摘要：

This paper discusses development of physics-based models for bistatic scattering. We generalize parametric equations for monostatic scattering mechanisms in a plane to achieve analogous bistatic approximations. Combination of these mechanisms, as separable azimuth and elevation components, allows 3-D modelling of six scattering primitives: sphere, tophat, trihedral, dihedral, cylinder, and flat plate. The responses of these scattering center models are shown to compare favorably with results obtained from validated high-frequency simulations.
