The aim of this paper is deformation monitoring over urban areas using Persistent Scatterer Interferometry (PSI) and Very High Resolution (VHR) X-band SAR imagery. Since the launch of TerraSAR-X and the first COSMO-SkyMed satellite (both were launched in June 2007), the VHR X-band data has grown in importance as source of PSI. This is due to the remarkable increase of the data acquisition capability (for instance, the COSMO-SkyMed constellation consists of three SAR satellites in mid 2010), the progressive loss of key sources of SAR images, as ASAR-Envisat and ERS-2, and the promising technical characteristics of the Xband. This paper illustrates some of the main results of the PSI analysis derived from VHR X-band data. The analysis was carried out over a stack of SAR images captured by the TerraSAR-X sensor and covering the metropolitan area of Barcelona (Spain). This work is the first experience of the authors with PSI analysis of the X-band, which is based on a rich set of 28 StripMap images. These images were processed and analysed using the PSI in-house experimental software chain of the Institute of Geomatics. A description of the Barcelona dataset and the main outcomes of the PSI analysis is given. These outcomes reflect a preliminary assessment of the improvement which can be achieved by VHR X-band PSI, mainly in terms of deformation monitoring capability.

Abstract
The aim of this paper is deformation monitoring over urban areas using Persistent Scatterer Interferometry (PSI) and Very High Resolution (VHR) X-band SAR imagery. Since the launch of TerraSAR-X and the first COSMO-SkyMed satellite (both were launched in June 2007), the VHR X-band data has grown in importance as source of PSI. This is due to the remarkable increase of the data acquisition capability (for instance, the COSMO-SkyMed constellation consists of three SAR satellites in mid 2010), the progressive loss of key sources of SAR images, as ASAR-Envisat and ERS-2, and the promising technical characteristics of the Xband. This paper illustrates some of the main results of the PSI analysis derived from VHR X-band data. The analysis was carried out over a stack of SAR images captured by the TerraSAR-X sensor and covering the metropolitan area of Barcelona (Spain). This work is the first experience of the authors with PSI analysis of the X-band, which is based on a rich set of 28 StripMap images. These images were processed and analysed using the PSI in-house experimental software chain of the Institute of Geomatics. A description of the Barcelona dataset and the main outcomes of the PSI analysis is given. These outcomes reflect a preliminary assessment of the improvement which can be achieved by VHR X-band PSI, mainly in terms of deformation monitoring capability.File | Dimensione | Formato | |
