The presence of speckle noise in Synthetic Aperture Radar images prevents a correct interpretation, as well as, the information retrieval processes. It has been recently demonstrated that speckle noise may introduce biases into the retrieved physical information when multidimensional data is considered. In case of multidimensional SAR systems, for single-look data, it has been proved that speckle noise is due to the combination of multiplicative and additive noise sources. This paper details the extension of this noise model to multilook, multidimensional SAR data.
