Abstract : The statistics of the turbulent field of reflectivity and velocity obtained by a radar include the effect of averaging over a pulse volume and a time interval. In this work, recovery of the original characteristics of the turbulence from the filtered forms is considered. The functional dependence of the turbulence structure function on the structure function of the pulse volume-averaged velocity field is shown to be too complicated for practical use. However, effective and relatively simple methods for recovery of the original turbulence spectra from the measured longitudinal and lateral pulse volume-filtered spectra rare derived. (Author)
