This paper reports on the design of a new system for the detection and imaging of steel bars in concrete. It is based on the magnetoresistive effect, whereby the resistance of a material changes due to the presence of a magnetic field. An innovative way of processing and separating the steel characteristics is presented. Here, the combination voltage, frequency and distance parameters generate a unique signature for each metal, profoundly enhancing the analysis.
