Understanding Ambiguities in Backscatterd Orbital Radar Sounding Data from the Martian Polar Layered Deposits Using Finite Difference Time Domain Simulations

The MARSIS orbital radar sounding data has provided our first insights into the internal structure, s-tratigraphy, and basal topography of the polar-layered deposits (PLD) [1]. In order to evaluate the impact of the various geoelectrical and structural characteristics of the deposits on the sounding data obtained by MARSIS and anticipated from SHARAD, we have constructed representative geoelect...

Is the Martian water table hidden from radar view?

[1] Mars may possess a global sub-surface groundwater table as an integral part of its current hydrological system. However, the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) onboard the Mars Express (MEx) spacecraft has yet to make a definitive detection of such a body of liquid water. In this work, we quantify the conditions that would allow a detection of a deep aquife...

Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) after nine years of operation_ A summary

Mars Express, the first European interplanetary mission, carries the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) to search for ice and water in the Martian subsurface. Developed by an Italian–US team, MARSIS transmits low-frequency, wide-band radio pulses penetrating below the surface and reflected by dielectric discontinuities linked to structural or compositional chang...

Martian Surface Radar Reflectivity by Marsis

Introduction: Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) on board Mars Express is a decameter sounder radar, which can work in two different modes : subsurface or ionosphere sounding. The subsurface sounding uses 4 different frequency bands, which are centered to 1.8, 3, 4 and 5 MHz. Each band is 1 MHz wide. [1,2]. In this work, we study the reflectivity of Martian surf...

The SHAllow RADar (SHARAD) Experiment, a subsurface sounding radar for MRO

SHARAD (SHAllow RADar) is a radar for the study of the Martian subsurface provided by the Italian Space Agency (ASI) as a facility instrument on board NASA’s Mars Reconnaissance Orbiter 2005 spacecraft. The scientific objective of SHARAD is the detection of water, either liquid or solid, and the profiling of subsurface ice layers in the first hundreds of meters of the Martian subsurface. Althou...
