Multicriteria analysis for landslide inventory mapping using PS-InSAR

2019 IEEE Recent Advances in Geoscience and Remote Sensing : Technologies, Standards and Applications (TENGARSS), 2019
In this research work, a multicriteria analysis is performed for the preparation of landslide inventory maps in Uttarakhand, India primarily using PS-InSAR approach. A pre-existing landslide inventory map, initially prepared by Geological Survey of India (GSI) is validated through processing of 10 Sentinel-1A and 15 Envisat ASAR images corresponding to

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 ...

A PS- InSAR Sequential Processing Method Based on Network Reconstruction

2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2018
Permanent scatterers in SAR interferometry (PS-InSAR) is used in the long time monitoring of deformation on the earth's surface. However, the traditional PS-InSAR is a method of batch handing to accomplish detecting and networking the permanent scatterers (PS) and parameter calculation, which greatly reduce the processing efficiency.

Recursive data processing and data volume minimization for PS-InSAR

Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005
PS-InSAR has proven to be an accurate and ef- ficient technique for the joint estimation of topographic and displacement signal from stacked interferometric combinations. In this contribution a new method for PS-Insert processing is introduced, which enables the recursive estimation of parameters of interest.

Integrating PS-InSAR and SBAS-InSAR for mining surface settlement monitoring

Journal of Mines, Metals and Fuels, 2022
Based on 38 Sentinel-1A images, this paper imports GCP points generated by PS-InSAR into SBAS-InSAR, instead of manually selected GCP points, extracts surface deformation in the study area, and compares and analyzes with traditional GPS monitoring data.

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.

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.

Land deformation monitoring using PS-InSAR technique over Sahel-Doukkala (Morocco)

2017 International Conference on Advanced Technologies for Signal and Image Processing (ATSIP), 2017
Even if land deformation in Sahel-Doukkala may not directly threaten human life, it could lead to serious economic losses. Therefore, the monitoring of this deformation becomes a priority. In this study, PS-InSAR technique was applied in order to extract information regarding land deformation.
