Abstract

In this work, a prototype of microwave imaging system for through-the-wall monitoring is presented. The system can operate remotely, as well as by using antennas directly in contact with the wall. For the remote modality, ad-hoc wide-band antennas have been designed and integrated into an efficient measurement system, able to acquire the scattered-field data. Such measurements are processed by a novel hybrid inversion procedure able to create an image of the inspected scenario. For the proximity modality, a Bessel beam launcher is specifically designed, realized and tested to provide a focused near-field with enhanced penetration capabilities. Preliminary results are provided for assessing the capabilities of the system.
