Test and data processing of a stepped-frequency GPR array

Abstract

Recording of ground-penetrating radar data is very time consuming compared to other geophysical prospection methods like magnetics. The spatial resolution of the technique is so high, that a very dense survey grid is necessary to properly record the anomalies and to prevent aliasing. Additionally the antennas need direct contact with the ground, which reduces the maximum possible survey speed in the field. In magnetometry it has become standard to use several sensors to speed up field recording, (...)
