A feasibility study is reported on the development of a coherent acoustic Doppler current profiler with spatial resolution and range comparable with those of commercially available incoherent systems, but with much smaller velocity measurement variance. This improvement will reduce required averaging times, thus permitting the observation of short-time-scale currents (i.e., internal wave breaking). Several strategies have been analyzed and tested including the transmission of coded acoustic pulses combined with coherent signal-processing techniques. This approach may allow the measurement of watermass velocities with high accuracy without the range limitations of conventional pulse-to-pulse coherent systems due to velocity ambiguity and pulse-to-pulse decorrelation.
