摘要：

The use of a simulated annealing algorithm to design quantized composite reference function (QGRF) filters is presented. Since the QCRF filters are spatial domain filters using finite quantization levels, they can be implemented al the output spatial light modulator of a joint transform correlator. The performance of the QCRF fillers has been tested, in which we have shown that the detectability, accuracy, discriminability, and reliability improve as the quantization of the filter increases.
