摘　　要：Galion激光雷达是应用第二代技术的激光雷达设备,具备对全天空、全角度的扫描能力,目前是市场上唯一的三维扫描设备。本文利用深圳356 m梯度塔与锡林浩特100 m梯度塔的观测数据分析了Galion激光雷达的探测性能,并得出以下结论:PPI模式下,深圳激光雷达与测风塔测得风速相关系数为0.85,风向相关系数为0.9;锡林浩特激光雷达与测风塔测得风速相关系数为0.9,风向相关系数为0.95;此外,雷达在各个角度探测的结果相关性都较好,说明激光雷达在PPI模式下具有很好的探测性能。The Galion lidar is a lidar equipment using the second generation technology.It has the ability to scan all sky and all angles.At present,it is the only three-dimensional scanning equipment on the market.Based on the observation data of Shenzhen 356 m gradient tower and Xilinhot 100 m gradient tower,this paper analyzes the detection performance of Galion Lidar and draws the following conclusions:in PPI mode,the correlation coefficient of wind speed measured by the Galion lidar and gradient tower in Shenzhen is O.85;the correlation coefficient of wind direction is O.9;the correlation coefficient of wind speed and wind direction measured by the Galion lidar and gradient tower in Xilinhot is 0.9 and 0.95,respectively;in addition,the correlation of lidar detection results at all angles is good,indicating that the lidar has good detection performance in PPI mode.
