Innovative Active Sonar Signal Processing Phase I SBIR - July 2015

Centreville, VA

Adaptive Methods, Inc. of Centreville, VA was awarded a Phase 1 SBIR contract for innovative active sonar signal processing. Current adaptive signal processing algorithms suffer from sample support limitations due to the rapidly changing active environment. In order to prevent signal suppression and maintain robust performance, these algorithms must be run conservatively, limiting their ability to null clutter and interference. The approach Adaptive Methods outlines for Topic N151-034 Active Signal Processing Enhancements for Classification of Low Signal-to-Noise Ratio (SNR) Sonar Signals in Doppler Clutter, builds upon experience in rapid adaptation to provide the next generation of active signal processing. The Robust Active Signal Processing Adaptive Processor (RASAP) concept enables aggressive robust adaptation in sample-starved environments. This approach mitigates the corruptive effects of interference and leakage while minimizing impact on downstream processing, leading to improved detection, tracking, and classification performance
