Abstract :
Considers the reconstruction of inhomogeneity distribution in oceanic waveguides. The restoration of Fresnel images by one antenna (pseudo-vision) and two remote arrays (binocular scheme) using special spectral filtration is analyzed in detail. Common processing of pseudo-images from different projections is used to increase the spatial resolution. The tomography algorithm is tested on simulated objects. Finally, reconstruction images are displayed
