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.
