摘要
针对卫星导航系统反电子欺骗需求日益增长这一现状,对卫星导航接收端反电子欺骗的几种关键技术进行了详细介绍,包括基于循环相关捕获的欺骗检测技术、双天线载波相位差检测技术和残留信号检测技术。在此基础上对几种欺骗信号检测方法进行了仿真对比,仿真结果表明,通过上述方法均可有效检测提取欺骗信号,进而达到消除欺骗信号的目的。
In view of growing requirement of satellite navigation system for anti-spoofing,this paper introduces in detail the key technologies of anti-spoofing for satellite navigation receiver,such as deception detection based on cyclic correlation acquisition,dualantenna carrier phase difference detection and residual signal detection. These spoofing detection signal detection methods are simulated and compared. The simulation results show that these methods can effectively detect and extract deceptive signals,and eliminate them.
