Tropospheric influence on the radio wave propagation of a satellite system can be primarily divided into clear-air effects and hydrometeor effects, which affect the key propagation factors determinative of the satellite’s system performance at 30 GHz frequency band and above [1–3]. Clear-air effects mainly include refraction/scintillation and defocusing effects of altitude-varying atmosphere, the effect of runoff generation structure in the atmosphere on the radio waves, and absorption attenuation of the radio waves due to the oxygen and water vapor molecules present in the atmosphere [4, 5].

摘要

Tropospheric influence on the radio wave propagation of a satellite system can be primarily divided into clear-air effects and hydrometeor effects, which affect the key propagation factors determinative of the satellite’s system performance at 30 GHz frequency band and above [1–3]. Clear-air effects mainly include refraction/scintillation and defocusing effects of altitude-varying atmosphere, the effect of runoff generation structure in the atmosphere on the radio waves, and absorption attenuation of the radio waves due to the oxygen and water vapor molecules present in the atmosphere [4, 5].
