Аннотация: To detect small movements of the Earth surface (with a velocity of less than several centimeters per year) with use of SAR-interferometry methods it is necessary to find a number of surface areas remaining coherent in radar images over a long period. These areas and corresponding image points are called persistent scatterers. Two methods of persistent scatterers detection are considered in the paper. The methods are compared by the number of detected points and their average time coherence. The algorithms considered are illustrated with an example of processing of a set containing 35 radar images. © 2015, Institution of Russian Academy of Sciences. All rights reserved.
