Clutter Effects on Optical Correlators

Abstract

We examine the effect of varying ground clutter on the performance of optical correlators. We compare the classical matched (CMF), phase-only (POF), and binary phase-only (BPOF) filters. A new definitions of the signal-to-clutter ratio (SCR) in the input scene and the signal-to-noise ratio (SNR) in the correlation plane is presented. Simulations show the POF and BPOF always outperform the CMF. The BPOF performs best in scenes with low SCR ratios (high clutter) using the new metric. The POF performs best for all levels of SCR when a block is placed in the filter plane.
