Abstract

We develop a method automatically identifying peak frequencies in the sea echo Doppler spectrum measured by DBF Marine Rader system to estimate coastal surface currents, and then evaluate the accuracy and Iimitation of this method. The velocities from the Radar system estimated with this method are compared well with near-surface data with ADCP. The processing time of this method is short in about 40 seconds.These results suggest that this method allows one to estimate remotely coastal surface current in real timeusing DBF Marine Radar system.
