Monitoring city subsidence by D-InSAR in Tianjin area

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
D-InSAR technique has been widely adopted to monitor land subsidence caused by withdrawal of water, oil, gas, and other minerals. Though many cities in China have seriously suffered from land subsidence caused by ground water over-extracting, few of them have enough money to do the leveling control of the subsidence.

D-InSAR Technique for Land Subsidence Monitoring

Earth Science Frontiers, 2008
Abstract The land subsidence has been a global disastrous problem, and the conventional geodetic technique is highly incompetent in the large-scale and serious land deformation monitoring. The D-InSAR technique has been widely applied and deeply researched in the field of the land deformation monitoring.

Land subsidence monitoring by D-InSAR technique

Mining Science and Technology (China), 2011
Abstract Nowadays, the researches of using Differential Interferometric Synthetic Aperture Radar (D-InSAR) technique to monitor the land subsidence are mainly on how to qualitatively analyze the subsidence areas and values, but the analysis of subsidence process and mechanism are insufficient.

Spaceborne D-InSAR system: Conceptual overview

2015 IEEE 5th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2015
Spaceborne D-InSAR system is a kind of SAR satellite system aiming at differential interferometry application. It provides us a capability of measuring subtle deformation on the ground with phase difference. Different from existing satellite SAR missions, during the system conceptual design period, the primary objectives is improving the deformation ...

Application of D-InSAR Technology on Risk Assessment of Mining Area

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
In coal mining areas, ground subsidence persistently happens, which brings serious environmental issues and affects the safety of infrastructure. In order to effectively assess and control the security problems especially traffic problems brought by mining in Dayan mining area which located in Hulunbeier, Inner Mongolia, China.

Geosynchronous InSAR and D-InSAR

2018
Geosynchronous SAR has almost the same trajectory during its orbit period which makes it suitable for interferometric SAR and differential interferometric SAR (InSAR and D-InSAR) processing. But the very large orbit height, which is about 60 times larger than that in a low Earth orbit SAR, will cause lots of special issues in the repeated-track InSAR ...

Design of An Airborne Multi-frequency D-InSAR System

2018 IEEE 3rd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC), 2018
In the field of high precision deformation detection, the airborne D-InSAR technique has great potential. Considering the shortcomings of traditional D-InSAR technique, a multi-frequency D-InSAR system is presented in this paper. This method improves the accuracy of detection by reducing the model error, parameter error and data processing error.

Landslide Monitoring in the Three Gorges Area Using D-INSAR and Corner Reflectors

Photogrammetric Engineering & Remote Sensing, 2004
The differential INSAR technique has the potential for monitoring centimeter-scale ground motion in an accurate and costeffective manner. Probably the most important limiting factor in the application of INSAR is temporal change in the complex reflectivity of the ground surface during the period between radar acquisitions. This can be due to changes in
