Computer simulation of coherent Doppler lidar measurement of wind velocity and retrieval of turbulent wind statistics

Abstract

We describe the algorithms for the simulation of cw and pulsed coherent Doppler wind lidar operation in a turbulent atmosphere and the methods to estimate the mean wind and the parameters of small-scale wind turbulence from lidar data. The algorithms are realized as LabView computer codes, which include parts simulating the atmospheric turbulent wind fields based on the Karman model, lidar signal, and data processing. The errors for lidar measurement of turbulent parameters and the retrieval of the wind vertical profiles are estimated based on a computer simulation of the coherent Doppler lidar system operation.
