摘要: Abstract We simulate radar scattering from meter-scale boulders of ice and rock using an algorithm geometric optics. The particles are Gaussian-random-sphere with different levels irregularity. study the effect particle size, geometry, material on albedo circular polarization ratio at microwaves concentrating S-band wavelength 12.6 cm. show that increased absorption causes albedos in both states to attenuate exponentially when contribution internally scattered waves decreases. Consequently, also Semi-empirical models for derived.
