海面蒸发波导微波超视距通信可行性分析

海面蒸发波导是海洋环境下可有效增强无线信号而实现超视距传播的一种媒质。介绍了海面蒸发波导的基本概念、传播机理以及国外研究概况,分析了利用这种信道资源实现微波超视距通信的可行性,表明其传输信道稳定,具有较高的通信可用度,可以为海域船只之间、船只与陆地或岛屿之间的远距离大容量信息传输提供一种新型的可用通信手段。

Feasibility Analysis on beyond-horizon Microwave Communication with Evaporation Duct over the Sea

Evaporation duct is a medium that can substantially increase radio signals,resulting in BLOS propagation over the sea.The paper gives an introduction to the basic conception,propagation mechanism,foreign research situation overview of evaporation duct,and analyzes the feasibility of accomplishing beyond-horizon microwave communication by using this channel resource,which indicates it is a kind of steady channel with relatively high availability.Therefore,by this new usable communication means,we can achieve a long distance and large capacity transmission between boats as well as between boat and shore or island over the maritime space.
