“…With the advent of polarimetric SARs, new, effective, and automatic physical approaches have been conceived to locate and monitor oil spills [Gade et al, 1998;Migliaccio et al, 2011Migliaccio et al, , 2009aMigliaccio et al, , 2009bNunziata et al, 2011Nunziata et al, , 2010Nunziata et al, , 2008Velotto et al, 2011;Zhang et al, 2011]. These new approaches exploit the correlation characteristic between and among polarimetric signals when crude oil at sea is observed.…”
