The In-depth Investigation of Matched-Spectrum Jamming Signals

The safety of GNSS application has always been a concern, especially with the rapid advancement of intelligent autonomous systems in recent decades. Jamming signals pose a significant threat to the vulnerable GNSS receivers. Generally, there are two categories of jamming signals termed as wideband and narrowband, and a multi-step approach is typically leveraged to help detect and mitigate the jamming signal for the safety purpose. In this paper, matched-spectrum jamming signals are investigated and a potential advanced TDM-based Matched Spectrum jamming signal is proposed and validated through the practical experiments. This research provides deep insights into the matched spectrum jamming signals and may aid in developing more advanced countermeasures against this type of dangerous interference.
