Based on the multiplication speckle model, the statistical characteristics of the polarimetric signatures are analyzed, which include co-polar and cross-polar ratios and co-polar phase difference for multi-look polarimetric SAR data. With the simulated data, the effect of the estimated accuracy of the polarimetric signatures on the performance of the algorithm for suppressing the speckle is analyzed.
