Single-Look Detection with Unknown Signal Strengths

Abstract

This problem concerns receiving two different waveforms that contain either noise or signal plus noise. The number of signals present is to be determined. The signal amplitudes are unknown parameters of the problem. Classical results involve estimating the unknown parameters and selecting the most likely condition. However, the total probability of error for the detection of the number of signals by using the classical procedure is high. Consequently, several alternate detection procedures are developed. All methods considered give better results than the classical method, although no single method is found to be always best. The effect of correlated noise is also investigated.
