Abstract:

During this period we have 1 developed a two-layer anisotropic random medium model to exploti the anisotropic effect of sea ice for active and passive microwave remote sensing, 2 used the Feynman diagrammatic technique in selectively summing and infinite perturbation series to include multiple scattering effects due to secularities that occur in the series for long-distance propagation, 3 extended the study of the two-layer anisotropic random medium model to a layer of isotropic random medium on top of a layer of anisotropic random medium in order to simulate the snow-covered ice fields for active microwave remote sensing, 4 used the strong fluctuation theory and the fluctuation-dissipation theorem to calculate the brightness temperature from a bounded layer of random discrete scatters with the zeroth and first order approximations, and 5 participated in the microwave sea ice measurement program at the Cold Regions Research and Engineering Laborataory CRREL in New Hampshire.
