Beam Scanning and Inversion Method for Lidar Detecting Wind
Utilizing lidar to obtain the wind velocity along the line of sight by Doppler shift and then inverting these velocity vectors to real atmosphere wind group speed is a very important purpose of laser lidar. The technique of using a conical scanning manner known as velocity azimuth display based on single laser Doppler velocimetry (LDV) system is described. The horizontal and vertical wind sections of the observed field can be obtained by spatial analytic geometry operation and analysis based on the four orthogonal points vector which located on the scanning cone′s vertical section. Then inverting these vectors to the observed wind field.
