Sea Ice Detection Using GNSS-R Data From TechDemoSat-1
A new method for the detection of sea ice using GNSS-R (Global Navigation Satellite Systems Reflectometry) is presented and applied to 33 months of data from the U.K. TechDemoSat-1 mission. This method of sea ice detection shows the potential for a future GNSS-R polar mission, attaining an agreement...
