摘　　要：针对线性调频雷达的相干干扰方式是当前雷达干扰技术的研究热点,本文以此为背景,详细介绍了移频干扰、余弦调相干扰和间歇采样转发干扰的原理以及干扰效果,并在此基础上提出了一种余弦调相和间歇采样复合干扰方法,理论分析与仿真验证的结果都表明,该复合干扰能够形成密集的假目标群,干扰效果远胜于单一的干扰方式。The coherent method for linear frequency modulation radar is currently a research hotspot in radar jamming technology. Against this background, this article provides a detailed introduction to the principles and jamming effects of frequency shift jamming, cosine phase modulation jamming, and intermittent sampling and forwarding jamming. Based on this, a cosine phase modulation and intermittent sampling compound jamming method is proposed. Theoretical analysis and simulation verification results show that this composite jamming can form dense false target groups. The jamming effect is far superior to a single jamming method.
