Controllability Analysis of Polarization Characteristics of Scattering Elements for Reproduction Application

Polarization characteristic is an important characteristic of radar target. Based on the electromagnetic modeling and calculation of foreign typical moving platform, the typical polarization characteristics of the coexistence of in-phase and orthogonal component in the return are obtained. And then combined with scattering matrix theory, it is proposed that the conventional generic scattering elements cannot reproduce the two components at the same time, and the necessity of the research on controllable polarization characteristics of scattering elements is demonstrated.
