Identification and analysis of persistent scatterers in series of SAR images

摘要

Disclosed herein is a method for identifying persistent scatterers in digital "Synthetic Aperture Radar" images of an area of Earth's surface each taken at a respective time. The method involves processing the digital Synthetic Aperture Radar images to produce digital generalized differential interferograms. The method further involves analyzing properties of pairs of pixels in the digital generalized differential interferograms to identify individual pixels imaging persistent scatterers.
