利用中国科学院国家天文台兴隆天文台的施密特望远镜对地球同步轨道（GEO）卫星的CCD图像进行了多色测光观测。对数据进行了处理，并对结果进行了分析。对比4颗卫星的观测结果，可以看出，不同总线类型的对象的强度曲线和颜色指数存在显著差异。两个夜间观测到的单个物体的曲线具有较强的相似性。并对相关系数进行了评估，量化和验证了上述结论。结果表明，GEO卫星的测光特性可以作为目标特征识别的一种方法。通过将滤波器从10个减少到5个进行了进一步分析，以研究更少数量的这些滤波器是否可以产生相同的结果。结果表明，5种滤波器也能部分区分卫星，但区分度较低。今后将进行更多的观测，以便进一步研究和改进空间物体识别方法。(C)2016年空间研委会。爱思唯尔有限公司出版
Multicolor photometric observations of Geosynchronous Earth Orbit (GEO) satellites in the CCD image have been performed experimentally using the Schmidt telescope at Xing-long Observatory of National Astronomical Observatories, Chinese Academy of Sciences. The data have been reduced and the results have been analyzed. Compared the results of 4 satellites observed, it can be concluded that there are significant differences between the intensity curves and color indices of objects with different bus types. And the curves of single object observed during 2 nights have relatively strong similarity. The correlation coefficients are also evaluated, which quantify and verify the conclusion above. The results indicate that multicolor photometric characteristic of GEO satellites may be used as a method of object feature recognition. Further analysis by reducing the filters from 10 to 5 has been conducted to investigate whether a smaller number of these filters can produce the same result. The results show 5 filters also can partly distinguish satellites, but with less discrimination. More observations will be performed in order to further study and improve the method of space object identification in the future. (C) 2016 COSPAR. Published by Elsevier Ltd.
