Abstract
In this work, we extend the direct method in 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.
