Abstract

Synthetic Aperture Radar (SAR) raw echo simulation methods are studied in this paper. A simulation method is proposed based on fractal theory, facet model and clutter scattering characteristic model. Digital Elevation Model (DEM) of a natural terrain is used in computer simulation. The SAR raw echo simulation is realized in the frequency domain. The simulation results demonstrate that the method is effective, and the stochastic property and special geometric distortion phenomena of natural ground scene in the SAR image are reflected.
