Space‐borne radar interferometry techniques for the generation of deformation time series: An advanced tool for Earth's surface displacement analysis

Abstract

This work is focused on advanced differential SAR interferometry (DInSAR) techniques for the generation of deformation time series from sequences of SAR images. We first present the basic rationale of these techniques providing some details of the most well known algorithms. Subsequently, through the analysis of selected case studies focused on the available C‐band SAR data archives, we show the relevance of the retrieved spatially dense deformation time series for the comprehension of several geophysical phenomena. We finally introduce, again via a real case study, the advances brought in by the new generation X‐band space‐borne SAR sensors, highlighting new investigation possibilities for fast varying deformation phenomena.
