Abstract:This work presents a study of the relationship between decorrelation phase in SAR interferogram, soil moisture and water content in vegetation with the aim of mitigating the contribution of decorrelation phase in SAR interferometry (InSAR) estimates of terrain displacements. A methodology for the mitigation of the phase bias based on the temporal variation of the vegetation water content is presented. Decorrelation phases are computed using timeseries of Sentinel-1 images and compared to in-situ measurements o… Show more
