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 ...

DESCRIPTION (provided by applicant): The potential contribution of telomerase activity towards unregulated cell proliferation and tumor growth has yet to be determined, and currently used methods for the measurement of telomerase activity are too cumbersome to be employed in the clinic, or used to facilitate pharmacologic screening. There is currently an acute and urgent need for a rapid telome ...

DESCRIPTION (provided by applicant): The major objective of the proposed project is to develop methodology that will allow fast and efficient detection of infectious prion proteins prior to the onset of clinical symptoms. This includes the detection of infectious prions in mortal products, early ante-mortem diagnostic of the prion diseases, and developing experimental approaches allowing deline ...

Argon Engineering Associates presents an innovative approach to Direction Finding (DF), replacing analog Butler Matrix beamforming with an all-digital adaptive beam former. Argon proposes to implement FFT channelization before beamforming using FieldProgrammable Gate Arrays (FPGAs). This allows both beamforming and advanced signal detection algorithms performed in general purpose processors to u ...

Argon Engineering Associates proposes to create Early Correlation processing in Ship's Signal Exploitation Equipment by using Extensible Markup Language (XML) search of sensor Signal of Interest (SOI) intercept database using Electronic Warfare (EW/ELINT)report parameters. Correlated information will be posted immediately to the JWICS network via OSIS Evolutionary Development or Global Command an ...

Protecting the U.S. coastline with commercial and naval ports is important. Providing indications and warning to U.S. Navy ships in foreign harbors is an equally daunting task. Argon Engineering Associates proposes to develop a small, low-cost HF, VHF,and UHF sensor to search and monitor maritime bands, providing both Over-The-Horizon (OTH) and Line-of-Sight (LOS) warning capability. The system ...

Researchers at Astralux, Inc. in collaboration with Sterling Semiconductor, EMCORE Corp. and the University of Colorado at Boulder propose to develop hybrid SiC wafers using a novel technique. Specifically, our goal is to commercialize epi-ready 3-inchand 4-inch 4H and 6H SiC wafers for the emerging wide bandgap microwave device market. Our hybrid SiC wafers are complementary to the existing bul ...
