Application of Detection Theory to the Measurement of the Minimum Detectable Signal for a Sinusoid in Gaussian Noise Displayed on a Lofargram

Abstract

A review of detection threshold concepts is followed by an investigation into published theory for the detection of signals in noise. A set of empirical formulae relating minimum detectable signal to some basic sonar system parameters is presented. The formulae are compared and a recommendation made as to which is the most useful for the calculation of an omnidirectional narrowband lofargram minimum detectable signal for power detection of sinusoidal signals in Gaussian noise.
