Research on Spaceborne SAR Raw Data Simulation

In spaceborne SAR studying and designing, raw date simulation is a common tool. The method of spaceborne SAR raw data simulation is presented. This method is based on elliptical orbit model. Based on this method, a simulator has been applied to our spaceborne SAR test. The simulator can deal with real radar sensor parameters and orbit data, and the result of simulation is closed to the fact. In the end, the results of the point target and the three-dimensional (3D) extended scenes are explained. It shows that the spaceborne SAR raw data simulation is very efficient
