| Resumo | The applicability of L-band Synthetic Aperture Radar (SAR) to identify and extract information from oil spills in marine environments has been studied. Although the extraction of this type of information is possible, is necessary to analyze the backscatter signal from the targets of interest, i.e., water and oil. This study aims to make a preliminary analysis of the adequacy of data collected by the Phased Array Lband SAR (PALSAR) sensor, on board the Advanced Land Observing Satellite (ALOS), to discriminate oil films yielded by seepages or spills in offshore environments of the Gulf of Mexico. The results show that the HH and VV polarizations have a signal decreasing trend when the incidence angle increases. This trend is clearly observed for incidence angles above 25o , which is related to the tilted Bragg scatter mode. Furthermore, were verified that the HH and VV polarizations acquired on PLR acquisition mode and HH acquired on FBD acquisition mode are suitable to discriminate oil spills films from oceanic water. The opposite was verified about HV polarization in both acquisition modes.
