摘要
介绍了一台用于大气气溶胶和云层测量的小型激光雷达系统,阐述了其系统结构和工作原理.对该激光雷达的水平大气回波信号进行了分析处理,得到了此系统的几何重叠因子及一段时间内的水平大气消光系数和对应的水平大气能见度等数据.
A compact aerosol lidar working with direct detection is introduced. It is used to measure atmospheric aerosols and clouds. The structure of this system and its working principle are illustrated. The horizontal received signal of this lidar is analyzed and processed in detail, and its geometric overlap factor is gotten. With a further processing, the horizontal atmospheric extinction coefficient and the corresponding horizontal atmospheric visibility are gained.
