SIMULATED POLARIMETRIC SIGNATURES OF PRIMITIVE GEOMETRICAL SHAPES

Polarimetric signatures of two primitives shapes (dihedral and edge) a re simulated using high-frequency electromagnetic scattering methods. Signatures are predicted for a variety of orientations of the shapes. Polarimetric responses are analyzed using a polarization scattering ma trix decomposition developed by Cameron and Leung [1], [2]. It is show n that symmetric scatterer responses can be represented as points cont ained in the unit disc of the complex plane. The simulation shows that the polarimetric responses of the primitive shapes are remarkably sta ble as the shapes are rotated about various axes.
