Radar processing and simulation, surface and shallow subsurface composition of Mars


Buried CO2 Ice traces in South Polar Layered Deposits of Mars detected by SHARAD using fractal modelling of the suveyed geometry. From our result, there is possibly CO2 ice buried in the first 8 m below the sursface in the area overlapping the Hesperian and Amazonian polar units (presented at the 2014 AGU Meeting).


The research topic for which I am interested in is the mathematical modelling of different aspect of electromagnetic fields paying particular attention to the radar. The main objective of my work includes development of simulation models for analyzing the performance of the radar, the analysis and development of mathematical models to understand the composition of the materials in a scenario. In general my research is founded on developing new mathematical methods to model scenario as much as can be near the reality.

Currently my projects in this area include the analysis of data from the instrument SHARAD, Shallow Radar, the radar mounted on board the Italian mission, MRO (Mars Reconnaissance Orbiter) NASA, with particular reference to implementation of algorithms for discernment of the scientific data. These studies have recently led to a modeling of the Martian surface in some areas of considerable interest to physical and abiotic characteristics. I also carried out a research project on the calibration of radar data in a way that is transparent to the scientist collecting data and processing, in this way the scientist will be able to extract geophysical parameters from backscattering measurements using multi-teporal observations over large areas.

I recently developed a collaborative filter to decrease the speckle in SAR images:
