SummaryThe objectives of this project are to investigate physical scattering from various target surfaces as function of incidence angle,polarisation, and frequency. The information will subsequently devise development of new algorithms, which can give potentially better satellite products. The data analysis methods include analysis of radiometric scattering properties, polarimetric feature extraction (e.g. decompositions), and statistical texture analysis using non-Gaussian models. The research team will conduct field campaigns with co-located in-situ measurements and satellite SAR acquisitions of sea ice in the Svalbard area and in the Fram Strait, oil spills in connection with oil-on-water experiments in the North Sea, and algae bloom occurrences in the Baltic Sea.In these campaigns, high-resolution optical (multi-spectral) data will also be used whenever available and appropriate. By combining multi-polarisation and multi-frequency SAR data with multi-spectral radiometric data, and other auxiliary information, the aim is to improve satellite based monitoring of oil slicks in areas where look-alikes and low contrast phenomena pose extraordinary challenges. The projects will be funding by CIRFA, a centre for research based innovation hosted by UiT, a project funded by the Research Council of Norway, and the the Fram Centre. The data will found basis for several PhD dissertations. The results will be published at international conferences and in appropriate international scientific journals.
