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...
The proliferation of HF radar networks around the globe has made them a vital component of the ocean observing endeavor. There are approximately thirty-four nations with oceanographic HF radar networks, eight of which have over 10 radar stations in their network. Providing high quality measurements for sustained periods of time is of the utmost importance. The global HF radar network has been established...
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...
There are approximately 300 High Frequency (HF) radars deployed around the globe making real time measurements of the surface currents in the coastal ocean. In the United States, the HF radar network within the Mid Atlantic Regional Association Coastal Ocean Observing System (MARACOOS) became operational with the United States Coast Guard in May 2009. This model was expanded nationally and the Integrated...
