- W4320515148 abstract "为实现星敏感器光信号的高精度标定需求，提出了一种具有空间背景光的星敏感器地面标定系统，解决了空间背景光对星敏感器光信号定标精度的影响，提高了星敏感器的标定精度.对空间背景光对星敏感器标定精度的影响进行分析，给出了具有空间背景光的星模拟器实现方案，设计了能同时模拟空间背景光和星点位置信息的星模拟器光学系统.结果表明，该系统全视场相对畸变小于0.01%，MTF在80lp·mm<sup>-1</sup>处大于0.5，达到了高精度指标要求.设计了一套空间背景光系统，通过对电流和可变光阑的控制，实现了亮度2<sup>6</sup>倍变化.提出了一种基于像差补偿的星点位置修正方法，并给出了修正模型.利用徕卡T6100经纬仪和照度计，分别对星模拟器所在的星点位置误差和空间背景光亮度进行测试.结果表明，空间背景光亮度可实现2<sup>6</sup>倍调整，在最高能量和最低能量下星模拟器星点位置误差精度<10，满足星敏感器地面标定要求." @default.
