Time Synchronisation for Passive Bistatic HFSWR via Kalman‐Filtered Delay‐Locked Loop
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper proposes a per‐chirp time synchronisation method, FLOS‐Kalman‐DLL, for passive bistatic high‐frequency surface wave radar (HFSWR) operating under the coexistence of clock drift and atmospheric impulsive noise. The method combines fractional lower‐order statistics with a Kalman‐filtered delay‐locked loop to achieve sub‐sample synchronisation ...

Deghosting method for cross localization in distributed high frequency surface wave radar
The Journal of Engineering, Volume 2024, Issue 11, November 2024.To address the ghosts emerging during the cross localization in a novel distributed high frequency surface wave system, a multi‐stage deghosting method is utilized, which is based on the geometric characteristics, the velocity features, and the motion features of the targets across multiple frames.
