Microwave imaging of penetrable scatterers using deformable mirror

Active microwave imaging involves reconstruction of the spatial distribution of the electrical property inside the object of interest using multiview field measurements. In this paper, a microwave tomography technique employing a continuously deformable mirror and a single fixed transmitter is discussed as an alternative to the conventional technique that uses multiple transceiver antennas. The deformable mirror tomography is capable of generating a multitude of field measurements necessary to recover the spatial distribution of the unknown permittivity inside the penetrable dielectric object. Preliminary inversion results obtained using 2-D numerical model discussed in this paper demonstrate the feasibility of the proposed microwave imaging method.
