天基光学空间目标监视信息处理技术分析

Information Processing Technology in Optical Space-based Space Surveillance

SBV是目前已成功应用于空间目标监视的典型天基光学传感器,通过被动探测空间目标反射的太阳光线辐射,完成对其探测、捕获和跟踪,并收集各种空间目标的观测数据。本文首先对SBV特点和性能进行介绍,然后以其为系统原型对天基光学空间目标监视信息处理流程和特点进行分析,提取相应关键技术,包括目标检测与恒星提取、编目维护与更新以及目标亮度特性分析等,并就其技术难点和发展趋势进行探讨。

Space-based Visible （SBV） was the typical space-based optical sensor which was used for space surveillance successfully, Via a visible sensor installed on a satellite to detect the sunlight radiation reflected by space objects, SBV could achieve the goals of detecting, capturing and tracking these objects. At the same time, abundant observation data of various space objects were collected. In this paper, the characters and performance of SBV were introduced firstly, Then, taking the SBV as the prototype system, the information flow and technology characters in optical space-based space surveillance were outlined and analyzed, and the corresponding key technologies were abstracted, including target and star detection, Resident Space Object （RSO） catalog maintenance and update, analysis of objects brightness characters. The technology choke point and future development directions were discussed finally.
