Seasonal variation of site diversity performance

A study of the seasonal performance of site diversity (SD) using four years of rain radar measurements in South England is presented. Detailed analyses of site diversity gain as well as the spatial correlation of rain attenuation at pairs of sites of various separation distances and baseline orientations reveal significant seasonal dependence, a much greater efficacy of SD for fade mitigation in the summer and a larger sensitivity of the technique to baseline orientation in non-summer seasons.
