Abstract
Analysis of signal statistical characteristics is
carried out, and estimation errors of the radial wind velocity are
calculated by use of numerical simulation of a cw Doppler lidar return,
taking into account the atmospheric aerosol microstructure. It has
been found that, at small sounded volume, the large particles
contribute significantly to the scattered field. As a result the
lidar return probability density function distribution can differ
significantly from a Gaussian distribution. Neglect of the aerosol
microstructure effect results in considerable underestimation of the
error of cw Doppler lidar velocity estimates at small sounded
volume.
