Ultra-wideband radar measurements of snow thickness over sea ice

An ultra-wideband, frequency modulated, continuous wave radar working from 2.0 to 6.5 GHz was designed, built and tested at the Center for Remote Sensing of Ice Sheets (CReSIS) at the University of Kansas to measure snow thickness over sea ice. Improvements and modifications to the existing radar, compared to previous versions, allow for snow thickness measurements from fast-moving, long-range aircraft. Over the past year, the radar has recorded snow thickness measurements over sea ice in the Arctic and Antarctic oceans as part of NASA's Operation Ice Bridge.
