As a kind of active microwave remote sensing, Synthetic Aperture Radar has become one of main directions of development of remote sensing. Because SAR imaging process overmuch depends on the sensor and the scattering characteristics of ground object, it not only brings us some limitations on obtaining image, but also introduces errors into SAR image during obtaining image process. These problems will be discussed in this paper. We firstly review the computer simulation technique in remote sensing, the scattering characteristics of ground object and the SAR imaging mechanism. Next, we propose computer simulation SAR system which integrated the subsystem of sensor and imaging、the subsystem of scattering characteristics of ground object and the subsystem of information retrieval into one to produce SAR simulation images using computer completely. This system can produce dynamically SAR images not only in various kinds of incident angle、wavelength and polarimetric ways of sensor, but also in different phases of ground object、vegetation variation. Using this system, we can replace field work, save time and expenses, and avoid the risk arose by wrong decisions and operations.
