摘要
针对现代雷达信号带宽大、频率高,相干干扰实现困难的问题,提出了基于压缩感知的间歇采样转发干扰方法。研究了压缩感知基本原理及其对模拟信号处理的实现方法,分析了压缩感知对线性调频信号的间歇采样实现方法及其转发干扰效果。仿真结果表明,压缩感知理论对宽带雷达信号间歇采样具有较好的适用性,对宽带雷达能够实现较好的干扰效果。
For the difficulty of coherent jamming in wideband high frequency modem radar, a new method of interrupted-sampling repeater jamming based on compressed sensing is introduced. Com- pressed sensing theory and analog signal processing are studied, and the interrupted-sampling of LFM signals and the effect of repeater jamming are analyzed. The simulation results validate that com- pressed sensing is proper to the interrupted-sampling of wideband radar signals, and show perfect jam- ming effect to wideband radar.
