摘　　要：随着无人机威胁的逐渐增大,利用传统中远程雷达完成城市、山地等复杂地形区域无人机探测所需代价极高。利用近程雷达组网完成区域覆盖成为一个重要技术方向,然而大量雷达组网的实现还需要解决雷达间的互相干扰问题。文章介绍了雷达组网的蜂窝分布模型与干扰信号形式,然后提出综合采用频率分集、波形分集与信道抑制的干扰抑制策略,对不同等效距离的干扰进行抑制,并给出了典型参数下干扰抑制策略分析。With the increasing threat of unmanned aerial vehicles(UAV),the traditional medium and long range radar has a high cost for UAV detection in complex terrain areas such as cities and mountains.It is an important technical direction to use the short-range radar network to complete the area coverage.However,the mutual interference between radars needs to be solved for the realization of a large number of radar network.This paper introduces the cellular distribution model of radar network and the form of jamming signal,and then puts forward the jamming suppression strategy of combining frequency diversity,waveform diversity and channel suppression to suppress the jamming of different equivalent distances,and gives the analysis of jamming suppression strategy under typical parameters.
