The Role of the Surface Waves in Forming the Propagation Pattern of EM Signals over the Ocean and Wavy Boundary Layer Measurements during RED

Abstract

The long term goal of this research is to bring better understanding of how atmospheric conditions and sea state affect the propagation pattern of EM signals over the ocean. Scattering from layered structure of the atmosphere (Wait, (1970)), random fluctuations of the refractive index as well from the rough ocean surface, are intricately involved in the pattern formation, although their interaction and quantitative contribution is incompletely understood. A particular focus of this work is to reveal the role of the atmospheric pressure fluctuations (Bean and Dutton, (1968), Ishimaru, (1978)), both turbulent and wave-induced, in the variability of the refractive index, as well as to enhance our understanding of the EM scattering properties of the ocean surface as a function of the sea state.
