The Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) currently operating on Mars needs a fine ionospheric correction in order to deliver products useful for geological investigations. Ionosphere influence can be assessed using a new approach based on the finite-difference time-domain (FDTD) method. The proposed work aims to underline the errors introduced by a not perfect knowledge of the ionospheric electron density profile on the chirp signal range compression. Such effect has a great impact on the data inversion process that aims to estimate the permittivity of the subsurface detected interfaces.

Abstract
The Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) currently operating on Mars needs a fine ionospheric correction in order to deliver products useful for geological investigations. Ionosphere influence can be assessed using a new approach based on the finite-difference time-domain (FDTD) method. The proposed work aims to underline the errors introduced by a not perfect knowledge of the ionospheric electron density profile on the chirp signal range compression. Such effect has a great impact on the data inversion process that aims to estimate the permittivity of the subsurface detected interfaces.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
