论文摘要
GNSS接收者容易受到干扰和欺骗攻击的攻击，在过去的十年中，全世界已经报道了许多此类事件。重要的是要快速检测攻击和本地化攻击者，如果没有专用的传感基础架构，这可能很难即使不是不可能。参与性传感或人群的概念是，大量的自愿贡献者提供了测量，而不是依靠专用的感应基础架构。这项工作考虑了嵌入式GNSS接收器，以提供参与性干扰检测和本地化的测量。具体而言，这项工作提出了一种基于参与式感应的新型堵塞本地化算法，该算法利用了商业GNSS接收器的AGC和C/N_0估计。所提出的算法不需要了解干扰能力或通道的知识，而是自动估计所有参数。该算法显示在相关方案中的表现优于类似的最新本地化算法。
GNSS receivers are vulnerable to jamming and spoofing attacks, and numerous such incidents have been reported worldwide in the last decade. It is important to detect attacks fast and localize attackers, which can be hard if not impossible without dedicated sensing infrastructure. The notion of participatory sensing, or crowdsensing, is that a large ensemble of voluntary contributors provides the measurements, rather than relying on dedicated sensing infrastructure. This work considers embedded GNSS receivers to provide measurements for participatory jamming detection and localization. Specifically, this work proposes a novel jamming localization algorithm, based on participatory sensing, that exploits AGC and C/N_0 estimates from commercial GNSS receivers. The proposed algorithm does not require knowledge of the jamming power nor of the channels, but automatically estimates all parameters. The algorithm is shown to outperform similar state-of-the-art localization algorithms in relevant scenarios.
