Scattering of electromagnetic radiation by precipitation particles and propagation characteristics of terrestrial and space communication systems

摘要: The results of applying the Fredholm integral equation method solution to scattering electromagnetic radiation from oblate spheroidal raindrops for communication bands 4, 6, 11, 14, 20, 30 GHz are presented in paper. These amplitudes then used calculate propagation characteristics such as attenuation, phase rotation and crosspolarisation a rain-filled medium. validity using Van de Hulst single-scattering is considered, conditions its use presented. A new more general relationship between horizontal oblique which uses only zenith derive all others. Using Brussard's meteorological model medium containing canted Attenuation equations derived both linear circular polarisation this model, assumes stochastic canting-angle variations. Finally, specific cases terrestrial radio-relay links satellite detailed each. comparison theoretical with experimental depolarisation at 11 also given.
