Abstract
SAR (synthetic aperture radar) raw signal simulation is an important tool for study and testing of different SAR processing algorithms and new SAR systems. In this paper, the system transfer function of spotlight-mode SAR is evaluated and its accuracy is described. And, frequency scaling algorithm (FSA) is employed to actualize the coupling relation between the range and azimuth in the 2-dimension frequency. An advantage of the frequency scaling algorithm is that it requires only FFT (fast Fourier transform) and complexity multiplication and avoids interpolation.
