GNSS干扰和欺骗检测研究现状与展望

Research Status and Prospect of GNSS Jamming and Spoofing Detection

  • 摘要: 全球卫星导航系统(GNSS)提供精确的定位、导航和授时功能,在军事和国民经济各行各业发挥着关键作用,其安全问题成为目前人们关注的焦点。GNSS信号强度较弱且民用GNSS具有开放结构,因此容易受到干扰或欺骗。GNSS干扰和欺骗轻则影响GNSS定位精度或提供错误的路线,降低服务质量;重则导致GNSS中断,提供虚假时间和位置信息,造成经济损失和军事行动失败等严重后果。虽然GNSS系统安全问题研究成果丰富,但相关研究论文分散在不同领域的刊物上,缺乏从无线电监管的角度论述GNSS干扰和欺骗检测、实验系统和数据集方面的综述性论文。基于此,该文从原理、检测方法、实验系统和开源数据集方面调研了大量代表性文献,按照“原理-检测-实验系统-数据集”较为系统地阐述了GNSS干扰和欺骗检测的研究现状。首先,介绍了GNSS干扰的原理和分类,讨论了基于统计的干扰检测方法、基于时频分析的干扰检测方法和基于机器学习的干扰检测方法;其次,介绍了欺骗的原理和分类,并从是否需要附加硬件和卫星信号从生成到最终实现定位过程两个方面介绍了欺骗检测方法;然后,介绍了国内外研究GNSS干扰和欺骗的实验系统和开源数据集;最后,对研究现状和未来的发展趋势进行总结和展望,旨在促进GNSS干扰和欺骗检测理论和技术的发展及其在无线电监测领域的推广应用。

     

    Abstract: ‍ ‍The Global Navigation Satellite System (GNSS) plays a critical role in the military defense and in diverse range of the national economy. Today, the security of GNSS has become a significant concern. GNSS is fragile and vulnerable to jamming or spoofing because of the weak signal strength and the open architecture of civilian GNSS. GNSS jamming and spoofing can affect GNSS positioning accuracy or provide incorrect routes, reducing the quality of service in minor cases, can lead to serious consequences such as interruptions, economic losses and failure of military operations in severe cases. Although there is a wealth of research results on GNSS system security issues, the related research papers are scattered in publications in different fields, and review papers dealing with GNSS jamming and spoofing detection, experimental systems and datasets from a radio monitoring and regulatory perspective are lacking. Based on the situation, the paper surveys a large amount of representative literature in terms of principles, detection methods, experimental systems and open source datasets, and presents the current state of research on GNSS interference and spoofing detection in a more systematic manner according to “principles-detection-experimental systems-datasets”. The principles and classification of GNSS jamming are firstly introduced, and the statistical-based detection, time-frequency analysis-based detection and machine-learning-based detection methods are discussed, respectively. Secondly, the principle of GNSS spoofing is introduced, and spoofing detection techniques are presented in terms of whether additional hardware is required, and the process of satellite signals from generation to the final realization of positioning. Then, experimental systems and open-source datasets for jamming and spoofing are presented. Finally, the current status and future trends are summarized and prospected, aiming to promote the development of GNSS jamming and spoofing detection theories and techniques and to facilitate their applications in radio monitoring field.
