Ultra-Wideband Radar Measurements over Bare, Snow-Covered and Pancake Ice

摘要

An ultra-wideband radar and a plane wave antenna have been used to measure thehigh resolution scattering response of bare saline ice, snow covered ice and pancake ice during the winter seasons of 1994 and 1995 at the US Army Cold Regions Research and Engineering Laboratory (CRREL). The objectives of these experiments were to study various mechanisms for simulating roughness and to understand scattering mechanisms better. These backscatter measurements were made at 2-18 GHz and 0.5-16.5 GHz during the 1994 and 1995 experiments respectively, and were made for incidence angles ranging from 0 to 55 deg. These broadband measurements provide a vigorous test for models at many frequencies using a single system instead of many single frequency systems.
