This paper reviews research since 1988 into the capabilities of synthetic aperture radar (SAR) for monitoring, classification, and characterization of the Bonanza Creek Experimental Forest on the floodplain of the Tanana River and adjacent uplands.
The Alaska SAR Facility is currently undergoing an upgrade development effort to accommodate the upcoming ERS-2 and RADARSAT satellites.
In this talk we present results of a repeat-pass SAR interferometry experiment performed in June 1993 near Portage, Maine. Differential GPS data accurate to +/-10cm were acquired to aid in motion compensation and geolocation of targets in the imagery. The experiment and data analysis will be discussed, and results will be shown during the presentation.
Across-track interferometric SAR provides high resolution both horizontally and vertically which is of importance to topographic mapping applications.
This paper presents results from a study of multiple-polarization C-band SAR signitures of sea ice for applications to sea ice mapping with ENVISAT ASAR data.
At depth, many fold-and-thrust belts are composed of a gently dipping, basal thrust fault and steeply dipping, shallower splay faults that terminate beneath folds at the surface. Movement on these buried faults is difficult to observe, but synthetic aperture radar (SAR) interferometry has imaged slip on at least 600 square kilometers of the Shahdad basal-thrust and splay-fault network in southeast Iran.
In this paper we present a complete procedure for the extraction and characterization of building structures starting from the three-dimensional (terrain elevation) data provided by interferometric SAR measurements.
Imaging of the ocean surface with a synthetic aperture radar (SAR) provides unprecedented detailed views of the ocean's short wave field as it responds to interactions with the atmosphere, longer waves and currents.
The least-mean-square (LMS) adaptive filter is applied to suppress narrow-band radio-frequency interference (RFI) in wideband sythetic aperture radar (SAR) signals.
Fifteen synthetic-aperture radar (SAR) images of the Ronne Ice Shelf, Antarctica, obtained by the European Space Agency (ESA)'s Earth Remote Sensing satellites (ERS) 1 & 2 are used to study ice-shelf dynamics near two ends of the iceberg-calving front.
We compare Earth Remote Sensing (ERS) satellite synthetic-aperture radar (SAR) interferograms with artificial interferograms constructed using output of a finite-element ice-shelf flow model to study the dynamics of Filchner-Ronne Ice Shelf (FRIS) near Hemmen Ice Rise (HIR) where the iceberg-calving front itersects Berkener Island (BI).
Comparison between numerical model ice-shelf flow simulations and synthetic aperture radar (SAR) interferograms is used to study the dynamics at the Hemmen Ice Rise (HIR) and Lassiter Coast (LC) corners of the iceberg-calving front of the Filchner-Ronne Ice Shelf (FRIS).
SAR image data from a variety of spaceborne and airborne sensors will be much more.
The Alaska SAR Facility (ASF) situated at the University of Alaska Fairbanks (UAF) is currently undergoing an extensive development effort to increase its capabilities in handling new sensors and in the areas of throughput, data handling, archive, and distribution [15].
The logistical difficulties of making regular oceanographic measurements in the polar oceans during winter make it necessary to employ remote-sensing techniques. Microwave synthetic aperture radar (SAR) offers day and night imaging, without impact from atmospheric conditions.
Study of the September-October 1997 Umbria-Marche earthquakes that took place in Italy. Use joint inversion of GPS and SAR interferometry data.
We present a real-time high-performance and fault-tolerant FPGA-based hardware architecture for the processing of synthetic aperture radar (SAR) images in future spaceborne system. In particular, we will discuss the integrated design approach, from top-level algorithm specifications and system requirements, design methodology, functional verification and performance validation, down to hardware design and implementation.
We are proposing to develop a miniaturized polarimetric L-band synthetic aperture radar (SAR) for repeatpass differential interferometric measurements of deformation for rapidly deforming surfaces of geophysical interest such as volcanoes or earthquakes that is to be flown on a unmanned aerial vehicle (UAV or minimally piloted vehicle (MPV).
