It is well known that Synthetic Aperture Radar (SAR) images are degraded by speckle noise. Multilook processing is the traditional and popular technique to reduce it. Usually, multilook is implemented in one dimension, i.e., with reference to the azimuthal spectrum of SAR data. In this paper we extend multilook techniques to two-dimensional SAR spectra. Two different designs of parallel architectures for multilook implementation are presented and discussed.
