The components of the polarimetrictarget decomposition reflect the differences of target since they linked with the scattering properties of the target and can be imported into SVM as the classification features. The result of decomposition usually concentrate on part of the com-ponents. Selecting a combination of componentscan reduce the features that importing into the SVM. The features reduction can lead to less calculation and targeted classification of one target when we classify a multi-class area. In this research, we import different combina-tionsof features into the SVM and find a better combination for classification with a data of AGRISAR.
