Alternative Decompositions of the Partially Depolarizing Symmetric Kennaugh Matrix into Two Nondepolarizing Constituents

The simplest model of rain backscatterer considered as the incoherent couple of point scatterers of equal effective crossection has been described elsewhere [1]. Here, two other decompositions of the partially depolarizing Kennaugh matrix are presented: into two mutually orthogonal matrices, or matrices producing cross-and co-polarized returns when incident polarization has been chosen for minimum total received power.
