Two Channel Passive Signal Detection,

Abstract

This report derives the optimum likelihood ratio receiver for detecting the presence of a Gaussian noise like signal masked by a background of Gaussian noise. Two channels of information are used to include the effect of a directive signal source. The mathematics of this problem is considered in some detail since it is applicable to the active sonar problem as well as the passive problem. The report is written for the reader who has not been exposed to the spatial processing problem but does have the necessary background in detection theory. For the more advanced reader wishing to pursue this topic, the report by Van Trees and the paper by Edelblute, et al. are highly recommended.
