HF radars are a unique and powerful tool for measuring surface currents. They provide an unparalleled window into the spatial variations of near-surface currents. But oceanographers who are more accus...
Experience With Shipborne Measurements of Surface Current Fields by HF Radar
Shipborne Measurements Surface Current Fields HF Radar
2015/8/10
Oceanographic research using HF radar techniques started in Germany in 1980 by adopting NOAA's CODAR (Coastal Ocean Dynamics Applications Radar), which has originally been introduced by Barrick et al....

it takes more
than the Adcp itself, however, to yield good
current measurements. The end result depends
on how and where the sonar is installed; on
the quality of ancillary information includi...
