摘　　要：为确保辐射测量精度,需要对红外辐射测量系统进行标定。在分析红外辐射测量系统工作原理的基础上,提出了内、外标定相结合的标定方法,区别于传统的标定方法,不再把测量系统当作"黑盒子",而是对其内部分解进行分步标定,通过理论推导给出了内外标定方法计算公式。实验验证表明,该方法的标定精度与传统的全孔径黑体标定方法基本一致,两者之间的相对误差在1%以内,但该方法对外置大孔径面源黑体温度范围要求比较低,降低了黑体的研制难度和成本。To ensure the accuracy of radiation measurement, it is necessary to calibrate the infrared radiation measurement system. Based on the analysis of working principle of infrared radiation measurement system, a calibration method combined internal and external calibration was proposed which was different from the traditional calibration method. It separated measurement system to calibration step- by-step, no longer as a whole ＂black box＂. Through theoretical derivation the internal and external calibration calculated formula was given. The experiments show that the calibration accuracy of the new method is accord with traditional full-aperture blackbody calibration method, within 1% relative error. This method reduces the requirements of temperature range of the external full-aperture blackbody, also reduces the development difficulty and cost of blackbody.
