摘　　要：针对高分辨率光学遥感器(以下简称高分遥感器)恒温控制要求的不断提高,文章分析了传统热控技术的优势与不足,提出采用间接热控技术进行大口径高分遥感器恒温控制的设计方法,并结合某高分遥感器的热控要求、关键部件的热控设计方案,详细阐述了间接热控技术的技术特点与实现途径。仿真分析结果及试验数据表明,间接热控技术能够满足遥感器的恒温控制需求,可以实现高分遥感器光学系统及主要结构的恒温控制精度优于±0.3℃。AbstractBased on the increasingly strict objective of constant temperature control of HR optical remote sensors, the advantages and disadvantages of the common thermal control technology are discussed in this paper. And furthermore, a new thermal control method is put forward which uses the indirect thermal control technology （ITCT） in the thermal design of large scale HR optical instruments at the first time. An application of ITCT in a HR optical instrument for which the highly constant temperature control is required is introduced in details. The simulation of the design and the data of the experiment shows that the results of thermal control using ITCT can meet the objective precision. By optimization design of the ITCT, the precision of constant temperature control of the main structures and optics of the HR optical instrument can be better than ＆#177;0.3℃.
