Abstract - -
HF-radars have been developed to map surface currents off shore by means of
land-based stations. Presently available radar systems use frequencies between
25 MHz and 30 MHz and allow a spatial resolution of some 1 km
and ranges of up to 50 km.
This paper reports on the experience with a ship-borne HF radar
and discusses problems which arise for the azimuthal resolution on a metal
ship, the correction for the ship's speed and limitations due to
pitch-and-roll motions. Current measurements during cruises to the North
Atlantic are presented. It has been found that with the support of the
satellite-supported Global Positioning System (GPS), the ship-borne HF
radar can measure surface current velocities with an accuracy of some
