Twodimensional probability distribution of attenuation and depolarisation on earthspace path
Abstract
Twodimensional probability distribution of attenuation and crosspolarization discrimination (XPD) on earthspace path at 19.5 GHz (circular polarization) is derived. Moreover, the distribution is approximated by a mathematical function. The distribution is compared with the theoretical relationship between raininduced attenuation and XPD, which is based on the deformed raindrop model. It is found that the measured attenuation and XPD values are distributed twodimensionally in an attenuationXPD plane, and the results cannot be explained by the theoretical relationship. This fact implies that special attention should be paid when the XPD statistics on the earthspace path are predicted by the theoretical relationship between attenuation and XPD.
