Estimating the parameters of the seabed using the spatial characteristics of ocean ambient noise [PDF]
MATEC Web of Conferences, 2019 When solving traditional underwater problems, the boundary condition is always used to calculate the sound field. In practice, however, it is hard to get the boundary conditions of the seabed. So geoacoustics inversion is needed to acquire the parameters
