Time Synchronisation for Passive Bistatic HFSWR via Kalman‐Filtered Delay‐Locked Loop
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
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.

DOA estimation with extended sparse and parametric approach in multi‐carrier MIMO HFSWR
To obtain a higher angle resolution of multiple‐in multiple‐out high‐frequency surface wave radar (MIMO HFSWR) for direction of arrival (DOA) estimation with a limited number of antenna sensors, multiple working frequencies are proposed to enlarge the aperture of the virtual array of the MIMO HFSWR.
