摘　　要：为了对雷达的距离跟踪系统进行有效干扰,在介绍距离波门拖引干扰过程的基础上,分析了雷达距离跟踪系统对距离波门拖引干扰的响应结果,指出了干信比、跟踪波门宽度和跟踪带宽对成功进行距离波门拖引干扰时选取拖引速度的影响。然后假设雷达采用Ⅱ型距离跟踪系统,对距离波门拖引干扰过程进行了仿真,验证了分析结果的正确性。In order to jam the radar range track system effectively, the process of range gate pull off is introduced, and the response result of the radar range track system to the RGPO jamming is analyzed The influence of the jamming to signal ratio, tracking gate width and tracking band width on the success of RGPO jamming is pointed out. Then, the RGPO jamming process is simulated provided that the II type range track system is used by the radar. The simulation result proves the validity of the analysis
