摘要
介绍了小口径便携式Mie散射激光雷达的系统结构、技术参数以及激光雷达信号处理的关键技术和处理方法。给出了测量结果,并与Vaisala公司能见度仪的测量结果进行了对比。这种Mie散射激光雷达具有结构紧凑、重量轻的特点,非常适合于进行能见度和大气消光特性时空分布和时间演变特性的研究。同时也可以进行车载或者结合扫描装置进行自动扫描监测,以获取感兴趣的区域颗粒物的时空分布。
The systematic structure and technical parameters of the compacted portable Mie lidar system are introduced. The key techniques and methods of lidar data processing are also presented.The experimental results are obtained and compared simultaneously with the visibility sensor of Vaisala.The lidar system is compacted and light weight and it can be used to the measurement of visibility,the profiles of extinction that can show the temporal and spatial distribution of aerosol;it can be used as mobile lidar and also be combined with scanning device through which can get the temporal and spatial distribution of aerosol in interesting area.
