The beam scanning and inversion method for detecting wind by lidar
Utilizing lidar to obtain the wind velocity along the line of sight by Doppler shift, then inverting these velocity vectors to real atmosphere wind group speed is a very important purpose of lidar. The technique which utilize a conical scanning manner known as velocity azimuth display based on single LDV system is described. The horizontal and vertical wind sect of the observed field can be gained by spatial analytic geometry's operation and analysis on vectors of the four orthogonal points on the scanning cone's vertical section.
