The differential interferometric synthetic aperture radar (DInSAR) method is based on phase variation between the complex value of pixels timely separated scenes in SAR pairs. This has five components: surface topography, curvature planet’s surface, terrain displacement, volume scatterers, and atmospheric propagation effects. displacement main product DInSAR method, while last two effects are u...

Differential interferometry of synthetic aperture radar (DInSAR) can be used to generate high-precision surface displacement maps in continuous permafrost environments, capturing isotropic subsidence and uplift associated with the seasonal freeze thaw cycle. We generated using DInSAR ultrafine-beam Radarsat-2 data for summers 2013, 2015, 2019 at Cape Bounty, Melville Island, examined them combi...

As complementary to Synthetic Aperture Radar (SAR) Differential Interferometry (DInSAR), SAR Offset Tracking (OT) is an efficient tool for large ground deformation monitoring in situations when DInSAR cannot work. However, images are affected by speckle noise and some strong point-like scatters which can cause what known as Patch Like (PL), a kind of errors that be seen homogeneous patches almo...

Natural disasters and human activities are now causing an increase in land subsidence, or surface displacement. The effects of subsidence cause landslides construction cracking. PSInSAR (Persistent Scatter Interferometry) was identified to estimate displacement from a time series Synthetic Aperture Radar (SAR) images. This technique is subset the DInSAR (Differential Interferometric Radar) meth...

China is the world’s largest coal-producing country and mining-related land subsidence happens almost in every coal mining area. In north-west China, land subsidence in coal mining areas is mainly caused by underground mining activities and uncontrolled burnings of subsurface coal seam. As Hoffmann (2004) reported, burning coal-seams can result in extensive subsidence of several meters and typi...

Due to the capability to provide direct physical measurements, interferometry is among the remote sensing techniques that have most pushed the applications of SAR to a wide range of scientific areas and have provided direct returns for our society in terms of improved security. Repeat pass DInSAR and, more specifically, its evolution to Persistent Scatterers Interferometry (PSI), which allows t...

Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR™) é uma técnica de sensoriamento remoto que usa como base a Differential InSAR (DInSAR), porém, emprega série interferogramas diferenciais advindas pilha imagens Single Look Complex - (SLC-SAR) devidamente corregistradas e adquiridas em um intervalo tempo sobre mesma área para, tal modo, selecionar pixels apresentam índice d...
