Abstract

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, which belong to an RF Tomography system (L. Lo Monte, D. Erricolo, F. Soldovieri, M.C. Wicks, “Radio Frequency Tomography for Tunnel Detection,” IEEE Trans. Geoscience and Remote Sensing, Vol. 48, No. 3, Mar. 2010, pp. 1128-1137).
