Abstract:: The results of a numerical experiment on approbation of the holographic method of mode selection in a shallow water area against the background of intense internal waves, which cause interaction of waves of a broadband sound source. An analysis of the resolution of modes and the restoration of their parameters has been carried out. It is shown that the effects of mode interaction do not lead to the loss of the identity of the mode characteristics of the signal.

Keywords: shallow sea, holographic interferometry, mode extraction, intense internal waves, mode interaction, moving sound source
