This proposal will address the development of digital receivers and exciters capable of supporting > 1 GHz of instantaneous bandwidth (IBW). The technology will be used in large scalable BMD radar arrays employing a digital waveform generator and digital receiver at the analog input/output of each subarray panel. The receivers/exciters include the necessary up/downconversion and local oscillator c ...

In the proposed Phase II effort, Applied Radar, Inc. will develop a wideband scaleable digital beamforming (DBF) processor capable of supporting > 1 GHz of instantaneous bandwidth (IBW). The new patented hardware architecture paradigm developed in Phase I is scaleable in the number of input channels, the number of output beams, and bandwidth. Hence, it is directly applicable to large BMD radars su ...

The development of broadband high-isolation active circulators with simultaneous transmit and receive (STAR) capabilities would enable increased persistence in intelligence, surveillance and reconnaissance (ISR) systems and allow multiple simultaneous radar modes including SAR, GMTI and AMTI for global and local multifunction and multi-task operations. Previous works in MMIC active circulators dem ...

Our missile defense capability crucially depends on radar performance to detect, track and discriminate hostile targets. New radar designs being developed offer enhanced capability. However, a significant impediment to the deployment of these new radars is the high cost of active electronically scanned arrays (AESAs) and in particular the antennas upon which they are based. Together with our inter ...

DESCRIPTION (provided by applicant): BCR Diagnostics, Inc. (BCR) has recently developed and patented a technology platform for engineering fluorogenic functionality into living Bacillus spores. Fluorogenic spores (F-spores) produced at BCR appear to be physiologically identical to normal spores except for performing as self-reporters of initial germination events. ...

We propose a compact broadband underwater cylindrical transducer with directional capabilities for acoustic communications (ACOMMS) for unmanned underwater vehicles (UUVs) and gliders. Our proposed solution is to incorporate single crystals and directional capabilities into the acoustic modem transducer, thereby increasing overall system capability. BTech has designed and built improved modem tran ...

We propose a compact broadband underwater cylindrical transducer with integrated power amplifier for multiple applications, including acoustic communications (ACOMMS) for unmanned underwater vehicles (UUVs) and gliders. Such compact, modular devices could be used alone or arranged into various array configurations. On existing platforms, the power amplifier and tuning inductor resides within the i ...

This proposal is for the design and development of a new low cost directional acoustic sensor technology with integrated acoustic modem capabilities for distributed sensor systems. The study addresses the feasibility to significant improve legacy performance of current A-size directional sonobuoy sensors with a new sensor and processing approach and to establish performance predictions for the ne ...

A single crystal cylindrical ring transducer with multi-resonant broadband operation is described with counter measure and general purpose sonar applications.

The objective of this program is to demonstrate and miniaturize a new type of cryogenic expander, thermoacoustic expander (TAE), for space cryocoolers which provide the cooling power less than 50 mW and operate in the low temperature range between 40K and 10K for cooling SWIR, MWIR, and LWIR surveillance and interceptor systems. TAEs employ high energy acoustic waves generated with absolutely no m ...
