摘　　要：红外辐射标定是红外辐射特性测量的精度基准。针对外场条件下红外辐射标定精度影响因素多的情况,开展外场红外辐射标定方法研究。首先介绍适应于外场条件的三类红外辐射标定方法及其优缺点,然后分析黑体标定温度的影响、环境温度对黑体实际辐射的影响、程辐射与地表辐射的影响等三大影响外场标定精度的因素,最后给出各影响因素的解决方法并通过实验进行验证。实验结果表明,采用文中标定方法可将辐射测量误差由27.8%降低至11.4%。The infrared radiation calibration is the precision reference of infrared radiation characteristics. According to infrared radiation outfield calibration factors, this paper carries out the research on calibration methods of infrared radiation. Firstly, three infrared radiation calibration methods and their advantages and disadvantages are introduced, and then the influences of blackbody temperature, environment temperature, optic radiation and surface radiation are analyzed. Finally, each factor solution is given and validated by the experiment. The experiment results show that the radiation measurement error can be reduced from 27.8% to 11.4%.
