[ 1 ] - Retrieving Three Dimensional Displacements of InSAR Through Regularized Least Squares Variance Component Estimation

Measuring the 3D displacement fields provide essential information regarding the Earth crust interaction and the mantle rheology. The interferometric synthetic aperture radar (InSAR) has an appropriate capability in revealing the displacements of the Earth’s crust. Although, it measures the real 3D displacements in the line of sight (LOS) direction. The 3D displacement vectors can be retrieved th…

[ 2 ] - تخمین وسعت تخریب ناشی از زلزله با استفاده از تداخل سنجی راداری وتصاویر نوری (مطالعه موردی: زلزله1382 بم)

The estimate of the damage caused by the earthquake and other natural disasters in the first days after the occurrence of these events can provide a quick damages assessment and help to manage the crisis. Several methods are available to investigate the extent of earthquake’s damage. Optical remote sensing, photogrammetric methods (UAVs and LIDARs), radar interferometry (InSAR) and field observat…

[ 3 ] - برآورد پارامترهای هندسی گسل با استفاده از میدان جابجایی سه بعدی حاصل از روش تداخل سنجی راداری (مطالعه موردی: زمین‌لرزه 1396 سرپل ذهاب)

Abstract Earthquakes occur at teh border of teh plates and faults, causing financial and casual damages. Teh study of earthquakes and surface deformation is useful in understanding teh mechanism of earthquakes and managing teh risks and crises of earthquakes. A fault can be specified by its geometric source parameters. In Okada’s definition, these parameters are length, width, depth, strike, dip,…
