Abstract
The method of maximum of function of accumulated spectra (MFAS) has been used for the first time to estimate the wind velocity from measurements with a micropulsed coherent Doppler lidar (MPCDL) during conical scanning with a probing beam. It is ascertained in an experiment with a Windcube 200s MPCDL that MFAS allows an increase in the maximum altitude of retrieval of the vertical profiles of the wind speed and direction by 30% on the average in comparison with the filtered sine-wave fitting.
