The purpose of the research reported here was to determine the sources of scattering of artificial sea ice, to compare backscatter measurements semi-quantitatively with theoretical predictions, and to develop inexpensive polarimetric radars sea ice backscatter studies. A brief review of the dielectric properties of sea ice and of commonly used surface and volume scattering theories is presented. We provide a description of the backscatter measurements performed and experimental techniques used. Discussion of the development of inexpensive short-range polarimetric radars is the topic of chapter 4. In Chapter 5, we discuss ice surface characterization data and techniques, including computation of surface rms height and correlation length and air bubble distribution statistics. Chapter 6 consists of comparison of backscatter measurements and theory. Keywords: Military publications, Periodicals.
