摘　　要：雷达间的同频干扰属于雷达内部电磁兼容问题的一部分。同频干扰严重影响雷达对目标的正常探测与跟踪,严重时会导致接收机前端损坏,需采用抗干扰措施消除。对雷达同频干扰的危害进行介绍,分析同频干扰产生的机理,给出了降低或消除雷达同频干扰的有效技术措施。结果表明,雷达间同频干扰产生方式多样,抗干扰措施可以有效降低同频干扰,但都存在局限性。消除同频干扰最好在雷达设计之初就总体考虑。The shared-frequency jamming between radars is a part of electromagnetic compatibility within the radars essentially. It should be eliminated with anti-jamming measures because it may effect the radars’normal detection and tracking to targets,even damage the receiver front-end if the jamming is serious. In this paper,the harm of the shared-frequency jamming is introduced,the cause of radar shared frequency interference phenomenon is analyzed,and the technical measures to eliminate radar shared-frequency jamming are presented. The results show that the occurrence forms of shared-frequency jamming are various,anti-interference measures can effectively reduce the radar shared-frequency jamming,but they have limitation;and the best way to eliminate the radar shared-frequency jamming is to consider it at the begging of the radar design.
