Synthetic aperture radar interferometry
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. Scene inversion suffers from this high ambiguity and requires SAR data taken at di...
متن کاملStudy of subsidence of Abarkooh plain of Yazd using the Synthetic Aperture Radar Interferometry method
Abstract The population growth, the development of cities, industry, agriculture, and improper use of resources especially non-renewable resources have led human beings to face the danger of running out of resources. In some cases, in addition to the above, irreversible environmental and geological hazards have occurred due to the overdrawn of resources. Over extraction of groundwater resourc...

متن کاملA Mathematical Tutorial on Synthetic Aperture Radar
This paper presents the foundations of conventional strip-mode synthetic aperture radar (SAR) from a mathematical point of view. In particular, the paper shows how a simple antenna model can be used together with a linearized scattering approximation to predict the received signal. The conventional matched-filter processing is explained and analyzed to exhibit the resolution of the SAR system.
متن کاملCoregistration Based on Sift Algorithm for Synthetic Aperture Radar Interferometry
Single-look complex image coregistration is the key step of Synthetic Aperture Radar(SAR) Interferometry. The precision of the coregistration results have a direct effect on the quality of the SAR interferogram generated, thereby it will influence the accuracy of extracting DEM. In this paper, SIFT (Scale Invariant Feature Transform) algorithm will be used in Single-look complex image coregistr...
