| Résumé : |
|
In this paper, laboratory scale measurements of long-range across-slope propagation of broadband pulses in a shallow-water wedgeshaped environment with a sandy bottom are reported. The scaled model was designed to study the three-dimensional (3D) acoustic field in the presence of only a few propagating modes. The recorded time series exhibit prominent 3D effects such as mode shadow zones and multiple mode arrivals. Inspection of the spectral content of the time signals gives evidence of intra-mode interference and frequency dependence of the mode cut-off range in the across slope direction. |
