抄録(英) | High-frequency, ultra-wideband penetrating radar has the potential of being used as a non-invasive inspection technique for buildings, which is useful to support refurbishment works. We conducted numerical and laboratory experiments using a proximal, stepped-frequency continuous-wave (SFCW) radar system operating in zero-offset mode, spanning the 3-8GHz frequency range. The reconstruction of the material electrical properties is achieved by resorting to full-waveform inverse modeling. Numerical experiments showed it is possible to retrieve the physical properties of the material and to individuate fractures about 1mm thick. Laboratory experiments were conducted on non-reinforced concrete and plaster slabs lying in different configurations. |
