Satellite radar interferometry (InSAR) can be applied to study vertically integrated atmospheric refractivity variations with a spatial resolution of 20 m and an accuracy of 2 mm, irrespective of cloud cover or solar illumination. The data are derived from the diierence between the radar signal delay variations within the imaged area during two acquisitions with a temporal separation of one or ...

The improved ground resolution of state-of-the-art synthetic aperture radar (SAR) sensors suggests utilizing this technique for analysis of urban areas. However, building reconstruction from SAR or InSAR data suffers from consequences of the inherent oblique scene illumination, such as foreshortening, layover, occlusion by radar shadow and multipath signal propagation. Especially in built-up ar...

In 1995 Atlantis became involved in value added services using repeat-pass InSAR data. The joint in-house development of the EarthView commercial off-the-shelf (COTS) software and the evolution of InSAR technology for value added services has been a key component to the success and growth of the services. This evolution included the development of robust innovative tools, methods for prediction...

Interferometric Synthetic Aperture Radar (InSAR) and Differential Interferometric Synthetic Aperture Radar (DInSAR) have shown numerous applications for subsidence monitoring. In the past 10 years, the Persistent Scatterer InSAR (PSI) and Small BAseline Subset (SBAS) approaches were developed to overcome the problem of decorrelation and atmospheric effects, which are common in interferograms. H...

The aim of this study was to investigate the relationship between surface subsidence and groundwater changes. To investigate this relationship, we first analyzed surface subsidence. This paper presents the results of a case study of surface subsidence in Beijing from 1 August 2007 to 29 September 2010. The Multi-temporal Interferometric Synthetic Aperture Radar (multi-temporal InSAR) technique,...

State-of-the-art space-borne high resolution SAR sensors such as TerraSAR-X, SAR-Lupe or Cosmo-SkyMed provide SAR images of 1-3m spatial resolution or even below in special spotlight modes. Due to this high resolution, one major issue of these missions is the development of methods to automatically derive detailed cartographic information from their recorded data by focusing on rural as well as...

Interferometric Synthetic Aperture Radar (InSAR) has become the primary remote sensing detection method for monitoring significant surface subsidence and deformation caused by underground coal mining. Time Series InSAR been intensively researched in mining-caused its ability to provide time series, with Small Baseline Subset (SBAS-InSAR) Permanent Scatter (PS-InSAR) being two classical methods....

Emission of the CO2 from the Indonesian forest is mainly composed of the deforestation, forest degradation, and the peat land subsidence. Peat land subsidence of Indonesian islands represented by the Central Kalimantan is induced by the global warming and the resultant chemical processes at the peat land emit the CO2 to the air. The measurement of a relationship between the subsidence speed and...

The method of stochastic simulation is proposed to model the atmospheric effect on InSAR measurements based on sample data. Test results show that 37.44% reduction in the standard devisation of the atmospheric errors can be achieved with the method of stochastic simulation, compared to 25.69% with the method of Kriging interpolator. The relative improvement of the former over the latter amounts...
