Polarimetric Interferometric Synthetic Aperture Radar

2021
Polarimetric Interferometry SAR (PolInSAR) is a new earth observation technology developed on the basis of polarimetric SAR and interferometric SAR technology [1]. It uses the effective combination of polarization and interference information to obtain three-dimensional structural feature information and scattering information of the observation object.

Topographic mapping from interferometric synthetic aperture radar observations

Journal of Geophysical Research: Solid Earth, 1986
Interferometric synthetic aperture radar observations provide a means for obtaining high‐resolution topographic terrain maps from data acquired simultaneously at two slightly displaced antennas. Calculation of the three‐dimensional coordinates of all the points in a radar image can be made from the combination of along‐track, slant range, and ...

Compact Ground-Based Interferometric Synthetic Aperture Radar: Short-Range Structural Monitoring

IEEE Signal Processing Magazine, 2019
Recently, structural monitoring by radar remote sensing has become more necessary for both economic and security reasons. Infrastructure monitoring with no incorporated deformation sensors (e.g., old generation water dams for which regulations did not impose monitoring capabilities) is usually performed by regular in situ topographic surveys.

Interferometric polarimetric synthetic aperture radar system

SPIE Proceedings, 2001
Polarimetric radar interferometry is a compound technique that has shown the ability to extract geophysical parameters from synthetic aperture radar (SAR) images and its usefulness in terrain classification and surface change detection. A three-dimensional image can be constructed by coherence integrating the backscatter data over the measured ...

Interferometric Synthetic Aperture Radar Geodesy

2007
Satellite-based interferometric synthetic aperture radar (InSAR) provides a synoptic high spatial resolution perspective of Earth's deforming surface, permitting one to view large areas quickly and efficiently. We review basic InSAR theory for geodetic applications and attempt to provide an overview of what processing and analysis schemes are currently
