摘要: 本文提出理想激光雷达回波功率Pm与实际回波功率Pr的概念。用数值方法求得不同脉冲宽度、可变背景、可变β层及不同接收门宽情况下的Pr/Pm与高度关系。应用计算结果处理了部分探测数据,显示了北京上空气溶胶层和到50km分子散射的某些形式与特征。Abstract: Conception of ideal LIDAR received power Pm and real received power are suggested. By numerical calculation,relations of Pr/Pm with height under different laser pulse width,various background,β layer and receiving gate width are obtained.The results are applied in observational data analysis and results which show the feature of aerosol and molecule scattering up to 50km in Beijing.
