An acoustic correlation current profiler (ACCP) system for obtaining vertical profiles of current velocities to ranges of approximately 1500 m is discussed. A single transmitter and a spatial array of eight receivers arranged in a certain geometry is used to measure water mass displacement from receiver array cross correlation functions. Test data from a shallow water ACCP operating at 76.8 kHz is presented and compared to model predictions as well as to velocity profiles obtained simultaneously during the tests from an adjacent acoustic Doppler current profiler. Predicted performance for a lower frequency, deep water unit is presented.
