Radar Backscatter Measurements from Simulated Sea Ice: CRRELEX'93 Results

Abstract

We performed radar backscatter measurements on artificially grown sea ice in an indoor facility at the US. Army Cold Regions Research and Engineering Laboratory (CRREL) during the 1993 winter season. The objectives of these experiments were to study various mechanisms for simulating roughness and to better understand backscatter mechanisms. These backscatter measurements were made at 13.9 GHz and for incident angles ranging from 0 deg to 55 deg with all four linear polarization combinations: VV, HH, VH, and HV. In addition to the backscatter measurements from saline ice, the return from three calibration targets were measured. These targets included a Luneburg lens, a metal sphere and a dihedral corner reflector. These measurements were made to enable us to remove the systematic error due to polarization impurity of the antenna and other systems effects.
