Abstract
The contributions of Fresnel reflection, and anisotropic and isotropic turbulent scatter to radar signals at low very high frequencies received at near vertical incidence from the troposphere and lower stratosphere are analyzed. The analysis is concerned with the derivation of the three lowest moments of the spectrum of the returned echo to provide measures of the total returned power, the velocity in the radar beam direction, and the variance of the velocity within the radar volume, which indicates the intensity of the turbulence. The simultaneous observation of the degree of aspect sensitivity between the vertical and off-vertical beams also indicates the nature of the turbulence. A low degree aspect sensitivity implies an isotropic turbulence.
