Abstract :
A series of ENVISAT AP mode data has been collected over the Nome field off the coast of central Norway. An oil production vessel has been imaged with different ASAR beams and polarisations to study how its signature changes with varying imaging parameters. Cross-polarised data gives better contrast for automated detection compared to co-polarised data, when the incidence angle is small.
