abstract = "This work presents an investigation of surface deformation using
Differential SAR Interferometry (DInSAR) time-series carried out
in an active open pit iron mine, the N5W, located in the
Caraj{\'a}s Mineral Province (Brazilian Amazon region), using 33
TerraSAR-X (TSX-1) scenes. This mine has presented surface of
deformation and monitoring measurements over sectors of the mine
(pit walls) have been done based on ground based radar. In order
to decrease the topographic phase error a high resolution DEM was
generated based on a stereo GeoEye-1 pair. The time-series
analysis was performed using the 31 interferometric pairs, which
were selected based on the highest mean coherence of a stack of
107 interferograms, presenting less phase unwrapping errors. The
time-series deformation was retrieved by the Least-Squares (LS)
solution using an extension of the Singular Value Decomposition
(SVD), with a set of additional weighted constrain on the
acceleration deformation. The atmospheric phase artifacts were
filtered out in the spacetime domain and the DEM height errors
were estimated based on the normal baseline diversity. The DInSAR
time-series investigation showed good results for monitoring
surface displacement in the N5W mine located in a tropical
rainforest environment, providing very useful information about
the ground movement for alarm, planning and risk assessment.",
