摘　　要：为研究线性调频脉压雷达有效相干干扰,提出一种间歇采样灵巧噪声转发干扰.首先根据干扰信号特征,理论上分析了基于间歇采样的灵巧噪声转发干扰效果,然后进行了仿真实验.理论分析和仿真结果表明,间歇采样灵巧噪声转发干扰产生的假目标幅度和距离分布更具随机性,并且可通过调节噪声时宽改变假目标覆盖距离范围和覆盖范围内的假目标密度,干扰方式更为灵活.In order to study how to effectively interfere with the linear frequency modulated pulse compression radar, this paper proposes interrupted-sampling smart noise repeater jamming. Firstly based on the characteristics of interference signal, the paper theoretically analyzes the effect of interrupted-sampling smart noise repeater jamming, and then carries out a simulation experiment. The theoretical analysis and simulation result show that the interference generated by interrupted-sampling smart noise repeater jamming makes the false targets distributed more randomly with more random amplitude, and that the target coverage and the density of false targets can be changed by adjusting the time width of noise, which makes the interference mode more flexible.
