Abstract:
Modern radars for radio-echo sounding of ice sheets carry multiple receive channels in cross-track, allowing for clutter suppression, as well as for synthetic aperture radar tomography of the ice sheet and bed. Tomographic processing provides 3-D information about the sub-surface topography, bed conditions and internal layers’ orientation. We explore synthetic aperture radar tomography based on sparse signal reconstruction, offer a particular algorithm implementation and demonstrate its performance using data acquired by the Multichannel Coherent Radar Depth Sounder of the Center for Remote Control of Ice Sheets during the 2008 campaign in Greenland.
