Method for identifying persistent scatterers in digital Synthetic Aperture Radar images imaging an area of Earth's surface at different times; the method comprising: • co-registering the digital Synthetic Aperture Radar images; • processing the co-registered digital Synthetic Aperture Radar images to produce digital generalized differential interferograms with respect to a master image, each digital generalized differential interferogram being a differential interferogram between the master image and a respective co-registered digital Synthetic Aperture Radar image, each pixel in the digital generalized differential interferograms being indicative of an interferometric phase; the method being characterized by further comprising: • analyzing properties of pairs of nearby pixels in the digital generalized differential interferograms to identify pixels imaging persistent scatterers, analyzing including - considering pairs of nearby pixels in the digital generalized differential interferograms; - computing, for each considered pair of nearby pixels, corresponding phase-related differential values (δφ a,i) indicative of differences between the interferometric phases of said nearby pixels in the digital generalized differential interferograms; - determining, for each considered pair of nearby pixels, a corresponding temporal-coherence-related value (γ a) on the basis of the corresponding phase-related differential values (δφ a, i), of a corresponding elevation-related differential value (δ h a), and of a corresponding velocity-related differential value (δ v a), said corresponding elevation-related differential value (δ h a) being indicative of a difference between elevations of two corresponding points on the Earth's surface which are imaged by said nearby pixels, said corresponding velocity-related differential value (δ v a) being indicative of a difference between displacement velocities of said two corresponding points on the Earth's surface; and - identifying, among the pixels belonging to the considered pairs of nearby pixels, pixels imaging persistent scatterers on the basis of the determined temporal-coherence-related values (γ a). • co-registering the digital Synthetic Aperture Radar images;
