摘　　要：运用激光雷达方程和米散射理论,采取高度规格化的信号处理方法,对不同高度、不同浓度和厚度的云层的激光反射特性进行了分析和仿真,实现了对云层的高度和厚度的判断。文中的研究结果对利用激光雷达进行气象观测,保证发射场的航天器、制导武器安全升空,具有一定的参考价值。This paper analyzes and simulates the laser scattering character of cloud layer with different density and thickness in different height.It can be used to judge the height and thickness of cloud from the analysis of scattering signal.During the analysis,equation for lidar and theory for Mie scattering are used,and the method of height normalization is also present.Analysis result of the laser scattering character of cloud layer is the theoretical basis of meteorology observation with lidar.It can be used for blastoff of spacecraft and aircraft.
