Abstract
Currents induce changes in the travel time of an acoustic signal. This effect can be exploited to measure current velocity. Theoretical calculations are compared with experimental measurements over a 33-km range. Equations and a system layout are presented for measurement of current velocity when the sound speed is spatially variable. Simplifications that are possible when the current direction is known and/or the sound speed is constant are discussed.
