Missiles, use electro-explosive devices (EEDs) to perform mulitple functions during operation. This effort seeks ways to improve on the EED"s reliability and lower the failure or inadvertent activation rate of these devices. During Phase I, SEA CORP investigated replacing EEDs with commercial off the shelf (COTS) automotive airbag inflators to perform the required pneumatic functions of variou ...

We propose the continued design, development and testing of spherical piezocrystal transducers and supporting technology including our gyroid transducer. The Phase II effort covers the modeling and demonstration of the gyroid transducer and comparison of performance with several piezocrystal and piezoceramic materials and testing in realistic environment. The electroacoustic performance will be es ...

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 ...

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 ...
