What is CODAR ?

The HF-radar which has been used until 1996 at the University of Hamburg was based on CODAR (COastal raDAR). This old design has been introduced in 1977 at NOAA by D.E.Barrick and is different from the actual SeaSonde. The old CODAR uses electromagnetic waves of about 10 m length, which interact with ocean waves of 5 m length. As one radar can only measure the radial component of the surface current, a minimum of two HF-radars has to be installed. The systems are set up on the ground close to the sea and have a working range of up to 50 km depending on the salinity of the water and the sea state. This is an example for surface currents measured by CODAR in the German Bight. Current vectors are shown on a 3x3 km grid.
In 1996 the University of Hamburg designed a new HF-radar to allow measurements of ocean wave directional spectra using the University of Sheffield [UK] algorithms. The new HF-radar is named WERA (WEllen RAdar).
