摘　　要：无人机集群抵近式干扰是一种新型电子对抗技术,通过分析抵近式干扰的优势,重点针对抵近饱和对抗雷达副瓣对消(SLC)和干扰信号合成效应,从理论出发,分析了多通道饱和干扰条件下,对SLC自适应对消矩阵权值计算的影响机理,同时分析了破坏SLC条件下干扰扇面的叠加效应。结合典型雷达参数和干扰参数,开展了干扰效果的信号仿真和效能仿真,验证了无人机集群抵近式饱和干扰的作战效能。The standin jamming(SIJ)of unmanned aerial vehicles(UAVs)swarm is a new type of electronic countermeasure technology.By analyzing the advantages of SIJ,this paper focuses on the proximity saturation antagonizing radar side-lobe cancellation(SLC)and jamming signal synthesis effect,from the theoretical point of view,analyzes the influence mechanism on the weight calculation of SLC adaptative cancellation matrix under the condition of multi-channel saturation jamming,and analyzes the superposition effect of jamming sector under the condition of destroyed SLC.Combined with typical radar parameters and jamming parameters,the signal simulation and efficiency simulation of the jamming effect are carried out,which verifies the combat efficiency of UAVs swarm saturation standin jamming.
