"System-design considerations are presented for an optical correlator that processes signals recorded on film from the synthetic-aperture radar of the SEASAT-A satellite. A strip-map image of the earth's surface is to be produced with a resolution down to 6.5 m along track (azimuth) and 25 m across track (range). The input film and the two-dimensional Fourier transform are described mathematically and their parameters given. Processing problems introduced by range curvature, antenna pitch and yaw, earth rotation, low PRF, etc. are handled by simple modifications to a standard tilted-plane correlator. Recommended system configurations, output parameters and system limitations are given"--Abstract, page 1. Radar Optical equipment. Optical correlators Canada.
