Simulation of Radar Reflection at Man-Made Objects and its Benefits for Persistent Scatterer Interferometry

This paper deals with the analysis of persistent scatterers (PS) in urban areas. We approach the challenge of understanding and exploiting the potential of the new high resolution spaceborne radar data from two sides: a model-driven point of view, i.e., using a forward simulation based on a ray tracer that has been modified for SAR imaging, and a data-driven point of view by exploiting coupled motions of PS in a combined estimation.
