Preserving Polarimetric Scattering Characteristics Classification by Introducing Normalized Circular-pol Correlation Coefficient

Buildings being not orthogonal to the light of sight of SAR are often marked as volume scattering in the three-component decomposition.A new unsupervised classification algorithm is proposed by introducing normalized circular-pol correlation coefficient,which can improve the discernment of non-reflection symmetric structure on the basis of three-component decomposition.The experiment using E-SAR L band PolSAR image around DLR proves the effectiveness of the proposed method.
