Simultaneous HF‐radar and DMSP observations of the cusp

Geophysical Research Letters, 1990
The Geospace Environment Modeling (GEM) Program is directed toward modeling the coupled solar wind/magnetosphere/ionosphere system. The inter‐calibration of ground‐based observations of the ionosphere and satellite observations has been identified as an essential step in tying together the data to produce a global picture of geospace.On October 10,1988

A bistatic HF radar for surface current mapping

IEICE Electronics Express, 2010
This paper proposes a bistatic High Frequency Surface Wave Radar (HFSWR) system for ocean current mapping. This system is composed of two remote sites. Both receive backscattered echoes as well as bistatic echoes transmitted by the other. An experiment was conducted on the coast of the North China Sea during January 2010, which proved effectiveness of ...

Improving Coastal Circulation Using HF‐Radar Surface Currents

Earth and Space Science
In an attempt to improve the model‐derived coastal circulation around India, we explore three different frameworks to assimilate surface currents from HF‐Radars into an ocean model for the Indian Ocean.

HF Radar Sea-echo from Shallow Water

Sensors, 2008
HF radar systems are widely and routinely used for the measurement of ocean surface currents and waves. Analysis methods presently in use are based on the assumption of infinite water depth, and may therefore be inadequate close to shore where the radar ...

Validating HF Radar Current Accuracy via Lagrangian Measurements and Radar-to-Radar Comparisons in Highly Variable Surface Currents

Remote Sensing
The validation of HF radar systems remains an area with significant scope for advancement, particularly in terms of linking data quality with system operational parameters, fully utilizing the potential of redundant data (e.g., overlapping radial ...

Application of HF Radar in Hazard Management

International Journal of Antennas and Propagation, 2016
A review is given of the impact that HF radars are having on the management of coastal hazards. Maps of surface currents can be produced every 10–20 minutes which, in real time, improve navigation safety in restricted areas commonly found near ports and ...

Wind Speed and Direction Mapping with HF Radar

Remote Sensing
HF radar systems are used in many parts of the world as a part of operational coastal ocean observing systems. Their primary product is surface current mapping from the coast to a range determined by radio frequency and environmental conditions. Initiatives to promote their use for wave measurement are now being developed.

Ionospheric Corrections for Space Domain Awareness Using HF Line-of-Sight Radar

Remote Sensing
As the near-Earth space domain becomes increasingly congested, the field of space domain awareness (SDA) has risen in importance and motivated the use of non-traditional sensors.

The European HF Radar inventory

, 2016
The inventory of the different HF radar systems operating in Europe has been gathered thanks to the survey launched by the EuroGOOS HFR Task Team, in the framework of INCREASE and JERICO-NEXT projects. We are very grateful to all the people who kindly provided the information of their radar and related activities.
