Some thoughts on the use of InSAR data to constrain models of surface deformation: Noise structure and data downsampling [PDF]

open access: yes, 2005
Repeat-pass Interferometric Synthetic Aperture Radar (InSAR) provides spatially dense maps of surface deformation with potentially tens of millions of data points. Here we estimate the actual covariance structure of noise in InSAR data.

Interferometric Synthetic Aperture Radar

open access: yes, 2022
Interferometric Synthetic Aperture Radar (InSAR) has catapulted our ability to detect, quantify and characterize bio- and geophysical processes (e.g., aquifer dynamics, tectonic, and magmatic processes, etc.). During the last four decades, InSAR has imaged the complete Earth’s surface and transformed our understanding of how Earth works.

High quality InSAR data linked to seasonal change in hydraulic head for an agricultural area in the San Luis Valley, Colorado [PDF]

open access: yes, 2011
In the San Luis Valley (SLV), Colorado legislation passed in 2004 requires that hydraulic head levels in the confined aquifer system stay within the range experienced in the years 1978–2000.

Multiview Three-Dimensional Interferometric Inverse Synthetic Aperture Radar

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 2019
Three-dimensional (3D) inverse synthetic aperture radar (ISAR) imaging has been proven feasible by combining traditional ISAR imaging and interferometry. Such technique, namely Inteferometric ISAR (InISAR), allows for the main target scattering centers to be mapped into a 3-D spatial domain, therefore forming 3-D images under the form of 3-D point ...

Motion Compensation of Interferometric Synthetic Aperture Radar

open access: yesIEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2004
Synthetic aperture radar (SAR) is a digital signal processing technique which enhances the azimuth resolution of a radar image using the target Doppler history created by the motion of the radar platform. If the platform deviates from a constant velocity, straight-line path then image quality is lost and image details become unfocused.
