摘要

介绍了海洋云层和降水的特点以及云层和降水对电波吸收的影响；描述了海洋层状雨和对流雨的降雨空间结构状态以及对高频段卫星通信雨衰的影响；分析了高频段卫星通信雨衰原因，指出了电磁波吸收、热噪声和去极化是影响高频段雨衰的重要方面，并针对海上工作环境特点提出了上行功率控制、频率分集、速率分集、自适应调制等抗雨衰方法.

Abstract

Firstly we introduced the characteristics of ocean clouds and precipitation as well as their influence on electric 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-polarization 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、velocity diversity and self-adaptive modulation etc.
