Advanced operation mode techniques for an interferometric Synthetic Aperture Radar

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Synthetic Aperture Radar (SAR) operating at Ka-band frequency is increasingly being considered for spaceborne applications. The benefits are seen in the compactness of the instruments, the high bandwidth and resolution. Besides this the high carrier frequency facilitates single-pass interferometry by allowing for an accommodation of all transmitters ...

Interferometric synthetic-aperture radar (InSAR)

2007
Geodesists 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.

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 for terrain mapping

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
The paper describes a new technique for topographic mapping using an interferometric synthetic aperture radar (IFSAR). The IFSAR utilizes microwave interference for precise measurement of small linear displacements related to the surface topography. It is similar to a traditional SAR system except that it has two receive antennas (with essentially the ...

Introduction to Interferometric Synthetic Aperture Radar

2014
Radar 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).

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 ...

Theory and design of interferometric synthetic aperture radars

IEE Proceedings F Radar and Signal Processing, 1992
A 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 ...
