A radar backscattering model of sea foam and spray is considered The model suggested is based on a modified Mie theory describing resonance scattering and adsorption effects from polydisperse systems of air bubbles (foam) and water droplets (spray) in a wide range of microwave frequencies. Joint contributions of foam and spray in the backscattering coefficient are investigated as well. As a result of our modeling, it is shown that the backscattering coefficient depends on microstructure…

The authors' computations indicate specific variations and oscillations of the backscattering coefficient that can be used for evaluations of foam and whitecap backscatter signatures in the radar images.

Microwave emission and scattering of foam based on Monte Carlo simulations of dense media

The foam-covered ocean surface is treated as densely packed air bubbles coated with thin layers of seawater and Monte Carlo simulations of solutions of Maxwell's equations are applied to calculate the absorption, scattering, and extinction coefficients that are used in dense-media radiative transfer theory to calculated the microwave emissivity.

Remote sensors operating at electromagnetic wavelengths cannot significantly penetrate ocean water but are effective at observing surface phenomena (such as waves and winds). Radar remote sensing can
