Radar Applications of Interferometry

1991
There 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.

The Use of Radar Interferometry in Landslide Monitoring

2013
This chapter presents some specific considerations on the use of SAR interferometry to landslide studies. Both space-borne and ground-based methods are briefly reviewed and main issues in the application of them discussed on the basis of real examples.

Synthetic Aperture Radar Interferometry: Utilizing Radar Principles

IEEE Geoscience and Remote Sensing Magazine, 2020
One 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.

MF radar interferometry

1992
This thesis describes the development, operation and observations of interferometry experiments on two medium frequency spaced antennae radar operated by the Department of Physics and Astronomy of the University of Canterbury; the 2.4 MHz radar at Birdlings Flat near Christchurch, New Zealand, and the 2.9 MHz radar at Scott Base on Ross Island in the ...

Tropospheric heterogeneities corrections in differential radar interferometry

IEEE International Geoscience and Remote Sensing Symposium, 2003
Differential radar interferometry (DInSAR) has been used more and more widely to monitor crustal deformations due to underground mining and oil extraction, earthquakes, volcanoes, landslides, and so on. However, tropospheric heterogeneities have been identified as one of the major errors in DInSAR, which can be up to 40 cm as derived from dual ...

Integration of GPS and radar interferometry

GPS Solutions, 2003
Synthetic Aperture Radar Interferometry (or InSAR) is a technique first suggested in the early 1970s. The technique produces an ‘interferogram’ from the phase difference between two SAR images acquired over the same region. If the two SAR images are acquired from two repeated SAR coverages of the same region, the technique is referred to as ‘repeat ...

Venus: Mapping the Surface Reflectivity by Radar Interferometry

Science, 1969
The surface reflectivity of Venus obtained by radar interferometry at a wavelength of 3.8 centimeters has been mapped for a region extending approximately from -80° to 0° in longitude (Carpenter's definition) and from -50° to +40° in latitude. The map is free from the twofold range-Doppler ambiguity because the interferometer fringe pattern makes ...

Synthetic Aperture Radar Interferometry

2010
In the past two decades INSAR technique (synthetic aperture radar interferometry) has been quickly developed and widely used for the study of topography (digital elevation model generation) and deformation (Earth surface monitoring). Synthetic aperture radar (SAR) is a coherent active microwave image instrument, which is used for mapping the scattering
