Speckle is a common phenomenon in SAR data, which has its origin in the radar image acquisition principles. In almost all applications in geosciences speckle is considered as noise. Therefore, many approaches for the reduction of speckle exist. This lessons gives insight into the origin of speckle and an overview of concepts and approaches to distinguish between speckle and relevant information content.

This is a useful introduction to SAR speckle, especially because it explains that speckle is not simply random noise but comes from the radar imaging process itself.
