ACE-OT: Polarimetric SAR data based amplitude contrast enhancement algorithm for offset tracking applications
(Institute of Electrical and Electronics Engineers (IEEE), 2022-08-01)
Article
Open AccessThe use of polarimetric synthetic aperture radar (SAR) data can improve the performance of persistent scatterer interferometry (PSI). However, its huge potential remains locked for the amplitude information-based offset ... -
An improvement of offset tracking for cross hair (CH) and patch like (PL) elimination and reliability estimation for large deformation monitoring with SAR data
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessSAR based offset tracking (OT) is an efficient tool for ground deformation observation, and signal to noise ratio (SNR) is its common error indicator. However, ground feature variations often weaken the accuracy of OT. In ... -
Analysis of pre- and post-mine closure surface deformations in western xuzhou coalfield from 2006 to 2018
(Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
Article
Open AccessEconomic development and population expansion in mining cities have led to a growing scarcity of land for construction and thus the closed mines land reuse is extremely urgent. Exploration of the law of surface deformation ... -
Improving PSI processing of mining induced large deformations with external models
(VDE-Verlag, 2021)
Conference report
Restricted access - publisher's policyThe surface deformation caused by coal mining may cause various geological disasters. Many scholars use for mine monitoring Persistent Scatterer Interferometry (PSI) combined with external models to compensate the phase ... -
Improving PSI processing of mining induced large deformations with external models
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-09-24)
Article
Open AccessGround subsidences, either caused by natural phenomena or human activities, can threaten the safety of nearby infrastructures and residents. Among the different causes, mining operations can trigger strong subsidence ... -
Initial results of the meteorological data from the first 325 sols of the Tianwen-1 mission
(Springer Nature, 2023-02-27)
Article
Open AccessAs the Zhurong rover landed on the surface of Mars in 2021, it began a months-long collection of Mars data. Equipped with highly sensitive sensors, Zhurong is capable of being a meteorological station at the surface of ... -
Patch-Like Reduction (PLR): A SAR offset tracking amplitude filter for deformation monitoring
(Elsevier, 2022-09-01)
Article
Open AccessAs complementary to Synthetic Aperture Radar (SAR) Differential Interferometry (DInSAR), SAR Offset Tracking (OT) is an efficient tool for large ground deformation monitoring in situations when DInSAR cannot work. However, ... -
Three dimensional temporal-spatial model based SAR algorithms for monitoring large gradient deformations in mining area
(Universitat Politècnica de Catalunya, 2022-05-13)
Doctoral thesis
Open AccessFirstly, an External Model Deformation Decomposition based Persistent Scatters Interferometry (EMDD-PSI) method has been proposed. This method first uses original interferograms to optimize the parameters of the external ...
