Inversion algorithm and measurement system for microwave tomography of buried object

The detection and identification of buried inhomogeneities using electromag netic waves are of crucial importance for many applications. The paper deal s with reconstructed images from measurements using an inversion qualitativ e algorithm for microwave tomography. The algorithm is based on diffraction tomography for detecting and locating buried objects. The backscattered fi eld is measured at different frequencies over a probing line above or in co ntact with the soil at different receiver locations and for different posit ions of a transmitting antenna (multistatic configuration). The reconstruct ion algorithm processes the backscattered field generated by the buried inh omogeneities and incorporates the incident near-field distribution transmit ted in the soil by the broadband antenna. Tomographic reconstructions of bu ried objects are presented for a situation of practical interest using bow tie antennas in tilt: frequency band [0.3 - 1.3] GHz.
