基于解扩互相关的导航欺骗源侦测方法OA

To address the problem of low-power navigation spoofing interference signals that cannot be detected by traditional radio interference detection equipment,a method based on despreading cross-correlation is designed to obtain despreading gain by per-forming local pseudo-code cross-correlation on navigation spoofing interference,thereby achieving warning and detection of naviga-tion deception interference.The carrier cross-correlation method is used to extract the carrier phase differences of multiple-channel navigation spoofing signals,thereby enabling forward estimation of navigation deception interference and achieving the goal of de-tecting navigation deception sources.It fills the gap in the current mainstream radio interference detection equipment's inability to search for navigation deception interference sources and has practical engineering value.
