Multi-look polar decomposition of polarimetric SAR images

This paper focuses on the multi-look polar decomposition. of SAR images Standard polar decomposition is generally used in single kick polarimetry to decompose a bi-static or mono-static polarimetric scattering matrix into, a product of an hermitian matrix (boost) and a unitary matrix (rotation). An extension of this use in the framework of multi-looked polarimetry is proposed here. This now approach consists in decomposing the scattering matrix into bout and rotation components before vectorisation, then in averaging to generate boost and rotation coherency matrices separately, with now inferred parameters: the bond and rotation entropies, and concurrent dominant scattering mechanism (alpha boost and alpha rotation) This multi-look extension of polar decomposition may allow for the definition of a now classification. strategy for remote sensing data.
