Acoustic doppler methods for remote measurements of ocean flows - a review

Abstract

The evolution of acoustic doppler methods for remote measurements of ocean flows has been briefly reviewed in historical perspective. Both Eulerian and profiling methods have been discussed. Although the first acoustic Doppler current meter has been developed in the early sixties, the progress in this area has been hampered for some time for lack of miniature computing devices and compatible signal processing techniques. Development in these areas led to gread advances in remote profiling of ocean currents using moored and ship-borne profilers incorporating three-, four-, and five- system
