SummaryThe basic concept of the DGI-SAR „Spaceborne Multiple Aperture and Sequential Patterns Extraction techniques for Accurate Directional Ground and Infrastructure Stability Measurements” project is to develop operational specialized services focused on the Global Monitoring for Environment and Security (GMES) program for natural risk management and in particular for landslides and seismic phenomena in Romania. The project intends to develop innovative monitoring services for critical infrastructure stability, slopes and seismic movements, by applying not only the latest technologies and knowledge in the field, such as spaceborne Synthetic Aperture Radar (SAR), but also original approaches and research that will enhance present space and Earth based techniques. The development of the services relies on the availability of high quality remote sensing data, as well a rich set of in-situ measurements for local geophysical models (velocities,accelerations, etc.) and historical data (archived in-situ and remote sensing data). By integrating Multiple Aperture Interferometry (MAI) techniques with Grouped Frequent Sequential Patterns (GFSP) the project aims at obtaining a high quality model of structural stability and seismic risk. The selected test sites are the Cernavoda Nuclear Power Plant (NPP), Romania and the Saligny versant positioned in the vicinity of NPP. For these areas, a complete and effective modeling of their evolution will consider local deformation patterns, displacement time series patterns and deformation patterns modeled through PS interferometry. Expected end products will consist of: 1) deformation maps - CIMS, SIMS; 2)deformation profiles - CIMS, SIMS; 3) seismic micro – zoning maps - SMMS. The data requested for the completion of the project consist of SpotLight TerraSAR-X images acquired over the area of the Cernavoda Nuclear Power Plant (NPP), Romania. The coordinates of the test area center are approximately 44.330 N and 28.050 E(WGS84) and should remain constant throughout the imaging period. Monostatic interferometric data is needed, acquired on descending right-looking passes,with similar polarizations throughout the data set. Regarding the acquisition geometry, incidence angles with values ranging in the interval 22-25 are required. The funding of the proposal will be entirely supported by University Politehnica of Bucharest in the frame of the research project DGI-SAR „Spaceborne Multiple Aperture and Sequential Patterns Extraction techniques for Accurate Directional Ground and Infrastructure Stability Measurements”, code PN-II-PT-PCCA-2011-3.2-1448, funded by the Romanian Authority for Scientific Research (ANCS) through the National Plan for Research and Development PN-II 2007-2013.
