摘要
介绍了一台直接探测的用于大气气溶胶测量的离轴激光雷达系统,分别从理论计算和实验测量两方面给出了该激光雷达系统中几何重叠因子的求解方法。结果显示,实验法所得几何重叠因子随距离的分布曲线和理论计算所得结果基本吻合,且实验法所得系统几何重叠因子随距离的分布曲线随日期基本不变,说明所介绍的用于求解系统几何重叠因子的实验方法是可行的。
An abaxial lidar system, working with immediate detection is introduced, which is used to measure the atmospheric aerosols. The working principles and structure of this system are illustrated. The geometric overlap factors were calculated both by theoretical and experimental methods. The final result shows that the distribution curve of the geometric overlap factor chaging as the distance fits well with the one obtained with theoretical methed. It is concluded that the experimental methed is correct and stable.
