摘　　要：针对间歇采样转发干扰生成的假目标分布呈现较强规律性的问题,在间歇采样转发干扰方法基础上,结合非均匀采样与噪声调制的方法,给出了一种基于噪声乘积调制的间歇非均匀采样转发的干扰方法。通过对目标雷达信号进行非均匀采样与噪声乘积调制,在距离-速度维度内产生压制性干扰效果。仿真实验结果表明,该方法能够克服传统间歇采样直接转发干扰的假目标分布规律的问题,增大了干扰的作用范围。Aiming at the problem that the distribution regularity of false targets generated by intermittent sampling repeater jamming is obvious, on the foundation of the intermittent sampling repeater jamming, this paper presents an intermittent non-uniform sampling repeater jamming method based on noise product modulation combining with non-uniform sampling and noise modulation.By performing non-uniform sampling and noise product modulation to the target radar signal, the suppressive jamming is produced in the distance-speed dimension.The simulation experiment results show that the method can overcome the problem of regular false target distribution of traditional intermittent sampling straight repeater jamming and increase the range of jamming.
