A method for correcting InSAR interferogram errors using GNSS data and the K-means algorithm Earth Planets Space (IF 3.362) Pub Date : 2024-04-06 Huineng Yan, Wujiao Dai, Wenbin Xu, Qiang Shi, Kai Sun, Zhigang Lu, Rui Wang
Correcting interferometric synthetic aperture radar (InSAR) interferograms using Global Navigation Satellite System (GNSS) data can effectively improve their accuracy. However, most of the existing correction methods utilize the difference between GNSS and InSAR data for surface fitting; these methods can effectively correct overall long-wavelength errors, but they are insufficient for multiple medium-wavelength

Abstract According to a 2013 report by the Earthquake Research Committee of Japan, it was estimated that the probability of the occurrence of the next Nankai earthquake within the next three decades is 70–80%. Therefore, to realize hazard estimation, it is crucial to estimate the state of the plate interface in the Nankai Trough subduction zone. In this study, we focused on a transient from 2018 in
