Abstract:
Coherent polarized waves, propagating toward and receding from an observer, together with their representation in terms of orthogonal linearly and circularly polarized component pairs are described in some detail. Appropriate matrix formulation facilitates their bases interchange and enables a better understanding of their characteristics, especially in connection with radar or communications related subjects. Component parameters in terms of Poincarphere locations are described and readily characterize measurable relationships among different polarizations. Polarization distortion effects using phased array apertures with dual polarized elements are emphasized and details concerning signal bit resolution and phase center coincidence effects are described and analyzed. An approach to polarization filtering is reviewed and the well known polarization related parameter characterizations, the Ludwig-3 cross-polarized component definition and the Huynen Fork representation of radar target parameters, are described and relevant analyses presented. An illustrative polarization related problem concerning ground-based systems and SATCOM interaction illustrates many of the parameter design considerations described within the report. Throughout the text, numerous derived parametric plots are illustrated which aid in an overall understanding of the major details of this important subject
