Study on the influence of curved-surface baffle on the receiving performance of vector hydrophone
摘要
Abstract
To address the interference caused by the acoustic scattering of a curved-surface baffle on the perfor-mance of a vector hydrophone,the acoustic scattering field of a rigid curved-surface baffle with a parabolic distri-bution was investigated.Expressions for the sound pressure and particle velocity in the baffle's vector sound field were derived using the Kirchhoff approximation combined with boundary conditions.The spatial distribu-tion characteristics of the scattered sound field were analyzed,and the influence of baffle scattering on the direc-tivity of the vector hydrophone was examined.The correctness of the calculation method for the scattered sound field was verified through experiments.The results show that owing to the scattering effect of the curved-surface baffle,the amplitudes of the sound pressure field and particle velocity field are primarily distributed in the cen-tral axis region,forming a left-right symmetric interference structure.Changes in the structural parameters of the baffle have little effect on directivity at low frequencies;however,at high frequencies,they sharpen the directiv-ity and introduce sidelobes.The findings of this study provide theoretical support for the practical engineering application of vector hydrophones.关键词
