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.
