Paper Abstract

We analyze the performance of the nonlinear joint transform correlator in terms of output peak to peak standard deviation ratio. The main assumption used is that the signal energy is small relative to that of the additive noise; this assumption is defensible in practice due to the generally small spatial extent of target images relative to scenes. This work is an extension of that in two earlier papers. The analysis in these was in terms of the ratio of the expected values of correlation peak to noise floor. In the current paper we extend this to study the variability of the correlation peak itself.
