Abstract. Methods of near-field microwave diagnostics of subsurface inhomogeneities with the use of resonance probes based on cylinder capacitors are proposed. The first method uses the system of probes with different sounding depths; the second is based on measurements with a single probe at several altitude levels above the surface of the sounded medium. Method are based on the solution of obtained integral equations that represent expressions between capacity variations of probes that are determined by resonance parameters of probes and the spatial distribution of the complex permittivity of inhomogeneities in a medium.

Key words: tomography, holography, dielectric, inhomogeneous media, ònear-field microwave diagnostics.
