The Effect of Air Reflection on Ground Penetrating Radar (GPR) Data


Radar surveys aim to find information about the underground bodies and structures. Some of the radar wave energy leaks out above the surface due to unwanted reflections caused by surrounding features at the survey area like buildings, columns, automobiles, trees, …etc. These unwanted reflections mask the radargram and mislead the analyst in the interpretation phase. In this research two types of air reflections were studied for both types of the GPR antennas, the shielded antenna and the unshielded antenna in order to distinguish between real GPR data from false data caused by air reflections
