摘要
随着我国极地科学研究、极地资源勘探与开发、极地航运等活动的持续拓展,对极地通信的需求不断提高。短波通信利用电离层反射可实现数千千米的远距离传输,具有部署灵活、抗毁性强的优点,是极地地区重要的通信手段之一。对极地地区特殊的电离层特性与电离层模型研究现状进行详细分析,针对短波信道模型、频谱感知预测与探测建链、通信波形设计和超远距离链路设计等方面,梳理了极地短波通信的研究现状,分析总结了极地短波通信面临的信道建模、频率确定、波形设计和技术验证难等主要挑战,并从加强电离层斜向探测、数据驱动的频率预测、探测与通信波形设计和人工智能赋能短波通信等多个角度阐述了极地短波通信未来的研究方向。
With the continuous expansion of China's activities in polar scientific research,resource exploration and development,and polar shipping,the demand for polar communications continues to grow.The shortwave communication,capable of achieving long-distance transmission over thousands of kilometers through ionospheric reflection,features flexible deployment and strong survivability,making it one of the crucial communication means in polar regions.This paper first conducts a detailed analysis of the current research status of the unique ionospheric characteristics in polar regions and ionospheric models.It then reviews the research status of polar shortwave communications across four key areas:shortwave channel modeling,spectrum sensing prediction and channel detection and link establishment,communication waveform design,and ultra-long-distance link design.After that,this study summarizes four major challenges in polar shortwave communications:difficulties in channel modeling,frequency determination,waveform design,and technical verification.Finally,it proposes future research directions of polar shortwave communications from multiple perspectives,including enhanced ionospheric oblique sounding,datadriven frequency prediction,channel detection and communication waveform design,and AI-enabled shortwave communication technologies.
