摘 要: 针对日益恶化的空间轨道环境,为了航天器的在轨安全,研究了空间飞行器的碰撞预警问题。借鉴碰撞概率的思想,提出一套目标航天器与空间障碍物碰撞预警的新方法。这种方法利用一种简单、快速的轨道预报方法,并结合碰撞概率的思想,将目标航天器在空间的危险度进行分级量化,进而实施相应的预警策略来实现避碰,提高了目标航天器和空间障碍物碰撞预警的精确性和有效性,最后利用Matlab中的图形用户界面(graphical user interface, GUI)实现了整个预警过程。
关 键 词: 航空、航天科学技术基础学科;避碰;碰撞概率;预警;轨道预测;空间障碍物

Abstract: As the total number of orbital objects increase rapidly, it is now necessary to establish certain maneuver for the spacecraft to avoid collision. This paper dealt with the collision avoidance for spacecraft. A new early warning method was developed. The method was based on calculation of collision probability and orbit prediction. The method combined a simple method of orbit prediction with newly developed collision probability method, which could take advantage of both methods and quantify the risk degree that the spacecraft faced in outer space, thereby increasing accuracy and effectiveness of the collision early warning. Finally, the whole early warning process was realized by use of the graphical user interface (GUI) in Matlab.
Key words: basic subject of aeronautics and astronautics science and technology; collision avoidance; collision probability; early warning; orbit prediction; space obstacle
