Abstract
The main goal of the paper is to present application of the interferometric method for data processing in shallow water acoustic waveguides. The source sound field interference patterns are analyzed with 2D Fourier trasformation (hologram), within the framework of interferometric processing. Our purpose is to recover separately the interference patterns of sound field in unperturbed waveguide and its hydrodynamic perturbation by filtering in hologram domain.
