Abstract
When exploiting very high resolution SAR data stacks, the persistent scatterer interferometry algorithm may mistakenly localize scatterers below the ground level. This paper supports this assumption by a case study using the 3D SAR simulator RaySAR. For a specific urban scene, signal reflections between two adjacent buildings lead to the occurrence of ghost persistent scatterers related to reflection level 5-which do not represent the physical shape of the buildings. Eventually, simulation results confirm the strong appearance of the multiple reflected signals on high resolution TerraSAR-X images.Keywords
