| 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. |

| 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. |

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. |

| Abstract: | N07-118 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. |

| 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. |

| 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. |

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. |

| 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. |

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.

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: | 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: | 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 225øC. 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 400øC. 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 325øC 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. |

| Abstract: | Flexible ultrasonic arrays can readily detect delaminations and disbonds in composites. Recent experience has shown that thermal damage in composites may also be characterized with ultrasound. This SBIR project will investigate flexible arrays for implementing this advanced ultrasonic technique.

| Title: | Ultra-Portable, Low-cost, Nondestrutive Evaluation Technologies for Rapid Damage Assessment in Epoxy-based Composite Materials |
| Abstract: | In-theater operations of US Navy/Marine Corps aircraft can result in operational damage that requires rapid detection and repair so as not to interrupt mission operations. Multiple Nondestructive Inspection (NDI) technologies are available for in-depth analysis of suspected damage zones at higher-level maintenance activities. Unfortunately, the only inspection methods available for rapid on-site damage detection at the squadron level are visual and tap testing. Texas Research Institute Austin (TRI/Austin), in collaboration with Dr. Mel Siegel from Carnegie Mellon University and Physical Acoustics, proposes to develop a portable inspection system for detecting damage in composites. The TRI team will construct a breadboard instrument that will perform a controlled impact tap test and utilize both accelerometer and microphone data to assess damage in composite materials. In the Phase I work, the design for the composite inspection system will be completed and the instrument will be built and tested to ensure system functionality. |

| 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. |

| Title: | Ultra-Wideband (UWB) Imaging Array Surveillance Sensor |
| Abstract: | The purpose of this project is to determine if an Ultra-Wideband radar array sensor can be used as an effective perimeter security sensor to detect, track and classify targets. 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. This project is feasible because Time Domain has demonstrated this mono-static, bi-static and multi-static radar capability with existing low cost hardware in several similar projects. Time Domain will leverage this hardware and experience with the UWB signal processing experience and strengths of our teammate, Applied Physical Sciences, to produce a UWB radar performance model, then validate the expected detection performance and produce a proof of concept. 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. |

| Abstract: | Guy cables are used to support tall man-made structures, including broadcast antenna masts. Failure of a guy cable results in destruction of the mast with significant damage and impact. We will design, build and prove a portable online robotic system with unique non-destructive examination capabilities to detect flaws which result in loss of cable strength. The methods used will include standard magnetic flux methodologies for detection of local flaws and loss of metallic cross-sectional area supplemented by QUEST Integrated proprietary technology to detect hidden internal corrosion as well as pitting and fretting damage in sub-surface layers of the metal cable. The device will operate on a range of cable diameters and will be designed for use in a `live' operational high-voltage radio frequency environment. Existing systems and proven technology will be adapted for use in this new application. Significant experience in measuring and modelling corrosion and fatigue in metal cable and knowledge of the key degradation mechanisms will be applied to automatic software recognition of typical flaw signatures. |

The proposed tool will utilizing recent advances in hybrid flexible/rigid printed circuitry fabrication to implement the main-flux measurement technique within a clamshell-type enclosure. This innovation will provide significantly greater sensitivity than current tools utilizing the `modified-main-flux' method while retaining the convenience of easy installation and operation. Integrating onboard signal processing and data storage, this tool will have the capability to transmit Loss of Metallic cross-section Area (LMA) and Localized Flaw (LF) data via a RF connection to a laptop or other suitable computer. Additionally, the tool will obtain close-up visual inspection of the cable using several cameras and transmit these images to the ground station to facilitate data analysis. Software hosted on the laptop will provide data analysis, archival, and comparison with historical data for a given guy wire. The tool will also use a novel method that will enable it to be readily adjusted for precision inspection of guy wires ranging in diameter between 1 and 3.5 inches as well as cables that have localized swelling. |

| 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. |

| 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. |

| 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. |

| 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. |
