Ice-sheet sounding at X, L and UHF bands from high altitude by vertical SAR imaging
International audience Though generally used for side-looking "push-broom" imaging, the synthetic aperture radar principle can, as well, be applied to nadir looking vertical plane imaging. Vertical SAR has proven useful e.g. for high altitude altimetric accurate navigation resetting. Durin...
