Abstract

An intelligent Synthetic Aperture Radar simulation system can be used to optimize the design of SAR system parameters and select optimum SAR data acquisition mode. Previous research mainly focused on simulating geometric characteristics of SAR image, lacking of radiometric consideration in flat areas because of the complexity of the problem. The popular geometric model of Range Doppler Equations cannot be applied to SAR sensor pre-launched as it relies on so many parameters contained in the original SAR data. In this paper we develop a new simulation system based on simplified geometric model and statistical radar scattering model for different thematic contents. It can generate simulated SAR image product at different bands, polarizations, incidence angles and resolutions, according to user's need. As an experiment, a simulation example of ENVISAT ASAR is compared with the real data collected, to demonstrate the utility and correctness of the system.
