Abstract

This contribution is concerned with the mathematical formulation and theoretical background of the discs in the context of Radar Polarimetry. We consider strict radar backscattering, the monostatic case, character-ised by the random Sinclair matrix S(t) in a common linear basis. Using the target feature vectors leads to the Hermitian positive semidefinite Covariance matrices, where the eigenvalues are obtained by unitarily diagonali-zation. A special region G(A), called the discs and the associated boundaries denoted by circles is considered to be of possible value in revealing information about the eigenvalues of a given Covariance matrices. We arrive at particular classes of easily computed regions in the plane that are guaranteed to include the eigenvalues of a given covariance matrix.
