摘　　要：现代雷达系统普遍采用旁瓣对消技术对抗旁瓣支援干扰,使得传统远距离大功率支援干扰往往难以奏效。在充分分析旁瓣对消系统的工作原理及薄弱环节的基础上,提出了一种多节点极化饱和干扰方法,并通过仿真将其与空域饱和干扰方法进行了分析与比较。仿真结果表明,2种干扰方法均能对旁瓣对消系统形成有效干扰,且相比之下,极化饱和干扰方法具有更高的效费比。Sidelobe cancellation(SLC)technique is commonly used in the modern radar system as an effec-tive approach of electronic counter-countermeasure(ECCM)against support jamming,which makes high-power stand-off jamming ineffective.Based on the full analysis of the principle and vulnerabilities of SLC,a multi-node polarization saturation jamming method is proposed.The simulation results demonstrate the effectiveness of the methods and the higher efficiency-cost ratio of polarization saturation jamming.

关 键 词：旁瓣对消 分布式干扰 饱和干扰 极化干扰
