The polarization phasor approach has been applied to the theory of radar polarimetry. It is based on introduction of two mutually conjugate 2-dim. complex spaces of the polarization and phase PP vectors and on application of the matrix calculus to the transmission equations when using the exactly defined PP bases. The PP vectors of waves and antennas, including their PP basis vectors, are considered as phasors tangent to the polarization sphere. Owing to that approach simple canonical forms of bistatic scattering matrices and their Poincare sphere geometrical models have been obtained. It has been shown how such models, demonstrating the way of polarization and phase transformation when scattering, may be useful in various practical applications like target recognition and classification by extraction from scattering matrices parameters independent of the polarization basis. They enable also polarimetric analysis of microwave networks and can be used to synthesize scattering or propagation matrices of desired polarimetric properties.
