Motion Parameter Identification and Motion Compensation for Shipborne HFSWR by Using the Reference RF Signal Generated at the Shore [PDF]

Remote Sensing, 2020
The shipborne high-frequency surface wave radar (HFSWR) platform produces six degrees of freedom (DOF) motion at sea, which affects the performance of radar target detection and remote sensing of ocean surface dynamics parameters. Motion compensation can

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

IET 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 ...

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

IET 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

Remote 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.

Application of joint domain localised matrix CFAR detector for HFSWR

The Journal of Engineering, Volume 2019, Issue 21, Page 8134-8137, November 2019., 2019
Target detection is one of the most important parts of high‐frequency surface wave radar (HFSWR) signal processing, to find targets in noise or clutter and obtain targets’ information. However, some factors, such as the influence of clutter and the increase of detection range, will degrade the signal‐to‐clutter ratio (SCR). In the low SCR scenario, the

A Novel Main‐Lobe Cancellation Method Based on a Single Notch Space Filter and Optimized Correlation Analysis Strategy

International Journal of Antennas and Propagation, Volume 2019, Issue 1, 2019., 2019
The high‐frequency hybrid sky‐surface wave radar (HFSSWR) is a new kind of over‐the‐horizon radar system. Combining the advantages of both the sky wave radar and the surface wave radar, HFSSWR has drawn much attention in recent years. But the new system also brings new challenges.

Weak Target Detection within the Nonhomogeneous Ionospheric Clutter Background of HFSWR Based on STAP

International Journal of Antennas and Propagation, Volume 2013, Issue 1, 2013., 2013
High Frequency Surface Wave Radar (HFSWR) can perform the functions of ocean environment monitoring, target detection, and target tracking over the horizon. However, its system′s performance is always limited by the severe ionospheric clutter environment, especially by the nonhomogeneous component.

Research on Fast Deployment Algorithm for Ocean Environment Monitoring Based on Ship‐Borne High‐Frequency Surface Wave Radar

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
Our method introduces a minimum resource parameter model and leverages a grid search algorithm integrated with a dual‐base spatial coverage model to identify the optimal deployment configuration. The results demonstrate that our approach significantly reduces computational time while maintaining high coverage accuracy, making it suitable for real‐time ...
