Abstract

One of the most successful optical signal processing applications has been optical architectures for converting synthetic aperture radar (SAR) data into images of the radar reflectivity of the ground. Pattern recognition using optical correlator technology has also been extremely successful, and generalized multiple filter techniques have allowed the implementation of invariant target recognition systems. A simple non-linearity in the form of an optically addressed spatial light modulator to remove random phase terms has enabled the cascading of these two architectures. Experimental verification of this cascaded non-linear optical processor using SAR data from the Shuttle Imaging Radar-A mission is presented. SAR images are formed and used as the input to an optical matched-spatial-filter correlator that successfully recognized ground features.
