A new algorithm for surface deformation monitoring based on small baseline differential SAR interferograms
TLDR
Results obtained on the data acquired from 1992 to 2000 by the European Remote Sensing satellites and relative to the Campi Flegrei caldera and to the city of Naples, Italy, that demonstrate the capability of the proposed approach to follow the dynamics of the detected deformations.Abstract:
We present a new differential synthetic aperture radar (SAR) interferometry algorithm for monitoring the temporal evolution of surface deformations. The presented technique is based on an appropriate combination of differential interferograms produced by data pairs characterized by a small orbital separation (baseline) in order to limit the spatial decorrelation phenomena. The application of the singular value decomposition method allows us to easily "link" independent SAR acquisition datasets, separated by large baselines, thus increasing the observation temporal sampling rate. The availability of both spatial and temporal information in the processed data is used to identify and filter out atmospheric phase artifacts. We present results obtained on the data acquired from 1992 to 2000 by the European Remote Sensing satellites and relative to the Campi Flegrei caldera and to the city of Naples, Italy, that demonstrate the capability of the proposed approach to follow the dynamics of the detected deformations.read more

A multi-temporal InSAR method incorporating both persistent scatterer and small baseline approaches
Andrew Hooper,Andrew Hooper +1 more
TL;DR: A new method is presented that combines both approaches, to extract the deformation signal at more points and with higher overall signal-to-noise ratio than can either approach alone.

A small-baseline approach for investigating deformations on full-resolution differential SAR interferograms
TL;DR: The algorithm extends the capability of the small-baseline subset (SBAS) technique that relies on small- Baseline DIFSAR interferograms only and is mainly focused on investigating large-scale deformations with spatial resolutions of about 100/spl times/100 m.
