Method for monitoring displacement of terrain and man elements using ground radar data synthetic aperture (gbsar) created.

摘要

Method for monitoring ground displacements and elements man using radar data terrestrial synthetic aperture (GBSAR) created. # A method of monitoring ground displacements and elements man comprising preprocessing sets of complex SAR images acquired created in a first campaign, and in a subsequent campaign by a GBSAR instrument to obtain an average SAR image inconsistent for each campaign; #seleccionar, in each of the average SAR images incoherent, pixels that are representative of targets respectively in each of said datasets SAR images, selected the aforementioned objectives artificial corner reflectors, if has deployed in the area of ​​interest, and natural reflectors in the area of ​​interest; #realizar a global correlation of images on the pixels selected to obtain a set of pairs of global deviations in pixels and selection ar a plurality of pairs of global deviations quality score; #estimar effects repositioning GBSAR comprising obtaining a mask pixel corresponding to stable stable area areas the area of ​​interest, calculating a subset of global deviations entering the mask, estimating a transformation coregistration based on the subset of global deviations, and producing a set of parameters that models the effects coregistration repositioning GBSAR; #estimar pairs of offsets for each campaign by removing the effects of repositioning GBSAR modeled by parameters of coregistration set of pairs of global deviations, thereby obtaining a plurality of pairs of displacement deviations expressed in pixels, making displacement deviations in displacement in pixels expressed in a displacement unit, and obtaining a set of pairs of estimated displacements in a space defined by geocoding object implies a transformation object image.
