|Title||Digital Surface Models generation by high resolution dual pol TerraSAR-X imagery: analysis of polarimetric SAR tomography potentialities over urban areas|
|Investigator||Porfiri, Martina - University of Rome "La Sapienza", DICEA|
|Summary||The main topic of this project is about the analysis of polarimetric SAR tomography (PolTomSAR) potentialities for DSMs generation by high resolution dual polarisation TerraSAR-X imagery. The objective is to generate accurate and complete DSMs on urban areas exploiting the capability of this technique to retrieve height information and reconstruct volumetric environments. |
The processing will be performed by using the software listed here after and extending their potentialities with custom plugin:
TomSAR is a tridimensional SAR imaging mode based on the use of a stack of images performed in interferometric configuration, and combined in order to form a synthetic aperture in the elevation direction. Performing SAR tomography with a polarimetric diversity, the power of separation between different components of complex volumic media could be improved. In this way it is possible to reconstruct the 3D characterization of volumetric environments and to detect specific structures. This approach requires an interferometric and a tomographic processing. The former will be performed at GGD laboratory using SARscape® software; the latter will be performed in IETR laboratories. In this TerraSAR-X proposal HS and SM dual-pol data over different urban areas are required in order to evaluate the potentialities of this technique using data at different resolutions.
Being our project goal mainly methodological, we are not interested in a precise study area. For this reason we would like to require data acquired over different areas like Spain, Germany and Japan. In order to achieve this project, following data are required:
The project will be carried out in the context of a joined doctoral thesis between the University of Rome “La Sapienza” and the University of Rennes 1. Therefore, the funding will be provided in different parts by both Universities, thanks to the PhD fellowship and the relative research funds. Moreover, a research fellowship has been won in the context of the ‘Bando VINCI’, a competitive program aimed to promote the exchange of methodologies and experiences between Italy and France.
