Through-the-Wall Imaging is emerging as an affordable sensor technology supporting a variety of applications, such as
surveillance and reconnaissance, emergency rescue, and firefighting. Motivated by the desire to understand the
underlying phenomenology and performance bounds associated with imaging targets behind walls, several through-the-wall
imaging experiments were conducted at the Center for Advanced Communications (CAC), Villanova University.
These experiments aimed at supporting resolution, polarization, and localization of indoor targets and objects behind
walls, and provided valuable dual-polarized synthetic aperture data measurements of indoor scenes of different
complexity and population. In this paper, we present
full-polarization imaging results, for a setting of calibrated
reflectors behind a typical exterior grade wall. These imaging results provide polarimetric scene characterization and are
shown to be in good agreement with the ground truth.
