Equivalence Between Cameron´s Unit Disc and PoincarÉ´s Sphere for Symmetric Scattering Characterization and Classification

Scattering type classification represents a significant step toward target classification. Both the surface of Poincare´s sphere and Cameron´s unit disc have been used separately to represent symmetric scattering matrices and to define classification methods. In this letter, the equivalence of using the surface of Poincare´s sphere and Cameron´s unit disc in terms of characterization and classification of symmetric scattering types is demonstrated mathematically.
