摘　　要：对同方位有多部同型雷达存在的情况,要正确分选出目标的数量及每个目标的天线扫描方式和扫描参数是十分困难的。这里给出一种有效的信号分选方法可以解决上述问题。利用每个包络的到达时间进行积累差直方图统计,对每个直方图统计结果进行判断,进而分选出不同特征的扫描雷达信号。该方法的优点就是能正确分选出同型的扫描信号和扫描类型。对多部同型雷达在同方位出现时,不会出现虚警和漏警。For the situation of multiple radar signal of the same type in the same direction, it is very difficult to sort the target number and antenna scanning mode scanning parameter of each target.This paper puts forward an effective signal sorting method to solve the problem.The histo gram statistics of the accumulation difference is performed by using the time of arrivai （TOA） of each envelope, and then the result of all histogram statistics is judged, thereby scanning radar sig nals with different property are sorted. Correctly sorting the scanning radar signal and scanning type of the same type radar is the advantage of the toothed,and when multiple same type radar ex ists in the same direction,false alarm and missing alarm will not appear.
