摘　　要：雷达天线超低旁瓣技术和雷达压缩滤波技术使得宽带阻塞式远距离支援干扰的效能急剧下降。针对这种情况,首先分析了现代雷达采取的抗压制性干扰措施,并介绍了"灵巧噪声"这种新的干扰技术,然后提出基于干扰组网的近距离主瓣干扰战术和"灵巧噪声"干扰技术组合的近距离相参干扰方法。给出了干扰机的原理框图,详细设计了干扰样式,并且分析了该干扰方法的干扰效能。仿真试验表明,此种干扰方法较宽带阻塞式远距离支援干扰有较大的优越性。The sharp decrease of the efficiency of the broadband barrage Stand-off Jamming （ SO J） is caused by the ultra-low sidelobe technology of radar antenna and radar compression and filtering technology. In allusion to this situation, the Electronic Counter-Countermeasures （ECCM） of mod- em radars against blanket jamming is analyzed firstly, and a new jamming technique called ＂smart noise＂ is introduced. Then, a blanket Stand-forward Jamming （SFJ） method combining the close-in main-lobe jamming tactics and the ＂smart noise＂ jamming technique based on the jammer netting is presented. The schematic diagram of the jammer is given, and a jamming mode is designed in de- tail. Furthermore, the jamming efficiency of this method is analyzed. The simulation indicates that the SFJ is superior to broadband barrage SOJ.
