Journal ArticleDOI
Linear and nonlinear terrain deformation maps from a reduced set of interferometric SAR images
TL;DR: An advanced technique for the generation of deformation maps using synthetic aperture radar (SAR) data is presented, which estimates the linear and nonlinear components of the displacement, the error of the digital elevation model (DEM), and the atmospheric artifacts from a reduced set of low spatial resolution interferograms.
Journal ArticleDOI
Medical imaging with a microwave tomographic scanner
Lluis Jofre,Mark S. Hawley,Antoni Broquetas,E. de los Reyes,Miguel Ferrando,A.R. Elias-Fuste +5 more
TL;DR: Measurements on tissue-simulating phantoms and volunteers, together with numerical simulations, are presented to assess the system for absolute imaging of tissue distribution and for differential imaging of physiological, pathological, and induced changes in tissues.
Journal ArticleDOI
Spherical wave near-field imaging and radar cross-section measurement
TL;DR: In this paper, a new inverse synthetic aperture radar (ISAR) algorithm is proposed for radar cross-section imaging and measurement from scattered fields, based on a spherical-wave near-field illumination of the target, overcomes the requirement for an expensive compact range facility to produce a plane wave illumination.
Journal ArticleDOI
Cylindrical geometry: a further step in active microwave tomography
TL;DR: In this article, a prototype imaging system for active microwave tomography using cylindrical geometry has been developed, making it possible to obtain images of the dielectric properties of biological targets at 2.45 GHz.
Journal ArticleDOI
Geosynchronous SAR Focusing With Atmospheric Phase Screen Retrieval and Compensation
TL;DR: A geosynchronous synthetic aperture radar (SAR) (GEOSAR) mission for atmospheric phase screen (APS) retrieval using a long coherent integration of pulses is analyzed and an APS correction algorithm from short-term periodic acquisitions (subapertures) of the whole long-term GEOSAR synthetic aperture is described.
