Abstract
The influence is investigated quantitatively of the velocity fluctuations in turbulent atmosphere on the formation of the autocovariance of coherent heterodyne aerosol lidar signals. A multishot, high pulse repetition rate lidar operation is supposed. The limit cases of long-term and short-term averaging are especially considered, when the observation (data accumulation) time is respectively much larger or much less than the correlation time of the fluctuation process. As a result, the intuitive conception is proved and illustrated quatitatively that a long-term averaging, under stationary conditions, allows one to obtain (on the basis of the autocovariance) a range-resolved estimate of the parent population mean Doppler-velocity profile; a short-term averaging allows one to determine a (near) instantaneous range-resolved Doppler-velocity profile.
