摘　　要：针对工程设计中综合射频系统高空核电磁脉冲(high altitude nuclear electromagnetic pulse,HEMP)防护指标无法分解到各组成设备的难题,研究HEMP对综合射频系统的耦合.采用多通道耦合分析与验证方法,分别对综合射频系统“超短波”(very-high frequency,VHF)天线、“短波”(high frequency,HF)天线、L波段天线、机架以及互联线缆的HEMP耦合进行了仿真分析,并在有界波实验室开展了相应的测试.仿真和试验结果显示:最主要的耦合通道是VHF天线,最大耦合电压达800 V;次要通道是综合射频机架模块的非金属连接器孔缝,最大耦合电压达100 V;HEMP对屏蔽线缆的耦合电压忽略不计.以上耦合电压指标可作为机载综合射频系统分解到各个天线和模块的工程防护设计指标要求.Aiming at the problem that high altitude nuclear electromagnetic pulse(HEMP)protection index of integrated radio frequency system cannot be decomposed into each component equipment in engineering design,the coupling of HEMP to the integrated radio frequency system(IRFS)is studied.A multi-channel coupling analysis and verification method is adopted.The HEMP coupling of VHF antenna,HF antenna,L band antenna,frame and interconnected cable in the IRFS is simulated and analyzed,and corresponding tests in the bounded wave HEMP simulators conducted.Simulation and test results show that the most important channel for HEMP coupling to IRFS is the VHF antenna,and the maximum coupled voltage is up to 800 V.The secondary channel is the aperture of the non-metallic connector of the IRFS rack module,and the maximum coupled voltage of the aperture is up to 100 V.The coupling voltage of the cable can be ignored.These coupling voltage indices can be used as engineering protection design indices for airborne IRFS,and be decomposed into various antennas and modules.
