Parameterisation of layover detector for urban analysis in InSAR data

Building detection is an important topic in InSAR data analysis. Due to the high resolution of modern SAR systems, analysis of urban areas by interferometry is now possible. This opens the floor to new applications, considering not only magnitude images, but also phase images. For this reason, we developed a ramp detector that extracts layover areas of buildings. In this paper, we describe the parameterisation of the layover detector and describe a strategy for specifying the best-suited parameters. Finally, we show results of our parameterisation approach

Interferometric Synthetic Aperture RADAR and Radargrammetry towards the Categorization of Building Changes

The purpose of this work is the investigation of SAR techniques relying on multi image acquisition for fully automatic and rapid change detection analysis at building level. In particular, the benefits and limitations of a complementary use of two specific SAR techniques, InSAR and radargrammetry, in an emergency context are examined in term of quickness, globality and accuracy. The analysis is performed using spaceborne SAR data
