基于LMMSE估计的多传感器目标航迹融合

LMMSE estimation based multisensor track fusion

介绍一种基于线性最小均方差 ( LMMSE)估计的多传感器目标航迹融合方法。这种方法适于分布式多传感器目标跟踪系统 ,它具有 LMMSE估计器的许多优点。同时 ,由于它考虑了因公共的目标动态过程噪声引起的估计误差的非独立性的影响 ,因此 ,它比基于独立性假设的方法更精确。

Fusion of associated target tracks from multiple sensors based on LMMSE estimation is presented in this paper. It can be best used in distributed multisensor target tracking systems, which takes many advantages of LMMSE estimators. In addition, the effect of state dependence of the associated targets due to their common process noise on fusion error is taken into account in modeling. It therefore should be more accurate than approaches based on state independence assumption.
