介绍了非共轴激光雷达几何因子的物理意义,分别通过理论分析和试验测量给出了求解几何因子的方法。结合自行研制的CSY-1便携式能见度激光雷达,将两种方法得到的几何因子进行对比,讨论了系统参数对几何因子的影响,从而实现了对激光雷达系统优化设计的可能性。

The physical meaning of anti-coaxial lidar geometrical factor is introduced in this paper. The two methods of calculating lidar geometrical factor are presented. One is an analytical method, the other is an experimental method. The geometrical factor of CSY-1 portable visibility lidar is discussed, and then the two methods are compared. The influence of lidar system parameter is analyzed as well. The calculation and analysis results can be used for optimizing lidar system design.
