摘要
本文在电磁干扰预测方程的基础上,采用场路协同仿真的分析方法,针对机上敏感设备的发射机、接收机建立了电磁兼容行为级模型和天线模型,分析了设备的受扰程度,并提出了干扰抑制方法。本文的研究可有效解决机载通信系统设备间的电磁干扰问题,提高工作效率,也能为机载通信系统的频谱规划和设备研制工作提供基础理论支撑。
Based on electromagnetic interference （EMI） prediction equation （EMIPE）, EMI behavioral models of transmitter and receiver in some airborne sensitive equipments as well as antenna model are built by way of filed - circuit cooperative simulation ; susceptibility of equipment is analyzed ; and interference suppression method is pres- ented. The research result provides an effective solution for suppressing electromagnetic interferences between air- borne equipments, and working efficiency can be improved, which also gives basic theoretical support for spectrum planning of airborne communication system and equipment development.
