand Deployed Situational Awarness Sensor for Shipboard Damage Control
Abstract:Damage sustained on board a US Naval vessel is a serious situation. Rapid situational assessment of a damaged compartment by a rugged, hand-deployed, situational sensor would be advantageous in coordinating a response, mitigating additional damage to the ship and crew, and preserving the ship’s mission. Such a device must be able to withstand shock, heat, flooding, and other hazardous environmental conditions. A concept and implementation plan for a rugged, modularized, configurable environmental sensor is discussed in this proposal. Key features proposed include multiple camera systems for visual feedback, on-board data processing, and wireless connectivity. In addition to providing rapid response to the US Navy, it is envisioned that this device has broader applications to federal, state, and municipal hazardous materials response departments.

Title:Increasing Automation in the Shipbuilding Production Process
Abstract:As stated in this SBIR solicitation, “The Navy's Program Executive Office for Ships is leveraging the National Research Program (NSRP) to effect change across… surface shipbuilding…to adapt and implement "World Class" commercial best manufacturing practices.” Shipyard Process technology is identified as an area of high relative benefit within the NSRP Strategic Investment Plan. The overall objective of this proposal is to develop an automated shipbuilding structure manufacturing process. The NSRP SIP identifies structure as a high importance area within shipyard process technologies. Benefits will be realized in the application of multi-technology lean manufacturing cells, which will reduce the work done in situ in the main shipbuilding bay and in single process work centers. These cells will contain general purpose robots as well as other CNC machines. They will use such technologies as tool changing to minimize handling of the large assemblies typical of ship structure. The process will be designed to reduce distortion, eliminate fitting, and achieve high process capability. Typical technologies within the cell would include cutting, welding, assembly, coating, and measurement. This project will address specific NSRP objectives, namely to increase work accomplished by robotics and to improve fabrication of internal decks, longitudinal bulkheads, and stiffeners.

Title:Operational and Process Management Improvement through Implementation of In-process Manufacturing Wireless Asset Tracking
Abstract:Impact Technologies, LLC, with support from Northrop Grumman Ship Systems, proposes to develop and demonstrate a Wireless Mobile Asset Tracking (WMAT) system with integrated reasoning algorithms to monitor and locate in-process manufactured parts. Implementation will hinge on development of both hardware and software solutions tailored to the ship construction and repair industry. The hardware will be designed to withstand the riggers of a shipyard environment fusing both global and local position tracking technologies into a single, cost-effective, integrated package. Embedded reasoners will be employed within the software to determine the location of in-process materials and identify the most probable locations of those assets that have been mishandled and cannot be found. An electronic visualization will identify those areas in the shipyard to search for missing materials. Data garnered from the tracking system will facilitate improved production planning by having the ability to continuously track and monitor the status of materials throughout the entire shipbuilding process; thereby, creating a more efficient, agile manufacturing climate. Trending of historical data will enable study of workflow patterns to improve overall operational efficiencies in shipbuilding processes.

Title:Demonstration of a Practical Low-Energy-Consumption Dehumidification Device for Shipping Containers
Abstract:The thrust of this proposal is to use Mainstream’s proposed concept for a VC-QuaDD dehumidifier to demonstrate an innovative low-power compact dehumidification design that can be powered from alternative energy power sources including solar, wind, and even internal battery power, as well as ship-board or vehicle power. The system can also obtain power from energy scavenging devices. This proposal contains detailed calculations to support the design chosen, as well as a preliminary design of the complete first-generation prototype unit that will be experimentally demonstrated in Phase I. The proposed configuration can be used on existing 20' ISO containers, as well as smaller TriCon and QuadCon containers. This Phase I effort will prove the technical feasibility of the approach using a full-scale first-prototype configuration. Reliability, durability, and low cost will be demonstrated, as well as compatibility with existing ISO containers. The Phase I Option includes re-design (as needed), fabrication of a second-generation prototype, performance testing on a 20' ISO container, and extensive life testing (to demonstrate the ruggedness and reliability) of this compact patent-pending design. The proposal contains a commercialization plan for the shipping, marine, and industrial markets. This product fits well into Mainstream’s evolving commercial products for the shipping industry.

Title:Quasi Dynamic Dehumidification (QuaDD)
Abstract:This proposal addresses the need for a robust moisture-removal system for containers used for shipment and storage of high-value equipment such as aircraft engines. Current desiccant-based systems incur high inspection and servicing costs, and may still allow humidity-related damage to occur. TIAX proposes to develop a passive, self-regenerating desiccant (SRD) ventilation system to work in tandem with the current desiccant device. This system will remove moisture from air entering the container, thus greatly extending the life of the existing desiccant, and will passively self-regenerate, with no need for an external power source. The use of a desiccant-coated matrix as the moisture removal material both aids in desiccant regeneration and assures low humidity for in-flowing air even when the desiccant is close to saturated. In this work, TIAX will partner with Airxchange, Inc. the leading OEM supplier of air-to-air enthalpy recovery heat exchangers and manufacturer of desiccant-coated matrix material. Airxchange will supply both materials and expertise in support of the project. Using matrix materials currently available from Airxchange, an SRD system designed for a standard 20’ ISO container and extreme, “worst case” conditions is predicted by TIAX to supply very low-humidity in-flow air, and occupy only 0.015% of the container volume.

Abstract:The proposed study considers the translation between speech vocoders of both wave form and parametric types. Transcoding and tandem methods of translation are proposed for the various codec pairs. The special case of multi-user conferencing scenarious with a variety of different codecs is considered. A methodology for the translation between different speech compression methods is developed. This methodology is used in the development and implementation of a parametric codec to parametric codectranslation.The minimization of degredation to the speech communication is considered with special emphasis placed on intelligibility. At the same time an effort is made to minimize the complexity of the translation. Specific subjective test methodologies are proposed to evaluate the degredation.

Title:Multi-standard Vocoder Translation (MuVT) Software for JTRS Secure VoIP Application
Abstract:Mayflower Communications proposes the Multi-standard Vocoder Translation (MuVT, pronounce move it) Framework and Software Suite to meet the Navy objectives, namely, develop “minimum loss” vocoder translations among a pre-determined set of vocoders and qualify the translation software for speech quality, processor requirements and JTRS SCA compliance. The proposed MuVT Framework is a mathematical foundation and an associated Software Suite that accomplishes the process of translation between multiple codecs. The MuVT Framework/Software includes a set-up for speech quality assessment (in a laboratory setting) using the ITU P.862 PESQ and an implementation/development strategy to demonstrate the MuVT technology on JTRS compliant hardware platforms, and eventual incorporation into the JTRS Enterprise Business model to insure software interoperability among all potential JTRS vendors. The proposed MuVT technology leverages Mayflower’s expertise in secure VoIP communications and builds on previous Mayflower R&D programs. The MuVT technology, when proven feasible in the Phase I study for the Navy application, has enormous potential for military and commercial applications. Mayflower will develop a cost effective MuVT prototype software suite in Phase I and II, and ensure its commercialization in Phase III and beyond.

Title:Human Performance Modeling in the Naval Capabilities Development Process
Abstract:As the Department of Defense continues to emphasize the Joint Capabilities Integration and Development System for evaluating material and non-material solutions, the importance of robust modeling tools continues to increase. The objective of this Phase I SBIR is to provide US Navy analysts with more comprehensive insight into the human-to- machine interface by developing a C4 behavior model. The model will support the assessment of multi-step decisions associated with command and control systems to include attributes such as process time, data uncertainty, human error and decision dependencies. The resulting performance metrics will be incorporated into a decision support environment to facilitate the evaluation of concept cost versus benefit. The data fusion framework linking the behavior model metrics and integrating multiple data sources will be built on an infrastructure initiated by investments from the Missile Defense, Air Force and Navy offices to provide robust decision traceability during acquisition decisions. The Phase I program will solidify the Phase II requirements by having selected Navy analysts and OPNAV stakeholders interact with the proof-of-concept graphical user interface (GUI) and supporting database structure to conduct actual human performance assessments. The Phase II program will fully develop a prototype tool and validate its operation and use concept.

Title:Human Performance Modeling in the Naval Capabilities Development Process
Abstract:The overall objective of this work is to create a model of the decision process in C4I that will integrate human decision making analyses into NCDP assessment processes In Phase I, a model of the human decision process will be developed, and algorithms required to use that model to evaluate human performance, will be specified. This proposal integrates and extends three tested methodologies for defining performance and estimating the effect of performance-shaping factors on mission performance. The first methodology (Link and Node Analysis) identifies where human activity occurs in a mission thread (the Nodes) and how information is distributed between those nodes (the Links). The second methodology, a model of the human decision-making process, specifies what happens within a node and identifies factors that effect human performance. The third methodology, model-based simulation, allows us to use the extensive existing literature on human performance capabilities to estimate the effect of those performance-shaping factors on process outcomes. The final product of this Phase I research will be a descriptive model of the human-decision making process that can be used to drive a simulation of overall system performance and to assess the impact of various performance-shaping factors on that performance.

Title:Artifact Assessment Tool Suite Infrastructure (AATSI)
Abstract:Using our 50+ person-years of experience with testing, XML processing, and Eclipse for DoD, we aim to largely automate compliance testing and catalog artifacts by providing a framework to integrate disparate compliance tools, for JTRS-TD to reduce time/effort by at least 30% over the tested product’s lifecycle. Our architecture for Artifact Assessment Tool Suite Infrastructure (AATSI) supports compliance test initiation, execution, result evaluation/storage, and queries to generate reports. Through one common open- standards based infrastructure into which ‘best-of-breed’ tools can be integrated as web services, we future-proof AATSI to accommodate today and tomorrow’s platforms for real-time and conventional systems. The architecture accommodates compliance and quality assessment tools, requirements tools, configuration management systems, report generators, log file analysis tools, Eclipse TPTP, and more. Our architecture represents meta-data and optionally artifacts in an XML canonical format for tool interoperability, replacing proprietary solutions. We permit automated and customized tests, latter using business processes compatible with service-oriented architecture. We propose a design, evaluation, and implementation roadmap. Innovations include XML-compliant Artifact Meta Language, promoting document standards either at XML schema or document interchange level; rule-driven components for extensibility; Orchestration Service for concurrent request execution; experience-based cognitive learning; and visualization via a compliance measure dashboard.

Title:Artifact Assessment Tool Suite Infrastructure (AATSI)
Abstract:Tracking the quality, completeness, standards adherence and consistency of radio software from initial requirements, coding, testing, all the way through to production is a complex and error-prone task involving a myriad of people, processes, and technologies. The various groups responsible and involved in the critical radio software engineering phase such as development, configuration management, testers, release, users, etc. are often separated by organizational boundaries, disconnected toolsets, or possibly even vast geographic locations. Automation and integration of such efforts is key to solving this issue, to include integration of relevant processes, tools, analysis capabilities, artifact management and other related efforts. An excellent opportunity exists to solve this problem of disconnected efforts by implementing a program such as AATSI. The goal for AATSI is to support compliance and quality assessment analysis of digital artifacts produced for all phases of code intensive product development, particularly code intended for embedded real-time systems. Additionally, this effort will provide opportunities to extend these capabilities to provide historical reporting and tracking for the life cycle of the products. It will allow various teams to work together seamlessly within the same infrastructure, supporting the efficient and successful delivery of radio software.

Title:Extremely Wideband Antenna for Airborne and Land Mobile Communications Systems
Abstract:Joint Forces interoperability systems such as the Joint Tactical Radio System (JTRS) require antennas that are extremely broadband. Some of the joint systems operate in HF/VHF/UHF and L-Bands and require antennas that can operate from 2-2000 MHz. Current conventional antennas do not perform adequately as communications antennas. This problem is further exasperated when the antennas are installed on a fixed/rotary wing aircraft or land mobile vehicle and do not perform due to size and weight limitations as well as detuning because of the vehicle. FIRST RF is qualified to develop an innovative approach to antenna design and integration on airborne and land mobile platforms for extremely wideband communications systems. FIRST RF is proposing to integrate up to five unique antenna technologies into the proposed system. This broad approach early in the Phase I effort is proposed in order to generate the best solution for US Army. These technologies are aimed at improving gain, bandwidth, and size. FIRST RF engineers have designed, tested, simulated, and validated critical components of the technologies of the system. These data allow FIRST RF to make preliminary predictions of installed performance. Prototypes developed in preparation for this proposal are available for immediate testing and human engineering.

Abstract:TSC proposes to estimate and display local propagation conditions (refractivity) using selected shipboard communication signals in real-time, i.e. estimate Refractivity-From- Communications (RFCOM). The proposed approach frames the problem as a non-linear least squares estimation problem involving measured communication signal level profiles, range dependent parameterized refractivity profiles and a parabolic wave equation solution model. Phase I demonstrates feasibility by implementing candidate techniques against simulated data and validating them using directly measured propagation data available from NSWCDD. Phase II will develop prototype code for a real time implementation and validate the code against field test data. Phase III will integrate this new capability into onboard communications systems and the Navy Integrated Tactical Environmental Sub-System (NITES). Outputs of Phase I are: a detailed algorithm description; MATLAB code; a measured signal requirements specification detailing the requirements placed on the communication systems in order to produce the require measurements; and feasibility assessments validating the method for selected cases and assessing potential performance in practical scenarios. Phase II outputs are prototype software and broad validation results based on field demonstration. Phase III outputs are requirements definition documentation, software design/development, system integration, and test efforts for integrating with NITES.

Title:Widely Distributed Optical Clock
Abstract:To address the Navy need to distribute a pulse-based clock signal with low jitter (<2%) at high speed (>20 GHz), Physical Optics Corporation (POC) proposes to develop a new Widely Distributed Optical Clock (W-DOC) system. This proposed W-DOC is based on hybrid integration of state-of-the-art optoelectronic components and an optical waveguide platform. This novel system integration of low-noise components and packaging and phase-lock loops to suppress jitter to its quantum limit at this elevated speed, will provide a reliable clock system for the Navy. The electrical clocking will be converted, transmitted, and widely distributed in the optical domain over a long distance and recovered where the signal is needed. An innovative hybrid conversion between return- to-zero and non-return-to-zero logic supports unprecedented performance by optimizing between optoelectronic and electrical components. The new all-passive optoelectronic assembly not only reduces cost but also offers flexibility in future maintenance and upgrades because of its modular design. In Phase I POC will demonstrate the feasibility of the W-DOC system by designing, fabricating, and testing a prototype system and establishing a simulation model. In Phase II, POC plans to continue optimizing the technology and advancing the technical readiness level.

Title:Assessing the Impact of GPS Degradation Using Campaign-level Warfare Modeling
Abstract:With increased reliance on GPS for navigation, targeting, and guidance, the threat of jamming and signal spoofing is significant. These threats create a greater risk in mission success and potentially increased casualties in U.S. and Allied force operations. GPS jamming can cause receivers to operate with a large navigation error, or with a failure to acquire the GPS signal altogether. GPS spoofing can potentially cause a receiver to report incorrect or false navigational data. Under this Phase I funding, MAXIM Systems will review engineering and campaign level DoD modeling platforms, define requirements for more granular GPS degradation models and their integration with established platforms, and build a proof of concept. Focused on realistic warfare scenarios, the goal of this work is to effectively bridge the gap between high fidelity engineering based GPS models and overarching campaign level models. Key to this process will be defining an automated data sharing design allowing the models to be executed quickly on a large scale to facilitate their use in mission planning and execution, with accurate representations of degradation in different types of unit level equipment and terrain environments.

Title:Cognitive Radio Capability for Software Defined Radios
Abstract:Shared Spectrum Company (SSC) and Space Coast Communication Systems, Inc build on its work on the DARPA XG program to incorporate adaptive cognitive radio capability into the Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA). SSC performs feasibility studies to determine which capabilities may be realized through cognitive radio techniques, and to quantify their expected benefits. In support of these studies, SSC delivers a design paper showing how a cognitive radio module fits into and works within the framework of the JTRS SCA and its Application Programming Interface (API). SSC’s approach is twofold: (1) to design a system capable of autonomously configuring a network by optimizing multiple physical layer parameters (frequency, data rate, modulation, etc.); and (2) to implement proven dynamic spectrum access (DSA) technology within the JTRS SCA. DSA brings a secure spectrum policy administration system together with real-time spectrum sensing to enable rapid, autonomous frequency selection. This application of DSA will start the process to transition XG technology into the JTRS waveform library, thus enabling efficient transition of the XG techniques to all JTRS radios.

Title:Cognitive Radio Capability for Software Defined Radios
Abstract:A Cognitive Radio (CR) is a radio in which communication systems are aware of their environment and internal state and can make decisions about their radio operating behavior based on that information and predefined objectives. Space Coast Communication Systems, Inc. and sub-contractor GDC4S are well established in the fields of Software-Defined Radio, Cognitive Radio and JTRS. We propose a review of the current state of the art in CR and seek to identify a few candidate technologies that both offer value and are sufficiently mature for migration to the JTRS enterprise. Our proposed effort includes definition of new JTRS API’s and extensions to existing JTRS API’s in order to allow access to these new cognitive capabilities. Our experience with the JTRS HMS program gives us confidence that this platform and other platforms across the enterprise are both capable of hosting and benefiting from some of the CR technologies. Our final proposed focus is on the design of a spectrum sensing capability – a requirement for CR - and the design of two physical layer approaches that can immediately tap into the benefits of Dynamic Spectrum Access, one of the more gainful aspects of CR technology.

Title:Cognitive Radio Capability for Software Defined Radios
Abstract:Cognitive Radio (CR) technology can improve management of the RF environment by providing better visibility of the RF environment, facilitating spectral congestion and interference detection, and allowing automatic reconfiguration to mitigate the effects of interfering signals. A CR is defined as a system that senses and is aware of its operational environment and can dynamically, autonomously, and intelligently adjust its radio operating parameters. A CR embodies three concepts: 1. Characterization of its operating environment. 2. Real-time adaptability of its operational parameters. 3. Capability to remember and learn from past experiences. Employing these concepts inherent in CR is imperative to the future of both DOD and commercial wireless communications and efficient utilization of our RF spectrum. Next generation communications will be based on Software-Defined Radio (SDR) technology and will employ techniques to monitor and modify in real time its critical parameters to adapt to a changing operating environment. These critical parameters will include frequency agility, modulation, and transmit power control. In addition, next generation communication systems will be required to incorporate technologies to provide a high level of network security drawing from all available means - hardware, software, computer, or even waveform signatures. These enhancements can be achieved via Cognitive Radio technologies.

Title:Small Buoy for Energy Harvesting
Abstract:A “Small Buoy for Energy Harvesting” has applications for use on current and future buoy systems used by the submarine fleet of the United States Navy. This work proposes to meet the requirements by converting mechanical wave energy to electrical energy using a generation system housed in a spar buoy. The energy extraction method will work with the natural orientation and motion of the buoy. Accumulated energy can be used to power a variety of systems including surveillance and communications and will greatly extend the operational capabilities of remote and independent marine based platforms.

Title:Parasitic Power Pack (P3)
Abstract:Parasitic Power Pack (P3) is a modular power generation device that will fit into a 3-inch diameter free floating buoy on the ocean surface. P3 will not interfere with the antenna on the upper portion of the buoy and will not occupy more than 20 inches in length producing a steady power output of at least 4 milliwatts with a capacity to store at least 60 joules of energy. Of the different energy harvesting concepts for powering wireless sensors we use the incessant oscillations of the ocean waves under which the buoy is excited. Unlike regular wave energy devices that are tuned to ocean waves, we have a platform whose dimensions are preset for a specific purpose. Our intent in this effort is to design this platform which is not tethered to the ocean bottom, but a robust maintenance free design that can survive the shock loads that will be imposed on delivery and one that will survive other operating conditions that it could be subjected to. We will demonstrate the effectiveness of our technology through mechanical and electrical modeling.

Title:Wave Energy Harvesting Buoy for Communications at Speed and Depth and Distributed Sensor Networks
Abstract:Mikros Systems Corporation addresses the need for current and future buoy systems used by the United States Navy’s submarine fleet to increase situational awareness and battle group integration by enabling Communications at Speed and Depth (CSD) and through Distributed Sensor Networks (DSN). Mikros proposes a system solution consisting of small buoys that harvest energy from both ocean waves and sunlight. The proposed system utilizes wave energy harvesting technology currently under development by Ocean Power Technologies, Inc. (OPT), coupled with a small array of solar cells. This dual-technology approach should provide full communications capability at nearly all ocean locations in the world (i.e. at high latitude locations where waves are energetic and at near equatorial locations where they are not). The Mikros team’s solution, based on a unique wave energy harvesting technology, addresses the issues associated with CSD and DSN while exceeding the power generation requirements set forth in the solicitation. It will enable at least an order of magnitude higher communications bandwidth and payload longevity than the minimum set forth in the solicitation, and the increased power generation capability may lead to other novel, currently unidentified buoy applications.

Title:Vibro-Electric Converter (VEC)
Abstract:To address this U.S. Navy need for an energy harvesting technology for a 3 in. diameter buoy that floats free on the ocean surface and needs extended mission time, Physical Optics Corporation (POC) proposes to develop the new Vibro-Electric Converter (VEC) technology, based on alternating induced electric charges in oscillating variable capacitors. POC’s proposed VEC harvests the energy of ocean waves and converts it to a charge in a battery without the need for any external source of charge or electric voltage. The innovative VEC design will result in a powerful energy source, producing over 7.5 mW per module, while being lightweight (<2 lb.) and compact (about 400 cu. cm) due to POC’s proprietary technology for the permanent prepolarization of electrodes with a very high charge density. Because of the contactless displacement of a single lightweight moving part, VEC will work longer than any rechargeable battery. In Phase I POC will design, build, evaluate, and demonstrate the proof-of-concept VEC prototype, and in Phase II, develop, build, and demonstrate performance of VEC prototype in a real environment with a small buoy.

Title:QuickCode Automatic Code and Test Generation Suite for Real-Time Embedded Systems
Abstract:Sophisticated real-time embedded systems pose a unique challenge to system developers, especially if the system includes a complex mixture of software components and special-purpose hardware, and when the development occurs cooperatively across organizations. QuickFlex, Inc. proposes QuickCode, a flexible, extensible development environment capable of automatically generating standards-compliant software and hardware source code as well as test and validation capabilities for real-time embedded systems. The system will rely upon the Architectural Analysis and Design Language (AADL), a precise formal notation for representing the interface relationships among both the software and the hardware modules that compose a real-time system. Through the use of AADL's property notation a Software Communications Architecture (SCA) virtual machine is implemented as a system simulation model. The simulation model will present a complete implementation of the SCA operating environment and will provide an API for target-specific hardware interfaces outside the scope of the SCA. The team's effort will leverage the Open Source AADL Tool Environment (OSATE), which is in turn built upon the widely used Eclipse tool environment. The tool will generate C, C++, AADL, CORBA IDL, VHDL, SystemC, and Verilog.

Title:Business Process Transformation Tool for Rapid Reconfiguration of Navy Systems
Abstract:Using our 50+ person-years of experience with business process (BP) modeling, BPEL, SOA, and HCI design, we propose a BP Transformation Tool for warfighters and other SMEs that will cut time to create BPs up to 80% and training time to learn tool as much as 40-fold, compared to industry-leading BP design studio tools from IBM. We will extend our LiquidApps tools suite, used today by primes to rapidly design HCIs for Fleet, to create a higher abstraction level for SMEs to rapidly design mission-oriented BPs into capability packs or FnEPs, and guide and analyze on-the-fly reconfiguration to meet changing mission objectives by exploiting disparate and geographically dispersed services. We can dynamically align data models and messages from net-centric services via fuzzy logic, inference, and cognitive learning to overcome information disparities, unlike today’s world of static, not reconfigurable, data. Additionally, a reusable BP and abstract services catalog allows the system to learn over time to reduce work for SMEs in future. Our reuse component helps expose web services for stovepiped but time-proven C2/C4I systems (e.g., GCCS-M, NTCSS, JPMIS, CLIP). Our techniques support composing then orchestrating efficient mission-oriented applications that infuse real-time data but meet system performance demands and QoS guarantees.

Title:Business Process Transformation Tool for Rapid Reconfiguration of Navy Systems
Abstract:Most current Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) systems exist in stovepipe environments that do not lend themselves to evolving network centric paradigms. This creates barriers to information sharing, hinders the improvement of situational awareness, and denies progress towards better speed and quality of decisions. Lack of a rapid business process modeling capability impedes the data coordination needed to better exploit sequential and parallel processes at the system level. The absence of reconfigurable systems and data models prevents the decoupling of complex processes into simpler problems to solve. Today, system reconfiguration would require modifying the systems and writing costly integration software. The time required to modify the system is usually measured in years or months at best. What is needed is a Business Process Transformation Tool for Rapid Reconfiguration of Navy Systems which will support FORCEnet Engagement Pack (FNEP) creation and dynamic data and service modifications on the fly given changing mission requirements. The tool set will perform rapid reconfiguration of Navy systems across the distributed enterprise with regard to mission objectives, while using business process models in a service oriented paradigm.

Abstract:Research Proposed: Research is proposed to investigate the feasibility of adapting an innovative rules-based, Business Process Management technology that could lead to rapid, near real time reconfiguration with reliable connectivity. Problem/Opportunity: Navy C4I capabilities are fairly stove-piped in nature and require the integration of complex services across many operating domains. Present solutions for these information disparities are not reconfigurable by design. Existing technology combined with innovative research can solve such information disparities over evolving net-centric environments as well as guide this reconfiguration and transformation on the fly. Plan/Process Outline: Identify and document the range of systems, data models, platforms and sensors utilized in the FORCEnet engagement pack concept. Combine SOA, Business Process Management and Business Rules Management Systems technological concepts in a unified architecture enabling operational agility while addressing the reconfigurement of processes and business rules across distributed enterprises. Benefits: This technology should be one of the solutions to FORCEnet's most significant goals by providing each decision maker the ability to depict situational information in a tailorable, user-defined format. This automated business rules approach supports the complex man-machine interaction resulting in higher quality decisions made quicker with greater speed and accuracy.

Title:Microwave switches for cryogenically cooled RF receivers
Abstract:We propose to develop and build very low loss microwave switches for use in cryogenic, high vacuum environment. The resulting switches will outperform current room temperature switches while operating at cryogenic temperatures under high vacuum and will be able to handle high power levels up to 33dBm as well as endure thousands of temperature cycles and tens of millions of switching cycles or better at speeds of at least 10 microseconds. First we will develop target switch specifications. Using these specifications, we will design a switch for cryogenic operation. We will outline the cost/benefit trade-offs for commercial-off-the-shelf components (COTS) versus specialized designs. Finally, we will prove the feasibility of COTS components, either as the approach or as a baseline for comparison. In the Phase I option, we would reoptimize the design given the results of the measurements in Phase I. These technologies will push the state of the art and the challenge areas for the Phase II demonstration will be identified. A number of significant technology advances in RF design and cryopackaging must be achieved to accomplish the goals of the program.

Title:Dynamic Interference Canceller for High Dynamic Range Analog to Digital Converter (ADC)
Abstract:A longstanding problem with wideband radio receivers for sensitive naval applications (such as Signals Intelligence or SIGINT) is the high level of radio frequency (RF) interference including those from co-located RF transmitters. This proposal addresses the critical interference problem with an improved architecture that permits wideband cancellation of undesired high power signals, thereby providing better utilization of the dynamic range. In order to accomplish frequency-independent interference cancellation, a copy of interference signal (called the cancellation signal) with precise amplitude and true-time delay matching is subtracted from the receive signal. The cancellation signal is digitally controlled with adaptively programmable gain and delay components thereby facilitating high precision interference cancellation. The enabling component of the new architecture is a flux subtractor that performs accurate subtraction of one or more unwanted signals before the front-end of the receiver, and thus enhances its operation in a high EMI environment. The new scheme is particularly well-suited for a digital-RF transceiver architecture, featuring direct conversion of RF signals to digital. The adaptive interference canceller takes full advantage of high-speed digital cross-correlators, look- up tables, true-time delay elements, digital amplifiers, and ADCs.

Title:Blind Adaptive Signal Cancellation for Wide Dynamic Range A/D Converter
Abstract:The very high-resolution V Corp analog-to-digital converter with Adaptive Signal Cancellation (ASC) uses a parallel array of high-speed, high-resolution analog-to-digital converters (ADCs) with blind adaptive interstage matching to successively cancel large signals from the analog input and thereby allow very wide dynamic range digitization of the remaining lower level signals. Conventional pipelined subranging ADC architectures without V Corp’s proprietary ASC signal processing suffer from transfer function discontinuities due to gain, phase, and DC-offset mismatches between the multiple ADCs. These discontinuities introduce nonlinear distortion that severely limits the usable Spurious Free Dynamic Range (SFDR). The ADCs must be matched extremely accurately to enable high-resolution performance, which is very difficult to accomplish because the mismatches are a function of input frequency, amplitude, sample rate, and even small temperature changes. The key to the efficacy of this Adaptive Signal Cancellation architecture is the ability for the processing to calibrate itself in the background to insure optimal dynamic range by cancelling large signals. The architecture (including multiple ADCs, DACs, support electronics and adaptive processing) can be implemented in a compact, low-power custom ASIC or a printed-circuit board with discrete components and an FPGA. Note that this architecture does not use digital post-processing to notch filter out large signals. The ADC architecture itself inherently cancels the large signals by using V Corp’s proprietary signal processing to assure interstage matching. During Phase I, V Corp will demonstrate the architecture with detailed simulations over a wide range of operating and environmental conditions. During Phase II, a real-time implementation of the A/D converter system will be implemented and tested.

Abstract:We will develop a basic technology concept and prove concept feasability using modeling and simulation of an RFDS for the extended frequency band (2-18 GHz) utilizing both CLIC and cryogenic technologies. Using a combination of cryogenic filters, cryogenic low-noise amplifiers, and cryogenic conventional components, EMI tolerance and EMI rejection can be introduced into the RF front end without significantly increasing the noise figure of the system or impacting proper demodulation of the received waveform. First we will develop target RFDS specifications. Using these specifications, we will perform a link analysis/system design to determine the critical components in the chain from both a performance and technical challenge perspective. We will also outline the complete system architecture. Finally, we will explore the technologies to design any components identified as key challenging components. Successful completion of this effort will form a solid foundation for building and testing an engineering prototype in Phase II.

Title:Packaging and signal transfer hardware for cryogenically cooled RF receivers
Abstract:The electronic benefits of using cryogenically cooled and/or superconducting electronics comes from higher potential speeds, higher signal to noise and lower thermal noise. Use of cryogenically cooled and/or superconducting electronics for shipboard, airborne, and long life stationary applications prohibits the use of liquid cryogens. There is no standardized cryogenics platform available for use at this time that employs closed-cycle (cryogen free) refrigeration. In Phase I, we propose to design and (in Phase II) construct a Rack Mounted Cryogenic Platform that will satisfy the need for packaging of signal transfer hardware for cryogenically cooled RF receivers and other superconducting electronics. We will establish thermal criteria that will allow “hot swapping” of key elements of an instrumentation package having superconducting and/or cryogenically cooled circuit elements. This will lead to the design of a complete system that will have access to the cryogenically cooled circuit elements by way of an air lock system and standardized chip carriers. The chip carriers will demonstrate thermal grounding and electrically connected functions compatible with hot swapping capability. This includes cryocooler, cryostat, airlock/actuator, chip manipulator, superconducting-to-normal low loss leads, and vacuum electrical feedthroughs.

Abstract:Improved dissemination of software, updates, messages, and data in tactical networks require new and adaptive systems to improve war fighter’s decision making abilities, performance and systems readiness. Degradation of services across platforms needs to be avoided while reducing update times for C4I applications, techniques and technologies in tactical networks including remote nodes with limited and intermittent communications. The Agent based Viral Object Caching and Dissemination Overlay (AVOCADO) system provides a novel dissemination system for existing networks (such as the GCCS-M in Tactical networks) based on an overlay data caching system using agents, data objects, and automation scripts. Existing update management systems send files from a base node to each other node, causing countless redundant data paths. AVOCADO will stop redundant data transfer and wasted bandwidth while guaranteeing delivery of data, software and updates to all needed nodes.

Title:A Tactical Bulk Data Distribution Service (TBDDS) For Caching Software Updates Over a Wde Area Network
Abstract:Navy software applications and systems such as GCCS-M are installed on hundreds of ships, many of which are positioned away from major shore facilities during periods of deployment. There is a need for technology that can provide dependable delivery of software update packages and other large non-time-critical data objects, all while making the most efficient use of constrained resources and capabilities found in tactical networks. Phase I research results will be applied to developing an architectural design for a Tactical Bulk Data Distribution Service (TBDDS) that will ultimately be suitable for use in the dissemination of large packages of bulk non-time-critical data to shipboard systems located anywhere in the world. Phase I research activities will initially focus on three primary areas: (1) technologies for data transport that are resilient to periodic and/or unpredictable interruptions in network functionality, (2) technologies for semi-persistent staging of data at intermediate nodes to optimize efficient use of limited network capabilities, and (3) technologies for resource efficient multi-hop routing of data through sparse-connection tactical networks. A proof-of-concept demonstration of the TBDDS architectural design will be performed through network simulation and analysis efforts at the conclusion of the Phase I effort.

Abstract:For this Phase I program, Spectra Research will leverage its recent accomplishments in advanced antenna designs (and those of its research partner GTRI) to investigate the application of fragmented aperture and fragmented volume technologies in concert with metamaterial based EBG substrates to develop a reconfigurable broadband (UHF to L- band) antenna. The work will take advantage of current FDTD algorithms and broad experience in EBG materials. Innovative approaches that improve overall antenna performance while minimizing antenna profile are desired solutions for all volumetrically restricted platforms. The Spectra Research team proposes an innovative approach to accomplishing the program objectives by employing advances in fragmented aperture antenna designs, and metamaterials EBG research, in concert with the extensive Spectra Research capability in designing specialized antennas, to develop solutions for a unique UHF through L-band common aperture, reconfigurable antenna. Both Cartesian and cylindrical FDTD simulations will provide a set of design rules that then may be used to modify analytical approximations.

Title:Runtime Integration of NETWARS with Warfare Assessment Models - (MP 54-07)
Abstract:Under the Navy’s Programming, Planning and Budgeting System (PPBS), OPNAV conducts simulation-based assessments to provide traceability from systems characteristics and performance (C&P) data at the Program Executive Offices (PEOs) and Program Management Offices (PMWs) to warfighting effects computed by engineering, mission, and campaign level models. Accurate modeling and simulation of Naval and Joint communications systems is a key aspect of this PPBS process. The current state of communications modeling is to run engineering level simulations in NETWARS and then pass static data tables as input to multi-mission models such as the Naval Simulation System (NSS). This methodology neglects feedback paths that exist within the communications architecture and does not meet the government-mandated level of fidelity for the PPBS process. To address this issue Metron will extend a High Level Architecture (HLA) federation between NSS and NETWARS that Metron investigated in 2003/4. In order to make this federation practical for use in the short analysis timelines required by the PPBS process Metron will dramatically reduce scenario construction times by implementing an NSS to NETWARS two-way scenario transfer. Efforts will reduce the federation runtime by identifying and focusing on key scenario timeslices to construct dynamic communications data tables.

Abstract:Intermodulation refers to a wide-spread problem in RF power amplifiers. When an amplifier amplifies multiple frequency-separated signals simultaneously, or one signal with more than one frequency content, it also mixes different frequency contents of these signals such that two frequency contents in become four out. These added frequency contents are referred to as intermodulation products, and are undesirable. In this proposal GIRD Systems will perform a thorough trade study, algorithm development, analysis, simulation, and testing. Based on customer input and system requirements, an innovative mitigation method and algorithm will be developed and finalized for further prototype development and demonstration in Phase II.

This Phase I effort will characterize the performance of a PA with and without these IMP reduction techniques for 2,4, or 8 simultaneous signals, culminating in a recommended best-value approach for Phase II implementation.

Title:Efficient Linear Broadband RF Power Amplifier Technology (2007029)
Abstract:This abstract is prepared in response to DoD SBIR Solicitation 2007-2, Topic No. NAVY 07-155. The new generation of tactical communication system will have capabilities to adapt its power amplifier operating mode to specific operational needs for multiples of functions linking multiples of platforms The objective of the proposed program is to establish a design baseline for linear power amplifiers operating multiple functions over the frequency band of 2 MHz to 2 GHz. The proposed amplifier will be of a MMIC design fabricated by the novel technology of wide bandgap devices. In addition to the power output design goal of up to 200 watts, the Phase 1 effort will also include analysis of non- linear property of the amplifier and applicable linearization processes. Hittite will then identify the optimum process for MMIC implementation of the amplifier and provide modeling results of the core technology demonstrating the RF, DC, and thermal characteristics of the amplifier. Along with these simulations and analyses, a roadmap showing the insertion of the technology into the transmitter shall be delivered as a Phase II Plan. As an option, a baseline GaN MMIC shall be designed and prepped for processing.

Title:GaN HEMTs for Broadband RF Power Amplifier Technology
Abstract:GaN FETs are capable of very high power levels relative to Si or GaAs technologies. This high power density leads to very broadband capability as needed for the 2MHz-2GHz JTRS radio program. Nitronex has commercialized AlGaN/GaN HEMTs on silicon substrates. As such, reliable devices and accurate device models are available for sub- 4GHz operation in class AB. During this Phase I, we will demonstrate the feasiblity of a PA based on our GaN FET technology that meets all the JTRS requiements. We will investigate PA designs for this applciation using our current generation discrete devices, our next generation high frequency capable GaN FET devices (that can be used in Class D topology) and our GaN MMICs for this applications.

Title:Modeling and Simulation for Information Operations Training
Abstract:Today's information warriors are not sufficiently trained to deal effectively with the threats posed by our potential enemies and terrorists to disrupt or destroy our computer networks, or steal or delete our valuable and sensitive information stored in these networks. Team DigiFlight has personnel who are skilled in the required technologies, and can develop training scenarios that will be useful in the classroom. Additionally, we have already developed tools that have been demonstrated to be effective in several phases of information operations, and will be useful for demonstration in the classroom. Further, we propose to develop a training "package" that will use modeling and simulation techniques to maximize the effectiveness of this training to the IO practitioner.

Title:IO-Train™: Information Operations Training Using Modeling and Simulation
Abstract:Information operations (IO) training is a challenging problem because of the abstract nature of IO tasks. Today, modeling and simulation, augmented with appropriate visualization and animation techniques, is seen as a promising approach to convey abstract IO concepts. Phase I of this project is concerned with researching communications and process models as well as simulation frameworks (e.g., NETWARS/OPNET) to provide fundamental insights into the information space associated with IO. Specifically, Phase I will develop effective visualization and animation techniques to convey abstract concepts in communications and mission planning for the warfighter. The relationship between measures of system performance, geometry of distributed assets, channel effects, and measures of mission effectiveness will be demonstrated through a concept-based prototype of scenario-based modeling and simulation. The results of the research will be analyzed to determine the content of training layers beyond system operations. Specifically, commercial advances in network communications planning will be levered along with the use of animation to train features of complex communications and protocols. The development approach will include a plan to integrate commercial modeling capabilities to both extend and influence operations.

Title:Modeling and Simulation for Information Operations Training (MP 51-07)
Abstract:Metron, Inc., proposes a unique solution for combining visualization, mission-level modeling, and automatic collection of mission/campaign success metrics, with the goal of improving training of Information Operations (IO) practitioners. The first part of the effort will focus on which elements of the five core capabilities of Information Operations (IO) are amenable to training via modeling and simulation (MODSIM). During Phase 1, Metron will focus on these capabilities and proposes to federate the NSS model with other well- established engineering models of utility to the IO community, with the goal of allowing IO practitioners at different levels to visually trace actions up to mission/campaign outcomes or down to physics/engineering first principles. The IEEE 1516 and IEEE 1484 standards will be used as guidelines for the approach. As part of this effort, Metron will develop key IO training scenarios, focusing on the effects-based operations desired by the IO community. Metron will map measures of effectiveness (MOE) and measures of performance (MOP) to these mission-campaign objectives, and tie the MOE/MOP back to higher-fidelity models in use by the IO practitioner. A mock prototype will be developed that includes a set of test scenarios which demonstrate the training potential.

Title:Geoacoustic Sea Bottom Characterization Using Passive, Cost-Effective Sensors
Abstract:Alaska Native Technologies (ANT) and Johns Hopkins University-Applied Physics Lab (JHU-APL) have teamed to present an innovative, solution to the acoustic inversion sensor problem by combining a new, cost effective, high gain, broadband array (JHU, sponsored by ONR Code 32) with a new UUV (glider, ANT, sponsored by ONR Code 321) designed to operate in littoral areas that has extensive onboard processing capability and communications, JHU has been developing a new array composed of inexpensive PVDF wire. The compact array has been successfully tested and would fit on the nose of a new glider. Littoral Glider (LG) can carry the array and process the data in situ and report results during its weeks-long mission.

Title:Geoacoustic Sea Bottom Characterization Using Passive, Cost-Effective Sensors
Abstract:The Navy can gain a significant operational advantage by knowing the ocean’s seabed properties. It is well known that the seabed type can have an enormous impact on sound propagation and therefore effects detection and classification of underwater targets. Seabed properties often are the unknown wild-card in predicting how ASW and MIW sonar systems will perform. Estimating the seabed properties around the world has proven to be an extremely difficult task with today’s technology. In this proposal, a novel method is presented for passively estimating seabed properties with a cost-effective, autonomous sensor. This new approach can provide a way to vastly increase the coverage of seabed maps at a small fraction of the expense using current technology. Rather than using a sound projector (which typically requires a research or T-AGS ship), we exploit the ambient noise that occurs naturally from wind and breaking waves on the sea-surface. This greatly simplifies the measurements and allows for the development of an autonomous sensor from a buoy or autonomous vehicle (i.e., glider or UUV) for seabed geoacoustic characterization. Although using ambient noise for such an important characterization may seem a bit far-fetched the results are surprisingly good.
