摘要

Method for monitoring displacement of Terrain and man-made Elements using Synthetic Aperture Radar Data (gbsar Terrestrial).A method for monitoring displacement of Terrain and man-made elements that includes preprocess Joint Complex Sar Images acquired in the first Campaign, and in a later campaign by an Instrument gbsar incoherent average Sar image to obtain a P For each Campaign, selecting, in each of the incoherent average Sar Images.Pixels that are representative of goals respectively in each of these data sets of Sar Images, and the goals of Artificial Corner reflectors, if has deployed in the area of interest.And Natural reflectors in the area of interest; a Global correlation of images about the pixels selected to obtain a set of pairs of standard deviations expressed in pixels and select a Plurality of pairs of deviations with overall quality score; Estimating effects of repositioning gbsar Mask which comprises obtaining a pixel area Stable corRespondents to stable areas in the area of interest, calculating a subset of Global deviations within the Mask, Estimating a Transformation of co Registration based on the subset of standard deviations,And producing a set of parameters of coregistration which models the effects of repositioning gbsar pairs; estimate of displacement for each campaign by the effects of repositioning gbsar coregistration parameters modeled by the set of pairs of standard deviations,Thus, a Plurality of pairs of deviations of displacements expressed in pixels, Making the deviations of displacement expressed in pixels in displacements expressed in a Unit DisplacementAnd getting a set of pairs of displacement Estimates in a defined Space Object through geocoding involves a Transformation Image object.
