Abstract
Experiments on kth law nonlinearly transformed matched filters for optical correlation are provided. Experimental results for the images tested indicate that nonlinear matched filters produce good correlation performance in the terms of correlation peak intensity, signal-to- noise ratio, and peak-to-sidelobe ratio. The sensitivity of the kth law nonlinearly transformed filter to rotational changes of the input signal is investigated. It is shown that for the images presented here, up to a certain degree of input signal rotation, a highly nonlinearly transformed matched filter may produce a larger peak-to-sidelobe ratio than a conventional matched filter.
