Remote Velocity Measurements from Doppler Sonar,
Abstract
Remote measurements of the oceanic velocity field can be obtained with Doppler backscattering sonars. While Doppler scattering methods have been used for the past 30 years to make local flow measurements, it is only recently that their remote ranging capabilities have been seriously exploited. Currently, velocity measurements have been made to a range of approx. or equal to 1.5 km, with 20 m range resolution and 1 cm/sec velocity precision, using a sonar mounted on the Research Platform Flip. In this paper Doppler sonar principles are briefly introduced and examples of these data are presented.
