【摘要】 无人机在遭受雷击时机载的无线通信模块将面临严重的损伤威胁，亟须对机载无线通信模块的雷电电磁耦合进行深入研究。文中进行了机载无线通信模块的雷电电磁耦合分析及仿真，仿真结果表明，“前门”耦合主要的耦合途径为天线，由电磁环境频率以及天线工作频率决定。“后门”耦合方式主要的耦合途径为机壳以及线缆，机壳屏蔽层极大衰减了雷电电磁能量，但线缆上会产生较大的感应电流和电压。电磁能量进入无线通信模块主要通道为线缆。本研究为机载无线通信模块的电磁损伤特性试验及研究提供了理论支持和仿真依据。更多还原

【Abstract】 When unmanned aerial vehicle(UAV) is struck by lightning, its onboard wireless communication module will face serious threat of damage. There is an urgent need to conduct in-depth research on the lightning electromagnetic coupling of the onboard wireless communication module. The author analyzes and simulates the lightning electromagnetic coupling of the onboard wireless communication module. The simulation results show that the main coupling path of “front-door” coupling is the antenna, which is determined by the frequency of the electromagnetic environment and the operating frequency of the antenna. The main coupling paths of “back-door” coupling are the aircraft shell and cables. The shielding layer of the aircraft shell greatly attenuates the lightning electromagnetic energy, but a large induced current and voltage will be generated on the cables. The main channel for electromagnetic energy to enter the wireless communication module is the cable. This research provides a theoretical support and simulation basis for the experimental study on the electromagnetic damage characteristics of the onboard wireless communication module.更多还原
