摘　　要：地月激光测距是"天琴计划"0123技术路线图中的第"0"步,为实现引力波探测卫星的高精度定轨及相关科学研究,本文开展了月球激光测距分析与实验研究,分析系统探测能力和测距精度。中山大学天琴计划激光测距台站(以下简称"天琴台站")采用1.2 m口径激光测距望远镜,激光波长1064 nm,激光能量320mJ,激光重复频率100 Hz,激光脉宽80 ps,首次采用2×2多元阵列超导探测器进行月球激光测距。天琴台站于2019年6月8日(农历初六)晚首次获得来自Apollo 15角反射器阵列有效回波信号4组,随后于2019年11月7日(农历十一)晚成功接收到来自月面全部5个激光角反射器阵列的有效回波信号,测距精度达到cm量级,标致着天琴台站已经具备常规月球激光测距能力。In order to serve the needs of precise orbit determination for the three satellites of the Tianqin Project,lunar laser ranging analysis and experimental research were carried out.The TianQin laser ranging station in Sun Yat-sen University uses a 1.2 m diameter laser ranging telescope with a laser wavelength of 1064 nm,a laser energy of 320 mJ,a laser repetition frequency of 100 Hz,and a laser pulse width of 80 ps.It also uses a 2×2 multi-element array superconducting detector for lunar laser ranging for the first time.After two years of lunar laser ranging experiments,on the evening of June 8,2019(the sixth day of the lunar calendar),four sets of effective echo signals from the Apollo 15 corner reflector array were obtained for the first time,and then on November 7,2019(the tenth day of the lunar calendar),successfully received effective echo signals from all 5 laser retro-reflector arrays on the lunar surface,with cm level precision,indicating that the TianQin laser ranging station has acquired regular lunar laser ranging capability.
