Abstract. The Synthetic Aperture Radar (SAR) is able to generate images of the
sea surface that can be exploited to extract geophysical information
of environmental interest. In order to enhance the operational use
of these data in the marine applications the revisit time is to be
improved. This goal can be achieved by using SAR virtual or real
constellations and/or exploiting new antenna technologies that allow
huge swath and fine resolution. Within this framework, the presence
of the Italian and German X-band SAR constellations is of special
interest while the new SAR technologies are not nowadays operated.
Although SAR images are considered to be independent of weather
conditions, this is only partially true at higher frequencies,
e.g. X-band. In fact, observations can present signature
corresponding to high intensity precipitating clouds, i.e. rain
cells. Further, ScanSAR images may be characterized by the presence
of processing artifacts, called scalloping, that corrupt image
In this paper we review these key facts that are at the basis of an
effective use of X-band SAR images for marine applications.
