Abstract

In monostatic ground penetrating radar (GPR) the interfaces profile can be estimated from echoes amplitude and time of delay (TOD) using a layer stripping inversion algorithm. The authors' aim is to establish a reliable processing sequence for layer stripping inversion by estimating echoes TOD that keeps into account the layers lateral continuity, and by tracking the corresponding interfaces. The authors propose first an algorithm for multitarget tracking and then they describe the application of detection/tracking to Ins pulse monostatic GPR. The system is used to estimate layer thicknesses of asphalt and concrete in pavement profiling. Detection/tracking shows a better recognition capability of the lateral continuity in near surface interfaces with respect to algorithms that employ only local detection of echoes.
