摘要: Speckle noise is a critical disturbance in the Synthetic Aperture Radar (SAR) image that alters its quality. Initially, speckle SAR images should be reduced when recognizing and detecting automatic targets. This paper presents performance analysis of different filters which are applied images. The individual to achieve suppression ability preserve edges details analyzed. some morphological explored. Some these result small losses information on It has also been found region homogeneous area tends increase with respect filter window size. provide good preserving an while suppressing compared other adaptive filters. Finally, recent challenges reduction
