Summary:Parametric scattering center models match to radar scene attributes, aiding in automatic target recognition (ATR) and scene visualization. In this paper, we develop parametric models of canonical shapes for bistatic synthetic aperture radar (SAR).We generalize geometric theory of diffraction solutions for scattering mechanisms in a plane to develop three-dimensional models for six canonical shapes: a rectangular plate, dihedral, trihedral, cylinder, top-hat, and sphere. The proposed models provide physically relevant yet compact scattering solutions that are easily implemented for radar signal processing and ATR applications. The derived models are shown to agree with results obtained from high-frequency, asymptotic scattering simulations.
