First assessment of the permanent scatterer linear displacement model in airborne InSAR time series
This paper presents the very first assessment of the permanent
scatterer (PS) technique for airborne data. A data set
of 14 SAR images at L-band, acquired over the Oberpfaffenhofen
area on the same day with the E-SAR system of the
German Aerospace Center (DLR), is used for the first airborne
time series analysis with PS. The paper shows the importance
of mitigating the residual motion errors through the
use of precise motion compensation strategy before PS analysis.
The target velocity and DEM error results are obtained
by a periodogram-based estimation considering the linear displacement
model. Due to the small number of images in our
data set, the displacement velocity and DEM error results are
presented on a PS basis. Target structures related to selected
reliable PSs are shown and the corresponding periodograms
highlighted
