Interferometric synthetic aperture radar atmospheric correction: Medium Resolution Imaging Spectrometer and Advanced Synthetic Aperture Radar integration [PDF]

Geophysical Research Letters, 2006
Atmospheric water vapor effects represent one of the major limitations of repeat‐pass InSAR, and limit the accuracy of deformation rates derived from InSAR. The use of contemporaneous MERIS data to correct ENVISAT ASAR measurements shows a significant reduction in water vapor effects.

Urban Sensing with Spaceborne Interferometric Synthetic Aperture Radar [PDF]

, 2021
AbstractSynthetic aperture radar (SAR) and interferometric SAR (InSAR) are state-of-the-art radar remote sensing technologies and are very useful for urban remote sensing. The technologies have some very special characteristics compared to optical remote sensing and are especially advantageous in cloudy regions due to the ability of the microwave radar

Advanced InSAR atmospheric correction: MERIS/MODIS combination and stacked water vapour models [PDF]

, 2009
A major source of error for repeat-pass Interferometric Synthetic Aperture Radar (InSAR) is the phase delay in radio signal propagation through the atmosphere (especially the part due to tropospheric water vapour).

SAR Interferometric Baseline Refinement Based on Flat-Earth Phase without a Ground Control Point

Remote Sensing, 2020
Interferometric baseline estimation is a key procedure of interferometric synthetic aperture radar (SAR) data processing. The error of the interferometric baseline affects not only the removal of the flat-earth phase, but also the transformation ...

Ionospheric correction of ALOS-2 full-aperture ScanSAR interferometric data for surface deformation measurement in Beijing

The Journal of Engineering, 2019
Ionospheric disturbance is one of the most serious factors that limit the accuracy of deformation measurement of interferometric synthetic aperture radar (InSAR) especially for spaceborne SAR systems in low frequency such as L-band. Especially in imaging
