Statistical properties of speckle and full polarimetric filters in SAR

Reducing the speckle effects in polarimetric data implies the use of statistical models for the speckle. A well known model is the product model which assumes the same texture variable for all the elements of the covariance matrix (CM). The authors present 2 models which allow differences between channels. For each model, a filtering technique is also presented. Finally, an analysis of texture variations is realized on several natural and non natural clutters
