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 threedimensional 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 0.85; the correlation coefficient of wind direction is 0.9; 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.
