摘要：

During the March 1987 Labrador Ice Margin Experiment (LIMEX '87) two independent investigations were conducted to determine the C-band backscattering cross section of the marginal pack ice along the Newfoundland coast. In one experiment, data from a recently calibrated C-band airborne scatterometer were combined with C-band synthetic aperture radar (SAR) data to measure the normalized scattering cross section of the ice from 10-degrees to 74-degrees incidence angle to within +/- 2 dB. In the other experiment, detailed measurements of ice surface roughness and surface properties were made and the radar cross sections were predicted from a scattering model. This paper combines measured and model results and shows them to be fully compatible. By extension, this study is expected to apply to any rubbled sea-ice surface when surface scattering dominates.
