This paper analyses impact of using averaging filtering on quality of SAR images. These are commonly corrupted by
multiplicative complex correlated noise (speckle) and by additive white Gaussian noise. Methods presented in this
paper: multilook algorithm and averaging filters are examined in the context of additive white Gaussian noise reduction
and computational demands. In order to obtain high cross-range resolution of SAR images Map-Drift Autofocus
algorithm is also employed
