摘要
针对云南天文台1.2米望远镜在激光测月中回波光子数太少的问题,将大气湍流效应考虑到激光测月中,研究了互相关和绝对差分两种跟踪算法的原理,并编写了算法程序,利用太阳数据验证了程序的正确性.给出了根据所采集的月面感兴趣区域的图像数据,用不同方法在不同条件下处理所得的大气波前整体倾斜信号,比较了算法的优劣。
Based on the fact that the returned photon numbers are few in Lunar Laser Ranging in Yunnan observatory 1.2 m telescope and the idea that effects of atmospheric turbulence should be considered, the two algorithms, absolute difference and cross correlation, are investigated. Programs are built and tested by sun data and are applied to lunar data. The atmospheric tip-tilt is computed in different conditions, the best algorithm and related conditions are selected.
