Develops and analyzes two parametric models in which electromagnetic plane waves carrying polarimetric information are received. The first model considers estimation of the polarimetric response of a surface by measuring the reflections of actively generated waves. The second considers estimation of the polarization of passively generated waves. Both models have applications to remote sensing. The authors propose a natural parametrization of the distribution of the received signal. Using the Cramer-Rao bound, they characterize the best possible accuracy of unbiased estimators of these parameters. Simple estimators are given. Both models are fitted into a common framework and compared
