摘要
多传感器跟踪系统中因通信延迟常会出现无序量测现象,为了提高系统估计精度,采用直接更新法对状态进行更新估计,并针对噪声相关下含无序量测的多传感器系统,提出了矩阵加权最优信息融合状态估计算法,考虑了过程噪声和量测噪声的相关性以及局部估计的误差相关性.仿真计算验证了算法的有效性.
In multi-sensor tracking system,Out-Of-Sequence Measurement(OOSM)always occur due to communication delays.The system needs to update the OOSM in order to improve the precision.An optimal information fusion estimation weighted by matrix was presented for multi-sensor information fusion with OOSM,in which correlation between the process noise and measurement noise,local errors were considered.The simulation shows its effectiveness.
