E ARTH OBSERVATION (EO) via satellite sensors toimage the Earth, day and night and in almost all weatherconditions at high-spatial resolution, attracted the scientific andindustrial interests in 1950s of the last century [1]. Syntheticaperture radar (SAR) technology advanced in classified andnonclassified formats leading, in the late 1960s, to the wellknownGoodyear SAR system [1].From its early stage, it was clear that SAR was an importanttool to help monitoring Earth environment [2], [3]. A SARis an active microwave high-spatial resolution imaging sensoracting as a microwave transducer of the electromagnetic fieldscattered by the scene. In other terms, a SAR is a filter thatestimates the scene backscattering. Therefore, a SAR imageis not a simple and straightforward representation of thegeophysical quantity of interest, and the interpretation stepcalls for a physical modeling and inverse problem to be dealtwith
