Analysis of the characteristic of vector hydrophone's inner sound field

Abstract

Aiming at spherical co-oscillating vector hydrophone, this paper considered it as an elastic sphere vibrating freely underwater, and analyzed the characteristic of vector hydrophone's inner sound field, due to an incident train of plane wave. This paper used the finite element simulation software to analyze the vibration modes of elastic sphere, and summarized the influence of these results on the receptivity of vector hydrophone. These analysis results have certain reference function for the optimization of design of new type vector hydrophone.
