The Normalized Radar Cross Section in SAR images depends on the incidence angle, on the wind intensity as well as on the angle between the radar beam and the wind direction; at incidence angles < 20° the specular reflection is prevailing while at greater angles Bragg mechanism predominates. A surface slick damps short waves and its presence is revealed by dark spots on the image; the detectability...
A novel approach to land masking in synthetic aperture radar (SAR) images is designed and implemented. The developed algorithm takes as input an archived shoreline from a public domain database and modifies it to draw the actual shoreline on SAR images by analysing backscatter values. Starting with data from the GSHHS (the global self-consistent hierarchical high-resolution shoreline database), coastline...
Satellite-borne SAR is used for sea surface observation and extraction of meteo-marine features as well as detection of oil slicks. In this paper we want to describe the activity based on the detection algorithm we developed in previous activities, able to identify oil spills in an automatic routinely way, as well as to evaluate detection reliability with a percentage value. Starting from that previous...
