Abstract

An active sonar scenario in which the sonar array is placed at a relatively shallow depth and is prone to surface interference is considered. The array depth is either known or unknown, with known probability density function. The performance of two detectors representative of the detection approaches discussed is examined using a reverberation simulation generator (REVSIM). The performance comparison is made in terms of detector receiver operating characteristic (ROC) curves
