无线电技术的迅猛发展,给社会带来了巨大经济效益,为人们提供了极大的方便,但随之而来的负面效应——电磁干扰——也越来越大。电磁干扰是指中断、阻碍、恶化或者限制电子设备的有效性能正常使用的电磁能量,是一种电磁现象。过度的电磁干扰会导致电磁环境日益恶化,它对航空事业的影响已不容忽视。对于民航工作,甚高频、雷达等设备受到干扰,就有可能导致地空通话中断或产生歧义以致无法利用雷达显示屏实时监控飞机的飞行状态。这些成为安全生产中的致命隐患已是众所周知。然而导航设备因受干扰而无法正常运行却比较少见。西安咸阳机场DME设
The rapid development of radio technology has brought tremendous economic benefits to the community and provided great convenience to people. However, the ensuing negative effects - electromagnetic interference - are also getting bigger and bigger. Electromagnetic interference is an electromagnetic phenomenon that interrupts, blocks, worsens, or restricts the normal use of electromagnetic energy the effective performance of electronic equipment. Excessive electromagnetic interference will lead to deteriorating electromagnetic environment, its impact on the aviation industry can not be ignored. Interference with civil aviation, VHF, radar and other equipment may result in the interruption of land-to-air calls or the ambiguity that makes it impossible to monitor the flight status of the aircraft in real time using radar displays. It is well-known that these have become fatal dangers in safe production. However, it is rare for navigation equipment to malfunction due to interference. Xi’an Xianyang Airport DME set
