Sparse SAR Tomography of Ice Sheet and Bed

Modern radar ice sounders carry multiple receive channels allowing for across-track clutter suppression as well as for 3-D SAR tomography of ice sheet and bed, which in its turn provides information about the scene topography, bed conditions and internal layer orientation. We explore SAR tomography based on sparse signal reconstruction, offer a particular algorithm implementation and demonstrate its performance using a dataset acquired by Center of Remote Control of Ice Sheets during 2007 campaign in Greenland
