Abstract: Because of the shortage of image about echo simulator for Synthetic Aperture Radar, a method for measuring image parameters of radar signal is presented. According to this method, a set of device for simulator for radar scene image echo calibration is established. The paper includes some useful processing methods which realize the calibration of the image, such as quadrature demodulation, pulse compressing, image algorithm， filter algorithm and so on.
