Abstract

Exact and approximate methods are developed to determine radar antenna polarizations that maximize power contrast between two scatterers. Antenna polarizations to maximize received power are also obtained. These polarizations will maximize target-noise ratio and the ratio of target power to power from unpolarized clutter. Matrices that represent unpolarized clutter are given. It is shown that a backscattering covariance matrix to represent unpolarized clutter for any incident wave does not exist. Target matrices used are the bistatic and backscattering covariance matrices, the Kennaugh matrix, and the Graves power scattering matrix.
