Satellite retroreflector is used as laser ranging cooperative target to improve the intensity of reflected beam, which has close relationship with processing parameters of the retroreflector.

卫星角反射器作为激光测距系统中的合作目标, 其主要作用在于提高地面接收机范围内反射光束的能量密度。

Murphy's primary method will be something called "laser ranging."Light from a laser fired from the Earth could hit a reflector on the surface of the moonbounce back.

Murphy的基本方法将是"激光测距"，从地球上发出的激光打射到设在月球表面的反射器上，反射回地球。

The ships are fitted with C- and S-band monopulse tracking radar, Cinetheodolite laser ranging and tracking system, velocimetry system, and onboard computers to track and control the spacecraft.

测量船配备有C-和 S-波段的单脉冲跟踪雷达，激光测距经纬仪和跟踪系统，测速系统和舰载计算机去跟踪和控制宇宙飞船。
