Abstract
Persistent Scatterer (PS) analysis of urban areas using high resolution SAR data is an important and by this time mature technique to estimate deformation and 3D information. Due to the high resolution a large number of PS is available per building. Beyond that the scatterers residing on one building often form patterns, which hold information about the relations between the PS. We present an approach to find horizontal rows of PS, utilizing some prior knowledge about the building under investigation. The found rows are then employed to facilitate the estimation of height information.
