Detection Threshold Calculations for Cross Correlation Processing.

Abstract

Detection threshold calculations are performed for cross correlation processing of the received signals from two fixed omnidirectional sensors of a moving source generating an arbitrary random power spectrum. The effects of doppler decorrelation and volumetric absorption, and the degradation as a result of multiple bottom bounce and surface reflections are included. The equations for ROC curves are presented. A computer program which accepts as input the source power spectrum, noise power spectrum, averaging time, frequency analysis band, and sensor baseline separation solves for the detection threshold given a .5 probability of detection and .001 probability of false alarm.
