摘要
激光信号在大气传输过程中,极易受到雨雪等天气的影响。该文主要研究雨雪对激光传输的衰减特性。基于Mie散射理论,对M-P和Joss雨滴模型进行Matlab仿真,分析激光在雨雪中传输的关系,得到激光随降雨量、降雪量衰减的变化规律,进一步得到激光雷达最大探测距离随降雨量、降雪量变换的关系。
In the process of laser signal transmission in the atmosphere,it is easy to be affected by rain and snow. The attenuation characteristics of rain and snow on laser transmission are studied in this paper.Based on the Mie scattering theory,the M-P and Joss raindrop models are simulated by Matlab,and the relationship between laser propagation in rain and snow is analyzed,and the variation of laser attenuation with rainfall is obtained. Furthermore,the relationship between the maximum detection range of lidar and rainfall is obtained.
