According to the low accuracy of voltage driven radiation algorithm result, variance calibration method was used to analyze the errors between the average value and voltage driven radiation algorithm result, then give the data compensation. This paper gives the corresponding theoretical analysis and the experimental data. The results show that the variance of calibration method can effectively compensate the low accuracy of voltage driven radiation algorithm result and provide the effective reference for the later high frequency radiated interference's estimation and the diagnosis work.
