Scattering phenomenology of arctic lake ice

摘要

This paper presents the radar scattering phenomenology of arctic shallow lake ice. This is an important feature for monitoring the arctic climate for this purpose, a full-wave simulation model to analyze lake ice scattering that includes columnar air bubbles and rough interface is presented. The proposed model can handle complex interactions between high density air bubbles and rough ice surfaces. Based on this model, the scattering contributions from the rough ice/water interface and columnar air bubbles in the ice at C band are calculated. It is concluded that the roughness at the interface between ice and water is the dominate contributor to the observed backscatter.
