摘要
分析了实际电磁环境对无人机的影响,通过在实际飞行环境中对各地面发射机的辐射和场地电磁环境的测试,得到对无人机造成伤害的电磁环境场强极限值在0.1～8×10^3MHz频段中为60～200 V/m.将不同频段下传导干扰与辐射干扰进行结合分析,并根据无人机中存在的辐射干扰和传导干扰的共性特征,得到无人机系统级电磁辐射极限场强在0.1～2×10^3MHz频段中为10～60 V/m.依照国军标GJB3567-99《军用飞机雷电防护鉴定试验方法》,以及在实际飞行场地中采用410 A敏感度测试系统进行测试,结果显示：采用该指标的无人机各机载设备工作正常,未出现设备失灵或降级情况,说明该指标的制定为无人机系统的电磁兼容设计提供了一个有效的评估准则.
The real electro magnetic （EM） environment effects on unmanned aerial vehicle （UAV） is analyzed. And the max harmful outside word EM environment level to UAV is gained after many electromagnetic compatibility（EMC） tests in darkroom and in actual flying field, which is 60-200 V/m in 0.1-8×10^3 MHz bandwidth. The EMC standard at the system level of UAV is advanced as 10-60V/m in 0.1-2×10^3 MHz bandwidth after analyzing the combined effects of conducted and radiated interferences based on the common EM radiated and conducted characteristics of UAV. The UAV was tested in real flying ground by 410A susceptivity testing system and by simulated electromagnetic pulse（EMP） test according to military testing method GJB3567-99. The results reveal that all air-borne equipments based on this standard can work normally and do not degrade, which indicates the standard can provide an effective evacuating rule for EMC of UAV.
