Robustness of a correction method applied to a vertically deformed HFSWR on buoys [PDF]

open access: yes, 2009
International audienceThis paper presents two correction methods for vertical deformations of the receiving array belonging to HFSWR on buoys. The method inspired from Schelkunoff's representation is more robust to the deformation's uncertainty ...

First order sea clutter cross section for bistatic shipborne HFSWR [PDF]

open access: yesJournal of Systems Engineering and Electronics, 2017
This paper studies the development on the first order sea clutter cross section for bistatic high frequency surface wave radar (HFSWR). Based on the received first order electric field expression, a closed-form of cross sections is derived to account for the case of receiving antenna array being mounted on the shipborne platform.

Simultaneous Altitude and RCS Estimation with Propagation Attenuation in Bistatic HFSWR

open access: yes, 2013
High frequency surface wave radar (HFSWR) is traditionally unable to detect target altitude information. To simultaneously estimate the target altitude and radar cross-sections (RCS) with bistatic HFSWR, a novel estimation model is proposed with the ...

Deep Learning-Based Automatic Clutter/Interference Detection for HFSWR

open access: yes, 2018
High-frequency surface wave radar (HFSWR) plays an important role in wide area monitoring of the marine target and the sea state. However, the detection ability of HFSWR is severely limited by the strong clutter and the interference, which are difficult ...

Space-polarization Collaborative Suppression Method for Ionospheric Clutter in HFSWR

open access: yes, 2016
High Frequency Surface Wave Radar (HFSWR) is able to receive surface target and low-flying aircraft echoes at a long-distance, but it suffers severely from ionospheric clutter.
