Abstract
In order to accurately probe a structure of concrete, a series of probe signals with defined carrier frequencies are generated by a probe signal generator and coupled into the structure by an antenna. The returning echo signals are processed by an echo signal receiver. Processing includes phase and amplitude detection in a multiplier, frequency-specific scaling in a scaling unit, replacement of the measured phases and amplitudes in an interpolation unit, and the generation of time-domain data in a Fourier transformation module. The device is robust against RF noise, accurate and low-power.
