对灵巧噪声干扰概念的表述提出了质疑。基于匹配滤波器理论对灵巧噪声干扰的本质含义进行了分析。对灵巧噪 声干扰与旁瓣消隐技术的关系进行了探讨。文中指出:对于旁瓣消隐技术消隐旁瓣干扰的作用,灵巧噪声干扰没有影响; 对于利用旁瓣消隐封闭雷达,采取灵巧噪声干扰可以在一定程度降低对于干扰功率的要求,但对于主天线主瓣增益与辅 助天线增益之差造成的对于干扰功率的要求没有影响;雷达为应对灵巧噪声干扰,应进一步压低主天线旁瓣,以增大主天 线主瓣增益与辅助天线增益之差,使得敌方即使采用灵巧噪声干扰,也很难或不能封闭雷达。

The statement about concept of smart noise jamming is oppugned in this paper. Based on matching filter theory, essential signification of smart noise jamming is analysed. And than, relationship between smart noise jamming and SLB is discussed. It is pointed out that smart noise jamming have no effect on function of eliminating side-lobe jamming of SLB; for utilizing SLB to block a radar, using smart noise jamming can reduce request for jamming power in a certain degree but have no effect on request for jamming power from difference between the main antenna gain and the assistant antenna gain; for answering smart noise jamming, the radar ought to further reduce side-lobe of main antenna to increase difference of the main antenna gain from the assistant antenna gain and make it more difficult to block a radar by smart noise jamming.
