反无人机系统干扰民航GPS信号的技术分析及思考

Technical Analysis and Consideration of Anti UAV System Interfering GPS Signal of Civil Aviation

目前快速发展兴起的无人机市场缺乏有效监管,无人机干扰民航事件频频发生,反无人机技术应运而生。现阶段,对无人机的管控大部分采用的是大功率信号压制干扰方式。这不仅会使无人机的航迹不可控造成二次伤害,还会对民航造成威胁。文章针对一起由反无人机系统干扰民航通信的排查工作,结合反无人机技术概况与民航应用中GNSS的稳健性和安全性分析民航无线电干扰。

At present,the rapidly developing and emerging uav market lacks effective supervision,and frequent incidents of interference with civil aviation by drones have resulted in the emergence of anti-uav technology.Now,the control of uav mostly adopts the mode of highpower signal suppression and interference.This will not only cause secondary damage due to uncontrollable fl ight path of the uav,but also pose a threat to civil aviation.Aiming at the investigation of civil aviation communication interference by anti-uav system,this article analyzes civil aviation radio interference based on the general situation of uav technology and GNSS robustness and safety in civil aviation application.
