摘　　要：提出了一种基于EKF（Extended Kalman Filter）单星对地面无线电辐射源的定位方法．该方法能够解决基于干涉仪测向的定位处理中存在的模糊问题，从而可通过增加测向基线长度提高测向的定位精度。A method of single satellite locates electronic emitter based on Extended Kalman Filter is proposed in this paper. It can solve location ambiguity which is based on interferometer direction, therefore we can simply improve the accuracy of direction by increasing the baseline length.

关 键 词：卫星定位 相位 模糊 EKF
