This Phase II SBIR project will advance the technical readiness level (TRL) of our Phase-I-demonstrated strategy for mitigating radiation damage in GaSb/InAs Type II Strained-Layer-Superlattice (SLS) long-wave infrared (LWIR) detectors. Our mitigation strategy will be optimized for detectors to be deployed in interceptor seeker systems that will be exposed to radiation in the near-Earth orbital en ...

QuNav proposes to validate and prototype a TRansform-domain INS Mechanization and Algorithmic Correction (TRIMAC). TRIMAC utilizes joint time/frequency domain processing of inertial sensor data in order to mitigate INS drift in the absence of external navaids (such as GPS). Frequency-domain implementation is particularly designed to improve the inertial performance in high-vibration missile enviro ...

Nanohmics proposes to develop a hyperspectral imager for aft-looking sensing of phenomenology associated with target vehicles.The payload is designed to operate with existing components and has no moving parts.The high spectral resolution will provide feedback for signature models and the spatial resolution will allow the spectral signatures to be associated with specific phenomena.Approved for Pu ...

Explosions and high-velocity impacts can create strain rates on the order of 105 to 107 s-1. To simulate these events, first-principles codes require material models that are valid at these loading rates. Currently, the amount of test data, material models and material constants for this strain rate range is extremely limited, and an innovative and cost-effective laboratory test procedure is neede ...

HIGH-DENSITY ENERGY STORAGE AND FAST DISCHARGE WILL BE CRITICAL IN A VARIETY OF HIGH POWER AEROSPACE APPLICATIONS. CAPACITORS ARE IDEAL FOR THESE PURPOSES, AS WELL AS FOR POWER CONDITIONING AND FILTERING. UNFORTUNATELY, BULK POWDER-BASED DIELECTRICS USED IN CAPACITORS HAVE SEVERE LIMITATIONS, ESPECIALLY THE HIGH NUMBER OF SHORT-INDUCING DEFECTS CAUSED BY POOR CONTROL OF MATERIAL PROPERTIES IN CERA ...

An innovative discharge geometry for a very compact, area cooled, high average power CO2 laser employing a two mirror, waveguide-stable optical cavity is proposed. The specific Phase I result sought is the generation of an average CO2 output power of 1 W/cm2 of wall cooling area in a geometry that has a total cooling area of 140 cm2. A lightweight CO2 amplifier version of a future Phase II devic ...

EXPLOITATION IN MICROELECTRONICS OF THE VERY HIGH DIELECTRIC CONSTANTS OF FERROELECTRIC PEROVSKITES SUCH AS BATIO3 AND PZT HAS BEEN LIMITED BY MATERIALS PROCESSING AND COMPATIABILITY PROBLEMS. HIGH QUALITY FERROELECTRIC THIN FILMS HAVE NOT BEEN GROWN AT TEMPERATURES COMPATIABLE WITH STANDARD SI OR GAAS PROCESSING TECHNOLOGIES. A HUGE PAYOFF AWAITS ONE WHO CAN UNLOCK THE POTENTIAL OF FERROELECTRIC ...

APPLICATIONS OF HIGH-TEMPERATURE SUPERCONDUCTING MATERIALS TO TUNNELING DEVICES HAVE BEEN LIMITED BY FABRICATION PROBLEMS RELATED TO THE INTRINSIC ANISOTROPY OF THESE MATERIALS, TO THEIR EXTREMELY SHORT SUPERCONDUCTING COHERENCE LENGTH, AND TO THE POOR ELECTRICAL PROPERTIES OF THE NATIVE SURFACE OXIDE ON THE YBA2CUO7-X (YBCO) FAMILY OF HTSC MATERIALS. MAGNETIC FLUX-COUPLED SWITCHING DEVICES MAY BE ...

LIGHT DETECTION AND RANGING (LIDAR) TECHNOLOGY PROVIDES A POWERFUL MEANS OF IMAGING SPACEBORNE OBJECTS USING INVERSE SYNTHETIC APERTURE RADAR (ISAR) RANGE RESOLVE TOMOGRAPHIC RECONSTRUCTION PROCESSING TECHNIQUES. THESE ISAR TECHNIQUES, HOWEVER, BECOME INEFFECTIVE WHEN THE OBJECT IS ONLY VIEWED FOR A SMALL FRACTION OF A ROTATIONAL. THE FORMIDABLE SIGNAL PROCESSING REQUIREMENTS INHERENT IN AN ISAR I ...

DEPENDING ON THE PARTICULARS OF AN ENGAGEMENT SCENARIO, DOPPLER SHIFTS DUE TO THE RELATIVE MOTION OF A MISSILE AND A SENSOR PLATFORM CAN BE IN EXCESS OF 1000 MHZ FOR A COHERENT COE2 SENSOR SYSTEM. SINCE THE RESPONSE OF THE SENSOR'S HETERODYNE DETECTOR CAN BE DEGRADED BY AS MUCH AS 50% AT THESE LARGE OFFSET FREQUENCIES, A LOCAL OSCILLATOR CAPABLE OF BEING TUNED EITHER UP OR DOWN 1000 MHZ TO COMPENS ...
