Very High Resolution Parametric and Non- Parametric Sartomography Methods for Monitoring Urban Areas Structures
Synthetic Aperture Radar (SAR) is the only way to evaluate deformation of the Earth’s surface from space on the order of centimeters and millimeters due to its coherent nature and short wavelengths. Hence, by this means the long term risk monitoring and security are performed as precisely as possible. Traditional SAR imaging delivers a projection of the 3-D object to the two dimensional (2-D) a...
متن کاملCombining L- and X-Band SAR Interferometry to Assess Ground Displacements in Heterogeneous Coastal Environments: The Po River Delta and Venice Lagoon, Italy
From leveling to SAR-based interferometry, the monitoring of land subsidence in coastal transitional environments significantly improved. However, the simultaneous assessment of the ground movements in these peculiar environments is still challenging. This is due to the presence of relatively small built-up zones and infrastructures, e.g., coastal infrastructures, bridges, and river embankments...
متن کاملCarsten Jürgens (Ed.): Remote Sensing - New Challenges of High Resolution, Bochum 2008
The new spaceborne very high resolution (VHR) SAR sensors onboard the TerraSAR-X and COSMO-SkyMED satellites have a spatial resolution of up to 1 meter. In VHR SAR data, features from individual urban structures, like buildings, can be identified in their characteristic settings in urban settlement patterns. In the context of situation assessment as initial reaction to man made or natural crisi...
متن کاملInterferometric Multi-chromatic Analysis of High Resolution X-band Data
The Multi-Chromatic Analysis (MCA) consists of performing sub-bands splitting in range frequency domain, thus generating chromatic views of lower range resolution, centered at different carrier frequencies. Multi-chromatic interferograms can be then generated by coupling chromatic views coming from an interferometric pair of SAR images. The interferometric phase of spectrally-stable scatterers ...
متن کاملAdvanced Methods For Building Information Extraction From Very High Resolution SAR Data To Support Emergency Response
Rapid damage assessment after natural disasters (e.g. earthquakes, floods) and violent conflicts (e.g. war-related destruction) is crucial for initiating effective emergency response actions. Remote sensing satellites equipped with multispectral and Synthetic Aperture Radar (SAR) imaging sensors can provide vital information due to their ability to map affected areas of interest with high geome...
