Acoustic Scattering from Circular Cylinder with Neighborhood Structure

Hydrophone system has necessarily additional structures to resist installation and operation for military usage. In this paper, we assume that the hydrophone is a rigid circular cylinder and the neighborhood structure is a perfect reflector. Scattering fields by hydrophone and neighborhood structure are investigated to use a boundary element analysis program, SYSNOISE, which has an acoustic analysis capability. The pressure fields around circular cylinder with respect to the angle are evaluated.
