Abstract
宜居带行星探测研究是近年系外行星研究的热点领域之一, 探测太阳系附近的宜居行星对研究生命起源等具有重要意义, 成为系外行星探测的重要内容. 天基分布式合成孔径技术作为系外宜居行星探测的重要手段, 已经成为目前前沿光学技术研究的热点方向, 但是仍有诸多技术问题需解决. 本文从宜居行星搜寻计划的需求出发, 根据以迈克尔逊干涉成像为基础的天基分布式合成孔径系统技术原理, 介绍了国内外典型分布式合成孔径系统的技术发展, 重点分析了实现天基分布式干涉成像所需采用的控制系统和技术, 并阐述了解决高精度空间测距、高精度时间同步、多层级位相同步等关键问题的技术要点. 为未来大型柔性可重构空间望远系统的建造提供了参考.Keywords
