Surface-type infrared decoy is a typical countermeasure against infrared imaging guided missile. Its infrared radiation performance is an important technical indicator that determines the effectiveness of surface-source infrared decoy anti-missile combat. In this paper, the error factors of the airfield measurements of infrared radiation performances are analyzed. In the key process of radiation calibration, measure distance selection, image elements selection and atmospheric attenuation correction, some efficient methods and control measures in calibration and testing process are presented. The measurement accuracy of infrared radiation is improved from 9.8% to 21.7% of the traditional method to 5.4% to 10.1%. Thus, the effective means are provided in airfield measurements of infrared radiation performances.
