The invention provides a space target intention rapid identification method based on early warning information, and belongs to the technical field of space debris collision early warning and space threat early warning. According to the method, historical early warning information of a space target is utilized to analyze and extract possible features of orbit data, so that a feature database is obtained, and a mapping relation between the feature database and a target intention and a mapping relation between key features and the target intention are respectively established by combining a supervised classification algorithm twice. And finally, realizing intention recognition of real-time early warning information through the space target intention library. The method solves the problem that in an existing space target intention recognition method, manual recognition is low in timeliness and accuracy, and compared with the prior art, the method can complete accurate target intention recognition in real time in an on-orbit mode and can be better applied to task scenes such as space debris collision avoidance, satellite autonomous management and space threat early warning.
本发明提供了一种基于预警信息的空间目标意图快速识别方法,属于空间碎片碰撞预警、空间威胁预警技术领域。方法利用空间目标的历史预警信息分析提取轨道数据的可能特征,从而得到特征数据库,再两次结合有监督分类算法分别建立特征数据库与目标意图的映射关系、关键特征与目标意图的映射关系,最后通过空间目标意图库实现实时预警信息的意图识别。本发明解决了现有空间目标意图识别方法中,人工识别时效性和正确率低的问题,相较于现有技术,本发明能够在轨实时完成目标意图准确识别,能更好的应用于空间碎片碰撞规避、卫星自主管理、空间威胁预警等任务场景。
