摘　　要：对前沿复制重复转发干扰、线性函数移频干扰进行了原理分析,提出了基于线性函数移频的前沿复制干扰,改进了传统的前沿复制和基于线性函数移频的全脉宽干扰的实现方式,并对3种干扰方式进行了仿真和对比,实现了超前相参压制的自卫干扰,对线性调频脉冲压缩雷达自卫干扰有一定的指导作用。This paper analyzes the theory of repeating jamming with front edge replication,frequency shift jamming with linear function,proposes the front edge replication jamming method based on linear function frequency shift,which improves the implement modes of traditional front edge replication jamming and full pulse width jamming based on linear function shift-frequency,and simulates and compares three methods,realizes the self-defense jamming with pre-coherent-suppression,which has definite guiding role to self-defense jamming of linear frequency modulation(LFM)pulse compression radar.
