| 摘 要： | 对仅有方位量测的被动目标跟踪问题建立了一种拟线性时变模型，利用增广卡尔曼滤波讨论了可测性，给出了它的滤波解、离散系统及其解析解，本模型不需要任何初始估计；对算法进行了蒙特卡罗仿真试验，给出了不同噪音水平下4种典型态势的仿真结果。

PSEUDO-LINEAR ESTIMATOR FOR BEARINGS-ONLY SINGLE-TARGET LOCALIZATIONA AND TRACKING |
| |
| Abstract: | A pseudo linear time dependent model for passive single larget localization and tracking using bearings only measurements has been given, base in extended kalman filter. Its observability and solution of filtering were discussed. Both discrete time system and analytic solution were addressed. The model does not require any initial estimate. The algorithm is tested in Monte carlo simulations an dits results are presented for four typical scenarios at various noise levels. |
