摘要
随着消费级无人机带来的安全威胁日益凸显,无人机反制技术也越来越被重视。首先,介绍市场上主流消费级无人机内置的"禁飞区"功能限制。其次,介绍生成式卫星导航欺骗干扰信号的生成及欺骗无人机定位在"禁飞区"区域内,从而实现诱捕无人机的原理。然后,详细介绍一种基于FPGA和AD9361的生成式卫星导航欺骗干扰的无人机诱捕方案设计,并完成硬件电路实现。最后,通过外场试验,成功完成对无人机卫星导航接收机的欺骗干扰,实现对无人机的有效诱捕,验证了本方案设计的正确性。
With the security threats brought by consumer unmanned aerial vehicles(UAVs) becoming increasingly prominent, anti-UAV technologies are paid more and more attentions. Firstly, it is introduced that is the built-in ’no-fly zone’ restriction function of the mainstream UAVs in the market. Secondly, the generation of spoofing signals for generative satellite navigation and the principle of positioning victim UAVs in no-fly zone which result in the trapping of UAVs are introduced. Then, a design is narrated of UAV trapping scheme for generative satellite navigation spoofing based on Field Programmable Gate Array(FPGA) and AD9361 in detail, and the hardware circuit design is realized. Finally, the generative spoofing of Global Navigation Satellite System(GNSS) receiver is successfully completed through field tests, which leads to effective UAV trapping;therefore the correctness of the scheme design is validated.
