Paper Abstract

The effect of dynamic turbulence of the atmosphere on the statistical uncertainty of wind velocity vector components measured by cw coherent lidar using sector conical scanning method has been studied. The calculations of the variance of wind velocity estimates for different scan sector angles and number of scan repetitions (rotations) have been carried out. The results obtained theoretically are compared to experimental data. It is shown that the increase of both the ratio of scan cone foundation radius to outer scale of turbulence and the number of rotations cannot considerably decrease significant random errors arising in lidar wind velocity estimates at small scan sector angles. The spatial averaging of wind velocity fluctuations over lidar sounding volume and corresponding decrease of measurement errors takes place only when scan sector angle exceeds 270 degrees.
