| 摘要: |
| 首先提出了一种测量目标辐射源脉冲到达时间和到达方向实现固定单站对运动辐射源进行无源定位的算法，该算法克服了EKF(扩展卡尔曼滤波)算法的一些缺点。另外给出了两种将该算法和卡尔曼滤波算法结合的改进方法，可以获得更优的定位效果。计算机仿真结果证明了上述两种方法是正确的。 |

| Abstract: |
| An algorithm for the moving emitter passive location and tracking based on TOA and DOA measurements by a single fixed station is given. This algorithm has some great advantages over the extended Kalman filter (EKF). Furthermore，the two improved methods which combine this algorithm with Kalman filter can obtain better location performance. And the results of the computer simulation prove that they're good methods. |
