Convolution Jamming Technique Countering LFM Radar
对线性调频雷达的卷积干扰技术

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.
