This paper presents a tomographic reconstruction algorithm based on inverse of a set of integral equations relating to Fourier transform of backscattered field data with sought object function at each excitation frequency. Probed structure is a part

Diffraction tomography provides a good method for reconstructing cross-section images of weakly scattering dielectric objects. The Born and Rytov approximations are well-known approximations for the first-order diffraction tomography method. In this

The new approach to the solution of a problem of the microwave image reconstruction of the subsurface objects is offered in the present work. Necessity of the complex amplitude measurement of electromagnetic field is excluded in a point on a direct l

The detection and imaging of concealed objects like spy cameras, eavesdropping spy devices behind or inside a wall are important problems. As electronic technology is developed, dimensions of these devices are being decreased. For this reason, in thi

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 a
One of the most important problems for imaging of buried objects by the microwave tomography method is reflection from the surface. Experiments show that the level of surface reflection is very large. Because of this large reflection from surface, it

The described systems combine the possibilities of tomograph operating "on passage" as well as tomograph operating in a regime of subsurface measurements. It is shown that if the incident wave is arranged at the Brewster angle, the surface reflection
