【摘要】为了获取高精度的月面高程,需要对激光器的指向误差进行准确估计。月球轨道激光高度计(LOLA)在轨工作期间,由于月球昼夜温度相差较大,夜晚的激光指向相对白天存在很大偏移。首先建立光斑偏离接收视场中心时探测器接收能量的理论模型,并基于该模型分析光斑偏移量与相对接收能量的理论关系,进而提出一种基于光斑能量的激光指向误差的估算方法。随后,使用测绘轨道期间(12个月)LOLA经过Aestuum地区产生的能量数据,并将能量数据与估算方法相结合,估算出LOLA在月球夜晚时的激光指向误差在沿轨方向为140.62μrad,在垂轨方向为-413.17μrad,该结果与LOLA地球扫描实验和利用轨道交叉点处高程数据推导的结果基本一致。
