短波移动通信新军突起郑祖辉短波通信是利用电磁波通过电离层的反射和折射来进行信息传输的无线电通信。电离层是一种天然的传输媒介，有人称它为天然的中继器，所以它使短波通信具有设备简单、成本低、通信距离远、机动性强以及容易组网等优点。但是，电离层易受太阳黑子... Shortwave Mobile Communications Emergence of the New Army Zheng Zuhui Shortwave communication is the use of electromagnetic waves through the ionospheric reflection and refraction of information for the transmission of radio communications. Ionosphere is a natural transmission medium, some people call it a natural repeater, so it makes the shortwave communication has the advantages of simple equipment, low cost, communication distance, mobility and easy networking. However, the ionosphere is susceptible to sunspots ...
