电子对抗技术的发展使欺骗干扰日益成为无人机通信系统中面临的现实威胁,然而目前尚无公开文献研究无人机上行链路中的抗欺骗干扰技术.针对上述问题,研究了欺骗干扰存在时的上行链路接收信号模型,并从信号处理层面和信息处理层面相结合的角度,结合无人机上行链路的特点,提出了一种可靠的无人机上行链路抗欺骗干扰方案.并通过Matlab和C语言对所提方案进行了建模仿真,仿真结果显示,该方案可有效地对欺骗信号进行检测、分类和消除,并可通过认证技术来保证接收信息的真实性.研究表明,在信号处理阶段对欺骗干扰信号进行处理,在信息处理阶段对真实信息进行认证,可有效避免欺骗干扰的影响.%With the development of electronic countermeasure technology,spoofing jamming is becoming a realistic threaten in UAV(unmanned aerial vehicle) communication system.As of now,there is no open material presenting the detail on the anti-spoofing technology in UAV uplink.In order to solve such problem,the uplink receiving signal model is studied in the presence of spoofing jamming,and then combining the signal processing layer with the information processing layer,a reliable anti-spoofing scheme for UAV uplink is proposed.The model of the proposed anti-spoofing scheme is built by Matlab and C language to simulate the real conditions.The simulation results show that the scheme can not only detect,classify and eliminate the spoofing signals,but also ensure the authenticity of the received information through the authentication technology.The research shows that the proposed scheme can effectively avoid the effect of spoofing jamming by removing the spoofing signals in signal processing layer and authenticating the incoming information in information processing layer.
