A Geometric Barycenter-Based Clutter Suppression Method for Ship Detection in HF Mixed-Mode Surface Wave Radar

open access: yesRemote Sensing, 2019
The nonhomogeneous clutter is a major challenge for ship detection in high-frequency mixed-mode surface wave radar. In this paper, a geometric barycenter-based reduced-dimension space-time adaptive processing method is proposed to suppress the clutter ...

Observation of Zenneck-Like Waves over a Metasurface Designed for Launching HF Radar Surface Wave

open access: yesInternational Journal of Antennas and Propagation, 2016
Since the beginning of the 20th century a controversy has been continuously revived about the existence of the Zenneck Wave. This wave is a theoretical solution of Maxwell’s equations and might be propagated along the interface between the air and a ...

High-Speed Target Tracking Method for Compact HF Radar

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Compact high-frequency (HF) surface wave radar can be used for remote sensing of sea surface dynamic parameters, such as winds, waves, and currents, as well as hard targets, such as ships and low-altitude aircrafts.
