ABSTRACT
Remote sensing plays a key role in many domains devoted to observation of the Earth, such as oceanography, cartography, or agriculture monitoring. Among the different acquisition systems, Synthetic Aperture Radar (SAR) imagery has broadly opened the field of applications in the past 20 years. This active sensor emits a microwave illumination (1-10 GHz) and measures the backscattered component (see Refs. 1 and 2 for a detailed description of the system). It offers the advantage of acquiring high-resolution images of the Earth’s surface, in any weather conditions, both day and night. However, the main drawback of SAR is the well-known speckle corruption, inherent to any active and coherent imaging technique, which limits the analysis of the image.
