Abstract
Data of the SWARM-95 experiment, where intense internal waves on a stationary path led to coupling of acoustic source field modes, have been processed. The spectral-density localization domains, which are due to unperturbed and perturbed fields, are obtained using a double Fourier transform of interference pattern on a hologram. The interference patterns of these fields have been reconstructed by filtering these regions and applying double inverse Fourier transforms to them, which made it possible to reconstruct the unperturbed-waveguide transfer function and the time variability of the medium. The velocity of intense internal waves is estimated based on the recorded perturbed-field hologram.
