针对短波通信系统的应用特点，提出了短波通信发展的关键性问题，描述了短波通信技术的当前发展趋势。对国内外短波通信系统的主要标准和技术体制进行了综述。基于短波通信技术的特点，重点从短波网络体系结构、中继路由、链路层协议、波形传输体制及抗干扰机制的技术特点进行分析，描述了当前短波通信系统的主要技术状态。同时，针对短波通信发展的关键性问题，探讨了后续短波通信技术的发展趋势，对我国建立新一代短波通信系统具有较好的借鉴意义。%Based on the research on the characters of application of high frequency ( HF ) communication system, this paper provides some pivotal problems which accelerate the development of HF communication system. A few of standards and technologies which are compiled in foreign HF communication systems are summarized in this paper. Aiming at the characters of HF communication application, this paper analyses architectures of protocol system, relay route, protocol in link, waveform technology, and link adaptive scheme and so on. At the same time, it discusses the direction of development about HF communication technologies on the basis of pivotal problems in HF communication systems, thus to lead the direction of HF communication systems in our country.
