Sea ice and snow
thickness retrieval using correlation function in VHF radar
Back to Research Main
Summary
In this project, we
develop models for electromagnetic wave propagation through multi-layer
sea ice media. Based on the models, we calculate the angular and
frequency correlation function (ACF/FCF) of the backscattered waves at
the desired frequencies and angles. The characteristics of the ACF/FCF
are investigated, leading to the retrieval of sea ice thickness and
snow-cover characteristics. We develop a model for VHF which will be
used to investigate sea ice and we study a model for higher frequency
(C, Ku, K band) that can be applied to snow-cover characteristics. We
also perform proof-of-concept experiment on retrieval of material
thickness based on this ACF/FCF method.
