2019 Remote Sensing  
Spaceborne radar altimeters record echo waveforms over all Earth surfaces, but their interpretation and quantitative exploitation over the Arctic Ocean is particularly challenging.  ...  Radar returns may be from all ocean, all sea ice, or a mixture of the two, so the first task is the determination of which surface and then an interpretation of the signal to give range.  ...  Introduction Within the Arctic Ocean, radar altimetry is used to monitor both the sea level and the freeboard of sea ice, i.e., how far the ice surface is above the surrounding water level.  ...
