摘要: 针对目前多传感器数据融合过程中,传感器观测噪声不易确定,提出了一种基于LMS算法的多传感器自适应加权数据融合方法。该方法将传感器最优加权系数的求解,转化为估计值的均方误差性能表面的最优解搜索,通过加入自适应阶段,采用自适应最小均方误差(LMS)算法调整传感器加权系数。仿真结果表明该方法的有效性。

Abstract: For the optimal weighed fusion of multi-sensor data with the variance of the observation error is unknown and variant, this paper presents a new multi-sensor weighed data fusion method based on LMS (Leanest Mean Square) algorithm. This method converts the optimal weighed fusion of multi-sensor data to the optimal solution search on the performance surface of mean square error of estimated value. Adaptive LMS algorithm is applied to adjust the weighting coefficient of sensor. Simulation results show the effectiveness of this method.
