On the polarization response using resonances for target recognition

In most studies concerning resonance based target recognition, targets are usually excited and measured using a linear polarized basis and at the same time ignoring the cross polarization component. In this paper, the possibility of using circular polarization in this context is investigated. Numerical results of some simple wire targets demonstrate that it would be easier to fully excite all of the important resonances using a circular polarization basis with due consideration of the co- and cross-polarized directions.
