ASI's "multi-mission and Multi-Frequency SAR" Program for Algorithms Development and SAR Data Integration Towards Scientific Downstream Applications.

In continuity with the investments made on SAR technologies in the last two decades by the Italian Space Agency (ASI), the "Multi-mission and multi-frequency SAR" program currently supports ten R&D projects aiming to design, develop and test innovative algorithms for exploitation of multi-mission/multi-frequency SAR data. Perspectives of engineering and pre-operational development are demonstrated with regard to various application domains (i.e. agriculture, urban areas, natural hazards, cryosphere, sea and coast). Access to COSMO-SkyMed and SAOCOM images is facilitated by ASI to allow the research consortia to achieve an effective multi-frequency SAR data integration. The program represents a foundational step in the ASI's roadmap towards "scientific downstream applications", i.e. applications enabled by the exploitation of mature and validated algorithms that have been originally developed to answer scientific questions and/or retrieve geophysical parameters, and have been brought to the stage that they can generate products that address specific user needs beyond scientific and academic purposes only.
