This work investigates a systematic phase bias affecting Synthetic Aperture Radar interferograms, in particular at short-term, causing biases in displacement velocity estimates that can reach several mm per year ([1]).The analysis relies on the proce

Synthetic aperture radar interferograms are affected by ionospheric disturbances. The split-spectrum method exploits the peculiar propagation of the radar waves through the ionosphere and recovers a phase screen that can be used to correct the interf

SAR interferometry is increasingly accurate in retrieving the surface deformation history over large areas of the Earth. Advancements have occurred in atmosphere delay compensation, both ionospheric and tropospheric: the remaining contributions of at

This paper deals with the mitigation of ionospheric effects in the estimation of azimuth ground motion using Sentinel-1 images. Thanks to the high accuracy of Sentinel-1 azimuth orbit timings, precise absolute measurements of azimuth ground displacem
