| Abstract: | Ambient noise analysis using pressure and particle velocity combined processing is introduced in this paper. A novel kind of combined sensor is used to gather underwater ambient noise data, the main idea is to split the ambient noise filed into anisotropic and isotropic parts, so that the componeats of the ambient noise filed and the properties of them can be studied to a greater extent. |
