| description | The invention discloses an underwater acoustic measurement device and method based on angular motion. The method comprises the following steps: 1) placing an inertial body in a water area to be measured, respectively arranging an angular motion sensor on one or more surfaces of the inertial body, and measuring the angular acceleration beta of each surface in a corresponding direction when the inertial body is disturbed by water flow; the inertia body is an inertia cube, the mass of the inertia cube is m, and the side length of the inertia cube is L; (2) when the inertial body is disturbed by water flow, each angular motion sensor sends measured angular acceleration beta in the corresponding direction to a data processing unit; and (3) the data processing unit obtains the underwater sound pressure difference delta P in the corresponding direction according to calculation. According to the invention, sensing of the water sound is completed based on angular motion of the inertial body, sensitivity to the water s |
