Abstract
InSAR time-series analyses use multiple SAR images acquired on different dates to map time evolution of small and quasi-steady ground displacements. StaMPS (Stanford Method for Persistent Scatterers) is a software package for an InSAR persistent scatterer (PS) analysis, which is one category of the InSAR time-series analyses. The package is freely available for non-commercial applications. This report explains the main features of StaMPS and its basic algorithm. The algorithm of StaMPS has been developed to work even in terrains devoid of man-made structures and/or undergoing non-steady deformation. StaMPS uses the spatial correlation of the phases in selecting PS pixels, which enables identification of more PS pixels than conventional algorithms can identify. This further permits successful phase unwrapping without calling for any phase history model, which is required by other algorithms.
