Outdoor acoustics simulation plays a vital role in several army and defense-related applications, such as minimizing the noise profile of reconnaissance vehicles to avoid counter-detection, optimizing sensors and systems for tactical advantage, and pinpointing the origin of gunshots using their acoustic signatures. Outdoor acoustics prediction technology is needed to efficiently model large, compl ...

EE Boost Inc. proposes to develop a new, fast and accurate hybrid wave-based method for acoustic simulation in large and complex environments. The hybrid method combines two efficient methods: the pseudo-spectral time-domain (PSTD) method and the enlarged cell technique (ECT). The PSTD method is extremely fast and accurate in computing fields in large cuboids without internal boundaries and interf ...

Bridger Photonics and the University of Arizona will develop a passive multi-band compressive sensor for imaging and object recognition applications. The Army has identified a need for multi-band imagery for intelligence, surveillance and reconnaissance missions among others. Multi-band systems offer enhanced discrimination capability and the ability to perform in adverse conditions (at night, smo ...

Highly scalable parallel random number generators (RNGs) will be developed, evaluated and implemented for use in high performance computing on thousands of multi-core processors and general purpose graphics processing units. The main contributions are: (a) design and implementation of new parallel test methods that capture the inter-stream correlations exhibited in practice and complement the curr ...
