Electromagnetic wave depolarization is a key effect to be taken into account in dual polarization systems. Clouds and hydrometeors in the troposphere affect Earth-satellite links working in the Extremely High Frequency (EHF) band, causing the additional detrimental effect of depolarization. This contribution presents the current activities carried out at Politecnico di Milano on the investigation of the Cross-Polar Discrimination (XPD) measured in past electromagnetic wave propagation campaigns (Italsat, Alphasat). A physical based model is under development to support the analysis of the XPD.

Abstract
Electromagnetic wave depolarization is a key effect to be taken into account in dual polarization systems. Clouds and hydrometeors in the troposphere affect Earth-satellite links working in the Extremely High Frequency (EHF) band, causing the additional detrimental effect of depolarization. This contribution presents the current activities carried out at Politecnico di Milano on the investigation of the Cross-Polar Discrimination (XPD) measured in past electromagnetic wave propagation campaigns (Italsat, Alphasat). A physical based model is under development to support the analysis of the XPD.File in questo prodotto:
