Abstract

The continuous need for aerial reconnaissance in its many forms has engendered support for studies to screen, process, and interpret the reconnaissance information. Some of these investigations deal with coherent optical signal processing approaches. In this paper, the authors describe the Grumman developed Optical Matched Filter Image Correlation (OMFIC) system. This automatic high speed system operates by processing photographic or other forms of imagery through multiple holographic memories of high density and effecting correlation between the input and stored imagery. The sensitivities of the matched filter to various target parameters were determined in this study, and they form, in general, the basis for establishing the memory. Three typical terrain models were processed for correlation and signal-to-clutter ratio. Estimates are given regarding processing speeds and their relationship to photointerpretation processing time.
