Abstract
During the 19th century, the theory of electromagnetic fields became a firmly established science: Maxwell's equations accurately described the propagation of the fields,Marconi'swireless experiments demonstrated the possibility of wireless communication at large distances. Nevertheless, even since that early time it was evident that electromagnetic waves could be not only used for communication but also to obtain information, or better to "sense" the environment and the objectswithout being in contactwith them. Remote sensing is today well established and intensively used for acquiring information about the Earth's surface [120]: among the most used remote sensing systems, active microwave sensors and particularly Synthetic Aperture Radar (SAR) have gained an increasing interest from both a scientific and industrial viewpoint. This success is a consequence of the capability of the sensor to operate independently of an external illumination source (day and night) and practically in almost any meteorological condition.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
