Spaceborne synthetic aperture radar (SAR) image simulation methods are investigated in this paper.A new method is proposed based on fractal theory
facet model and clutter scattering characteristic model.Digital elevation model of a natural terrain is used in computer simulation.The simulation results demonstrate that the stochastic properties and special geometric distortion phenomena of natural ground scene spaceborne SAR image are reflected in the simulated images.The simulation method is suitable for verification of SAR satellite system scenario
and it has significant importance to realize the optimization of system scenario of SAR satellite.
