摘　　要：雷达天线超低旁瓣技术和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,该文首先分析了远距离支援干扰的弱点和现代雷达采取的抗压制性干扰措施,然后提出近距离主瓣干扰战术和相参干扰技术组合的近距离相参干扰方法。文中给出了干扰机的原理框图,详细设计了干扰样式和干扰信号,并且分析了该干扰方法的功率和时频特性。计算机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 efficiency of broad band barrage Stand-Off Jamming （SO J） is decreased quickly with such techniques as radar ultra-low sidelobe antennas and narrow-channel filter. In allusion to this situation, the weakness of SOJ and Electronic Counter-CounterMeasure （ECCM） of modern radar against blanket jamming are analyzed firstly. Then, a blanket Stand-Forward Jamming （SFJ） method with close-in mainlobe jamming tactics and coherent phase jamming technique is suggested to apply. This paper puts forward a principle block diagram of the jammer and designs jamming mode and signal in detail as well. Furthermore, it investigates the characteristics of power and time-frequency of this jamming technique. Computer simulation indicates that this jamming technique is superior to broad band barrage SOJ.
