InSAR Forensics: Tracing InSAR Scatterers in High Resolution Optical Image [PDF]

open access: yesProceedings of Fringe 2015: Advances in the Science and Applications of SAR Interferometry and Sentinel-1 InSAR Workshop, 2015
The current synthetic aperture radar (SAR) theory makes a quite restrictive assumption – linearity – in the SAR imaging model, for the convenience of mathematical derivation. That is to say the imaged area is considered as an ensemble of individual point scatterers whose scattered fields and, hence, their responses in the SAR image superimpose linearly

Characteristics of normal-fault earthquake deformation in the Qinghai-Tibet Plateau revealed by InSAR

open access: yes地球与行星物理论评, 2023
The north-south convergence and east-west extension of the Tibet Plateau are accommodated by a series of active strike-slip and normal faults, and normal-fault earthquakes are very active in the plateau. During 2020 to 2021, there were three normal-fault

Robust multibaseline InSAR optimization [PDF]

open access: yes2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Multibaseline SAR interferometry may face unmodeled interferometric phase such as unmodeled motion phase and uncompensated atmospheric phase, as well as non-Gaussian statistics in the context of distributed scatterer. We developed the robust InSAR optimization (RIO) [1] framework to systematically tackle these issues.

InSAR Elevation Inversion Method Based on Backprojection Model with External DEM

open access: yesLeida xuebao, 2021
When Interferometric Synthetic Aperture Radar (InSAR) is used to obtain the Digital Elevation Model (DEM), highly sloped terrains will make interferometric fringes dense and increase the difficulty of phase unwrapping, which will affect the accuracy of ...

Landslide Activity Maps Generation by Means of Persistent Scatterer Interferometry

open access: yesRemote Sensing, 2013
In this paper a methodology is proposed to elaborate landslide activity maps through the use of PS (Persistent Scatterer) data. This is illustrated through the case study of Tramuntana Range in the island of Majorca (Spain), where ALOS (Advanced Land ...

Identification of geological hazards based on the combination of InSAR technology and disaster background indicators

open access: yes地质科技通报, 2022
Synthetic aperture radar interferometry (InSAR) is an important method to obtain surface deformation information. Due to the limitations of InSAR data acquisition and the accuracy errors produced in the data processing, the identification of hidden ...
