The Detectability of a Mine Using Replica Correlation (RC) and Echo-Echo Correlation (EEC)

Abstract

The detectability of a small target by means of active sonar must be discussed in terms of waveform characteristics and the signal processing used to extract the echo from interference. This report presents the target signature of a mine for large bandwidth-time product (BT) waveforms, and discusses the losses suffered when the echo is processed by Replica Correlation (RC) and Echo-Echo Correlation (EEC). It is shown that RC 'splitting' losses increase with bandwidth, while EEC losses are relatively independent of bandwidth and are much lower than RC losses. The detectability of this mine for a given scenario of false alarm rate, number of beams, sonar platform motion, and processing type is also included.
