3d geolocation capability of medium resolution SAR sensors

Persistent Scatterer Interferometry (PSI) [1,2] can estimate height and Line of Sight (LOS) deformation of Persistent Scatterers (PS) relative to a reference point. But the main limitation comes in understanding where these reflections stem from, what is exactly deforming, and with respect to what [3,4,5]. One of the vital parameters in identifying and associating radar scatterers to real world objects comes from scatterer’s 3D geolocation and its quality.
