Greenland Observed at High Resolution by the Seasat
The Ku-band (14.6 Ghz) Seasat scatterometer (SASS), which flew for 3 months in 1978, was designed to measure the normalized radar backscatter coeficient (60) of the Earths surfice for the purpose of estimating near-surface wind vectors over the ocean.

| Summary: | The Ku-band (14.6 Ghz) Seasat scatterometer (SASS), which flew for 3 months in 1978, was designed to measure the normalized radar backscatter coeficient (60) of the Earths surfice for the purpose of estimating near-surface wind vectors over the ocean. Even though SASS made measurements of 00 over land and ice regions, the application of this data has been limited due to the low (50 km) resolution of the measurements. A new technique for generating high resolution (5 km) images of surface radar backscatter characteristics is detailed in a companion paper [l]. The method utilizes overlap in the measurement cells from subsequent orbits over the region of interest and combines them using signal processing techniques in order to form high-resolution estimates of backscatter coefficients. In this paper we apply the reconstruction method to SASS data for the study of Greenland's ice |
