Paper Abstract

The problem concerned with the photocurrent frequency fluctuations of the cw-Doppler lidar and the pulsed Doppler lidar caused by the wind velocity fluctuations is considered. This problem is formulated based on the theoretical results of the study of the optical radiation scattered by suspended particles in a turbulent flow. It is shown that the measurement error of the average Doppler wind velocity depends on the photocurrent statistical characteristics. In the case of the non-Gaussian statistical characteristics the accuracy of the average wind velocity measurements increases with the increase of the scattering volume length. In the case of the Gaussian statistical characteristics the error of the average wind velocity measurements increases and saturates at the constant level with the increase of the scattering volume length. The theoretical results obtained are in agreement with the experimental data.
