Abstract. First investigation results are given for a new method of pulse diagnostics of 3D distributions of complex permittivity of subsurface dielectric inhomogeneities. This diagnostics is based on the solution of the near-field inverse scattering problem by data of 2D scanning with the transceiver system. In this paper a solving algorithm is proposed for this inverse scattering problem, and results of tomography and holography of test subsurface targets in the near field zone of the probing signal are demonstrated.

Key words: tomography, holography, dielectric, inhomogeneous media, scattering of microwave radiation.
