一种激光雷达指向的两级控制方法及工程实现
A Dual-Stage Control Method and Engineering Realization for LiDAR Pointing
摘要
Abstract
The key to LiDAR ranging for space targets lies in obtaining stable and reliable echoes,which requires the laser to lock onto and steadily point at the target.In general,pointing control and adjustment can be realized by means of satellite platform pointing control,turntables,internal swing mirrors inside lidar,and other methods,each with its own advantages and disadvantages.This paper proposes a two-stage pointing control method for lidar using a swing mirror and a turntable.On the one hand,it does not rely on satellite attitude control and can be decoupled from attitude control;on the other hand,it can give full play to the respective advantages of the turntable and the swing mirror.The turntable features a large pointing adjustment range and stable control,which is adopted for wide-range coarse pointing control.The swing mirror boasts fast response speed and flexible adjustment,serving for small-angle fine adjustment.This paper also puts forward engineering implementation methods such as initial guidance and optical reference calibration.Field test results show that after turntable coarse pointing and calibration compensation,the swing mirror can quickly lock onto the target and output ranging information.The method of realizing lidar ranging through two-stage control of the turntable and swing mirror is proven reasonable and feasible.关键词
