摘要
现阶段,中国民用地空通甚高频无线电系统采取天线共用的形式,它的主要功能是分开地面接收与发射的信息,从而避免地面接收信息的混杂,也有效地弥补了单一天线所造成的场地紧张和交叉干扰的缺陷,从而大幅提高了地面与空间通信的准确性。但由于其构造简易、使用程度低,因此导致它在实际使用中的应用受到限制。文章对天线公用设备的构造、使用与调试中的问题展开了讨论,并提出了具体的使用建议。
At this stage,China's civil ground-to-air VHF radio system takes the form of shared antennas.Its main function is to separate the information received and transmitted on the ground,so as to avoid the confusion of the information received on the ground,and effectively overcome the problems caused by a simple antenna.The defects of site tension and cross-interference greatly improve the accuracy of ground and space communication.However,due to its simple structure and low degree of use,its application in practical use is limited.The article discusses the construction,use and debugging of antenna public equipment,and puts forward specific usage suggestions.
