摘　　要：基于TLE(two-line element)编目库的数据,对中科院国家天台长春人卫站空间目标光电阵光学观测数据以及观测能力进行了初步分析。选用2017年9月1日～5日的观测数据作为样本,结果显示光电阵每天可以观测得到约3500个弧段,每个弧段平均弧长约40s。约83%的观测弧段,可与TLE编目库中的目标成功关联。最后利用TLE数据,对这些目标的轨道分布特性进行了分析。初步分析结果表明,光电阵具备较好的LEO目标的观测能力。This paper conducts preliminary analysis of the optical observation data collected by the electro-optical array of the Changchun Observatory,National Astronomical Observatories,CAS and the observation capability of Changchun Observatory based on the TLE catalog database.Research on the observation data from 1st to 5th in September 2017 shows that about 3,500 orbital arcs can be observed every day,and the average arc length is about 40 seconds;about 83% of observation arcs can be associated to TLE catalog objects.Then this paper utilizes the TLE data to analyze the orbital distribution of these observed objects.Results of the preliminary analysis show that the electro-optical sensor has excellent observation capacity for the space objects in LEO.
