摘　　要：随着电磁环境的日益复杂特别是军事对抗强度的日益加大,卫星导航应用的潜在安全隐患已成为现实威胁.传统的卫星导航抗干扰技术大多针对压制干扰,对欺骗干扰考虑不多,而欺骗干扰对用户造成的危害并不亚于压制干扰.本文简要介绍了欺骗干扰防护技术的研究背景,包括概念、原理、应用案例等,深入分析和总结了国内外抗欺骗干扰技术主要研究进展,最后重点阐述了当前抗欺骗干扰方法存在的问题和未来欺骗防护技术的发展趋势.With the increasing complexity of the electromagnetic environment and the increasing intensity of military confrontations, the potential security exposure in applications of satellite navigation has become a serious concern. Traditional GNSS anti-interference technology generally focuses on eliminating the jamming interference,while providing comparatively less attention to the elimination of spoofing interference. However, the potential risk induced by spoofing interference is no less than that caused by jamming interference. This paper first gives a broad overview of the research background on anti-spoofing technology, including the concept, theory, application cases, etc. Then it concludes and summarizes the research status of GNSS anti-spoofing technology in depth.Finally, it expounds emphatically some viewpoints on the prospect of GNSS anti-spoofing technology.
