Synthetic aperture radar interferometry
Inverse Problems, 1998Summary: Synthetic aperture radar (SAR) is a coherent active microwave imaging method. In remote sensing it is used for mapping the scattering properties of the Earth's surface in the respective wavelength domain. Many physical and geometric parameters of the imaged scene contribute to the grey value of a SAR image pixel.

Estimation of snow water equivalent from L-band radar interferometry: simulation and experiment
, 2020The Snow Water Equivalent (SWE) is the main feature of a snowpack that determines its impact on the natural environment. Because microwaves penetrate through the snowpack, microwave remote sensing enables the measurement of depth and snow water ...

Synthetic Aperture Radar Interferometry: Utilizing Radar Principles
IEEE Geoscience and Remote Sensing Magazine, 2020One of the most important applications of synthetic aperture radar interferometry (SARIF) is making a geometrical plot of observed points on the ground surface. For that purpose, we derive the two points' distances using a radar principle. Mathematically, this problem is a two-unknown-variables problem. To solve, it we need only two equations.

Radar and sonar interferometry
The Journal of the Acoustical Society of America, 2008This paper is an attempt to compare two interferometric processings. The first one is applied to traditional space-borne radar (SAR) and the second on recent interferometric sonar data. Few comparisons between those tech-niques have already been made, despite the fact that they share many similar principles, only a.

Radar interferometry: limits and potential
IEEE Transactions on Geoscience and Remote Sensing, 1993The contribution of radar interferometry to the field of digital terrain modeling is important because this technique offers specific features which optical instruments cannot attain. However, the complexity of the height restitution and the accuracy of the result strongly depend on the orbital geometry at the time of the data takes.

Radar Applications of Interferometry
1991There are not only applications of interferometry for radio astronomy but also for radar techniques. Particularly the increasingly important field of space research requires methods which yield measurements of position and velocity of flying objects to the highest precision.

Satellite Radar Interferometry
Synthetic Aperture Radar Interferometry (InSAR) is an active remote sensing method that uses repeated radar scans of the Earth's solid surface to measure relative deformation at centimeter precision over a wide swath. It has revolutionized our understanding of the earthquake cycle, volcanic eruptions, landslides, glacier flow, ice grounding lines ...David T. Sandwell +7 more
