Ku band airborne radar altimeter observations of marginal sea ice during the 1984 Marginal Ice Zone Experiment
Pulse-limited, airborne radar data taken in June and July 1984 with a 13.8-GHz altimeter over the Fram Strait marginal ice zone are analyzed with the aid of large-format aerial photography, airborne synthetic aperture radar data, and surface observations. Variations in the radar return pulse wavefor...
