Ocean environment Noise directivity estimate base

Yu-lu CAO


The Ocean environment noise directivity is a base for Background noise inhibition in signal processing. We do | about for Method To the directivityanalyse in ocean Environment noise field and anisotropic token base on single Vector hydrophone . analysed , Relationship between the background Noise directivityand background Noise inhibition Ability by Vector hydrophone . Do experiment in on Method of the level Directivity analyse Base On data a Ocean envir ­ onmentNoise in North yellow Sea By- Vector hydrophone. There are two results that one is level Anisotropy degree differ ­ ence In Ocean Environment Noise field is prominence in difference Frequency, Other ? The inhomogeneity of This Ocean en ­ vironment noise level directivity is prominence In some Special frequency, Whichis the same as Ship distributing .
