摘要
近年来超短波微波超视距通信研究越来越受到关注,因此分析了对流层散射通信机理、蒸发波导机理和超视距传播形成条件,提出了基于对流层散射和蒸发波导混合模式的海上超视距通信应用方法。通过仿真验证该方法具有有效性,并给出了海上舰船超视距通信应用建议,可为舰船超短波微波超视距通信系统设计与应用提供技术支撑。
In recent years,more and more attention has been paid to the research of beyond-line-of-sight communication at ultrashort wave and microwave frequency band.This paper analyzes the mechanism of troposcatter communication,the mechanism of evaporation duct and the formation conditions of beyond-lineof-sight propagation,puts forward the application method of offshore beyond-line-of-sight communication based on the mixing mode of troposcatter and evaporation duct.And simulation indicates the effectiveness of this method.Finally,some suggestions on the application of beyond-line-of-sight communication for naval ships at sea are given.The research results can provide technical support for the design and application of ship’s beyond-line-of-sight communication systems at ultrashort wave and microwave frequency band.
