Methods of improving of the subsurface objects images reconstructed by the tomography process

A possibility of an application of the tomography method and spectrum filtering for the images reconstruction of the cross-sections of different inhomogeneities, which are taking place under plane surface of a medium, has been studied. The spectral approach, use of the information containing in near field of scattering object, opportunity of use of the tomography algorithm in a case of strongly absorbing environments have allowed essentially to improve quality of the restored images and have expanded the application area of the subsurface tomography. Obtained results can find application in practice at designing of the tomography systems used for visualisation of the subsurface targets.
