✦ Synopsis
This article deals with short-range active microwave imwritten in terms of suitable Green's functions. The moment aging. In particular, a 3-GHz imaging system based on a modulated method [8] is then used to discretize the continuous model assumscattering technique is described. By using a probe made of an array ing the dielectric parameters as well as the internal field to be of (passive) dipoles rotating around a test area, it is possible to meaconstant inside each subdomain. An efficient solution of the probsure the field scattered by a long cylinder under approximately translem usually require to include a priori information on the object, verse-magnetic illumination conditions. Moreover, some considerawhereas unconstrained reconstructions in general fail owing to tions are made concerning the relationship for the modulated scatterthe ill-conditioning of the problem, especially for highly coning techniques. Finally, some preliminary experimental results are trasted bodies.
