Interferometric Synthetic Aperture Radar Geodesy
2007Satellite-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

Interferometric polarimetric synthetic aperture radar system
SPIE Proceedings, 2001Polarimetric 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 ...

Theory and design of interferometric synthetic aperture radars
IEE Proceedings F Radar and Signal Processing, 1992A derivation of the signal statistics, an optimal estimator of the interferometric phase, and the expression necessary to calculate the height-error budget are presented. These expressions are used to derive methods of optimizing the parameters of the interferometric synthetic aperture radar system (InSAR), and are then employed in a specific design ...

Introduction to Interferometric Synthetic Aperture Radar
2014Radar is an acronym for radio detection and ranging, which hints at some of the technique’s uses and capabilities. Radars operate in the microwave portion of the electromagnetic spectrum, which encompasses wavelengths (λ) from 1 meter (m) to 1 mm (mm), or equivalently, frequencies (f ) from 300 megaHertz (MHz) to 300 gigaHertz (GHz).

Terrain height measurement accuracy of interferometric synthetic aperture radars
IEEE Transactions on Geoscience and Remote Sensing, 1996Presents a simple expression for the accuracy with which an interferometer synthetic-aperture radar (IFSAR) can measure terrain elevation. The expression, derived analytically and confirmed by Monte Carlo simulation, accounts for thermal noise, resolution cell size, terrain slope and roughness, volume scattering above the terrain, radar-terrain ...

Interferometric synthetic-aperture radar (InSAR)
2007Geodesists are, for the most part, a patient and hardworking lot. A day spent hiking to a distant peak, hours spent waiting for clouds to clear a line-of-sight between observation points, weeks spent moving methodically along a level line — such is the normal pulse of the geodetic profession.

A Theory of Multiaperture Along-Track Interferometric Synthetic Aperture Radar
IEEE Geoscience and Remote Sensing Letters, 2019In this letter, a novel theory is proposed to measure the velocity vector of moving targets such as ocean currents by multiaperture along-track interferometric synthetic aperture radar (MA-ATI SAR), utilizing the conventional dual-antenna ATI SAR data.

An Adaptive Contoured Window Filter for Interferometric Synthetic Aperture Radar
IEEE Geoscience and Remote Sensing Letters, 2007An adaptive contoured window filter is proposed to filter off the noise from phase images of interferometric synthetic aperture radar (InSAR) in this letter. The contoured windows can best satisfy the requirement that constrains the phase signal constant inside windows on which low-pass filtering can remove the noise well while the fringe phases are ...

Interferometric Synthetic Aperture Microscopy: Microscopic Laser Radar
Optics and Photonics News, 2010Using instruments from optical coherence tomography and the principles of synthetic aperture radar, researchers have developed a new method for reconstructing 3-D optical images. Doctors may soon be able to use this approach as a noninvasive diagnostic tool in clinical settings.

Interferometric synthetic aperture processing: a comparison of sonar and radar
The Journal of the Acoustical Society of America, 2008Interferometric aperture synthesis is an inverse problem that attempts to form an elevation map of the earth (in the case of radar) or a bathymetric map of the seafloor (in the case of sonar). In both cases, a pair of (nominally) vertically displaced transducers is configured as an interferometer. After aperture synthesis is performed to produce a pair
