چکیده

In the last two decades, scientists have developed a powerful technique to measure the millimeterscale of the Earth ̳s surface deformation by comparing complex synthetic aperture radar (SAR) data that were acquired a few days or a few years apart. This technique is known as interferometric synthetic aperture radar (InSAR). The paper is focused on simulation of volume deformation of coastal érosion from interferometry synthetic aperture radar (InSAR). In doing so, conventional InSAR procedures are implemented to three repeat passes of ENVISAT ASAR data. Further, threedimensional sorting reliabilities algorithm (3D-SRA) is implemented with phase unwrapping technique. Consequently, the 3D-SRA is used to eliminate the phase decorrelation impact from the interferograms. The study shows the performance of InSAR method using the 3D-SRA is better than InSAR procedure. The rate of volume of the coastal erosion is 3000 m 3 /year. In conclusion, integration of the 3D-SRA with phase unwrapping produce accurate 3-D coastline deformation.
