Abstract This paper presents a new SAR Doppler slope filters method for detecting the cross range velocity of moving target. This method builds the Doppler slope filter group recursively and reduces the amount of operations. By analysis on the detection precision and range of target speed, the advantage and the limit of this method are indicated. The detection results from real data demonstrate the accuracy of the conclusion.
