随着民航事业的发展和飞行量的快速增长,甚高频地空通信系统作为保证飞行安全和实施飞行指挥的最基本手段,其重要性越来越为人们所认识和重视。一旦甚高频设备受到强烈的干扰,将会带来不可预见的灾难,小则停飞,重则引发事故,甚至造成空难。我们需要从了解无线电干扰形成的机理出发,要在设备投产前对预设频率进行计算,
With the development of civil aviation and the rapid growth of flight volume, the importance of the VHF air-ground communications system as the most basic means of ensuring flight safety and conducting flight command is becoming more and more recognized and valued. Once VHF equipment is strongly interfered, unforeseen disasters will be caused, while small ones will grounded. Heavy accidents will be caused and air crashes may even result. We need to understand the mechanism of the formation of radio interference, we must start before the equipment on the default frequency calculation,
