摘　　要：全球定位系统在现代社会中的作用不容小觑,因此对该系统的欺骗与抗欺骗技术的研究成为一个重要的课题。研究卫星导航系统欺骗与抗欺骗技术,对提高北斗导航系统的安全性与可靠性具有重要的意义。针对卫星导航系统的欺骗技术与抗欺骗技术,首先建立欺骗信号与真实信号的数学模型,然后分析欺骗信号的生成方式及优缺点,从欺骗检测和欺骗抑制两方面分析现有的抗欺骗方法,研究抗欺骗方法的适应性与不足,最后进行总结与展望。Its role in the modern society should not be underestimated, thus the research, on spoofing and anti-spoofing technology of the satellite navigation system has an important significance in improving the security and reliability of the Beidou navigation system. The spoofing and anti-spoofing technology of satellite navigation system is discussed. Firstly, the mathematic models of spoofing signal and real signal are established. Then, the generation methods of spoofing signal and their advantages and disadvantages are analyzed, the anti-spoofing methods expounded from the aspact of spoofing detection and spoofing mitigation, and the adaptability and deficiency of the anti-spoofing method explored. Finally, the summary and prospect of the related technologv is done.
