Learn About Sea Surface Currents and How They Are Measured
A transmitter broadcasts a frequency modulated radio frequency pulse at 2Hz (two pulses per second). The Doppler shifted return signal (sea echo) is detected with a compound cross loop/monopole receive antenna and the signal is processed into estimates of surface current speed and direction and wave heights, period and direction.
