Based on the analysis of SAR imaging geometry and characteristics of satellite orbit parameters, This article mainly introduces RD location model, radar equation, backscattering model, principle of simulating SAR image and so on. The Range Doppler (RD) geo-location model is used to calculate the position of the radar imaging point for each grid point of the DEM. The SAR image is simulated and extracts the local incidence angle, projection angle and so on. The simulated SAR image coincides with the real SAR image texture through simulation experiment, which is beneficial to the automatic registration of the control points, especially in the mountains, where is very difficult to get the ground control point.
