摘　　要：针对远距离支援干扰机难以通过旁瓣对相控阵雷达实施有效干扰,而主瓣压制区又过窄的问题,提出了一种基于航迹协同的相控阵雷达干扰方法,使突防飞机始终处于雷达主瓣压制区内。建立了突防飞机、干扰飞机三维航迹协同模型,对不同情况下的最小掩护距离进行了仿真分析。仿真结果表明,严格的航迹协同和参数规划可改善干扰效果,有效掩护航空兵突防。Stand off jamming （SO J） is difficult to interfere effectively phased array radar by the side lobe, and the suppression area of main lobe is very narrow. In order to interfere enemy phased array radar, a feasible interference method based on collaborative track that makes penetration aircraft always stay in main lobe suppression area of phased array radar is put forward. The model of three-dimensional col- laborative track of penetration aircraft and jamming aircraft is established, and the minimum cover distance under different circumstances is simulated and analyzed. Simulation results indicate that strict track collaboration and parametric programming can improve the effect of interference and protect effectively our penetration aircraft.
