Abstract

In this communication we present a method to correlate a scene with a filter using a binary joint transform correlator. The method consists in defining a suitable threshold function to binarize the joint power spectrum. By suitable binarizing the joint power spectrum it is possible to obtain correlations equivalent to those obtained with spatial correlation filters with a VanderLugt correlator. We analyze the problem theoretically and also provide some simulated results.
