Interpretation of Seasat radar altimeter returns from an overflightof ice in the Beaufort Sea

摘要

Seasat radar altimeter data are examined for the effects of seaice on the returns during an overflight of the Beaufort Sea. Waveformparameters and their statistics are combined to form a parametersensitive to the presence of sea ice. Variations in the value of thisice parameter are compared with ice charts obtained from the CanadianAtmospheric Environment Service. Particular attention is paid to thesensitivity of the radar altimeter to the open-ocean sea ice boundary
