%X In calibration of a infrared spectrum radiometer, we calibrate an infrared radiometer by measuring on various temperatures of the blackbody in order to reduce error. For the radiometer measuring weak radiation, the background temperature has unavoidable effect on calibration. The methods of calibration by measuring the standard blackbody at different temperature was discussed. The experimentation results were analysed, and the effect of the background temperature on the calibration result was given.
