Quality Control for Ocean Current Measurement Using High-Frequency Direction-Finding Radar
Remote Sensing, 2023 High-frequency radars (HFRs) are important for remote sensing of the marine environment due to their ability to provide real-time, wide-coverage, and high-resolution measurements of the ocean surface current, wave height, and wind speed.

The Turbulence Properties of 150‐km Echoes in the Lower Ionosphere
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract The valley region ionosphere spans from approximately 120–200 km in altitude, and hosts a wide range of plasma, neutral, and solar interactions that create and maintain the ionosphere. In this region a ubiquitous and mysterious source of radar echoes called “150‐km echoes” has been observed since the 1960s.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.Abstract Parker Solar Probe has been proven as instrumental for the observation of young solar wind. During the encounters E‐07 and E‐08, PSP recorded the core plus beaming protons crossing the heliospheric current Sheet region. When the observed PSP data is plotted in the temperature ratio versus parallel beta space, it is found that the occurrence ...

Enhancing Low‐Latitude Ionospheric Irregularity Prediction With Generalized Linear Models
Space Weather, Volume 24, Issue 3, March 2026.Abstract The ionosphere poses challenges for accurate forecasting due to its complexity and variability. Irregularities in the lower ionosphere are influenced by local time, season, geographic location, solar activity and space weather, complicating precise predictions.

Surface Clutter Suppression Techniques for Ice Sounding Radars: Analysis of Airborne Data [PDF]
, 2008 For the ice sounding of Antarctica from space, a P-band radar at 435 MHz is the only option which complies with present ITU regulations. At this frequency the ice surface cannot be considered smooth, leading to high ambiguous returns.

Research on Polarization Cancellation of Nonstationary Ionosphere Clutter in HF Radar System [PDF]
International Journal of Antennas and Propagation, 2015 Oblique projection polarization filter (OPPF) can be applied as an effective approach for interference cancellation in high-frequency surface wave radar (HFSWR) and other systems. In order to suppress the nonstationary ionosphere clutter further, a novel OPPF based clutter suppressing scheme is proposed in this paper. The polarization and nonstationary
