COMPARISON OF THE IMPULSE AND M-SEQUENCE UWB RADAR SYSTEMS FOR THE ESTIMATION OF THE WALL THICKNESS [PDF]

open access: yesActa Electrotechnica et Informatica, 2019
In our laboratory, we developed a simple estimation of the wall thickness by the UWB (Ultra Wide-Band) radar system. The described technique measures the wall thickness in the two steps. The first step is a measurement of the wall relative permittivity.
