Microwave Emission and Scattering models
Survey of Ka backscatter data, models and atmospheric effects
This study is supported by the European Space Agency, and it investigates wave interaction characteristics at Ka-band for a widely varying range of targets linked to potential applications in connection to Ka-band InSAR and polarimetry. More specifically, the objective of the activity is twofold: (1) to establish a library of well calibrated Ka-band backscatter coefficients; (2) to establish accurate models of Ka-band scattering and propagation for a variety of natural (both land and sea) and manmade targets. The output of the study will be used to support instrument parametric analyses and for establishing system requirements such as SNR, NESZ and imaging ambiguities. The criticality of atmospheric effects is studied as well. Datasets at Ka-band (groundbased and airborne) are used as a basis and supported by available forward EM models for the variety of natural targets (including its related variability).  
Forests and grass
The electromagnetic model developed by our research group is able to simulate both the emission and the scattering of soil covered by different kinds of vegetation. In the recent years, the model was tested and refined using airborne and ground based measurements collected over various forest sites, in France, Germany, Finland, Italy, Argentina. Results are being used in the development of algorithms for the explitation of satellite data over forests. New tests are in progress using active and passive microwave data collected over Australian forests. Further tests are in progress, in order to test the model ability to reproduce the yearly cycle of emissivity and backscattering coefficient. Satellite data collected over extended grass areas of China are used to this purpose.
Wetlands
The emission and scattering model was also adapted to exploit the potential of radar to identify and monitor wetland properties, such as marsh type, submerging due to variations of water level, regrowth after burns. The technique was successfully tested using ASAR data collected over marshes of Parana river.
Agricultural fields
The objective of this project is to allow physical understanding of the scattering  processes at L- and C-band to develop retrieval algorithms for soil and vegetation parameters. The microwave scattering model developed at Tor Vergata has been refined to check the validity of some approximations (e.g. by subdividing a single leaf into several small discs, and considering an “equivalent” stem). Advanced theories have been considered and the agreement between simulations and available experimental data has been improved. 
Bi-Static Microwave Measurements for Earth Observation
This project aimed to study the feasibility of remotely sensing the earth (land surface) using a spaceborne bistatic system at microwave bands. For this purpose, electromagnetic models have been implemented in order to understand the sensitivity of bistatic measurements to geophysical parameters, compatibly with the technological feasibility of the measurements themselves
