摘　　要：月球用于卫星在轨辐射定标具有稳定性高、反射率光谱变化平缓、背景影响小、不受大气影响等优点。由于月球辐射受月相角、月天动平、日月距离等因素的影响,月球定标需要通过地面长期观测以建立高精度的月球辐射模型。为此,设计了一套地基月球光谱辐照度仪的自动跟踪系统。该系统利用月球位置算法获得月球的天顶角和方位角以实现初步跟踪,进而利用CCD相机拍摄月球图片进行图像处理以实现精确跟踪。室外跟踪观测实验表明,月球位置计算和图像处理跟踪相结合的跟踪方式具有较高的精确度,平均跟踪精度在0.04°以内,证明该月球跟踪系统具有准确性和可靠性。The moon has the advantages of high stability,gentle variation of reflectance spectra,low background influence,and being free from atmospheric effects when used for satellite in-orbit radiation calibration.As lunar radiation is affected by factors such as lunar phase angle,lunar alignment,and distance between the sun and the moon,lunar calibration necessitates long-term ground-based observation to establish a high-precision lunar radiation model.Therefore,an automatic tracking system for the ground-based lunar spectral irradiance meter was designed in this paper.The preliminary tracking for the system is achieved by calculating the zenith and azimuth angles of the moon using the lunar position algorithm,and then precise tracking is accomplished through image processing of the lunar images captured by a CCD camera.The outdoor tracking observation experiments show that,the tracking approach combining lunar position calculation and image processing tracking possesses relatively high precision,with an average tracking accuracy within 0.04°,validating the high accuracy and reliability of the lunar tracking system.
