Title:Ultra Low Power SATCOM Transceiver
Abstract: Design of an ultra low power satellite transceiver is needed, which is technically innovative in three areas. First, interoperability with non-geostationary satellite systems as well as conventional geostationary systems is proposed, allowing global coverage, very small antenna, large field of view, and near 100% availability even for poorly sited terminals. Second, digital signal processing techniques capable of low power operation in extreeme environments are proposed to achieve high data rate with low bit error rate, suppress stron, nearby, inband transmitters, and reduce the probability of detection or intercept. Third, development of digital and analog circuits, including application specific integrated circuit design, microwave solid state circuit design, will be investigated to minimize power consumption, increase reliability in austere environments, and reduce production costs. Together, these design innnovations will allow manufacture of units that are lightweight, rugged, easily deployable, and able to operate on a small battery for 30 days. The goal of this research is to valideate the achievability of cost, size, and power consumption objectives in a militarized unit while maximizing operational unitlity including hight data reae, wide interoperability (e.g., military/commercial, current/near future, frequency ability and geographic coverage), and maximum link availability.

Title:A Hybrid Collar for Combat Protection (HYCOPS) to Increase Survivability and Reduce Injuries to Crew Members
Abstract:The helmet for helmsmen and crew members helmet has evolved from a device to provide impact and projectile protection, into a platform for communications equipment, into today's complex system that includes sophisticated optical and head-mounted display systems. The resultant increase in size and mass has caused at least two problems not previously experienced by the increased G-force loads on the cervical spine of the CCM. Secondly, increased helmet size and mass increases the degree of slippage fo the helmet relative to the head, thereby reducing thevisual acuity of helmsman/CCMs using optical systems. During the proposed effort, the investigators will design a prototype Hybrid Collar for Combat Protection System (HYCOPS) using innovative air chambers and inflators for helmet and neck support as well as life jacket bouyancy, state fo the art body armor and energy absorbing materials, and an innovative thermal stress management system. Each of these technologies have been developed separately and will be commercially available. The proposed work will take these unrelated technologies and combine them into a system that meets SOCOM's needs to protect small craft helmsmen and CCCM against many of the hazards faced on missions and during training.

Title:Man Personal Dual-Band Miniature Beacon
Abstract:A miniature hand held smart I-band and K-band beacon transponder is proposed to provide location, data transmission, and IFF applications. Based on Sierra Monolithics SMP-1000 I-band Microponder, which has single, double, triple, and active pulse operations, the proposed beacon adds a k-band capability with smart band selections according to interrogation pulse frequency. For data transmission, its pulse position modulation (PPM) architecture will allow data input through an RS-232 data interface, transmission of SELCAL codes for IFF operation, and GPS location data. It's agile AGC receiver responds to weak as well as strong interrogation pulses in quick succession. The target life for it's 9-V battery power supply is 24 hours of continuous operation.

Title:Titanium-Composite Body Armor Plates
Abstract:Advanced Protection Products, Inc. (APPI) will use advanced materials and processes to develop and certify Very Light Body Armor (VLBA) plates that are capable of defeating a variety of ballistic threats. The VLBA plates will be designed using a titanium allow based metallic-composite armor system to provide cost-effective, lightweight protection. Composite facing and backing materials will be utilized to minimize the effects of front-face spall and rear-face deformation. Commercially available titanium alloys (Ti-6A1-4V, Ti-6A1-6V-2Sn) will be evaluated for the VLBA plate application. Titanium cost will be minimized by ordering to industry standard or commercial specifications for alloy chemistry; performance will be mazimized by specifying a heat-treatment schedule developed specifically for armor. Ballistic testing will be conducted to determine required thickness for the titanium and composite armor materials. NIJ-style ballistic testing (using a clay backing) will be conducted on the final design in preparation for SBIR Phase II NIJ Certification efforts.

Title:On-The-Aperture Patch Tuning (OTAPT) for Broadband Antennas
Abstract:Dynetics proposes the use of On-The-Aperture Patch Tuning (OTAPT) as a potential solution for broadband performance from a low profile antenna. This solution is based on the innovative concept of integration of digital switching of tuning elements directly on the aperture surface. A single patch antenna can then be digitally tuned to successively lower frequencies, modifying the patch dimensions to the new resonant dimension by adding small strips. This technology may, in principle, be used over extremely broad frequency ranges, limited only by the performance of the switching devices employed in the aperture. RF power requirements on the switching devices (PIN diodes or GaAs switches, for example) are low relative to both the total radiated power because the incident RF power is distributed over several devices. The switching devices are readily controllable by digital computer commands which could be incorporated into existing crew instrumentation. With appropriate dual (or asymmetric) feed this concept can support any required polarization, including dual- or variable- polarization.
