Imagerie microonde: influence de la polarimétrie du champ diffracté

Abstract : This thesis is devoted to the study of bidimensional polarimetric microwave imaging and consists of two parts. The first is dedicated on experimental studies for buried objects detection while the second presents the development of quantitative imaging algorithm. The work carried out in the first part deals with the realization of ultra-wide band antennas and the determination of their behaviour during polarimetric measurement. In the last case, many tests have been carried out and allow us to conclude on their qualities. In a second stage, we present a bidimensional imaging algorithm which is taking into account 2D-TM and 2D-TE polarizations. First, the development of an electromagnetic scattering algorithm is exposed. Its association with an inverse problem algorithm allows to generate the quantitative imaging algorithm. Then, many reconstruction configurations with isotropic or anisotropic homogeneous objects highlight its abilities.
