Abstract :
The analysis and design of an underwater acoustic velocimeter employing a high-frequency CW resonance technique is presented. It is shown that such an instrument achieves high sensitivity and resolution and is believed to be relatively immune to the effects of turbulence. The analysis is illustrated by a prototype design giving a sensitivity of 84 Hz/ft/s of sound velocity.
