摘　　要：热带无线电波传播研究是近年来电波领域重要的研究分支之一。综述了国际电信联盟(ITU)和国际无线电科学联盟(USRI)关于热带无线电波传播的主要研究内容和进展情况,分析了与热带无线电波传播相关的核心影响因素,包括雨衰、对流层闪烁、大气波导、植被衰落、盐度等,最后,指出了关于热带无线电波传播需要进一步研究的方向。相关内容可为热带无线电波传播的深入研究提供参考。Tropical radio wave propagation research is one of the important research branches of wave field in recent years. The main research contents and progresses of tropical radio wave propagation in Interna- tional Telecommunication Union （ITU） and International Union of Radio Sciences （USRI） are summarized, and core factors associated with tropical radio wave propagation are analyzed, including rain attenuation, tropospheric scintillation, surface ducting, vegetation attenuation and salinity. Finally, several future re- search directions for tropical radio wave propagation are prospected. The research in this paper provides some reference for the profound research on tropical radio wave propagation.
