When the polarimetric scattering behavior is studied,a lot of SAR polarimetric data,which are received under different azimuthal look angle,are employed,but the variation of polarimetric scattering behavior are not taken into accout generally.

The definition of EM polarization scattering matrix for cylinder;

A new valuable definition of EM polarization scattering matrix S s for cylinder,which has six freedoms and includes all information of the scattering wave of cylindrical scatterer,is presented.

As temperature increased, the carrier scattering mechanism shifted gradually from ionized impurity scattering to acoustic p.

To overcome this shortcoming,a novel scheme based on scattering mechanism identification and azimuthal symmetry decision is proposed in this paper.

The direct relation among coherent matrix eigenvalue,eigenvalue index of polarimetric synthetic apert-ure radar(SAR) images and scattering amplitude function is derivated in this paper,and then the canopy model of polarimetric scattering is used to discuss the relation in eigenvalue index and degree of canopy sparseness.
