Polarimetric simulations of bistatic scattering from ocean surfaces at L band

In this study we simulate the fully polarimetric bistatic scattering behavior resulted from the interaction of electromagnetic wave with all scales of ocean waves, with a focus on the dependence of such behavior on wind direction and incidence angle. The numerical approach is our recently developed second stochastic degree iterative algorithm with sparse matrix and Chebyshev approximation. The illuminated area is 86 wavelength × 86 wavelength, which represents about 2.5 dominant wavelengths for a 3m/s Elfouhaily spectrum at L band, implying that the effect of gravity wave has been adequately included. The total number of surface unknowns is 2,130,048. Numerical results for both angular backscattering behavior and bistatic patterns are provided.
