Abstract SAR image simulation of complex target is very important to radar target recognition and SAR image interpretation. In this paper, the raw echo is simulated by assembling scattering coefficients of the target, under the different aspect and frequency. These coefficients are obtained by applying shooting and bouncing rays technology onto the target’s 3D model. Via improving the traditional assumption of incident plane wave as the spherical wave, the algorithm is extended to be suitable for the near-field condition, as well as the far-field. Standard target experiment validate the algorithm can simulate full polarimetry, multiple aspect and wide bandwidth SAR echo. The simulated images of complex targets are very similar to the real data.
