USE OF OPTICAL CORRELATION FOR CODED SIGNAL IDENTIFICATION.
Abstract
Potential use of an optical correlator for identification of pulse compression signals was investigated using a linear FM signal. The test signals were of the hard clipped variety and were designed to simulate the linear modulation using spatial rather than time coordinates. Signals whose time-bandwidth products range from 50 to 100 were correlated and resulted in selection of a time-bandwidth of five for channel separation in production of multiple channel transparencies. Tests were run using reference transparencies with 11 channels. Channel widths of 2mm to .5mm were used with satisfactory discrimination of the input on a multiple channel photographic output. Results differed little with changes in channel size. The study showed reasonable potential for using optical correlation for discrimination of pulse compression signals and a need for better signal transparencies and improved output systems. (Author)
