摘　　要：针对强电磁防护需求,研究了加载能量选择表面(ESS)的导航天线强电磁辐照响应。采用三维电磁仿真方式,分别分析了高空核爆(HEMP)、超宽带(UWB)以及高功率微波(HPM)辐照条件下,加载ESS前后导航天线端口输出波形。仿真结果表明,HEMP能量主要分布在几百兆以内,UWB能量分布在较宽范围内,在HEMP和UWB辐照下,加载ESS与否,天线端口输出波形均较低,难以损伤后端电路。HPM能量集中,瞄准导航天线频段时,加载ESS能够有效避免后端电路被损毁。Aiming at strong electromagnetic protection requirements,strong electromagnetic radiation response of navigation antenna with energy selective surface(ESS)loaded is studied.The output waveform of navigation antenna port with(or without)ESS loaded is analyzed by using three dimensional electromagnetic simulation under the radiation of high-altitude electromagnetic pulse(HEMP),ultra-wide band(UWB)and high powered microwaves(HPM).The simulation results show that the energy of HEMP is mainly distributed within several hundred MHz and the energy of UWB within wide frequency range.Under the radiation of HEMP and UWB,whether ESS is loaded or not,the output waveform of antenna port is low,which is difficult to damage the back-end circuit.The energy of HPM is concentrated.When aiming at navigation antenna frequency band,the antenna with ESS loaded can effectively prevent the back-end circuit from being damaged.
