Description:
In this work, the effects of magnetic inclusions in a Mars-like soil are considered with reference to
the electromagnetic propagation features of ground-penetrating radars (GPRs). Low-frequency and
time-domain techniques, using L-C-R meters and TDR instruments, respectively, are implemented
in laboratory experimental set-ups in order to evaluate complex permittivity and permeability and
wave velocity for different scenarios of a dielectric background medium (silica) with magnetic
inclusions (magnetite). Attenuation and maximum detection ranges have also been evaluated by taking
into account a realistic GPR environment, which includes the transmitting/receiving antenna
performance and the complex structure of the subsurface. The analysis and the interpretation of
these results shed new light on the significant influence of magnetic inclusions on the performance
of Martian orbiting and rover-driven GPRs.
