Steps to reproduce

The GPR data were obtained with a GSSI™ (Geophysical Survey Systems, Inc.) SIR-3000 collector with a 200 MHz center frequency antenna, recording up to 12 m depth, coupled to a post-processed GNSS (Global Navigation Satellite System). The arrangement employed was Common Off-set, and frequency and gain filters were used during acquisition. The dielectric constant (10) chosen for the survey represents an average interval velocity of 0.09 m/ns. ). The field records were processed and interpreted using RADAN™ 6.6. and PRISM™ 2.6 softwares. At this stage bandpass filters (350 MHz for low frequencies and 100 MHz for high frequencies), Ormsby, and signal gain filters were applied.
