In this paper we outline a new approach to the analysis of polarimetric synthetic aperture (POLSAR) data. Here we exploit target orthogonality as a multi-dimensional extension of wave orthogonality, familiar on the Poincar\'e sphere. We first show how to formulate a general basis for a complex orthogonal scattering space using a generalization of the Poincar\'e formulation, and then show how to optimize the backscattered signal in this space for both monostatic and bistatic radar systems. We
