Paper Abstract

The techniques used for storing matched filters in image processing units of the optical matched filter image correlator (OMFIC*) type determine to a large extent the capacity and discrimination of the complete system. In this progress report of an ongoing investigation sponsored by the U.S. Air Force Office of Scientific Research (AFOSR), techniques and materials for storing matched filters are reported upon. Results are related by performance in the areas of diffraction efficiency, and signal to clutter measurements with selected imaging of targets in terrain scenes. Coherent and noncoherent addition of images for overlayed matched filter recording was investigated and is reported upon. Dichromated gelatins are used as matched filter recording media and the results compared with silver salt photographic materials. A formula is derived for MF capacity and the analysis extended to the case where the medium sets the resolution for MF recording.
