An overview ofthe radiometric calibration facility for infrared sensors

Large-scale calibration facilities were developed in many countries and they played important roles in the space exploration. This paper reviews some representative calibration facilities and their performances. Some key technologies related to these mechanisms are discussed, such as the design strategy and the design of the calibration optical system and structures, as well as the selection of radiometric sources. The development of the calibration facility in China is suggested, including some crucial issues to be investigated, which may serve as a technical reference for the development of the radiometric calibration in China.
