Quantitative Imaging With Incident Field Modeling From Multistatic Measurements on Line Segments

In this letter, we focus on an imaging procedure that retrieves the complex permittivity map of an investigation domain from electromagnetic scattered field measurements. The transmitter and the receiver are independently moved along two parallel lines of finite extent. In such a configuration, the antenna effects are of drastic importance. We propose thus a quantitative modeling of the antennas that 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 [(λ)/5].
