基于天基光学短弧观测的GEO卫星分选

摘要

A novel method for screening of GEO objects through space-based optical short arc observations is proposed in this paper. The concepts of measurement attributes and admissible regions are introduced. A plane of admissible region is established to make use of effective short-arc observations, taking the distance of the observer to the target and variation ratio as its axes. Considering the characteristics of GEO objects, the method screens GEO objects through energy constraints and hypothesis of orbit elements. Simulation indicates that the method can screen GEO objects with short arc observations even in cases of lack of accurate information in space objects databases.%提出一种基于天基光学短弧观测数据集分选同步带目标的方法,引入测量属性和约束域概念.为利用短孤观测数据中的有效信息,以目标和平台的相对距离和距离变化率为坐标轴,建立约束域平面.利用GEO(地球同步轨道)目标运动特点,通过能量约束和假设轨道反演2种方法,从多个目标轨迹中分选出GEO目标.仿真结果表明,该算法可在数据库不完备的条件下通过短弧观测分选出同步轨道卫星.
