Retrieval of the turbulence parameters from spatial statistics of Doppler lidar wind estimates

摘要

We describe a technique for estimating the parameters of small-scale wind turbulence from the wind velocity measured with a pulsed solid -state- and CO_2-laser-based coherent Doppler lidar. We present the algorithm for simulation of return signals of pulsed 2 μm and 10.6 μm CDLs along with the methods for estimation of the wind turbulence parameters from the spatial structure function of wind velocity measured by CDL in the cases of both short separations between measurement points (2 μm CDL) and long ones (10.6 μm CDL). The errors in estimation of the turbulent parameters from the lidar data are determined as functions on the signal storage time.
