The ability to rapidly detect, identify and monitor chemical agents remains a challenge of significant importance to the Armed Forces. Existing chemical sensing techniques have shortcomings that inhibit widespread implementation. To address this situation, Ryon Technologies is developing a portable instrument that is based on Rydberg Fingerprint Spectroscopy (RFS) in combination with mass spectro ...

We propose the development of a low cost compact low frequency transducer with associated electronics using a novel method.

Missile threats faced by our country are constantly increasing in lethality. The weapon used to counter such missiles is the kinetic interceptor. To work effectively, the reentry vehicle (RV) location must be precisely known. Confusing objects within the reentry complex make the key discrimination process very difficult. Coherent distributed aperture (CDA) radar represents an important advance in ...

Electronic Support (ES) systems are among the fundamental instruments used for threat detection onboard Navy surface, sub-surface, and air platforms. They are tasked to sense the RF environment, to sort out all emitters, measure key associated parameters, and contribute to a comprehensive situational awareness with respect to all activity occurring in the RF spectrum. As threat systems evolve, num ...

Experimental evaluation of the electromechanical properties of relaxor piezoelectric single crystals under stress, thermal, electrical bias conditions is proposed through the use of various dynamic and static evaluation methods. The proposed phase I effort concentrates on evaluation of properties of PMN-PT using resonant bars, and Lumped-Parameter (L-P) dumbbell resonators under pressure loading ...

Key to phased arrays that can scale to high frequencies, bandwidth and large apertures is an architecture that enables full digital beamforming and large-array performance with minimum electronics per element. Out of the three proven beamforming methods for phased arrays: analog, conventional digital and spread spectrum digital beamforming (SSDBF), just the latter scales well to large arrays at hi ...

Next-generation ground-based BMD radar is anticipated to employ a scalable architecture with multiple low-cost transportable arrays employing hundreds of thousands of elements per array. Low-cost analog array panels are to be employed in the array, and will typically contain a digital receiver/exciter (DREX) behind a subarray group of typically 64 or 256 elements. The combination of element-level ...

Key obstacles to extending OFDM to wireless links and networks at high frequencies with dynamic channels are inherent low performance to Doppler and power amplifier operation with high backoff. Other significant obstacles are multipath and impulsive noise. PEARL provides a solid communications infrastructure with support for incremental relevant capabilities including TRANSEC and LPD/LPI. For this ...
