A Minimum Curvature Combination Method for the Generation of Multi-Platform DInSAR Deformation Time-Series
Abstract
We present a DInSAR approach for the retrieval of the deformation components through a multi-angle/multi-platform combination strategy. A minimum-curvature combination method has been adopted, based on the exploitation of the line-of-sight (LOS) displacement time-series retrieved by independently processed sequences of SAR data frames. The proposed method can also be seen as a further extension of the MSBAS DInSAR approach but, at variance with it, the algorithm does not require the simultaneous processing of the SAR multi-platform data-sets, and can be applied with no restrictions on the method used for the retrieval of LOS DInSAR time-series, making the field of applicability of it extremely wide. Tests conducted on simulated and real data confirm the validity of the proposed approach. Experiments on real data have been carried out by analyzing three different SAR datasets collected from 2003 to 2010 by the ASAR/ENVISAT (on ascending and descending passes) and the ALOS sensors, respectively.
