Integration of InSAR time series analysis and water vapour correction for mapping postseismic deformation after the 2003 Bam (Iran) Earthquake [PDF]

, 2009
Atmospheric water-vapor effects represent a major limitation of interferometric synthetic aperture radar (InSAR) techniques, including InSAR time-series (TS) approaches (e.g., persistent or permanent scatterers and small-baseline subset).

A MULTI-STEP DE-NOISING METHOD FOR INTERFEROGRAM IN PS-INSAR

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Abstract. In order to reduce the influences of the noises in Synthetic Aperture Radar (SAR) image on accurate extraction of permanent scattered (PS) points in PS-InSAR technology, a multi-step de-noising approach considering the characteristics of the noises is proposed in this study.
