A Theory of Multiaperture Along-Track Interferometric Synthetic Aperture Radar
IEEE Geoscience and Remote Sensing Letters, 2019In this letter, a novel theory is proposed to measure the velocity vector of moving targets such as ocean currents by multiaperture along-track interferometric synthetic aperture radar (MA-ATI SAR), utilizing the conventional dual-antenna ATI SAR data.

An Adaptive Contoured Window Filter for Interferometric Synthetic Aperture Radar
IEEE Geoscience and Remote Sensing Letters, 2007An adaptive contoured window filter is proposed to filter off the noise from phase images of interferometric synthetic aperture radar (InSAR) in this letter. The contoured windows can best satisfy the requirement that constrains the phase signal constant inside windows on which low-pass filtering can remove the noise well while the fringe phases are ...

Interferometric Synthetic Aperture Microscopy: Microscopic Laser Radar
Optics and Photonics News, 2010Using instruments from optical coherence tomography and the principles of synthetic aperture radar, researchers have developed a new method for reconstructing 3-D optical images. Doctors may soon be able to use this approach as a noninvasive diagnostic tool in clinical settings.

Interferometric synthetic aperture processing: a comparison of sonar and radar
The Journal of the Acoustical Society of America, 2008Interferometric aperture synthesis is an inverse problem that attempts to form an elevation map of the earth (in the case of radar) or a bathymetric map of the seafloor (in the case of sonar). In both cases, a pair of (nominally) vertically displaced transducers is configured as an interferometer. After aperture synthesis is performed to produce a pair

Studies of multibaseline spaceborne interferometric synthetic aperture radars
IEEE Transactions on Geoscience and Remote Sensing, 1990The authors have utilized a set of Seasat synthetic aperture radar (SAR) data that were obtained in nearly repeat ground-track orbits to demonstrate the performance of spaceborne interferometric SAR (INSAR) systems. An assessment of the topography measurement capability is presented.

Directionally Adaptive Filter for Synthetic Aperture Radar Interferometric Phase Images
IEEE Transactions on Geoscience and Remote Sensing, 2013The obvious directionality inherent in interferometric synthetic aperture radar interferograms allows noise to be filtered very effectively along the fringe direction, leaving the fringe phase undamaged. This paper proposes a highly reliable method for the simultaneous estimation of the direction and density of interferograms, on the basis of which a ...

Motion compensation for airborne interferometric synthetic aperture radar
2009Airborne SAR interferometry has the potential to provide topographic data with a precision of the order of one meter. However, to generate data accurate to this level it is essential to measure and compensate for the antenna baseline motion. Conventional motion compensation techniques and their errors are analyzed and extended to the two channel ...
