  • In order to solve the difficulty of detecting three-dimension wind field oblique upper of a scanning wind lidar, a method of wind field inversion was provided based on multi-point regular acquiring, four-beam packet calculating and multi-area merging. To verify the validity of this method, a target with controllable velocity was studied and synthetic velocity was compared with the velocity in control. The result indicates that the method is feasible and effective. The accuracy test was designed to calculate the actual wind field within 400 m. Measurement data from lidar were compared with that from three-axis anemometer. The results indicate that the wind direction accuracy is better than 5, and the wind speed accuracy is better than 2 m/s, which is enough to describe the wind field of detecting area accurately.
