Abstract :
The SW2000 Doppler Current Profiler utilizes an FFT (fast Fourier transform) process to extract the Doppler shift from the received reverberation signal. The Doppler received in each depth cell on the various beams is then resolved to provide the three U,V and W current vectors. This paper discusses some of the enhancements and features of this process designed to assure highest accuracy and maximum depth performance from a ship borne profiler
