摘　　要：在电子对抗领域中,无源定位已经得到人们的高度重视.本文探讨了一种利用辐射源信号到达方向角度信息和多普勒频率信息,实现固定单站对机动目标进行无源定位与跟踪的新方法.该方法充分利用了辐射源信号测量值的空域和频域变化量信息.本文讨论了它的若干技术问题、定位原理与算法.通过计算机仿真,验证了该方法的正确性与有效性.Passive location is being paid more and more attention in the electronic warfare（EW） field. The algorithm for passive location of maneuvering target by single station is discussed using the direction angle of arrival and Doppler frequency of the emitter. This algorithm takes full advantage of the spatial and frequency domain changing information of the measurements from the emitter. Some concerned issues, such as technical problems, principle and algorithm are discussed. With the help of computer simulation, the method is proved to be correct and effective.
