摘　　要：利用测向——交叉定位法对组网雷达中的辐射源进行无源定位时,来自不同辐射源的信号交织在一起,形成两类虚假定位.为消除这些虚假定位,根据分布式干扰机的特点提出了一种新的定位算法:首先利用各干扰机中进行的初级信号分选和融合中心进行的融合分选识别去除第一类虚假定位;然后利用分选识别数据采用多点源定位方法对组网雷达进行定位.仿真试验结果证明,分布式干扰机对组网雷达的无源定位方法是一种有效的定位方法.A lot of interlaced signals from various radiant point make produce two kinds of false location point when DOA location method is used to passive location for radiant point of netted radar. A new location method is given based on the features of distributed jammers for clearing these false location points. Primary signal sorting processed in jammer and fusion signal sorting and identifying processed in fusion center are used to clear the first false location points. Then multi-location method is given to locate netted radar using the data of signal sorting and identifying. The result of simulation demonstrates that the method for locating netted radar is an effectual location method of passive location.
