Abstract
A least-squares (LS) approach is presented for the retrieval of a temporal deformation sequence from a database of interferometric SAR images. The method uses a database of interferograms, and by solving all the deformations as a unique least squares problem provides a chronologically ordered sequence, describing the development of the deformation pattern in time. The LS approach is illustrated in detail and discussed with respect to the results of its application on a test site.
