On the Use of SuperDARN Ground Backscatter Measurements for Ionospheric Propagation Model Validation
Space Weather, Volume 22, Issue 9, September 2024.Abstract Prior to use in operational systems, it is essential to validate ionospheric models in a manner relevant to their intended application to ensure satisfactory performance. For Over‐the‐Horizon radars (OTHR) operating in the high‐frequency (HF) band (3–30 MHz), the problem of model validation is severe when used in Coordinate Registration (CR ...

A New Generation of HF Surface Wave Radar [PDF]
International audienceA primary function of a radar is to monitor a given area. For surface radars, the monitored area is limited by the horizon due to the Earth's curvature. To overcome this limitation, several concepts of HF Over The Horizon Radar (OTH-

The HF Surface Wave Radar WERA. Part II: Spectral Analysis of Recorded Data [PDF]
, 2010 This paper covers the second part of the analysis of data recorded by the surface wave (SW) over-the-horizon (OTH) WEllen RAdar (WERA). Data were collected by two WERA systems, on May 13th 2008, during the NURC experiment in the Bay of Brest, France. The

Geophysical Research Letters, Volume 51, Issue 16, 28 August 2024.Abstract Monitoring the generation and movement of equatorial plasma bubbles (EPBs) in a large longitude region is crucial important for better understanding their day‐to‐day variability. Using the newly developed Low lAtitude long Range Ionospheric raDar (LARID) at Dongfang (19.2°N, 108.8°E, dip lat.

Detection and Classification of Sporadic E Using Convolutional Neural Networks
Space Weather, Volume 22, Issue 1, January 2024.Abstract In this work, convolutional neural networks (CNN) are developed to detect and characterize sporadic E (Es), demonstrating an improvement over current methods. This includes a binary classification model to determine if Es is present, followed by a regression model to estimate the Es ordinary mode critical frequency (foEs), a proxy for the ...

Adaptive waveform algorithms for HF-OTH skywave radar [PDF]
, 2011 Since 1960, Over the Horizon radars have been studied; they fall into two types: Sky-wave and Surface-wave radar systems, classified as a function of electromagnetic waves propagation mode. The HF-OTH skywave performance strongly depends on several space-
