The performance of high resolution SAR systems under degrading conditions such as uncontrolled platform motion can only be analyzed and evaluated by modeling the whole imaging system through simulation. A major scientific problem however, is the generation of SAR raw data in consideration of high numerical and modeling accuracy, as well as restricted computer time and space. This paper proposes a raw data generator for the simulation of a complex scenario containing the natural environment and man-made objects. The algorithm combines the precision obtainable in the time domain and the efficiency working in the frequency domain. The simulated raw data are processed with a modified (ω,k)-algorithm. They are analyzed to quantify the quality of the developed simulation tool.
