Abstract

The U.S. Army Research Laboratory (ARL) has been developing advanced acoustic array signal processing algorithms using small baseline arrays for detecting, performing direction finding, tracking, and classifying ground targets. In this paper, we discuss the wideband MUSIC algorithms and the real- time implementation of these algorithms in the ARL sensor testbed. Computational complexity issues and CPU platforms pertaining to the testbed are discussed. In addition, we present experimental results for multiple targets test runs showing the relative performance of the delay-sum and the incoherent wideband MUSIC algorithms versus ground truth.
