A new tomographic ice sounding method is introduced to provide airborne swath measurements of ice sheet thickness and basal scattering properties. Two major challenges have been solved: left-right signal separation and surface clutter rejection. The new technique was demonstrated using data we collected in 2006 and 2008 from a VHF-band, multiple phase-center radar system flown in Greenland. For the first time we were able to "see" radar images of the base of the ice sheet.
