Abstract
In this project report, the main outcomes relevant to the Sino-European Dragon-4 cooperation project ID 32235 “Microwave satellite measurements for coastal area and extreme weather monitoring” are reported. The project aimed at strengthening the Sino-European research cooperation in the exploitation of European Space Agency, Chinese and third-party mission Earth Observation (EO) microwave satellite data. The latter were exploited to perform an effective monitoring of coastal areas, even under extreme weather conditions. An integrated multifrequency/polarization approach based on complementary microwave sensors (e.g., Synthetic Aperture Radar, scatterometer, radiometer), together with ancillary information coming from independent sources, i.e., optical imagery, numerical simulations and ground measurements, was designed. In this framework, several tasks were addressed including marine target detection, sea pollution, sea surface wind estimation and coastline extraction/classification. The main outcomes are both theoretical (i.e., new models and algorithms were developed) and applicative (i.e., user-friendly maps were provided to the end-user community of coastal area management according to smart processing of remotely sensed data). The scientific relevance consists in the development of new algorithms, the effectiveness and robustness of which were verified on actual microwave measurements, and the improvement of existing methodologies to deal with challenging test cases.
Highlights
With respect to the detection of metallic targets at sea, the performance of state-of-theart multipolarization detectors was intercompared in a very challenging test case, namely wind turbines located in a large intertidal flat area
With respect to the evaluation of the risk associated with coastal erosion, a processing chain that exploited multipolarization Synthetic Aperture Radar (SAR) data to (a) extract the coastline and (b) classify the inland area near the extracted coastline using the dominant scattering mechanism was developed and tested on actual SAR measurements
Experimental results showed the ability of polarimetric SAR measurements to assist policy makers though an added-value product that jointly shows the coastline and classifies the land use
Summary
In this paper the main scientific achievements stemming from the Dragon-4 cooperation programme are discussed. The main scientific goal of the project relied on the exploitation of microwave satellite measurements to generate innovative added-value products to observe coastal areas under extreme weather conditions. The methods/products developed under the Dragon-4 cooperation were based on a deep and fruitful cooperation between Chinese and European (including Italy, UK, Spain, France and Netherlands) partners that called for complementary expertise. Young faculty as well as Master’s and Ph.D. students contributed to the understanding of the phenomena under study, i.e., coastal water pollution, coast erosion, ship and metallic target detection
