卫星激光测距是目前空间大地测量的主要手段之一,在地球动力学和大地测量学等领域有广泛的应用。云南天文台即将开展非合作目标分光路激光测距试验,即激光接收和发射光路系统分别由相邻较近的两台望远镜完成。针对分光路非合作目标激光测距系统,提出了一种非合作目标分光路激光测距中测距值的确定方法,并给出了相应的计算公式,为分光路激光测距数据处理提供参考。

The Satellite Laser Ranging(SLR) is currently one of main approaches in space-to-earth distance measurements,and it is widely applied in geodynamics and geodesy.An SLR experiment with non-corrperative target(s) will be carried out in the Yunnan Observatory.In such an experiment laser emitting and receiving are through two different telescopes adjacent to each other.Here we introduce a method of determining the range for such an SLR system,and give corresponding computing formulae,which could be references for data processing in SLR with separate optical paths.
