Radar Backscatter Measurements from Simulated Sea Ice During CRRELEX '90
Radar backscatter measurements were performed on artificially grown sea ice on an outdoor pond at the US. Army Cold Regions Research and Engineering Laboratory (CRREL) during the 1990 winter season. Measurements of microwave backscatter from simulated sea ice demonstrate that the dominant backscatte...
