		<abstract>The main purpose of this work is to study and implement the Maximum a Posteriori(MAP) filter to supress speckle in SAR images. This type of noise is due to the coherent nature of the radiation used in Synthetic Aperture Radar and the interference between the waves reflected from the imaged area. This paper is based on on the multiplicative model and considers several different densities to describe the "a priori" knowledge.</abstract>
