| Abstract: | A new chirp-encoded joint transform correlator with high pass filtering is proposed. For this correlator, the correlation peaks are focused in different output planes. This technique is found to yield better correlation performance than the classical and binary joint transform correlators. It also restrains effectively effects of harmonic orders generated by nonlinear operating on JPS. Computer simulated results for input scences with gray-scale object are given. |
