How to accurately determine the mechanical parameters of rockfill is one of the key issues of concrete-face rockfill dams. Parameter back-analysis using internal or external monitoring data has been proven to be an efficient way to solve this problem. However, traditional internal or external monitoring methods have limitations in efficiency and long-term monitoring. In this paper, the displace...

InSAR (space-borne Synthetic Aperture Radar Interferometry) data has revealed to be useful for surveying landslides and permafrost creeping features (e.g. rock glaciers) as it permits a time-lapse quantification of topography changes at mm to cm resolution over alpine areas where dense vegetation is no longer present. The capability of InSAR for detecting both the location of moving zones and t...

In this paper, an original approach for analyzing Interferometric Synthetic Aperture Radar (InSAR) time series is presented and applied to the monitoring of creep along a major active fault. InSAR data are computed from satellite acquisitions and allow ground deformations occurring between different dates to be measured with high precision over large areas. However, measurement precision remain...

Synthetic Aperture RADAR Interferometry (InSAR) provides a unique tool for the quantitative measurement of the Earth’s surface deformations induced by a variety of natural (such as volcanic eruptions, landslides and earthquakes) and anthropogenic (e.g., ground-water extraction in highly-urbanized areas, deterioration of buildings and public facilities) processes. In this framework, use of InSAR...

Atmospheric water vapour effects represent a major limitation of repeat-pass Interferometric SAR (InSAR) techniques including InSAR time series approaches (e.g. permanent scatterers (PS) and small baseline subset (SBAS)). In this paper, it is demonstrated that atmospheric water vapour effects greater than 4 cm can be observed even in desert regions (e.g. Southern California) and the use of MERI...

BACKGROUND REDD+ implementation requires establishment of a system for measuring, reporting and verification (MRV) of forest carbon changes. A challenge for MRV is the lack of satellite based methods that can track not only deforestation, but also degradation and forest growth, as well as a lack of historical data that can serve as a basis for a reference emission level. Working in a miombo woo...

During the last two decades synthetic aperture radar (SAR) and interferometric synthetic aperture radar (InSAR) have become important tools for airborne and satellite remote sensing. SAR delivers a high resolution image of the radar backscatter and by means of InSAR a second image from almost the same orbit is combined with the first one to provide the relative phase difference and stability/co...

Interferometric synthetic aperture radar (InSAR) techniques are today applied in many areas of remote sensing, ranging from digital elevation model (DEM) generation to surface motion mapping and InSAR tomography. To enhance the understanding of the InSAR mapping process and to test new algorithms, accurate tools for the simulation of the topographic InSAR phase are necessary. Whereas the equati...

Differential radar interferometry (D-InSAR) is a powerful remote sensing technique for detection and deformation monitoring of landslides. However, as a consequence of the radar specific imaging geometry spatial distortions, such as the layover and shadowing effect, occur in the radar image, which have a negative impact on the suitability of the radar images for D-InSAR applications. Therefore ...

Baseline parameters and interferometric phase offset need to be estimated accurately, for they are key parameters in processing of InSAR (Interferometric Synthetic Aperture Radar). If adopting baseline estimation algorithm with single pass, it needs large quantities of ground control points to estimate interferometric parameters for mosaicking multiple passes dual-antenna airborne InSAR data th...
