Abstract: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.
