Paper Abstract

In this paper the theoretical approach to the investigation of the measurement accuracy of the true radial velocity in the turbulent atmosphere is proposed. This approach takes into account the non-Gaussian statistics effect of the Doppler lidar signal and the spatial averaging effect. The cases of the maximum likelihood method, the autocorrelation function method, and the spectral function method are considered. It is shown that the measurement accuracy of the true radial velocity measurement depends on the signal statistics, i.e., the parameters of the atmospheric turbulence and a Doppler lidar used. The measurement error variance of the true radial velocity is the sum of the Gaussian and the non-Gaussian components. It follows from the comparative analysis of the measurement accuracy of the true and average radial velocities that measurement error variances have different values. The Gaussian components of the measurement error variances of the true and average radial velocities have the same from. The non-Gaussian components of the measurement error variances have the different values. The non-Gaussian component is not averaged with increasing the scattering volume length; it tends to a constant value.
