摘　　要：为了保障航空器的安全起降,且大范围准确地监测机场能见度分布情况,采用误差分析方法,选取深圳宝安国际机场2022-01—2023-06激光雷达(LiDAR)观测数据,分别与人工观测主导能见度数据和自观系统计算的加权能见度数据进行了比对分析,初步验证了能见度激光雷达测量主导能见度的准确性与可靠性。结果表明,激光雷达观测数据与人工观测数据及自观系统观测数据的平均相对偏差分别为-5.30%和-5.45%,且激光雷达对大范围内能见度的早期变化更为敏感;降雨条件及主导能见度小于1500 m时,激光雷达观测结果的误差较大,需加以人工辅助观测,当主导能见度大于1500 m时,激光雷达可以代替人工输出主导能见度数据。该研究为基于能见度激光雷达的主导能见度测量实现机场业务化运行提供了依据和借鉴。To ensure the safe takeoff and landing of aircraft and accurately monitor the visibility distribution of airports on a large scale,the error analysis methodwas adopted,the light detection and ranging(LiDAR)observation data was compared with the manual prevailing visibility data and the weighted visibility data calculated by the self-viewing system of Shenzhen Baoan International Airport from 2022-01 to 2023-06.The accuracy and reliability of prevailing visibility measured by visibility LiDAR were preliminarily verified.The results show that the average relative deviations between LiDAR data and manual data and self-viewing system observation data are-5.30%and-5.45%,respectively.LiDAR is more sensitive to early changes in visibility over a wide range.When rainfall and the prevailing visibility is less than 1500 m,the error of the observation results of LiDAR is large,and manual observation is required.When the prevailing visibility is greater than 1500 m,LiDAR can replace the manual output of the prevailing visibility data.This study provides a basis and reference for airport business operation based on the prevailing visibility measurement of visibility LiDAR.
