Abstract
A wall detector () for detecting an object () embedded in a substrate () includes a detection antenna () for introducing broadband, high-frequency alternating electric fields () of a measurement frequency (f) in the substrate (); a measurement system () connected to the detection antenna () for measuring the delayed interaction of the alternating fields () with the object (), a calculation device () for detecting the object () based on the measurement signal and for determining the associated depth information, and a permittivity measurement device () with at least one auxiliary potential plate () for measuring the permittivity measurement signal of the substrate at a permittivity measurement frequency (f) that is a lower than the measurement frequency; and an associated measurement method.
