设计并研制了面向民航机场的能见度激光雷达,开展了连续6个月的观测试验,并与目前机场使用的大气透过率仪、 大气前向散射仪及人工观测结果进行了对比。结果表明：研制的DSL-V后向散射型能见度激光雷达达到了国际民航组织(ICAO)的技术要求, 能见度为0～600 m时探测误差小于11.3%(能见度绝对误差小于等于26 m)；能见度为600～1500 m时探测误差小于8.2%；能见度为1500～10000 m时探测误差小于14%。

A visibility lidar for the civil aviation airports is designed and developed. The observation experiments are carried out for six months continuously, and the results are compared with the atmospheric transmittance meter, atmospheric forward scattering meter and artificial observation results which are used in airports currently. Results show that the developed DSL-V backward scattering visibility lidar can meet the technical requirements of International Civil Aviation Organization (ICAO). When the visibility ranges from 0 to 600 m, the detection error is less than 11.3% (Absolute error of visibility is less than or equal to 26 m). When the visibility ranges from 600 m to 1500 m, the detection error is less than 8.2%. When the visibility ranges from 1500 m to 10000 m, the detection error is less than 14%.
