%X In this paper, the statistics of the union Stokes parameters in Gaussian assumption is derived from the Whishart distribution, and through the polarization invariant the analytic expressions of the four Stokes parameters are presented. The results have a comparison with the conclusion derived before, which shows the presented expressions to be simple and exact. Then the statistical PDF(Probability Density Function) of the normalized Stokes parameters are showed ,which describes the variety of the polarization state in another way. All the above can be useful to speckle reduced, classification for terrain and target recognition in complex environments or other applications.
