卫星激光测距系统控制分系统设计及实现方法

卫星激光测距系统是一套集光、机、电为一体的精密复杂系统。控制分系统主要通过精确控制激光器分系统、望远镜分系统、折轴光学系统实现测距信号的发射、接收和测距数据处理。是保证系统具有高自动化程度和高测距成功率的关键技术。使用 FPGA 设计制作控制信号板，产生激光点火信号和距离门信号，实现精确控制激光器、单光子雪崩二极管和时间计数器。 本文对系统的整个工作流程进行了仔细分析，设计出软件的各个功能模块。分别对 1m 望远镜、 激光器做了控制试验，用真实卫星白天测距数据做了数据处理试验，得到了很好的效果。

Design and Implementation Method of Main Control System in Satellite Laser Ranging

Satellite Laser Ranging system is an accurate and complicated system integrated with light, mechanism and electric. Main control system controls the emission, reception of ranging signal and processes the ranging data through laser system, telescope system and optics system. It is the key technique to secure the high automation and high success odds of the satellite laser ranging system. It uses FPGA to design the signal control board, generates the laser trigger signal and range gate signal, to control Laser, SPAD and event timer accurately. The paper designs the function modules through analyzing the whole working process of the system in detail. The controlling test to 1 meter telescope and laser, the data process test with the real daylight satellite ranging data, all show good effects.
