| 中文摘要 |
| 对带相关观测噪声和未知噪声统计的多传感器系统, 用相关方法得到噪声统计在线估值器．在按分量标量加权线性最小方差最优信息融合准则下, 用现代时间序列分析方法, 基于滑动平均(moving average)新息模型的辨识, 提出了自校正解耦融合Wiener预报器．用动态误差系统分析(dynamic error system analysis)方法证明了自校正融合Wiener预报器收敛于最优融合Wiener预报器, 因而它具有渐近最优性．它的精度比每个局部自校正Wiener预报器精度都高．它的算法简单, 便于实时应用．一个目标跟踪系统的仿真例子说明了其有效性. |
| 英文摘要 |
| For the multisensor systems with correlated measurement noises and unknown noise statistics,the on-line noise statistics estimators are obtained by the correlation method．Under the linear minimum variance optimal information
fusion criterion weighted by scalars for components,by the modern time series analysis method,a self-tuning decoupled fusion Wiener predictor is presented based on the identification of the moving average(MA) innovation models．By using the dynamic error system analysis(DESA) method,it is proved that the self-tuning fusion Wiener predictor converges to the optimal fusion Wiener predictor,so that it has the asymptotic optimality．Its accuracy is higher than that of each local self-tuning Wiener predictor．Its algorithm is simple,and is suitable for real time applications．A simulation example for
a target tracking system shows its effectiveness. |
