High frequency (HF) radar systems are useful for measuring the velocity of sea surface currents. Besides the ecological and economic importance of being able to accurately measure currents, the US Coast Guard uses HF radar to make decisions involved in search and rescue operations. Currently, 5 MHz or long-range HF radar systems output radial vector files that are calculated using a 180-minute averaging...
High Frequency radar has been operational with the US Coast Guard since May 2009. The long-range SeaSonde is a key component of the national HF radar network. Default SeaSonde processing on long-range systems only captures 92% of the M2 tidal current velocity and hence 85% of the tidal energy due to a 180-minute averaging time. Reducing this averaging time would help improve the surface current measurements...
The U.S. Integrated Ocean Observing System (IOOS®) partners have begun an effort to extend the use of high frequency (HF) radar for U.S. Coast Guard (USCG) search and rescue operations to all U.S. coastal areas with HF radar coverage. This project builds on the success of an IOOS and USCG-supported regional USCG search and rescue product created by Applied Science Associates (ASA), Rutgers University...
