摘要
MarkⅢ大气透射计用于测量红外干扰烟幕透过率时，为了保证测量结果的可靠性，需要首先对其进行标定．根据大气透射计的工作原理，介绍了仪器的标定方法．该方法采用目标辐射调制技术消除环境背景辐射等因素对测量结果的影响．引入修正系数，来修正实际目标测试时与标定时光谱辐射计所接收的辐射量的差别．
In order to ensure reliability of measurement results, it is needed to be calibrated before Mark Ⅲ radiometer is used to measure transmission of the infrared screening smoke. Based on the working principle of atmospheric transmissometer, the calibration method of the instrument is presented. The method is technique of target radiation modulation for discrimination of the background radiation. Correction factor is introduced to correct the difference between the factual object measurement result and the calibration result.
