Conclusions 
The Rayleigh speckle model, whose validity has been widely demonstrated 
in the past, can be extented in the context of Synthetic Aperture Radar 
imaging. The harmful speckle effect can be useful if the complex signal, rather 
then the detected signal, is considered. The results described here show the 
applications of this model to the estimation of the parameters of SAR sensors 
and to the evaluation of the quality of the processed image.
