| Résumé | This paper discusses the physical properties of naturally grown first-year sea ice and the implications that ice physical properties have for single- and multi-polarization SAR images. Temporally and spatially coincident images from the vertically polarized European Research Satellite (ERS-1) and the CCRS polarimetric airSAR are compared. Quantified from the two different SARs is the backscattering coefficient of three sample areas of first-year ice near Resolute, Cornwallis Island. The 46° to 52° span of incidence angles in the polarimetric airSAR produce much lower microwave returns than observed from the 23° incidence angle of the ERS-1 satellite. The direct influence that ice salinity, density and microstructure have upon the ice microwave scattering characteristics is quantified in terms of the backscattering coefficient. |
