Wind Intensity Inferred from the Alphasat Ka- and Q-band beacon measurements

This contribution focuses on the characterization of scintillation measured exploiting the propagation data collected in the framework of the Alphasat Aldo Paraboni propagation experiment at Politecnico di Milano with NASA equipment. Scintillations spectra are calculated and analyzed, on one side, to assess the quality of the propagation data collected by the experimental receivers on the basis of solid theoretical concepts and, on the other side, to infer information on the wind intensity from the scintillation "corner frequency". Results obtained from beacon data at the two frequencies are in good agreement. In addition, some comparisons have been carried out with the wind speed measured by anemometer installed by NASA at Politecnico di Milano.
