Abstract This paper presents a new method for moving target detection using SAR. With the help of short FFT analyses and CFAR detection, this method calculates the moving parameter of the target from range migration effect. An analysis on the detection precision and range of target speed is given in the following characters. The advantage and the limit of this method are indicated and the detection results from real data demonstrate the accuracy of the conclusion.

Key words： Synthetic aperture radar Moving target detection Range migration
