Abstract
Vajedian et al. [1] present an improved method for the derivation of deformation parameters using satellite Interferometric Synthetic Aperture Radar (InSAR) data. The method is a modification of the Small Baseline Subset (SBAS) method as implemented in the StaMPS (Stanford Method for Persistent Scatterers) software. The modification includes many steps including the filtering of the differential interferograms, integration with GPS data and advanced phase unwrapping “to overcome a lot of short- and long-wavelength artifacts that are clearly visible in StaMPS results” (cf. [1], p. 8331). The authors refer to this new approach as the Improved SBAS, or ISBAS, method. [...]

Vajedian et al [1] present an improved method for the derivation of deformation parameters using satellite Interferometric Synthetic Aperture Radar (InSAR) data
The method is a modification of the Small Baseline Subset (SBAS) method as implemented in the StaMPS (Stanford Method for Persistent Scatterers) software
The modified approach appears perfectly valid, the authors have overlooked the fact that the ISBAS acronym is already well-established and has been used in over 20 publications since 2012, including journal papers, conference presentations and proceedings, abstracts, web pages and magazine articles
