| 摘 要： | 根据线性调频雷达信号处理的特点,该本文提出一种新的应答式干扰技术--卷积干扰,即干扰机接收到雷达照射信号后,用某视频信号与接收信号卷积后转发.阐述了卷积干扰的机理,分析了干扰信号的时频特性,讨论了干扰功率及干信比方面的优势.理论分析证明,卷积干扰对线性调频雷达具有显著的干扰效果.根据视频信号的不同,干扰机能产生假目标欺骗干扰和噪声覆盖干扰两种效果,且需要较小的干扰功率.仿真实验表明理论分析的正确性和实际应用的可行性.

| Abstract: | In this paper, a new method is proposed for jamming the Linear Frequency Modulation (LFM) radar, which is based on the feature of the LFM signals processing and is named convolution jamming. The jammer receives the radar signal and convolves it with the expected video frequency signal. Then the convolution result is retransmitted. It can produce false targets deceptive jamming or noise cover jamming according to the video frequency signal. Theoretical analysis and computer simulation justify the validity and efficiency of the new jamming technique. |
