摘　　要：定量分析了间歇采样转发干扰对线性调频脉冲压缩雷达的影响。首先,得到了间歇采样转发干扰经过匹配滤波器的输出响应。然后,研究了距离旁瓣抑制网络对间歇采样转发干扰信号的影响,旁瓣抑制网络对于频偏比绝对值小于0.5的假目标有功率上的正得益,而对频偏比绝对值大于0.5的假目标有功率上的负得益。最后通过编程计算和仿真实验验证了本文分析的正确性,该研究为雷达对抗干扰评估试验提供重要的理论支撑。The influence of interrupted-sampling and repeater jamming on LFM pulse compression radar is quantitatively analyzed in this paper. Firstly, the output response of interrupted-sampling and repeater jamming through matching filters is obtained. Secondly, the influence of distance sidelobe suppression network on interrupted-sampling and repeater jamming is researched. The sidelobe suppression network has some positive power benefit for false targets with frequency offset ratio absolute value of less than 0.5, and has a negative power profit for false targets with frequency offset ratio absolute value of more than 0.5. Finally, the correctness of the analysis is verified by programming calculation and simulation experiment. Important theoretical support are provided for radar jamming evaluation test.
