Abstract :
The theory of eigenvalues is developed for the asymmetric scattering matrix. The basic properties of eigenvalues are studied. A method is proposed for finding the eigenvalues of such a matrix. It can be proved that the maximum of the magnitude of the eigenvalue is smaller than the maximum of the singular value for the asymmetric scattering matrix. It is shown that the matrix can be diagonalized in two different ways. It is shown that E.M. Kennaugh´s (1952) optimal polarization will involve the singular value problem of the asymmetric scattering matrix. On the basis of the spectral theory of matrices, Kennaugh´s optimal polarization for radar reflection can be found easily.<>
