Redevelopment of Kennaugh's target characteristic polarization state theory using the polarization transformation ration formalism for the coherent case

The Kennaugh target characteristic polarization theory for the monostatic reciprocal coherent case is developed in greater detail. Emphasis is on the transformation of the scattering matrix under the change of polarization basis via the unitary transformation matrix formulated in terms of the polarization ratio rho . Six characteristic polarization state are determined, and displayed on the Poincare sphere and on power and phase plots. Several simple target cases for demonstrating the applicability of this useful concept to radar target classification, imaging, and identification are considered.<
