It is a 200-400 MHz FMCW radar, with a 1-second chirp, run by controller. Each radar was set to produce a burst of 50 chirps every 4 hrs, and a config file with radar settings is provided with each dataset. \nFiles:\n*.dat - binary files containing raw data\nconfig.ini - config file containing all radar settings used for each site\nSoftware for processing the raw data can be obtained from Dr. Keith Nicholls, British Antarctic Survey.
