摘要: 高重复频率激光器是kHz卫星激光测距系统的重要组成部分,提高激光发射频率可以有效地获得更多的观测数据,这是当今卫星激光测距领域的发展方向。针对武汉卫星观测站进行的kHz激光测距实验,介绍了kHz激光器的工作过程和原理,分析了影响高重复频率回波探测的因素。实验结果表明:对实验过程中所观测到的中低轨卫星,观测数据量提高了1~2个数量级,观测精度也有所提高。Abstract: The kHz satellite laser ranging (SLR) system can effectively obtain a large quantity of observation data by laser emission at high repetition rate. Based on the kHz experiment at the Wuhan SLR station, the paper introduces the ranging method and the operation principle of kHz laser, and analyzes the influencing factors of echo detection in high repetition frequency. The experimental results show that the data quantity is increased by 1 to 2 orders of magnitude, and the single measurement precision is improved for the medium earth orbit and low earth orbit satellite tracking observations.
