Investigating landslides with space-borne Synthetic Aperture Radar (SAR) interferometry

Engineering Geology, 2006
This paper is addressed to readers without advanced knowledge of remote sensing. It illustrates some current and potential uses of satellite Synthetic Aperture Radar interferometry (InSAR) for landslide assessment. Data acquired by SAR systems can provide 3D terrain models and be used to assist in regional scale investigations, e.g. aimed at evaluation

Real-Time Optical Synthetic Aperture Radar (SAR) Processor

Optical Engineering, 1982
A description is given of a real-time optical synthetic aperture radar (SAR). The processor employs an acoustooptic device as the input electronic-to-optical transducer and a CCD camera that serves as the optical detector and simultaneously performs the focusing of the SAR image in the azimuth direction.

The SIR-C/X-SAR synthetic aperture radar system

Proceedings of the IEEE, 1991
The SIR-C/X-SAR synthetic aperture radar, a three-frequency radar to be flown on the Space Shuttle in September 1993, is described. The SIR-C system is a two-frequency radar operating at 1250 MHz (L-band) and 5300 MHz (C-band), and is designed to get four-polarization radar imagery at multiple surface angles. The X-band synthetic aperture radar (X-SAR)

SARAS: a synthetic aperture radar (SAR) raw signal simulator

IEEE Transactions on Geoscience and Remote Sensing, 1992
An SAR simulator of an extended three-dimensional scene is presented. It is based on a facet model for the scene, asymptotic evaluation of SAR unit response, and a two-dimensional fast Fourier transform code for the data processing. Prescribed statistics

Synthetic Aperture Radar (SAR) Image Quality Considerations

Optical Engineering, 1982
Characteristics of radar scattering, the synthetic aperture radar (SAR) imaging process, and display devices are considered with respect to their effects on the quality of the resulting image. A set of SAR image quality measures which relate to application information requirements are specified, and associated measurement techniques are presented.

Block compressive sensing in Synthetic Aperture Radar (SAR)

2016 24th Iranian Conference on Electrical Engineering (ICEE), 2016
High rate A/D's, heavy computations, large on board memories and downlink throughput are serious problems of high resolution Synthetic Aperture Radar (SAR). Compressive Sensing (CS) theory states that the sparsity or compressibility of a signal makes it possible to reconstruct the signal from a reduced number of samples. In the current paper, the Block

Coherent synthetic aperture radar (SAR) pair formation

2003 Proceedings of the International Conference on Radar (IEEE Cat. No.03EX695), 2004
The interference between two radar images, acquired from approximately the same location, has a number of uses. In particular, the literature abounds with examples of coherent change detection (CCD) and interferometric SAR (InSAR) uses which respectively enable the detection of small changes and the extraction of terrain elevation.

From Interferometric to Tomographic SAR: A Review of Synthetic Aperture Radar Tomography-Processing Techniques for Scatterer Unmixing in Urban Areas

IEEE Geoscience and Remote Sensing Magazine, 2020
Cross-track synthetic aperture radar (SAR) interferometry is a powerful technique that analyzes the phase shift each pixel undergoes between acquisitions of the same scene with just a slight change of viewpoint.
