This paper is focused on considering the effects of
speckle noise on the eigen decomposition of the co-
herency matrix. Based on a perturbation analysis of the
matrix, it is possible to obtain an analytical expression for
the mean value of the eigenvalues and the eigenvectors,
as well as for the Entropy, the Anisotroopy and the dif-
ferent a angles. The analytical expressions are compared
against simulated polarimetric SAR data, demonstrating
the correctness of the different expressions.
