“…Beyond the radar architecture, the processing of experimental data plays an important role. In most processing approaches, the goal is to localize hidden targets or produce a qualitative image of the indoor scenario [1][2][3][4][5][6], returning information about the target's shape or the presence of interfaces. Accurate forward scattering approaches may improve the reconstruction capabilities of radar surveys.…”

The imaging of dielectric targets hidden behind a wall is addressed in this paper. An analytical solver for a fast and accurate computation of the forward scattered field by the targets is proposed, which takes into account all the interactions of the electromagnetic field with the interfaces of the wall. Furthermore, an inversion procedure able to address the full underlying non-linear inverse scattering problem is introduced. This technique exploits a regularizing scheme in Lebesgue spaces in order to reconstruct an image of the hidden targets. Preliminary numerical results are provided in order to initially assess the capabilities of the developed solvers.

Through-the-wall imaging (TWI) is an emerging technology to help human see through walls in various critical situations. Adapting from Radar technology, TWI could be performed through beamforming of an array of ultrawide band (UWB) sensors. One of the challenges in designing a beamformer is to achieve high resolution and low clutter sensitivity. The resolution can be improved by increasing the aperture length at the expense of an increase in clutter sensitivity. An improved version of the standard delay-and-sum (DAS) beamformer, or EDAS has been developed and tested to suppress the clutter. An experiment has been performed and then images were reconstructed using DAS and EDAS. Comparison of the Target Clutter Ratio (TCR) of the images shows that EDAS had improved the TCR significantly.
