【Abstract】 The first and second order iterative solutions of the scalar radiative transfer equation for a layer of random non spherical particles are derived. An iterative inverse method of the Legendre coefficients of the phase function with the relationship of small spheroids is developed. Using two measurements of azimuthal distribution of bistatic scattering, the dielectric constant of a layer of random small spheroids and the number of particles per unit area are iteratively inverted. This approach is more feasible than some available methods, and is applicable to retrievals of dielectric and nonfigurative parameters of particulate materials and terrain surfaces.更多还原
