Performance of ground penetrating radar employing buffer-layered antennas for groundwater detection based on frequency scaling model / F. Farihas and I. Pasya

Groundwater detection using classical
electromagnetic (EM) wave ground penetrating radar (GPR),
which utilizes single-input single-output (SISO) antenna
configuration in open-air condition, results in poor signal
propagation through soil. This paper proposes groundwater
detection using enhanced GPR system utilizing buffer-layered
antennas, where an additional medium is placed between the
antenna and the ground, acting as a matching layer. The
performance of the proposed scheme is investigated using
frequency-domain time-domain (FDTD) based numerical
simulation. Typically, numerical GPR simulation using real
measurement parameters requires large number of meshing and
therefore takes longer time to perform and is run on computers
with high specification. In this paper, comparison between
simulations using real scale and frequency scale model is also
presented. Simulation result indicates improvement in wave
propagation inside homogeneous soil using buffer-layered
antenna, which can be observed in both real scale and frequency
scale simulations.
