Multiple target detection using a modified fringe-adjusted joint transform correlator

Abstract

We investigate the performance of a modified fringe-adjusted joint transform correlator for detecting multiple targets present in an input scene. This technique, involving adjustment of the joint power spectrum (JPS) on the basis of the input-scene-only power spectrum, and apodization of the modified JPS on the basis of the reference signal power spectrum, is found to yield good correlation output. Simulation results are presented to verify the performance of the proposed technique.
