A REVIEW OF TARGET DECOMPOSITION-THEOREMS IN RADAR POLARIMETRY

In this paper, we provide a review of the different approaches used fo r target decomposition theory in radar polarimetry. We classify three main types of theorem: those based on the Mueller matrix and Stokes ve ctor, those using an eigenvector analysis of the covariance or coheren cy matrix, and those employing coherent decomposition of the scatterin g matrix. We unify the formulation of these different approaches using transformation theory and an eigenvector analysis, We show how specia l forms of these decompositions apply for the important case of backsc atter from terrain with generic symmetries.
