一种数据评价函数加权融合方法研究

Research on Data Appraisal Function Method of Weighted Fusion

对航行载体进行多传感器实时定位时，提出了一种数据评价函数加权融合方法。该方法利用量测值的偏差建立多传感器加权因子模型，进而计算出各传感器权值及最后融合结果。该方法能够最大限度的利用量测信息，有效解决GPS因小噪声干扰出现的定位不准确问题。

When carrying on the multi-sensor real-time locating to the navigation carrier, the paper proposed one data appraisal function weighting fusion method. This method establishes the multi-sensor weighting factor model using the measured value deviation, then calculates various sensors power value and the fusion result. This method can make maximum use of the gauging information to effectively solve the GPS localization problem which caused by small noise jamming.
