Introduction to Coastal HF Maritime Surveillance Radars
Polish Maritime Research, 2019 This paper presents the main technical characteristics and working performances of coastal maritime surveillance radars, such as low-power High-Frequency Surface Wave Radars (HFSWR) and Over the Horizon Radars (OTHR). These radars have demonstrated to be

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.

DOA estimation with extended sparse and parametric approach in multi‐carrier MIMO HFSWR
The Journal of Engineering, Volume 2019, Issue 21, Page 7810-7814, November 2019., 2019 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.

Array self‐calibration for sky‐wave over‐the‐horizon radar with gain‐phase errors
The Journal of Engineering, Volume 2019, Issue 19, Page 6192-6195, October 2019., 2019 This study proposes a novel algorithm for sky‐wave over‐the‐horizon (OTH) radar array self‐calibration with angle‐independent gain‐phase errors. The proposed method exploits backscattered echo from an ionised meteor trail, which can be considered as disjoint sources of opportunity for their spatial and temporal fluctuations during coherent processing ...
