Abstract: The mathematical model of spaceborne SAR systems and its computer simulations are described. Results of computer simulations about range migration, range migration correction, azimuth weighting and azimuth signal generation/processing are given. This software can be used to simulate the dynamical process in spaceborne SAR system, to develop new signal processing technique and to evaluate the performance of the designed system. -
