A radar image simulation model, which can be used to aid interpretation of images and information extraction from images, has been developed and implemented on a digital computer. The model, called the "Point Scattering Model," is a mathematically rigorous treatment of the stochastic process described by the closed system consisting of the radar transmitter and receiver, the ground dielectric properties and geometric orientation of features, and the radar image medium. The vital components of this model are shown to be the operating parameters of the radar, a digital model of the features in the terrain, and a reflectivity model for the features included in the terrain model. Radar images simulated by this model are presented in side-by-side comparison with actual radar images of the same site. The images are shown to substantiate the validity of the radar simulation model.
