Generation of interferogram for D-InSAR based on contoured correlation interferometry

SPIE Proceedings, 2009
Synthetic Aperture Radar interferometry (InSAR) is a rapidly developing technique for earth observation. Differential InSAR (D-InSAR) technique, based on InSAR, is a new method for earthquake deformation detection and land subsidence monitoring.

Three Dimensional Deformation Retrieval in GEO D-InSAR

2018
GEO SAR has characteristics of short revisit time of less than one day, extended coverage area with even larger than 1000 km and long coverage time of several hours for the scene of interest, and thus can provide data of a certain region of interest with lots of view angles.

The analysis of surface deformation based on two-pass and three-pass D-InSAR

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
The Differential Synthetic Aperture Radar Interferometry (D-InSAR) is widely used in large-scale ground deformation monitoring such as crustal deformation, seismic changes, land subsidence, landslides, volcanic deformation, glacial movement. In this paper, The deformation analysis based on two-pass differential and three-pass differential InSAR is done.

Research on ionospheric effects and error calibration for L-band spaceborne D-InSAR

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
At L-band, the ionosphere is assumed to have considerable effects on differential Synthetic Aperture Radar Interferometry (D-InSAR) image quality [1]. This paper focuses on ionospheric propagation effects from difference of slant range total electron content (ΔSTEC) and error calibration for D-InSAR. Referring to International Reference Ionosphere (IRI)

Slope Sliding Direction Estimate Based on Ground-based D-InSAR

2019 6th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2019
Landslide is a common natural geological disaster, and the development process of landslide is so complicated, then makes the prevention and control of landslide very difficult. In the process of landslide monitoring and control, the estimation of slope sliding direction is very important.
