Abstract :
In this paper we introduce two new parameters for polarimetric SAR (POLSAR) images. For this purpose, the eigenvalues and corresponding eigenvectors of the coherence matrix is calculated. It can be assumed that there are different land cover features, and they are represented by different or slightly different coherence matrix so that eigenvalues and corresponding eigenvectors. However, the condition number and perturbation in the solution of the coherence matrix are calculated for each pixel in the POLSAR image. The results indicate that different scatterer properties so that the scattering mechanisms could be represented with these parameters.
