Vector Characterization of the Sound Field in the Sonar Domes

The research direction of this paper is based on the acoustic environment of underwater unmanned vehicle (UUV) outboard platform, with the help of finite element simulation, using COMSOL to model the outboard platform equipped with vector array, to study the noise vector characteristics inside the deflector shroud under the influence of flow noise at a certain air speed, and to analyze the changes in the shape and size of the deflector shroud, as well as the changes in the vector acoustic characteristics caused by the changes in the placement position of the vector hydrophones, in order to obtain the optimal installation position and selection of the size of the vector hydrophones. To obtain the optimal installation position of the vector hydrophone and the size of the fairing.
