SYNTHETIC APERTURE RADAR INTERFEROMETRY FOR DIGITAL ELEVATION MODEL OF KUWAIT DESERT – ANALYSIS OF ERRORS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Using different combinations of 29 Advanced Synthetic Aperture Radar (ASAR) images, 43 Digital Elevations Models (DEM) were generated adopting SAR Interferometry (InSAR) technique. Due to sand movement in desert terrain, there is a poor phase correlation

Application of the Interferometry Synthetic Aperture Radar (InSAR) in monitoring and evaluating landslides (case study: Ahar-Varzeghan region)

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2021
Introduction Risk management and landslide assessment begin with a comprehensive identification and monitoring of their movements and mapping them, which can be used as a basis for achieving knowledge about their spatial and temporal distribution. The integrated vision of the radar remote sensing images has made them a powerful tool for preparing ...

Multi-temporal Analysis for Differential Interferometry Synthetic Aperture Radar (D-InSAR) and Its Application to Monitoring Land Surface Displcements

open access: yesInternational Journal of Environment and Geosciences, 2017
Land subsidence rate in Semarang has been observed by D-InSAR technique based on ALOS-PALSAR data on ascending orbits, which is processed by GMTSAR and ArcGIS software. Two kind of methods namely single D-InSAR and Multi-Temporal D-InSAR has been done.

Seismic unloading and loading in northern central Chile as observed by differential Synthetic Aperture Radar Interferometry (D-INSAR) and GPS

open access: yesInternational Journal of Remote Sensing, 2003
Using data of two GPS campaigns as well as two ERS-1/2 Single Look Complex (SLC) datasets, we studied the distribution of co-seismic and post-earthquake surface deformation of the major (moment magnitude Mw=8.1) Antofagasta (Chile) event of 30 July 1995. Earthquake-related fault dimensions and inter-seismic surface deformation patterns were achieved by

Determining the Amount of Earthquake Displacement Using Differential Synthetic Aperture Radar Interferometry (D-InSAR) and Satellite Images of Sentinel-1 A: A Case Study of Sarpol-e Zahab City

open access: yesAdvances in Engineering and Intelligence Systems, 2022
One of the effects of an earthquake is the creation of displacement on the land surface. It’s important to determine displacement due to natural disasters such as earthquakes. So, it’s essential to identify height changes occurring on Earth due to these movements.
