摘要
民用无人机大量普及,飞行故障不断出现。为提高强电磁环境下无人机的电磁防护能力,快速准确定位敏感部件及干扰传播路径,提出一种无人机近场注入噪声技术方案,通过向无人机注入交变电场和磁场干扰,以重现无人机在强电磁环境下的跌落现象。文章介绍了敏感部件及敏感性质、干扰入侵路径、受扰阈值的确认方法,对无人机进行电磁防护加固措施的验证具有一定的参考意义。
The widespread use of civilian unmanned aerial vehicle(UAV)has led to frequent flight malfunctions.In order to improve the electromagnetic protection capability of UAV in strong electromagnetic environment,quickly and accurately locate sensitive components and interference propagation path,a near-field noise injection technology scheme for UAV is proposed.By injecting alternating electric and magnetic field interference into UAV,the drop phenomenon of UAV in strong electromagnetic environment is reproduced.The article introduces the confirmation methods of sensitive components and sensitive properties,interference invasion path and disturbance threshold,which has certain reference significance for the verification of electromagnetic protection and reinforcement measures of UAV.
