单传感器的数据融合及有效性分析

Single sensor data fusion and analysis of effectiveness

指出了一种单传感器数据融合方法所存在的缺陷,在修正了这个缺陷的基础之上,进一步从理论上证明了在单传感器系统中,当样本观测值一定时,分组数据融合的估计效果优于传统的单组算术平均的估计效果。实例的数据分析也验证了上述结论的正确性。

A mistake of the single sensor data fusion is analyzed. The following conclusion is proved theoretically further. In the system of the single sensor,when observed values of sample are given,the method of data fusion to divide into groups is superior to the estimation result of single group’s arithmetic average. Actual data analysis shows the correction of the conclusion.
