Detection Threshold Modelling Explained

Abstract : This document presents expressions for modelling the detection threshold for narrowband and broadband passive sonars using either power or amplitude detection, cross correlation sonars, CW and FM active sonars with or without replica correlation, as well as intercept sonars. Explanations of various terms are given, along with appropriate ROC curves and recommended default values for those cases where insufficient information is available to the modeller. Intended users of this document are sonar modellers and operations research modellers who want quick and credible answers without going into the fine detail of the sonar system's operation.
