摘　　要： 为适应空间光学遥感技术的快速发展及对空间光学遥感器需求的不断增长,在追求高空间分辨率、高光谱分辨率、高辐射分辨率性能及轻量化的同时,必须考虑空间光学遥感器对恶劣的发射运载力学环境及在轨真空热环境的适应性问题。本文概述了国内外空间光学遥感器环境适应性设计的现状与进展,阐述了空间环境因素对空间光学遥感器性能的影响,尤其是在力学及真空热环境作用下的环境效应,探讨了环境效应的作用机理。在对任务需求和环境效应分析的基础上,提出了空间光学遥感器环境适应性设计的要求、准则以及适应性设计要点。提出在空间光学遥感器设计的早期设计阶段,应统筹考虑对未来可能遇到的各种环境的适应性问题,并开展以质量特性、动力学特性及热光学特性为主的适应性设计分析迭代。在实施阶段,需进行相应的特征试验以及环境模拟试验,实地考核空间光学遥感器的力学及热光学特性以及在各种模拟环境条件下功能和性能的有效性和正确性,确保对未来各种恶劣环境条件的适应性。本文对设计分析迭代过程中以及试验过程中对环境适应性的评价方法及其相关的地面试验内容和方法也进行了论述。 In order to meet the requirements of the exploration to the earth and planets, the adaptability of space remote sensors to the rigor launching and space vacuum thermal environments must be considered in design, while we seek a fine space remote sensor with high spatial resolution, high spectral resolution, high radiation resolution, super imaging quality and light weights. This paper summarizes the present state of environment adaptability design and the influence of mechanics and vacuum thermal environments on the performance of space remote sensors, and researches the mechanism of environment effect and the key points of environment adaptability design. Then, it presents the demands, criterion, and key points for environment adaptability design of the space optical remote sensors based on the working mission. Furthermore, it suggests that the environment adaptability factors must be taken into account comprehensively in the early design phase and the mass characters, dynamical behaviors and thermal optical characters of space optical remote sensors should be also considered in the iteration course of design and analysis. During the production engineering stage, environment adaptability test should be carried out for assessing practice dynamical behaviors and thermal optical characters of products and for verifying the performance of space optical remote sensor to insure sensor＇s adaptability against rigor and thermal environments. Moreover, the evaluation methods of environment adaptability design and related test contents are also described in this paper.
