Electromagnetic scattering measurements are discussed in the context of the validation of the triple diffraction coefficient of the uniform theory of diffraction. Explanations are provided to justify the sources of discrepancies between the theoretical expected values and the measured ones.
Measurement results to validate the UTD triple diffraction coefficient are presented. The experimental setup consists of multiple metallic objects, with triangular and rectangular profiles, located inside an anechoic chamber and illuminated by a sector antenna to reproduce a spherical wavefront with a transverse electromagnetic (TEM) incident field. Another sector antenna is moved vertically to collect...
Radio Frequency Tomography (see L. Lo Monte et al., “Radio Frequency Tomography for Tunnel Detection”, IEEE Trans. Geoscience and Remote Sensing, Vol. 48, No. 3, Mar. 2010, pp. 1128–1137) has been proposed as an attractive ground penetrating radar (GPR) application. RF Tomography uses MIMO sensors to detect targets for relatively wide regions, without requiring human presence on the field, by spreading...
We consider the problem of reconstructing the image of an object that is illuminated only by diffracted fields, i.e., there is no line-of-sight between the object and the source of illumination. The geometry of the problem consists of a partial metallic enclosure, i.e., an open metallic box, containing an object. The illumination is provided by a system of multiple transmitting and receiving antennas,...
