ABSTRACT

Materials-penetrating ultrawideband (UWB) radar (MPR) systems remotely sense objects within multilayered media such as soil, rock, concrete, wood, air, and biological tissue. This radar category includes ground-penetrating, through-wall, mine-detecting, and medical UWB imaging systems. These systems present special problems because of the varying velocity of the propagation signal, attenuation, and re‘ections from changes in the electrical properties of the media.
