THE EFFECT OF NOISE LEVEL UNCERTAINTY ON DETECTION PERFORMANCE: A COMPARATIVE STUDY.
Abstract
This report is concerned with the problem of detecting signals in noise of uncertain level. The impetus for this study is found in many areas; however, the detection of underwater sound signals in an ocean environment provides the primary motivation. The purpose is to consider the detection performance of a number of different receiver designs operating in an uncertain noise level environment. A number of receiver designs are considered ranging from the hypothetical externally sensed parameter (ESP) receiver to a standard cross-correlation type of receiver and including the clipper cross-correlator. The ESP receiver is a possibly non-realizable receiver whose performance serves as an upper bound while the cross-correlator is often used in practice. The design of the receivers investigated is briefly considered. The detection performance is displayed by means of receiver operating characteristic (ROC) curves for each receiver. (Author)
