Wind retrieval algorithm of Rayleigh Doppler lidar

open access: yesActa Physica Sinica, 2011
The wind measurement principle and the structure of Rayleigh Doppler lidar are introduced. The method for Fabry-Perot(FP) etalon transmission curve calibration is given. The problem is pointed out that to fit the transmission curve by using Lorentz or Voigt function may induce large error: the relative error would be up to 8% by Lorentz fitting ...

Real Time Turbulence Estimation Using Doppler Lidar Measurements

open access: yesEPJ Web of Conferences, 2016
A preliminary work on a new way to estimate atmospheric turbulence using high-frequency Doppler lidar measurements is presented. The turbulence estimations are based on wind reconstruction using 3D Doppler lidar observations and a particle filter.
