地月第二拉格朗日点卫星激光测距技术研究

Study on Laser Ranging for Satellite on the Second Lagrange Point of Earth-Moon System

  • 摘要: 介绍了月球/中继星激光测距的科学意义、研究状况和发展趋势;研究了地月第二拉格朗日点(L2点)纯反射式激光测距技术和任务设计,主要包含单体大孔径激光角锥反射器的设计与研制,以及基于云南天文台1.2 m望远镜的月球/中继星激光测距系统研究。研究结果表明:采用单脉冲能量3 J和10 ns脉宽脉冲激光器,预期系统能接收到的单脉冲回波光电子数约为0.74,单光子测距精度优于1 m。

     

    Abstract: The background and scientific goals of lunar/relay-satellite laser ranging is introduced. The current status and development trends of laser ranging is presented. The mission design is discussed,mainly including the manufacture of a single 170-mm-aperture Corner-Cube Retroreflector(CCR)a the laser ranging system based on a 1.2-m telescope installed at the Kunming station of Yunnan Observatory. A pulse laser with pulse width of 10ns and pulse energy of 3 J is used. The received photon number of 0.74 is expected,and the ranging precision is better than 1 meter.
