Simulation of the coherent Doppler LiDAR signal requires accurate computation of homogeneous random wind fields. Based on complex random processes with specified spatial statistics given by the covariance function, an improved real correlation random wind field algorithm is proposed for real random processes, the simulation results are compared with the given covariance function and the real correlation algorithm conforms to the given covariance function quite well.Moreover, to validate the accuracy of the real correlation algorithm, the estimation of the turbulence energy dissipation rate (TEDR) from the Doppler spectrum width is described. Using the generated real random wind field, the estimation relative bias of the TEDR is retrieved. The accuracy of the simulation is in accordance with the experimental results.
