摘　　要：为了从杂波中检测出目标,提出了抑制杂波的一种新方法——速度滤波与Hough变换的结合应用。文中根据2种方法各自的优缺点,将雷达扫描的不同区域采用不同的方法处理,并与"滑窗"检测法并用,有效的检测出直线运动的目标,达到高效率杂波抑制的效果。通过多次试验研究,得出速度滤波法对虚警率和漏警率的影响,同时给出了结合Hough变换后,对虚警率和漏警率的影响,从而验证了此方法的有效性。此方法算法简单,计算量小,杂波抑制效果很好。In order to detect moving targets in clutter, a new method of clutter suppression is proposed--speed filter connected with Hough transform. According to the advantages and disadvantages of the two methods, different methods are taken with the ＂sliding window＂ assay in different regions of the radar scanned, the linear moving target is detected and high efficiency and the effect of clutter suppression is achieved effectively. In this paper, several experiments are studied, the influence is made with the method of speed filter on the false alarm rate and missed alarm rate, and when combined with Hough transform, the different influences appear on the two facts. In a word, this method is simple, and its calculation is small, besides, the method of clutter suppression works well.
