Abstract
This SBIR is concerned with the operational use of acoustic sensors mounted on an operating vehicle to detect and localize targets, including other vehicles, in the surrounding environment. In general, several classes of noise limit the performance ofthese types of acoustic systems. Two key classes are the near field noise generated by the platform itself and the far field noise generated by interferences.We addressed these problems with an innovative approach that allows the different noise problemsto be addressed individually. In particular, the DSR/TecFocus approach offers a combination of processing algorithms to provide effective cancellation of near field noise sources and the suppression of far field interference in the data output fordetection and classification processing. The Phase I project demonstrated that the innovative concepts proposed were viable. Viability was demonstrated both in simulations and in laboratory experiments. The thrust of this Phase II proposal is to continuedevelopment of the concepts and demonstrate the performance that can be provided by using acoustic sensors on an operating vehicle. This development will provide significant improvements in the performance of the acoustic system and will allow the Army tohave an improved awareness of the battlefield environment.
