Stable Decomposition of Mueller Matrix

概要

Huynen has provided a method to decompose a Mueller matrix into an average single target and a N-target (non-symmetric target and noises) in order to retrieve detailed target information. However, the decomposition sometimes fails in the presence of small error or noise in the elements of Mueller matrix. This paper attempts to improve Huynen's decomposition method. First, the definition of a stable decomposition is given, showing the importance and a problem of Huynen's approach by an example. Then a method is proposed to carry out stable decomposition, based on the Least Squares Method and the Newton's Method. Stability means the decomposition is not sensitive to errors. The proposed methods overcomes the problems on the unstable decomposition of Mueller matrix. Finally, two numerical examples are given, showing our method is superior to the methods of Huynen and Pottier.
