摘要:

为避免欺骗式干扰对卫星导航构成重大威胁，研究了卫星导航欺骗式干扰抑制技术。首先，根据欺骗式干扰产生原理和实施方式将其分为四类，之后论述了国内外欺骗式干扰和欺骗式干扰抑制技术的研究现状，调研了国内外主要研究机构针对欺骗式干扰抑制采取的技术措施，进一步按照适用接收机的类型对技术进行了分类，并对各类技术对于四类干扰的抑制效果进行了逐一对比分析。在此基础上，展望了未来欺骗式干扰抑制技术的发展趋势，对从事该项技术的研究者具有一定的参考借鉴价值。

Abstract:

To avoid the major threat spoofing poses to satellite navigation, anti-spoofing technology of satellite navigation is studied. Initially, four categories of spoofing are presented according to its principle and implementation. Then the research status of spoofing and anti-spoofing technology is discussed, technical measures adopted by major research institutes are investigated. Further the technology is classified according to the types of applicable receivers, and the spoofing suppression effects of various technologies are compared and analyzed. On this basis, the development trend of anti-spoofing technology in the future is prospected, which provides a reference to the researcher who is engaged in this technology.
