A new technique for enhancing correlation discrimination is achieved by using a fringe-adjusted joint transform correlator (JTC). This technique is found to yield significantly better correlation output than the classical and binary JTCs. It also avoids the computation intensive joint power spectrum binarization processing of a binary JTC
