The capability to identify radar signals from enemy fighters about to launch a semi-active air-to-air missile would allow jamming before launch. If the attacking radar could be recognized within the first several pulses, the aircraft under attack would have this capability. Advent Systems proposes a nonconventional approach to the identification problem by using both intrapulse and c ...

As the size of staring sensors increase, the bandwith to move data off the focal plan increases proportional to the number of pixels in the array. For analog focal planes increased bandwidth also means increased noise. Readout noise limited systems will be less sensitive, detector noise limited systems may become readout limited at the higher bandwidths. Power dissipation will also increase wit ...

We propose a highly accurate surface profile data collection device that can be used to measure the buildup of ice on aero-surfaces. The device will be able to remotely collect the required data in a very short time and can be used for measurements of both static or rotating surfaces. By combining moire topography, a pulsed laser, and a digital data collection system, surface characteristics of ...

AstroPower proposes to develop high performance, room temperature, mass-producible, low-cost infrared detectors using liquid-phase heteroepitaxy of lattice-matched InGaAsSb and AlGaAsSb on GaSb substrates. The structure of these detectors will be a Separate Absorption and Multiplication Avalanche Photodiode (SAM-APD). This structure has proven to be an effective means of producing large gain in ...

Avyd Devices proposes a Molecular Beam Epitaxy (MBE) growth based HgCdTe heterostructure photodiode approach to develop a technology capable of producing VLWIR HgCdTe arrays with high performance, high tolerance to nuclear radiation, high uniformity, high operability, and high yield for use in low background space environments. These essential elements of the approach entail: ¿ Heterostructure g ...

V-band (60 Ghz) solid state power combiner capable of producing 5 Watts and higher cw output power for intersatellite communications is proposed. Supported by Lockheed-Martin providing high performance and high reliability MMIC amplifier chips, highly efficient combiner circuit will be developed with multiple MMIC chips. The combiner will feature low loss in power distribution and combination, h ...

Success in aquaculture depends heavily on delivery of oxygen to fish. Currently, liquid oxygen and on-site generation by pressure swing adsorption (PSA) are two methods for supplying oxygen to aquaculture. Both are costly and have absorption efficiency problems. Membrane contractors, paddle wheels, and porous pipes are used with limited success to enhance oxygen transport to aquaculture. We ha ...

Rising increases in semiconductor capabilities have changed face of ASIC design. Designers recently demanding increased die densities are now concerned with how they can afford the NRE to design a complex ASIC. Gate counts have far outpaced design tool capabilities, measured in gates designed per engineer-day. Automated VHDL generation is a potentially promising field, but the approach has faile ...

Vibration-induced failures occur frequently in critical avionics modules and sensors in high performance aircraft, often resulting in loss of mission, a downed aircraft, and costly repairs. We propose to augment passive isolation mounts for these devices by adding active piezoelectric elements. This synergistic combination could lead to a dramatic reduction in avionics and sensor failures caused b ...
