A MULTI-STEP DE-NOISING METHOD FOR INTERFEROGRAM IN PS-INSAR

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Abstract. In order to reduce the influences of the noises in Synthetic Aperture Radar (SAR) image on accurate extraction of permanent scattered (PS) points in PS-InSAR technology, a multi-step de-noising approach considering the characteristics of the noises is proposed in this study.

PS-InSAR derived deformation study in the Kachchh, Western India

Applied Computing and Geosciences, 2020
The accumulation of crustal strain towards the western part of India, especially in the Kachchh Rift basin, is making one of the most seismically active parts of the Indian plate. Several strong to major earthquakes, including the recent 2001 (M7.7) Bhuj earthquake, were triggered in the Kachchh rift basin during the last two centuries.

A First Approach for Displacement Analysis in Lisbon Downtown Using PS-InSAR

Procedia Technology, 2014
AbstractLisbon Downtown presents unique geomorphologic properties which makes it an area prone to terrain instability. Serious accidents have occurred there, namely, during the 1755 earthquake and a flooding event at the extension of a subway line, demanding a frequent monitorization for safety reasons and expense minimization. In this study, Permanent
