Abstract: Due to data fusion of multi-sensor experiment on some characteristic index，a new fusion method is proposed based on the principle component analysis.The method views the measured data of every sensor as a variant.After defining each principle components for the collectivity，the synthesis support degrees of all sensors are given according to the compound relationship between the measured value and the principle component.The formula of data fusion is obtained.The applied example proves that the method is both effective and accurate.
