Japan Tsunami Current Flows Observed by HF Radars on Two Continents [PDF]
Remote Sensing, 2011 Quantitative real-time observations of a tsunami have been limited to deep-water, pressure-sensor observations of changes in the sea surface elevation and observations of sea level fluctuations at the coast, which are essentially point measurements ...

First Order Sea Clutter Cross Section for HF Hybrid Sky-Surface Wave Radar [PDF]
Radioengineering, 2014 This paper presents a modified method to simulate the first order sea clutter cross section for high frequency (HF) hybrid sky-surface wave radar, based on the existent model applied in the bistatic HF surface wave radar.

International Journal of Antennas and Propagation, 2020 In high-frequency (HF) hybrid sky-surface wave radar, the first-order sea clutter broadening is severe under the action of ionospheric phase disturbance and bistatic angles. In this paper, a cascaded method is described to suppress the spread sea clutter.

A Directional Wave Spectrum Inversion Algorithm with HF Surface Wave Radar Network
Remote SensingIn high-frequency surface wave radar (HFSWR) systems, the retrieval of the directional wave spectrum has remained challenging, especially in the case of echoes from long ranges with a low signal-to-noise ratio (SNR).

Observation of Zenneck-Like Waves over a Metasurface Designed for Launching HF Radar Surface Wave [PDF]
International 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 ...
