摘　　要：空间失效航天器与空间碎片与正常运行的航天器发生碰撞会产生严重的后果,其不能提供自身的姿轨信息,可能会有翻滚等复杂运动状态,使空间操作的安全性受到威胁。以空间翻滚目标为研究对象,由相关任务带来的目标识别以及运动估计问题,引入了位姿耦合建模方法,推导了空间翻滚目标位姿耦合形式的对偶牛顿——欧拉方程,对翻滚目标的耦合性、运动特征进行分析,并以在轨翻滚目标为例仿真归纳了各类翻滚目标的主要运动形式。根据分析,空间翻滚目标的姿态运动可分为3类,并且根据其运动特征可以反推其质量特性,这对空间目标运动的识别与参数估计拥有重要参考意义。This paper take space tumbling target is the research object. In order to solve the recognition and motion estimation problem caused by related tasks, the pose-coupled modeling method is introduced and the dual Newton-Euler equation of space tumbling target is deduced. Tumbling target's movement characteristics is analyzed, and example simulations of all kinds of tumbling targets of the main form of movement are made as well. The result shows that there are three types of them and we can deduce the quality characteristics, which has important reference significance to the recognition and estimation of the unknown space targets.
