Study of out of plane bistatic scattering from rough dielectric surfaces

The paper examines the like- and cross-polarised bistatic scattering characteristics from random rough surfaces along the azimuth angle. To compare the contributions of single and multiple scattering, it studies the effect of multiple scattering under different surface parameters. The single cross-polarised scattering coefficient vanishes in the plane of incidence, but the single like-polarisations reach their minima near 90° from the incident plane. The multiple scattering therefore shows the significant contribution to the cross-polarised scattering in the plane of incidence and the like-polarisations in the orthogonal plane. The model is evaluated by comparing the prediction with the measurement and demonstrates good agreement between the prediction and the experimental data for both like- and cross-polarised scattering coefficients
