Tomosar and PS-InSAR analysis of high-rise buildings in Berlin

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Using high-resolution SAR data stacks, a large amount of persistent scatterers (PS) can be found in urban areas, which are used for very detailed surface deformation monitoring. However, in dense urban areas, many of these points consist of more than one dominant scatterer in elevation direction.

Landslide monitoring by PS-InSAR along Qing river

2012 Second International Workshop on Earth Observation and Remote Sensing Applications, 2012
This paper used PS-InSAR method to monitor the landslide along Qing river. Several typical landslides area were selected as the experimental areas. 61 ASAR data have been processed, which were acquired from 2003 to 2010. The obtained preliminary deformation rate map not only included the experimental areas, but also showed several new landslides areas.

Advanced PS-INSAR for Land Subsidence Monitoring in Cangzhou

Applied Mechanics and Materials, 2012
The conventional D-InSAR technique has been successfully applied in the volcano, earthquake induced surface deformation monitoring of large scale. However it is restricted by the loss of coherence and atmospheric delay effect. Advanced PS-INSAR as IPTA (Interferometric Point Target Analysis) technology was used to monitor urban area in Cangzhou city ...

Study of urban instability phenomena in Bucharest city based on Ps-InSAR

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
This work focuses on monitoring the ground motion and infrastructure stability in an urban environment, namely in the city of Bucharest. Bucharest is a fast developing city with the average construction rate of 8-20% new buildings with respect to the existing ones. Consequently, the civil engineering industry faced new challenges related to the need of

Improvement of PS-InSAR atmospheric phase estimation by using WRF model

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
As a component of interferometric phase, atmospheric phase influences accuracy of millimetric land deformation measurement. Though Atmospheric Phase Screen (APS) can be estimated by Persistent Scatterer Interferometric Synthetic Aperture Radar (PS-InSAR) technology, they are pseudo without consideration of actual atmospheric state and topography.

Analyzing the topographic influence for the PS-INSAR processing in the Three Gorges region

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Persistent Scatterer Interferometry (PS-InSAR) is applied to derive displacement information with millimetric precision. Analyzing stable persistent scatterers from a large stack of SAR images,helps to overcome the geometrical and temporal decorrelation, which occur when using differential interferometry.
