Paper Abstract

The correlation performance of nonlinear joint transform correlator for input signals containing a target in the presence of the input scene noise that is disjoint with the signal is investigated. It is shown that the binary joint transform correlator outperforms other types of nonlinear joint transform correlator for lowpass scene noise. Correlation tests using computer simulations are presented. The nonlinear joint transform correlator performance is determined for various degrees of nonlinear transformations and different input scene noise parameters. The investigations indicate that the correlation performance is sensitive to the bandwidth variation of the small bandwidth noise and is less sensitive to that of the wide band noise.
