HD-6: SAR oil spill observation
Sunday Afternoon, July 6, 13:30 - 17:30
Presented by
Maurizio Migliaccio, Università di Napoli Parthenope
Abstract
Sea oil spill is matter of great concern since affects the life cycle and the human food chain. Remote sensing can be of great help since it provides data at relatively low cost and a continuous and synoptical sea observation. The active microwave Synthetic Aperture Radar (SAR) is the key sensor because of its high spatial resolution and its practical insensitivity to cloud cover and other atmospheric phenomena.
In simple terms, SAR oil spill observation is possible since oil damps the short gravity and capillary waves which mainly contributes to the electromagnetic backscattering and a low scattering area is generated. Unfortunately, other physical phenomena, known as look-alikes, generate low scattering areas over SAR images.
A state-of-art of the SAR procedure will be sketched as well as a new physical approach which is framed within the mathematical one-class problem. It will be showed that it is possible to exploit full-resolution SAR images once that proper speckle modelling is taken into account. In fact, it is shown the physical significance of the three GK distribution parameters, as descriptors of marine dark areas and strong (although small) scatterers over Single-Look Complex (SLC) SAR images. The usefulness of full polarimetric SAR will be illustrated in terms of enhanced detection capability and in terms of assisting low scattering area classification. A new dual-polarized approach will be also illustrated.
Finally, the new trends in electromagnetic modelling for SAR oil spill observation will be traced as well as their integration into an operational system.
