无人机位置欺骗验证与检测方法研究
|
摘要
如今无人机(Unmanned Aerial Vehicle,UAV)应用领域越来越广,其定位导航主要依赖卫星导航系统,而卫星导航民用信号格式又完全公开,所以存在被欺骗的潜在威胁。针对此问题,在Android开发环境下,利用大疆公司DJI Mobile SDK的软件开发工具,研究了Remote Controller库函数的使用方法,基于该库函数开发了无人机位置实时显示APP软件,可安装在任何安卓终端上用于无线获取无人机的位置信息。利用卫星导航信号模拟器设置欺骗位置,通过天线发出,在实际信号环境下成功实现了对无人机的位置欺骗。在此基础上,提出了基于位置跳变和伪距变化检测的无人机欺骗干扰检测方法,并进行了实际信号测试验证。本文揭示了无人机易受欺骗的潜在威胁,并提出了欺骗检测应对措施,对无人机应用领域的导航安全防护有重要参考价值。
Nowadays,the application field of UAV is becoming more and more wide,and it's positioning and navigation mainly depends on the satellite navigation system,and the satellite navigation signal format is completely open,so there is a potential threat to be deceived. In order to solve this problem,in the environment of Android development,using the software development tool of DJI Mobile SDK of Dajiang company,the method of using RemoteController library function is studied. Based on the library function,the real-time display APP software of unmanned aerial vehicle location is developed,which can be installed on any Android terminal for wireless acquisition of UAV location information. The deception position is set up by the satellite navigation signal simulator,and the position deception of UAV is successfully achieved under the actual signal environment. On this basis,a detection method of deception jamming for UAV Based on location hopping and pseudo range change detection is proposed,and verified by actual signal. This paper reveals the potential threat to deception of unmanned aerial vehicle(UAV),and puts forward the Countermeasures of deception detection,which has important reference value for the navigation security protection of UAV in the application field.
