摘　　要：近年来月球辐照度的地基观测实验不断增加,为了满足地基对月球辐射高精度、高频次的观测,需要设计高精度的月球自动跟踪系统进行跟踪实验。所设计跟踪系统通过月球位置算法获得月球的天顶角和方位角进行视月跟踪,然后采用以四象限探测器为核心器件的光电跟踪来精确跟踪月球。经外场跟踪实验验证,视月跟踪和光电跟踪相结合具有高精度的跟踪效果,跟踪精度在±0.2°以内,表明跟踪系统具有较高的准确性和可靠性。In recent years,the ground-based observation experiments of lunar irradiance have been increasing.In order to meet the high-precision and high-frequency observation of the lunar radiation on the ground,it is necessary to develop a high-precision lunar automatic tracking system for tracking experiments.The designed tracking system uses the lunar position algorithm to obtain the zenith angle and azimuth of the moon for apparent motion tracking,and then uses the photoelectric tracking with the four-quadrant detector as the core device to accurately track the moon.The external field tracking experiments have shown that the combination of apparent motion tracking and photoelectric tracking has high-precision tracking effect.The tracking accuracy is within±0.20°,indicating that the tracking system has high accuracy and reliability.
