The purpose of this report is to present the validation of the Point Scattering Radar Image Simulation Model and its software implementation developed at RSL Remote Sensing Laboratory, University of Kansas, Lawerence, Kansas. The work was sponsored by ETL Engineer Topographic Laboratories, U.S. Army, Fort Belvoir, Virginia. Two different instances of model validation are reported. First is validation of both SLARSide-Looking Airborne Radar and PPI Plan-Position Indicator radar simulation models by comparison of simulations to real images of exactly the same ground swath having the same look direction and other flight parameters. Second is a quantitative validation of a PPI model specialized to making reference scenes for a terminal guidance system using the Correlatron. The results obtained have shown the simulated radar images to be accurate representations of the ground scenes at the microwave frequencies they modeled. The comparisons were shown to be very favorable. Preliminary results of the guidance test have been very satisfactory. Data base construction techniques are also discussed. Alternate input intelligence data sources high-resolution aerial photographs, maps, ingra-red for feature extraction are reviewed. A conceptual design for an interactive feature extraction system is discussed.
