在当今多种无线电通信中,短波通信具有最久远的历史,作为战略通信网的关键部分,一直是人防通信的重要手段之一。短波通信与卫星通信等其他传统通信方式相比优势在于,短波通信在传输过程中可以不受地形等限制,相对简单,并且使用成本低廉,有效降低战争过程中通信连接中断等认为破坏的现象。是战时作战指挥通信的秘密武器。虽然过去的短波通信出现可靠性差、通信速低等问题,但随着科技的发展,这些问题已经逐步得到了解决,短波通信也重新引起了人们的重视,重新回到人们的视线范围内,近年来跟更是获得飞快发展。在某些领域甚至可以取代其他传统通信,使人防通信逐步迈向科学化、现代化,在未来国防安全与防空袭斗争中都将发挥至关重要的作用。 Among various radio communications today, HF communications have the longest history. As a key part of the strategic communications network, it has always been one of the important means of civil air defense communications. Compared with other traditional communication methods, such as shortwave communication and satellite communication, the advantages of shortwave communication are that the shortwave communication is not limited by the terrain and so on in the transmission process, and is relatively simple, and the use cost is low, effectively reducing the disruption caused by the interruption of the communication connection during the war. It is a secret weapon for combat command communications in wartime. Although short-wave communications in the past have been characterized by poor reliability and low-speed communications, these problems have been gradually solved with the development of science and technology. Short-wave communications have also re-attracted people’s attention and returned to people’s eyes. In recent years, To follow is to get rapid development. In some areas, it may even replace other traditional communications and make the civil air defense communications be gradually scientifically and modernized. It will play a crucial role in future national defense, security and air strikes.
