Radar backscatter from sea ice ridges modeled as rough and layered media

Although sea ice ridges are stronger than level ice and are responsible for significant ice volume in the Arctic, they are generally not represented on the ice charts produced by national ice centres. Tools such as ground penetrating radar can be used to measure ice thickness and indicate ice strength. The research involves deriving the equations that describe how electromagnetic waves interact with sea ice ridges, which have been modeled as rough, layered media. Preliminary sea ice models have been generated and simulations of the backscatter from stratified media have been prepared. A model describing the backscatter from a one-dimensional rough surface has been generalized to be applicable for sea ice and initial results are presented.
