Polarimetric SAR Interferometry (PolInSAR) is an advanced technique (Cloude and Papathanassiou, 1998) of Radar remote sensing that combines the advantages of Polarimetry and Interferometry. Using SAR Polarimetry target characteristics such as its orientation, material constituents (Boerner, 2006, 2004), shape and dielectric properties (Krieger et al.., 2005), permittivity as well as ensemble av...

Abstract Spaceborne interferometric synthetic aperture radar has been proven to be able monitor slow deforming landslides with mm-precision. Continental- and nationwide-scale Sentinel-1 PSI (persistent scatterer interferometry) datasets millions of deformation time series are publicly available, e.g., via the European Ground Motion Service or Germany. This creates possibility for an increased r...

In recent years, space-borne InSAR (interferometric synthetic aperture radar) techniques have shown their capabilities to provide precise measurements of Earth surface displacements for monitoring natural processes. Landslides threaten human lives and structures, especially in urbanized areas, where the density of elements at risk sensitive to ground movements is high. The methodology described...

Coda waves are sensitive to changes in the subsurface because the strong scattering that generates these waves causes coda waves to repeatedly sample a limited region of space. Coda wave interferometry is a technique that exploits this sensitivity to estimate weak changes in the medium from a comparison of the coda waves before and after the perturbation. Here I present the general theory of co...

The subsidence in coal mines induced by surface and subsurface fires leading to roof collapse, infrastructure loss, loss of lives is a prominent concern. In the study, satellite imagery from thermal microwave remote sensing data used deduce effect on Jharia Coalfields, India. Thermal Infrared acquired Landsat-8 (band 10) derive temperature anomaly maps. Persistent Scatterer Interferometry analy...
