摘　　要：针对时差无源定位系统站间接收的微弱信号,采用相关处理来提取时差信息,提出对其中个别侦察站的转发式相干干扰方法,破坏站间相关处理的信号来源架构,造成相关失配,获取错误时差信息并造成定位偏差,最后验证了实验仿真。Aiming at weak signals received among the stations of passive time difference of arrival(TDOA)location system,this paper adopts the coherent processing to extract time difference information,puts forwards the coherent repeater jamming method to individual reconnaissance station,which can destroy the signal source framework of coherent processing among the stations,cause the coherent mismatch,obtain the wrong TDOA information and bring about positioning deviation,finally verifies the experiment simulation.

关 键 词：时差无源定位 相干干扰 相关处理
