Man-made marine litter constitutes nowadays a major environmental threat. Most of current studies address optical detection techniques, but these have impairments related to lighting conditions, cloud cover and biofouling.
Microwave techniques (MW) do not suffer from the previous limitations, therefore, they are a potential resource for detection of marine floating litter. However, to date, there is no systematic characterization of the MW signature of floating plastic.
The objective of the project is to characterize the MW response of floating macroplastic, to find the most favorable MW sensing modality, best frequency bands and, for each one, find the minimum required concentration of the litter and size of the patch for positive detection.
The study will consider known active radar imaging and non-imaging techniques as well as passive radiometric techniques. It will include the development or extension of known data processing and analysis methods to favor the detection of plastic litter.
