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.

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...

The detection of active rock glacier and the quantification of the observed surface movement as well as its temporal change using the D-InSAR method are presented. An average deformation rate of -7.7 mm/35 days in the radar lineof-sight, in the summer of 1992, was estimated. Whereas, the corresponding geodetic measurement, vertical component of 3D flow velocity, was about –8.0 mm/35 days. Addit...

In this paper the selected interferometric studies of subsidence caused by underground mining are discussed. Despite the common limitations the traditional single-polarization InSAR technique is already proved its high potential in this application. Today, the determination of the areas of affected by terrain deformation risks becomes one of the most promising applications for operational use o...

The problem of phase unwrapping in two dimensions has been studied extensively in the past two decades, but the three-dimensional (3D) problem has so far received relatively little attention. We develop here a theoretical framework for 3D phase unwrapping and also describe two algorithms for implementation, both of which can be applied to synthetic aperture radar interferometry (InSAR) time ser...
