Compressed sensing application in interferometric synthetic aperture radar
Science China Information Sciences, 2017A novel interferometric synthetic aperture radar (InSAR) signal processing method based on compressed sensing (CS) theory is investigated in this paper. InSAR image formation provides the scene reflectivity estimation along azimuth and range coordinates with the height information.

Advanced operation mode techniques for an interferometric Synthetic Aperture Radar
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012Synthetic 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 for terrain mapping
1995 International Conference on Acoustics, Speech, and Signal Processing, 2002The 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 ...

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.
