摘　　要：单站无源定位避免了复杂的时间同步以及多个观测站之间的数据融合,有着广阔的应用前景。采用基于到达方向(DOA)与到达时间(TOA)测量信息可实现固定单站对运动辐射源的无源定位跟踪。讨论了EKF,MGEKF,MVEKF三种算法的原理,并通过MATLAB仿真说明了算法的有效性,以及MGEKF与MVEKF对定位性能的改善。Single observer passive localization and tracking system avoid time synchronization and data fusion, it can be widely used in the engineering field. The locating and tracking a moving emitter can be realized by a fixed observer based on the measurement of the direction of arrival（DOA） and the time of arrival（TOA）. The principle of the three algorithms is discussed which is EKF, modified gain EKF, and modified covariance EKF. The validity of the algorithms is approved from MATLAB simulation and the capability of passive location and tacking is improved by MGEKF and MVEKF.
