摘　　要：随着无人机技术在低空经济领域的日益普及与应用,非法(黑飞)无人机对铁路运营带来潜在威胁的风险增大。为此,提出一种基于信号接收与定向发射技术的无人机反制方案。通过模块化部署信号接收与定向发射设备,能够在复杂的铁路沿线环境中提供连续的干扰信号覆盖,有效防止非法飞行无人机接近铁路区域。同时,为避免正常巡检无人机受到干扰,使用定制款的巡检无人机抗干扰模块,以保障其在复杂电磁环境中的稳定运行。仿真与实验结果表明,该方案不仅具备较高的技术可行性,还能实现低成本、持续稳定的铁路沿线无人机反制,提升铁路安全防护的能力。With the increasing popularity and application of drone technology in the low-altitude economy,potential threats posed by illegal(rogue)drones to railway operations have become more prominent.To address this issue,this paper proposes a drone countermeasure solution based on signal reception and directional transmission technology.Through modular deployment of signal reception and directional transmission devices,continuous interference signal coverage can be provided in the complex railway environment,effectively preventing illegal drones from approaching railway areas.Meanwhile,to avoid interference with normal inspection drones,a customized anti-jamming module for inspection drones is used to ensure their stable operation in complex electromagnetic environments.Simulation and experimental results indicate that the proposed solution not only has high technical feasibility but also enables low-cost and sustainable drone countermeasures along railway lines,enhancing the railway's safety protection capabilities.
