In contrast to the ground-based sensors, the airborne radar sounder data can potentially be used to estimate the layer velocity on a continental scale.  ...  Our aim is to provide the proof-of-concept demonstration that, similar to the sidelooking synthetic aperture radar for imaging, the airborne radar sounder data can be used to estimate the subwavelength  ...  ACKNOWLEDGMENT The authors would like to thank the University of Texas Institute for Geophysics (UTIG) for providing the example data with which this technique was developed and demonstrated.  ...

By detecting the transitions where the ice starts to move vertically in response to the tidal forcing we determine control points for the grounding line position along GPS profiles.  ...  Accurately knowing its position is fundamental for both modelling the glacier dynamics and establishing a benchmark for later change detection.  ...  Constructive comments and suggestions from two anonymous reviewers have been very helpful in improving this paper.

Interferometric Synthetic Aperture Sonar Design and Performance [article]

Philip John Barclay, University Of Canterbury
<span title="2008-09-07">2008</span>
The InSAS approach is similar to the radar equivalent (InSAR), however, significant differences in geometry and medium properties limit the applicability of InSAR algorithms to the sonar equivalent.  ...  Therefore, for an accurate estimate of the time-delay, the signals of the receivers must contain significant 'common' information.  ...  Volumetric scattering violates the assumption of a single scatterer position within each resolution cell. Repeat-pass interferometry.  ...
