Attenuation and phase shift of microwaves due to canted raindrops

This paper discusses the results of a quantitative estimation of changes in propagation parameters, i.e., attenuation and phase shift, due to the canting of raindrops for both horizontal and vertical polarizations. These results show that the difference in propagation behavior between satellite-earth paths (i.e., slant paths) and terrestrial paths is significant if raindrops are canted. In many cases, the canting effect produces large amplitude and phase variations which are important even for propagation studies concerning a single polarized transmitter-receiver channel.
