Non-differential water vapor estimation from SBAS-InSAR

Journal of Atmospheric and Solar-Terrestrial Physics, 2020
Abstract Water vapor is the most variable constituent in the atmosphere and plays an important role in climate studies, mesoscale meteorology modeling and numerical weather forecasting. Being able to penetrate clouds, interferometric synthetic aperture radar (InSAR) shows great potential in atmospheric water vapor mapping.

Sequential Estimation of Dynamic Deformation Parameters for SBAS-InSAR

IEEE Geoscience and Remote Sensing Letters, 2020
The synthetic aperture radar (SAR) interferometry (InSAR) has been developed for more than 20 years for historical surface deformation reconstruction. In particular, the onboard Sentinel-1/A/B satellite, newly planned NASA-ISRO SAR (NISAR), and Germany Tandem-L will continue to provide unprecedented SAR data with an increased number of acquisitions ...

Surface Deformation Analysis in Jiuzhaigou, China Using SBAS-InSAR Technique

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
In this paper, the surface deformation of Jiuzhaigou County is analyzed. The ascending ALOS-2 data of 15 scenes from December, 2017 to September, 2019 is used, and the results of surface deformation in time series are extracted by the small baseline subset interferometric synthetic aperture radar (SBAS-InSAR) technique. The monitoring results show that

Mapping overall taiyuan graben basin deformation with SBAS-InSAR technique

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Taiyuan graben basin has been suffering serious ground deformation due to the combined effects of groundwater pumping, ground fissures and faults. However, most ground deformation monitoring mainly focus on the single city, thus it is difficult to reveal the regional extent of the deformation.

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.

Monitoring of surface deformation in mining area integrating SBAS InSAR and Logistic Function

Environmental Monitoring and Assessment, 2023
SBAS InSAR has long been used to monitor the mining surface deformation, and its research has been of great interest to researchers worldwide. For the unsatisfactory accuracy of SBAS InSAR-monitored mining surface deformation results, a new corrected model is proposed by integrating SBAS InSAR and Logistic Function. Firstly, the time series deformation

Revealing Long-Term Displacement and Evolution of Open-Pit Coal Mines Using SBAS-InSAR and DS-InSAR

Remote Sensing
Coal mines play an important role in the global energy supply. Monitoring the displacement of open-pit mines is crucial to preventing geological disasters, such as landslides and surface displacement, caused by high-intensity mining activities. In recent
