摘　　要：首先指出压缩感知理论是突破目前超宽带系统干扰技术发展困境的方向之一,介绍了压缩感知理论在LFM信号处理中的应用,然后提出基于压缩感知的转发干扰系统结构和工作流程,给出了假目标欺骗干扰、密集假目标干扰和灵巧噪声干扰等三种干扰信号生成方法。最后对这三种方式进行仿真对比分析,结果表明了此干扰方法的可行性和有效性。The compressed sensing （CS） theory is introduced as a way to break through the existent difficulty in ultra-wideband jamming method development, and the application of the CS theory in LFM signal processing is provided following. Then the composition and workflow of a retransmitted jamming system based on CS are demonstrated, and the generation modes of jamming signal by false target deception jamming, intensive false target jamming and smart noise jamming are illustrated. At last, due to the comparative analysis through a simulation in these three modes, the feasibility and ef- ficiency of this method are verified.
