摘要
Abstract
Firstly we introduced the characteristics of ocean clouds and precipitation as well as their influence on elec-tric wave absorption,and described the rainfall space structure appearance of ocean layer rain and convection rain and their influence on high frequency band satellite communication rain decline.Then we analyzed the reasons of high frequency band satellite communication rain attenuation,and pointed out that the electromagnetic wave absorption,hot noise and de-polariza-tion are important aspects that lead to high frequency rain attenuation.Finally,considering the ocean working environment characteristics,we put forward some methods to resist rain attenuation such as uplink power control,frequency diversity、ve-locity diversity and self-adaptive modulation etc.关键词
