【Abstract】 Spatial object infrared radiation feature measurement experiment is the direct and only means for acquiring infraredradiation features of spatial objects.The composition and key technologies of the developed ground-based spatial object infrared radiation feature measurement system are introduced.An infrared monochromatic collimator and an extended-area blackbody are used to implement the spectral calibration and radiation calibration of the ground-based measurement system,respectively,and atmospheric parameter observation devices are used to realize the atmosphere transmission correction between the spatial object and the ground-based measurement system.The radiation calibration precision and the object radiation measurement precision for the ground-based infrared radiation measurement system are analyzed deeply.The radiation calibration precisions for the midwave and longwave infrared measurement systems are 6.9% and 4.8%,respectively;and the object radiation measurement precisions for them are 23.7% and 23.2%,respectively.The ground-based measurement system was used to perform infrared radiation measurement experiments on the international space station(ISS);and the midwave and longwave infrared radiation measurement results of the ISS are given.更多还原
