PHW-2M-01T
Doppler Effect ADCP Piezoelectric Transducers Custom Underwater Acoustic Transducer
1. Introduction
An acoustic Doppler current profiler (ADCP) is a hydroacoustic current meter similar to a sonar, used to measure water current velocities over a depth range using the Doppler effect of sound waves scattered back from particles within the water column.
An Acoustic Doppler Current Profiler (ADCP) measures ocean currents using the principle of “Doppler shift.” If you have heard a train whistle in the distance, you are familiar with Doppler effect. As the train gets closer, the whistle pitch gets higher. As the train moves away, the whistle pitch gets lower. The change in pitch is proportional to the speed of the train.
