Shipborne HFSWR Target Detection in Clutter Regions Based on Multi-Frame TFI Correlation

open access: yesRemote Sensing, 2022
High-frequency surface wave radar (HFSWR) is an important marine monitoring technology, and this new regime of radar plays an important role in large-scale, continuous early-warning monitoring at sea. In particular, shipborne HFSWR has wider applications

Blind time‐domain motion compensation for synthetic Doppler spectra obtained from an HF‐radar on a floating platform

open access: yesIET Radar, Sonar &Navigation, Volume 17, Issue 4, Page 571-578, April 2023., 2023
The article considers the case of a monostatic HF radar configuration where the transmitting antenna is on a floating platform while the receiving antenna is fixed. The proposed non‐linear optimisation‐based method in this article is able to successfully estimate the parameters of motion of the floating platform without prior knowledge of them and is ...

An Evaluation Method of Ship‐Tracking Algorithms for High‐Frequency Surface Wave Radar considering High Maneuvers Generated by the MMG Model

open access: yesJournal of Engineering, Volume 2023, Issue 1, 2023., 2023
Thelong‐distance coverage of high‐frequency surface wave radar (HFSWR) has promoted it as an enormous means for ship monitoring on the country’s maritime territory. Since it is a primaryradar, noncooperative targets can also be detected. However, this radar also has a shortcoming of low spatial and temporal resolutions due to the narrow available ...

Multi‐target pair‐matching method based on angle information in transmit/receive‐receive synergetic High Frequency Surface Wave Radar

open access: yesIET Radar, Sonar &Navigation, Volume 16, Issue 7, Page 1188-1197, July 2022., 2022
Abstract In the past few decades, the target location methods in transmit/receive‐receive (T/R‐R) synergetic High Frequency Surface Wave Radar (HFSWR) have received extensive attention from the signal processing community. However, there are few studies on the method of parameter pair‐matching for multi‐target scene.

Coast–Ship Bistatic HF Surface Wave Radar: Simulation Analysis and Experimental Verification

open access: yesRemote Sensing, 2020
The coast−ship bistatic high-frequency surface wave radar (HFSWR) not only has the anti-interference advantages of the coast-based bistatic HFSWR, but also has the advantages of maneuverability and an extended detection area of the shipborne HFSWR.

Impacts of Auroral Precipitation on HF Propagation: A Hypothetical Over‐the‐Horizon Radar Case Study

open access: yesSpace Weather, Volume 19, Issue 12, December 2021., 2021
Abstract Over‐the‐horizon radar (OTHR) systems operating in the high‐frequency (HF) band (3–30 MHz) are unique in their ability to detect targets at extreme ranges, offering cost‐effective large‐area surveillance. Due to their reliance on the reflective nature of the ionosphere in this band, OTHR systems are extremely sensitive to ionospheric ...

Linear Frequency Modulation and Orthogonal Code Modulation for Co-Located Multiple-Input Multiple-Output High-Frequency Surface Wave Radar

open access: yesRemote Sensing, 2023
A high-frequency surface wave radar (HFSWR) is the only sensor that provides inexpensive surveillance for up to 200 nautical miles (NM) of the exclusive economic zone in the 3–5 MHz band. However, because of its long wavelength, its angular resolution is

Comparative Study on Chaos Identification of Ionospheric Clutter From HFSWR

open access: yesIEEE Access, 2019
In addition to target echoes, high frequency surface wave radar (HFSWR) receives sea and ionospheric clutter. Among these clutters, the ionospheric clutter is dominant and significantly affects the detection performance of HFSWR, particularly when the ...
