1 September 1990 Detection and classification using higher-order statistics of optical matched filters
Author Affiliations +
In this paper we consider the problem of detection and classification of signals in the presence of additive Gaussian noise of unknown covariance (AGN/TJC), using higher than second-order statistics (HOS) of the output of a matched filter. Specifically, we apply the HOS-based method developed in [1,2] to phase-only matched filters. The main result of this paper is that the HOSbased statistic is appropriate for use with phase-only matched filter (POMF) outputs. Simulation results are presented which indicate the ability of the matched filter and the POMF, which are augmented with 1105, to detect a 2-d signal at signal-to-noise ratios below which the matched filters alone are incapable of making a detection.
