Question

How does an acoustic doppler velocimeter work?​

Answer 1

Answer:

An acoustic Doppler velocimeter (ADV) operates by the principle of Doppler shift. This concept is illustrated by a simple example: if you are standing at a railroad crossing and a train blares its horn as it passes by, you hear the horn at a higher pitch as the train approaches, and then a lower pitch as it leaves.
