摘要	In order to enhance the efficiency of infrared radiation calibration, a simple calibration method was brought forward. First, the radiation calibration model comprising integral time was put forward. Through the relation between integral time and cell's response gray in company with the relation between Blackbody's radiation luminance and cell's response gray, the concrete form of radiation calibration model was confirmed, and physics meaning of parameters in the formula were introduced. The radiation calibration experiments at different environmental temperature were processed and the changes of the unknown parameters with environmental temperature were plotted. The experiment results validate the radiation calibration model. A simple method for radiation calibration basing the model was brought forward, choosing two calibration points with the help of unitary linear regression method and collecting the two calibration points at two typical integral times, then the unknown parameters in the radiation calibration model were calculated through these four figures. Finally, comparison between the calibration data caught by calculating employing the model and actual calibration data caught by calibrating were took on. Experimental results indicate that the error between calculating and calibrating is small than 1%. The radiation calibration model is correct and the calibration efficiency could be boosted greatly.
