配备GPS/INS组合导航系统的无人机诱捕方法

Method of Trapping UAV Equipped with GPS/INS Integrated Navigation System

针对黑飞无人机威胁空域安全问题,结合无人机卫星/惯性组合导航(Global Positioning System/Inertial Navigation System,GPS/INS)系统的归一化新息平方(Normalized Innovation Squared,NIS)检测和GPS欺骗原理,分析了欺骗距离和GPS定位精度对诱捕无人机的影响,设计了一套诱捕无人机的完整步骤,研究目标是在不被无人机发觉的前提下将无人机诱骗至指定位置。通过理论分析和仿真,验证了该方法不仅可以诱捕无人机,还不易被检测到。

Aiming at the problem of‘black flight’UAV threatened airspace security,this paper designed a complete set of steps to trap UAV by combining the NIS detection of the GPS/INS integrated navigation system of UAV with theory of GPS spoofing and analyzing the influence of deceptive distance and GPS positioning accuracy on trapping UAV,the research goal is to lure UAV to a designated location without being detected by UAV.It was verified that this method cannot only trap UAV,but also is hard to detect,through theoretical analysis and simulation experiments.
