An engineering model of a pulsed optical radar was developed for NASA to monitor continually the position of an astronaut on the lunar surface. The system tracks and measures range to a cooperative target (retroreflector) up to a distance of 700 m with a range accuracy of +/-1 m and an angular accuracy of +/-1 mrad. The system also directs a TV camera at the astronaut. An optical radar was used because it does not require the large complex antenna system and target reflector of conventional rf radars. The system design, which features GaAs injection laser, small retroreflector target, and silicon photodiode receiver, was directed toward providing a compact, rugged, lightweight system with high accuracy and low power consumption.
为美国国家航空航天局（NASA）开发了一种脉冲光学雷达工程模型，用于持续监测月球表面宇航员的位置。该系统可跟踪并测量到合作目标（后向反射器）的距离，最大距离可达700米，测距精度为±1米，角度精度为±1毫弧度。该系统还将一台电视摄像机对准宇航员。之所以使用光学雷达，是因为它不需要传统射频雷达那样庞大复杂的天线系统和目标反射器。该系统设计以砷化镓注入激光器、小型后向反射器目标和硅光电二极管接收器为特色，旨在提供一种紧凑、坚固、轻便且高精度、低功耗的系统。
