In the paper, a method of moving target detection and parameters estimation is proposed used for dual channels Wide Area Surveillance (WAS) radar based on high resolution Doppler Beam Sharpen (DBS) image. First, it analyzes characteristics of clutter and moving target return, and presents the ways of clutter suppression and moving target parameters estimation. Then, an approach to decrease errors of parameters estimation is proposed. At last, an effective approach to resolve the ambiguity caused during estimating moving targets parameters is proposed. The effectiveness of the presented method is demonstrated by both simulated data and real data.
