Abstract :
A ground monitoring system that exploits electromagnetic field properties of accounting of both physical and geometrical features of the surrounding medium is proposed. The system is based on TDR tests, assisted by a control and processing unit, and aims at detecting starting cavities underground in the soil. The digital signal processing approach deployed for waveform analysis, which plays a fundamental role in detecting and characterizing underground anomalies, is described.
