Abstract
The article presents the results of the application of the method of t wo-dimensional adaptive extrapolation (a modification of the Gershberg -Papoulis algorithm) for attaining superresolution of the image of def ects reconstructed from multifrequency numerical acoustic holograms. I n experiments with the processing of images of models of point and bul k defects transverse resolution was quadrupled and longitudinal resolu tion doubled.
