The research proposed here is built on the recent successful fabrication of metal oxide semiconductor heterjunction field effect transistors (MOS-HFETs) based on AlGaN/GaN heterostructures with very high drain-current-driving and gate-control capabilitiesas well as unprecedented high breakdown voltages by the P.I.s research group at Kansas State University. III-nitride HFETs have great promises i ...

DESCRIPTION (provided by applicant): EIderly falls constitute one of the most costly health problems in the U.S., both in terms of expense to the healthcare system and in individual suffering. Fully one-third of people over age 65 fall each year, many incurring significant injuries that strongly impact their long-term health prospects and productivity. Although many factors contribute to the prop ...

Long-duration wide-area surveillance missions increasingly are space-based. MEO orbits offer space-based radar systems more time on station, but require very large array apertures on the order of 100m in diameter. Achieving larger apertures with smaller,lighter launch packages and stable on-orbit pointing is a challenge that E-Textiles promises to meet. Textile processes can be used to achieve a l ...

Digital Beamforming (DBF) technology offers several advantages to phased-array radar and communication systems over previous analog phase shifters including performance, versatility and cost. Previous array phase-shifter technology can be classified aseither fixed delay, employing switched delay lines, or variable delay, using ferrite phase shifters. The fixed-delay systems suffer from lack of ver ...

An X-band interferometric radar (XBIR) system employing digital beamforming (DBF) is proposed to supplement the S-band multi-mission radar (MMR) phased array currently under development by Syracuse Research. This auxiliary X-band array will bolt onto theapproximate 1.5 x 2.0 meter MMR array and provide a precision tracking capability for fire control. The two radars will operate cooperatively in v ...

Phased-array radar employing wideband digital beamforming (DBF) offers the potential for detecting and tracking incoming cruise missiles while defeating electronic countermeasures such as chaff, jamming and anti-reflective coatings. A wide instantaneousradar bandwidth is essential for defeating these threats, resulting in improved range resolution and target signature. Digital beamforming may be u ...

Ascension Technology proposes to develop a fast, six degrees-of-freedom tracker, phasorBIRD, immune to cockpit and helmet scatterers of magnetic/electrical field energy. It will integrate seamlessly with helmet-mounted displays in tactical aircraft,tracked ground vehicles, and combat air operations centers (CAOCs). Design features will enable it to exceed static accuracy and repeatability of the b ...
