Application of Synthetic Aperture Radar (SAR) Imagery on Antarctic Glaciology
Antarctic sea ice and ice sheet were studied using the ERS-1 and JERS-1 SAR images received at Syowa Station in 1991-1993. Analysis was mainly done for sea ice in Lutzow-Holm Bay, ice streams flowing into the bay, ice sheet near the coast and inland nunataks. Back scattering coefficient of the SAR i...
