摘　　要：针对现代雷达普遍采用脉冲压缩体制，普通非相干干扰难以对其形成有效干扰的问题，提出了一种基于卷积调制的间歇采样转发干扰的相干干扰样式。这种干扰样式的干扰信号是将间歇采样雷达信号与特定信号卷积形成，与雷达信号具有相关性，可以获得雷达的压缩处理增益。干扰信号频谱范围同雷达信号一致，提高了干扰功率的利用率。合理的选择卷积信号，可以灵活的起到欺骗干扰和压制干扰的效果。Aimed at the problem that pulse compression is broad used in modem radar and the effect of normal jamming is not good, a jamming method of interrupted-sampling repeater jamming based on convolution modulation is presented. The jamming signal is obtained through interrupted sampling radar signal eonvolved with a certain signal. The jamming signal has relativity with radar signal. The compression gain can be acquired. The frequency of jamming signal is coherent with radar signal, and the using rate of jamming power is enhanced. The effect of blanket jamming and deception jam- ming is gained by selecting convolution signal properly.
