Evaluation of a Wideband Direction Estimation Algorithm for Acoustic Arrays

Abstract

Simulated data has been used to evaluate the performance of an acoustic target detection and direction estimation algorithm. The signals used to test the algorithm were simulated acoustic signals propagating across a nine-sensor, tri-delta array. Band-limited broadband sources as well as periodic sources were simulated. The outputs of the algorithm consisted of azimuth and power estimates along with a quantity intended as a quality measure for the azimuth estimates.
