A RIGIDLY MOUNTED UNDERWATER ACOUSTIC INERTIAL VECTOR SENSOR

摘要

An underwater acoustic sensor (10) is designed for attachment to a rigid or semi-rigid mounting structure (24). The sensor include outer casing (14) and a secondary casing (18) spaced therefrom. A compliance layer (16) is disposed between the inner surface of t outer casing and the outer surface of the secondary casing. An inner sensor support is designed to attach to the mounting structure is spaced from the inner surface of the secondary casing. A plurality of sensor elements are disposed between and interconnect the inner surface of the secondary casing and the sensor support.
