The polar decomposition of the scattering matrix applied to the polarimetric image of the guard-rail

The concept of scattering is one of the mechanisms that polarimetry seeks to express through data. A multiplicative decomposition of the scattering matrix is developed and it is applied to the polarimetric image of a guard-rail. The image contains just one scattering center and so it results are particularly suitable to investigate the information that the polarimetric property of an object can deliver.
