| 摘 要： | 民机无线电通信、导航、监视(Communication,Navigation,Surveillance,CNS)系统集中了几乎所有的无线电收发设备,设备种类多,工作频段宽且不同设备的工作频率范围重叠,由于天线多,受机体空间约束、空间辐射等因素影响使得电磁兼容(Electromagnetic Compatibility,EMC)问题突出。为此,首先分析了CNS系统的无线电收发设备和天线配置,然后开展电磁兼容性分析找到CNS系统潜在的电磁兼容问题,最后提出从全机天线布局设计、前端电磁兼容加固、频率管理等方面系统解决电磁兼容问题的设计方法。

| Abstract: | Civil aircraft communication,navigation,surveillance(CNS)system includes almost all the receiving and transmitting radios with lots of units and wide work frequency bands.As there are many antennas and the aircraft room is very limited,the electromagnetic compatibility(EMC)issue is serious.For this problem,this paper analyzes the CNS radios and antennas,then estimates the EMC problems of CNS system and finally proposes an EMC solution based on the system level from antenna placement,EMC reinforcement and frequency management. |
