SARAS - A synthetic aperture radar (SAR) raw signal simulator
Abstract
An SAR simulator of an extended three-dimensional scene is presented. It is based on a fact model for the scene, asymptotic evaluation of SAR unit response, and two-dimensional fast Fourier transform (FFT) code for data processing. Prescribed statistics of the model account for a realistic speckle of the image. The simulator is implemented in SARAS, whose performance is described and illustrated by a number of examples.
