摘　　要：现代雷达普遍采用自适应旁瓣对消(ASLC)技术抑制有源干扰,而其强抗干扰性能使得干扰机单纯依靠提高干扰功率的方法不再奏效。分析了ASLC系统的工作原理,并仿真验证了ASLC系统对抗旁瓣干扰的有效性。在此基础上,介绍了多方位饱和干扰和异步闪烁干扰的干扰原理,并分别进行了仿真分析与比较。仿真结果表明两种干扰方案均能对ASLC系统取得较好的干扰效果,且相比之下,异步闪烁干扰效果更佳。Adaptive sidelobe canceling （ASLC） is commonly used in the modern radars against active jamming, and its strong anti-jamming performance makes the method that jammers rely solely on the increase of interference power no longer works. The working principle of ASLC sys- tem is analyzed, and the simulation results show effectiveness of ASLC system to cancel side- lobe interference. On this basis, the principle of multi-direction saturated jamming and asyn- chronous twinkle jamming are introduced, by means of the simulation analysis and comparison, the results show that the two schemes can achieve good interference effect on ASLC system, and by contrast, asynchronous twinkle jamming is better.
