摘要：
We compare the performance of the nonlinear joint transform correlator, the nonlinearly transformed filter based correlator and the conventional linear correlator. The pattern recognition systems will be compared in the areas of correlation peak, peak to sidelobe ratio and the correlation width. We show that compared to the linear correlator, both types of nonlinear correlators produce better correlation performance. © 1990.
