abstract = "This work presents an investigation to determine ground
deformation based on an integration of DInSAR Time-Series (DTS)
and Persistent Scatterer Interferometry (PSI) techniques aiming at
detecting high rates of linear and non-linear ground movement. The
combined techniques were applied in an open pit iron mine located
in Caraj{\'a}s Mineral Province (Brazilian Amazon region), using
a set of 33 TerraSAR-X-1 images acquired from March 2012 to April
2013 when, due to a different deformation behavior during the dry
and wet seasons in the Amazon region, a non-linear deformation was
detected. The DTS analysis was performed on a stack of multi-look
unwrapped interferograms using an extension of the SVD (Singular
Value Decomposition), where a set of additional weighted
constraints on the acceleration of the displacement was
incorporated to control the smoothness of the time-series
solutions, whose objective was to correct the atmospheric phase
artifacts. The height errors and the deformation history provided
by the DTS technique were used as previous information to perform
the PSI analysis. This procedure improved the capability of the
PSI technique to detect non-linear movement as well as to increase
the numbers of point density of the final results. The results of
the combined techniques are presented and compared with total
station/prisms and ground-based radar (GBR) measurements.",
