INTERPRETATION OF POLARISATION BEHAVIOUR OF RADAR WAVES TRANSMITTED THROUGH ANTARCTIC ICE SHELVES.
We have collected polarimetric ice sounding radar data on Brunt, George VI and Ronne ice shelves using a vector network analyser as a continuous wave step-frequency radar. Being a wideband phase sensitive instrument, the radar allowed the vectorial nature of the interaction between radio waves and t...
