摘　　要：相控阵雷达普遍采用低旁瓣、旁瓣对消及旁瓣匿隐等抗干扰技术,使得远距离支援干扰机无法从旁瓣对其实现有效压制,而单机形成的主瓣压制区又过窄。根据干扰方程对单机干扰压制区进行了仿真分析,并建立了多机协同干扰模型,对多机协同干扰相控阵雷达时的配置问题进行了仿真研究,仿真结果表明,利用多机协同干扰相控阵雷达可有效改善干扰效果,且存在干扰机最佳布置间隔使得合压制扇区最宽。Anti-jamming technologies such as low sidelobe, sidelobe cancellation, sidelobe blanking, etc. are commonly used in phased array radar,which makes stand-off jammer（SOJ） can＇t realize ef- fective suppression by the side lobe, and the main lobe suppression area generated by single jammer is very narrow. This paper performs simulative analysis to jamming suppression area of single jammer according to the interference equation,and sets up the model of multi-jammer cooperative jamming,performs simulation and study to the configuration of multi-jammer cooperative jamming to phased array radar. The simulation results indicate that multi-jammer cooperative jamming phased array radar can effectively improve the jamming effect, and the best arrangement interval between jammers makes the co-suppression sector the widest.
