摘　　要：利用天文测光方法研究了地球同步轨道卫星可见光波段的反射光变特性.以三轴稳定地球同步轨道通讯卫星为研究样本,进行了可见光波段的光学非高分辨成像观测,并使用天文标准星进行定标.基于相位角序列的测光观测数据表明:在大相位角区域卫星光变曲线分布与漫反射光照数学模型计算结果有很好的一致性,以卫星主体和太阳能电池板的漫反射效应为主;而在小相位角区域与漫反射模型计算结果有明显的差异,为卫星的太阳帆板镜面反射效应影响所致.Astronomical photometry is employed to study reflection optical characteristics of geosynchronous earth orbit （GEO） satellites. Unresolved observations for the 3-axis stabilization GEO sample are carried out in visual band,and flux calibration is made with astronomical standard stars. Data were reduced and analyzed by using standard astronomical image processing software. Theoretical models of optical diffuse reflection characteristics are calculated. The deviation between the observations and theoretical models in large phase angle is small,dominated by diffuse reflection of satellite body and solar panels. And in the small phase angle the deviation is distinct,dominated by mirror reflection of solar panels.
