摘要	To measure the mid-infrared total atmospheric transmittance in a field and to improve the measuring accuracy of infrared radiation of spatial objects, a measuring method based on standard infrared stars was discussed. A mathematical model based on Beer's law and Langley-Plot calibration principle was established, and an experimental system based on the ground-based optic-electric telescope with an aperture of 1.2 m was set up. Then, Quasi-real-time One-point Correction Method, Window-extracted Method and SNR Characteristic Curve were employed to reduce the effects of the non-uniformity of detectors and the diffusion imaging of stars on the measuring accuracy. Finally, the error of the measurement in the experiments was analyzed. Experiments and analysis show that the maximum measuring error of the infrared radiation illumination of spatial objects is 16.28%, and the theoretical measuring error of mid-infrared total atmospheric transmittance is 11.75%. The results indicate that the measuring method proposed in this pape has a smaller measuring error, the experimental system is adapt to observation missions in the field and it provides a new solution for measuring the infrared radiation of spatial objects. , 2015, Chinese Academy of Sciences.
