Modeling of microwave images of buried cylindrical objects

Tomographic methods of image reconstruction of two-dimensional cross-sectio ns of volumetric in millimeter wavelengths band are suggested and considere d. It is shown that in the frequency band under consideration, the images of i nvestigated objects may be obtained by first-order diffraction tomography m ethod (Born, Rytov or high frequency approximation of the first-order for s cattered electromagnetic field).
