Análisis de deformación de la corteza en el Magdalena Medio con técnicas de interferometría diferencial avanzada y dispersor persistente

Abstract

The present study seeks to implement radar interferometry (InSAR) to characterize the dynamics in the closest layer of the Earth's surface from time series built with multiple SAR images. This technique is known as advanced differential interferometry (ADinSAR). For this purpose we use the Scientific Computing Environment for Interferometry (ISCE). These data were post-processed with persistent scatter (PS) techniques, which seek to extract information in the middle of a scene affected by low coherence (decorrelation) through statistical analyzes in the differential phase of the time series. The chosen algorithm is the Stanford method for persistent disperser StaMPS. The determined study area corresponds to the Middle Magdalena Valley, in the area surrounding Barrancabermeja due to the variety of behaviors that occur on the territory. The main results include urban subsidence, monitoring of oil wells, monitoring of structures and civil works.
