QUInSAR: Temporal Parameter and Ambiguity Estimation Using Recursive Least-Squares: A Methodology for Persistent Scatterer Interferometry

Parameter and ambiguity estimation in the temporal domain, for arcs of differential phase observations between two persistent scatterers (PS), is a critical part in Persistent Scatterer Interferometry (PSI). Deformation models, used as constraint in the parameter estimation, often do not capture the full extent of the deformation behaviour. This...
