摘要:

为了提高卫星定量化应用水平,需要进一步提高卫星光学载荷的定标精度。当前载荷定标依然以地面定标为主,为了缩小在轨与地面因环境因素引起的定标误差,需要模拟在轨真实环境进行定标试验。针对当前发展迅速的光学载荷真空定标技术,描述了国内外发展现状,阐明了真空定标专业的概念与分类,并结合真空定标技术的应用现状,分析了真空光谱定标和辐射定标的系统组成和技术难点,最后就未来我国真空定标技术的发展提出了建议与展望。

Abstract:

The precision of satellite optical load calibration must be enhanced to boost the quantitative application of the satellite. Currently calibration on earth is the most used method. In order to reduce the error caused by the environment between earth and space, the simulation of the real on-orbit environment  is needed to carry out the calibration test. In view of the rapid development of vacuum calibration technology of satellite optical load, the development status at home and abroad in detail is described, and the concept and class of vacuum calibration are illuminated. In addition, according to the application of vacuum calibration technology, the system components and technical difficulties of vacuum spectral calibration and radiation calibration are analyzed. At last, expectation and suggestions for the development of vacuum calibration technology is presented.

Key words: satellite, optical load, vacuum calibration, radiation calibration
