摘　　要：本文结合北京气象局提供的陆基激光雷达信号数据,通过Mie散射理论算法提取有效参数,着重分析Backscatter co⁃efficient(后向散射系数)。通过MATLAB以及Excel软件实现对数据的批量整理和可视化分析,根据图像结果,结合某地区观测时间段内信号采集的实际气象情况进行对比分析,得到了符合现实情况的分析结果,验证了算法的合理性,为后期雷达数据处理、应用提供了数据处理基础。In this paper,the Backscatter coefficient(Backscatter coefficient)was emphatically analyzed by means of Mie scattering theory algorithm based on the land-based LIDAR signal data provided by Beijing Meteorological Bureau.Through MATLAB and Excel software to realize batch finishing and visual analysis of the data,according to the result of image,combining with the actual meteorological observation period signal acquisition in a given area situation analysis comparison,accord with the reality of the results of the analysis,the rationality of the proposed algorithm,for the application of radar data processing in the late provide the foundation data processing.
