Interferometric discrimination of cross-track bed clutter in ice-penetrating radar sounding data

Kirk M. Scanlan, Anja Rutishauser, Duncan A. Young, Donald D. Blankenship
2020 Annals of Glaciology  
For the surface interface, interferometry and a family of methods relying on digital elevation models have been used to successfully discriminate cross-track surface clutter.  ...  The interpretations of relevant interfaces (i.e. the surface and bed) in radar sounding datasets over glaciers and ice sheets are primary boundary conditions in a variety of climate studies and particularly  ...  We also thank the Polar Continental Shelf Program, Kenn Borek Air Ltd. and the field team for their excellent support, and NRI and the peoples of Grise Fjord and Resolute Bay for permission to conduct  ...

Radar mapping of Isunnguata Sermia, Greenland

K. Jezek, X. Wu, J. Paden, C. Leuschen
2013 Journal of Glaciology  
Ice thickness estimates using advanced nadir sounding and tomographic radar processing techniques are compared and combined in a study of Isunnguata Sermia glacier, Greenland.  ...  Analysis shows that tomographic data better capture short wavelength (1–2 km) patterns in basal terrain, but interpolated nadir sounding data yield more spatially extensive and continuous coverage across  ...  The University of Kansas also received support from the US National Science Foundation through the Center for Remote Sensing of Ice Sheets.  ...

Solving for ambiguities in radar geophysical exploration of planetary bodies by mimicking bats echolocation

Leonardo Carrer, Lorenzo Bruzzone
2017 Nature Communications  
Here we propose an adaptation of the unique bat clutter discrimination capability to radar sounding by devising a novel clutter detection model.  ...  Sounders are spaceborne radars which are widely employed for geophysical exploration of celestial bodies around the solar system.  ...  We argue that it is possible to adapt the bat clutter mitigation technique to the radar sounding case.  ...

Permanent Scatterers in Repeat-Pass Airborne VHF Radar Sounder for Layer-Velocity Estimation

Davide Castelletti, Dustin M. Schroeder, Thomas M. Jordan, Duncan Young
2020 IEEE Geoscience and Remote Sensing Letters  
When merged with the horizontal surface velocity and the numerical models, layer velocity can support the 3-D analysis of the ice flow and structure.  ...  Then, we compute the interferometric phase for the englacial layers (which are shown to behave as PSs in the nadir sounding geometry), to estimate a vertical displacement and a velocity profile.  ...  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.  ...
