Impacts of High-power Electromagnetic Pulses on Wireless Communication Systems and Networks

面对高频段人造强电磁脉冲的威胁,无线通信射频器件和模块表现出易受损、易干扰的缺陷,为提升无线通信系统和网络的电磁兼容性并有针对性地对其进行电磁防护,需系统地掌握强电磁脉冲对无线通信系统和网络的作用效应。目前,此效应的研究主要集中在器件和模块层面,在系统级和网络级方面仍存在很多空白领域,需要开展探索性研究以阐明内在的影响规律和物理机制。文章从无线通信系统的角度,介绍了国内外无线通信射频器件、模块、系统以及无线通信网络的电磁脉冲效应研究的相关成果,并对潜在的研究方向进行了思考和展望。

The radio-frequency components and modules of these wireless systems and devices are sensitive and vulnerable when facing the attacks of high-frequency intentional high-power electromagnetic pulses.In order to improve the electromagnetic compatibility and strengthen the protection of the wireless communication systems,it is necessary to obtain in-depth understanding of the impacts of the high-power electromagnetic pulses on wireless communication systems and networks.Thus far,the research campaigns have been focused on the high-power electromagnetic pulse effects of the radio-frequency components and modules,whereas the investigation studies on the system and network levels are rare–more works need to be carried out to explore the underlying rules and mechanisms.Here,an overview of the effects of electromagnetic pulses on the wireless communication components,modules,systems,and networks is provided.Moreover,the potential directions for future research in this area are also suggested and discussed.
