Simulation of Synthetic Aperture Radar II: Simulating SAR (Synthetic Aperture Radar) Using the Advanced Visual Technology System

Abstract

The Advanced Visual Technology System (AVTS) computer image generator was modified to produce highly accurate simulations of synthetic aperture radar (SAR) reflectively and elevation effects that can be precisely correlated with corresponding visual and infrared imagery. The resulting SAR snapshot is a plan view of the selected patch area with the field-of-view corresponding to a selected scale of 0.65, 1.3, or 2.6 nm. The image generator is interrupted for only one frame time, during which the entire processing power of the AVTS, up to 4,000 polygons, is brought to bear on the SAR snapshot. Once the SAR patch is computed, the AVTS continues with visual and infrared processing. A post- processor then adds feature and terrain shadows, horizontal and vertical incidence effects, resolution fall-off in azimuth and range, and speckle.
