Effect of ice-induced cross-polarization on digital earth-space links
Abstract
A statistical analysis of depolarization events observed at 20 HGz from the linearly polarized beacon of ATS-6 is carried out. It is shown that ice depolarization events occur as frequently and are as significant as rain depolarization events, and also that ice crystals are typically canted at 10 deg to the vertical. From the results obtained, the effect of ice cross-polarization on a dual-polarized microwave link with M-ary PSK is investigated and the necessity of implementing cross-polarization cancellation devices is emphasized.
