摘　　要：随着数字射频存储器(DRFM)技术的不断发展与成熟,该技术越来越多地应用于雷达干扰领域。提出一种针对线性调频信号脉冲压缩体制雷达的基于DRFM技术的距离波门拖曳干扰方法。本方法采用脉冲内式样移频调制转发、脉冲间正余弦叠加随机量的二次移频调制方法实现。并对其进行了Matlab仿真分析,证明了该方法的有效性。With the continuous development and maturity,digital radio frequency memory(DRFM)technique is increasingly popular to be applied to the field of radar jamming.This paper proposes a range gate pull off(RGPO)jamming method based on DRFM technique aiming at linear frequency modulation signal pulse compression radar.The proposed method is accomplished by intra-pulse pattern frequency-shift modulation repeater and secondary frequency-shift modulation of inter-pulse sine/cosine add random quantity,and Matlab simulation analysis is performed to validate the effectiveness of the method.
