Abstract

InSAR’s capabilities have been considerably improved by advanced processing techniques such as Persistent Scatterer Interferometry (PSI) and SAR Tomography (TomoSAR). However, complicated scattering situations (e.g. layover) need to be better resolved in urban areas. This paper presents a new technique for providing the 3D point scatterer location and the resolution cell configuration, based only on the amplitude of SAR images. The implemented method is based on the principle of radargrammetry and uses Bayesian inference. As com-pared to PSI and TomoSAR, the method is insensitive to temporal decorrelation, atmospheric phase screen (APS) and non-linear motion of point scatterers.
