Abstract
Coordinated Anti-Submarine Warfare (ASW) tactical operations frequently hinge upon the ability of our airborne assets to detect, classify, localize and prosecute enemy submarines who possess formidable offensive and defensive capabilities. This is becoming increasingly difficult as enemy assets get quieter and the acoustic environment becomes increasingly crowded. The Navys airborne ASW passive and active sensor systems must contend with friendly sonar system interference, non-cooperative in-band signal interferers, commercial active sonar signals, environmental noise, and biologics which all contribute to unacceptable performance losses. In-Depth Engineering Corporation proposes the Cortical Location and Elimination of Acoustic Noise (CLEAN) solutionan innovative, software-only acoustic noise removal algorithm based on a model of the early stages of sound analysis that occurs in the primary auditory cortex of the brain of a mammal. The CLEAN solution is designed to isolate disparate sources of sounds in a high-dimensional representation of a noisy acoustic signal and to remove the noise, providing a clean version of the original signal. The CLEAN algorithm mimics the ability of mammals to tune their acoustic receptive fields in order to attend to one sound over other competing sounds.
