Interferometric discrimination of cross-track bed clutter in ice-penetrating radar sounding data
2020
Annals of Glaciology
Preserved Fulltext
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 ...

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 ...

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. ...
