Simultaneous reconstruction of sources and scatterers in a
three-dimensional stratified ocean waveguide
Abstract
In this work, we extend the direct method in [26] to identify the
marine sources and scatterers simultaneously from the far-field pattern
in a stratified ocean waveguide. The proposed approach is essentially
direct and does not involve any optimizations, solution procedures or
matrix inversions, thus computationally rather efficient and simple.
Some numerical simulations are carried out to exhibit the robustness and
effectiveness of the proposed method in the reconstruction procedure.
The extended direct method can not only identify the sources in
different locations but also can reconstruct the scatterers in different
shapes and positions, therefore it can be considered as an efficient
numerical approach for providing reliable estimates of the marine
inhomogeneities in the marine acoustics.
