| Abstract: | The simulation of point target is a very important step in SAR (Synthetic Aperture Radar) system design. Based on the law of spaceborne SAR's motion and the analysis of the theories of SAR image processing, the models of earth oblate spheroid, satellite elliptical track and satellite posture shake were set up. The method of point target simulation is also presented.By using this simulated data and the R-D algorithm, the image of the point target is obtained. |
