摘　　要：国外航天大国均建有大型辐射定标设备,并在空间探测技术研究中发挥着重要作用。文章介绍了国外典型的大型辐射定标设备及其技术指标,较系统地总结了这些设备的研制技术和经验,如定标光学系统设计、辐射源选择和机械结构设计等关键技术的设计思路和解决途径;针对我国现有的辐射定标技术与国外的差距,提出了今后发展的一些建议。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.
