Invariant methods of wideband acoustic signals detection and target localization

Abstract

A new invariant to the target Doppler spectrum algorithm of an acoustic signal detection and target localization is suggested. Statistical synthesis of the signal detection algorithm has been carried out under the assumption of a normal signal and noise probability density function for the case of a spatially distributed multi element acoustic antenna. The method developed can be used for both passive and active target localizations. Experimental results are presented.
