摘　　要：介绍了一种工程中应用的固定单站雷达的无源定位方法。利用数字波束形成技术和比幅测角,可以得到目标方位角。再利用信号到达时间差,可以得到目标和雷达站间的距离信息。最后,对本方法的定位精度进行了分析,并给出了计算机仿真结果。An applicable passive location algorithm of target based on single fixed- site illuminator of opportunity is introduced in this paper. The azimuth angle can be acquired using digital beam formation technique and the angle measuration by comparing amplitude. Based on Time Difference of Arrival（TDOA）, the distance between the target and the fader station is accessible. Finally, the accuray of location is analysed, and the computer simulation results are presented.
