Abstract :
We present a new approach for the evaluation of the Earth surface deformation evolution based on the combination of several differential interferograms spanning a time interval of interest. In particular we present a method that extends the least squares combination technique presented by S. Usai et al. (2000) by applying the singular value decomposition (SVD) method. Experiments carried out on ERS data validate the proposed approach
