Overview of Satellite Navigation Spoofing Signal Detection Technology

摘要: 卫星导航欺骗干扰信号检测是卫星导航接收机实施欺骗干扰抑制、防止产生错误定位和测速、定时信息的必要步骤.在介绍了导航战背景下卫星导航欺骗干扰技术的基础上,分析比较了当前主要卫星导航欺骗干扰信号检测技术的实现难度、效果和场景适应性,指出了现阶段卫星导航接收机端最具研究价值的欺骗干扰信号检测技术.最后对欺骗干扰检测技术研究的趋势和发展方向进行了总结展望.

Abstract: The detection of satellite navigation spoofing signal provides a precondition for spoofing interference suppression of satellite navigation receivers,which prevents the receivers displaying error positioning, speed measurement and timing information.After introducing the development of satellite navigation spoofing technology in the background of navigation war, this paper analyzes the difficulty,effect and adaptability of the main satellite navigation spoofing detection technologies, points out the most valuable spoofing signal detection technologies in satellite navigation receiver. At last,the trend and development direction of the spoofing detection research are summarized and prospected.
