abstract = "We present 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 a historical of
instability and surface monitoring measurements over sectors of
the mine (pit walls) have been done based on ground based radar.
Two complementary approaches were used: the standard DInSAR
configuration, as an early warning of the slope instability
conditions, and the DInSAR timeseries analysis. In order to
decrease the topographic phase error a high resolution DEM was
generated based on a stereo GeoEye-1 pair. Despite the fact that a
DinSAR contains atmospheric and topographic phase artifacts and
noise, it was possible to detect deformation in some
interferometric pairs, covering pit benches, road ramps and waste
piles. The timeseries 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 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.",
