介绍一种利用运动目标图象傅里叶谱位相信息实现对目标定位的新方法，该方法具有较高定位精度，且不受运动目标姿态改变的影响。文中介绍原理、给出计算机仿真和实验测量结果，并讨论实际应用的可行性 A new method to locate the target using the information of the Fourier spectrum of the moving target image is introduced. The method has high positioning accuracy and is not affected by the change of the attitude of the moving target. The paper introduces the principle, gives the computer simulation and experimental measurement results, and discusses the feasibility of practical application
