In this paper, we focus on an imaging procedure which retrieves the complex permittivity map of an investigation domain from electromagnetic scattered field measurements . The transmitter and the receiver are independently moved along two parrallel lines of finite extent. In such configuration, the antenna effects are of drastic importance. We propose thus a quantitative modeling of the antennas which does not require additional calibration process. The antennas model is completely incorporated in the inversion procedure and allows to recover tubes whose diameters are of the order of Abstract In this paper, we focus on an imaging procedure which retrieves the complex permittivity map of an investigation domain from electromagnetic scattered field measurements.
