Monitoring deformation in glasshouses using InSAR

The Netherlands has for long been witnessing problems due to subsidence. While urban infrastructure is mostly safeguarded from differential settlement by deep pile foundations, the same cannot be said about greenhouses. The greenhouses of the Netherlands has enabled the country to become the largest exporter of vegetables, second only to the...

The detection of deformation on vegetated dikes using InSAR

Almost four million people in the Netherlands who live below sea level are protected by 17000 km of dikes against the water. Since deformation can be an indicator of a developing failure mechanism, information about this parameter can help authorities to detect weak spots in the dutch water defense structures. <br/>In this research, Radar...

A feasibility study of building monitoring and forensic engineering with Interferometric Synthetic Aperture Radar

The last years have seen a few severe cases of structural damage to buildings in the Netherlands. A recent case was the shopping mall ‘t Loon in Heerlen. It would be beneficial if structural failures could be avoided, or at least be predicted. New satellite technology, Interferometric Synthetic Aperture Radar (InSAR), proves that it is possible...

Identification and analysis of point scatterers in time series InSAR

In this study methods are developed for improved analysis and processing of PSI data. PSI, or radar interferometry, makes it possible to use satellite radar images to measure deformation of the Earth’s surface and objects on it with millimetre accuracy. However, interpretation of the measurements and identifying the actually measured objects is...
