Scientific paper

A digital technique for the extraction of Doppler shift data from SODAR echoes in planetary boundary layer studies is described. After the harmonic analysis of the digitized signal, the characteristics of the echo are determined in a limited spectral zone. It is shown that the errors due to noise are considerably reduced by limiting the analysis to the spectral region in which the echo is found.
