Abstract - Radar data collected at an experimental facility arranged on purpose suggest that thefootprint of atmospheric turbulence might be encoded in the radar signal statistics. Radar dataprobability distributions are calculated and nicely fitted by a one-parameter family of generalizedGumbel (GG) distributions, Ga. A relation between the wind strength and the measured shapeparameter a is obtained. Strong wind fluctuations return pronounced asymmetric leptokurticprofiles, while Gaussian profiles are eventually recovered as the wind fluctuations decrease. Besidesstressing the crucial impact of air turbulence for radar applications, we also confirm the adequacyof Ga statistics for highly correlated complex systems.
