Hu, F. (author), Helfer, K.C. (author), Siebesma, A.P. (author), Hanssen, R.F. (author)Atmospheric delay has a profound impact on synthetic aperture radar (SAR) interferometry, inducing a spatial signal that significantly devaluates interferometric products. While the wide-scale variability of the atmosphere can be adequately modeled with global or regional weather models, it is especially the turbulent and convective part of the...journal article 2022

Hu, F. (author), van Leijen, F.J. (author), Chang, L. (author), Wu, Jicang (author), Hanssen, R.F. (author)Synthetic aperture radar (SAR) missions with short repeat times enable opportunities for near real-time deformation monitoring. Traditional multitemporal interferometric SAR (MT-InSAR) is able to monitor long-term and periodic deformation with high precision by time-series analysis. However, as time series lengthen, it is time-consuming to...journal article 2022

Hu, F. (author), Wu, Jicang (author), Chang, Ling (author), Hanssen, R.F. (author)Multi-temporal interferometric synthetic apertureradar (MT-InSAR) is used for many applications in earthobservation. Most MT-InSAR methods select scatterers with highcoherence throughout the entire time series. However, as timeseries lengthen, inevitable changes in surface scattering leadto decorrelation, which systematically decreases the...journal article 2019

Hu, F. (author), van Leijen, F.J. (author), Chang, Ling (author), Wu, Jicang (author), Hanssen, R.F. (author)Multi-temporal interferometric synthetic aperture radar (MT-InSAR) can be applied to monitor the structural health of infrastructure such as railways, bridges, and highways. However, for the successful interpretation of the observed deformation within a structure, or between structures, it is imperative to associate a radar scatterer...journal article 2019
