摘要：

In terrestrial and satellite line-of-sight links, radio waves propagating at Super High Frequency and Extremely High Frequency bands through rain undergo attenuation (absorption and scattering). In this paper, the specific attenuation due to rain is computed using different total cross section models, while the raindrop size distribution is characterised for different rain regimes in the frequency range between 1 and 100 GHz. The Method of Moments is used to model raindrop size distributions, while different extinction coefficients are used to compute the specific rain attenuation. Comparison of theoretical results of the existing models and the proposed models against experimental outcomes for horizontal and vertical polarizations at different rain rates are presented.
