Abstract - -
HF radar is a remote sensing technique for measuring surface currents
and ocean wave directional spectra.
This paper describes the extension of a land based system to enable surface
current measurements from a slowly sailing ship.
To compensate the ship's motion, the Global Positioning System (GPS)
has been used.
Due to additional error sources compared to the land based system,
the accuracy of measured currents is slightly reduced from 2 to 5 cm/s
to 3 to 10 cm/s. An algorithm to calculate the surface current from two or
more measured radial components is presented.
