## 5 Conclusions  
In this work, the capabilities of the airborne SAR infrastructure developed at IREA-CNR have been presented. The infrastructure consists of a flight segment and a ground segment. The flight segment includes the MIPS SAR system based on FMCW technology and operating with a single-pass InSAR configuration in the X-band or with a fully polarimetric configuration in the L-band. The MIPS sensor is mounted on board chartered aircraft, since IREA-CNR is not equipped with its own aircraft. The ground segment includes a multi-core IT platform for data storage and processing and an SAR data processing chain, allowing us to generate added-value products, such as soil moisture maps, DEMs, ground motion maps and so on, from the acquired raw SAR data. The data processing chain jointly developed by IREA-CNR and Universita Parthenope was designed to guarantee the high quality of the final products through the use of a time-domain focusing strategy while ensuring sound processing times due to the implementation of a parallel programming strategy that takes advantage of the multi-core capability of the IT platform of the infrastructure. Overall, the infrastructure masterfully frames the current and upcoming objectives of the remote sensing sector and allows IREA-CNR to plan and execute airborne SAR campaigns and to process the acquired data. We further remark that the infrastructure is aimed, first of all, at developing research activities; however, it also represents a valuable support for the emergency prevention and management activities of civil protection authorities. The technical aspects related to the flight and ground segments of the infrastructure have also been presented. In particular, some preliminary products (namely, an RFI-filtered SLC) achieved with MIPS L-band data were reported. In this regard, it is stressed that MIPS acquisition campaigns in the L-band are planned for the very near future, with the aim of collecting polarimetric datasets to be used for the retrieval of ground parameters such as the soil moisture and repeat-pass InSAR datasets for the application of the DInSAR technique. More advanced products achieved with MIPS X-band data were also presented. In particular, the results of the single-pass InSAR processing chain leading to the generation of a DEM of the volcanic area of Stromboli, southern Italy, were reported. The capabilities of the infrastructure were also analyzed within the framework of the activities that IREA-CNR carries out as the National Centre of Competence of the Department of Civil Protection of the Italian Presidency of the Council of Ministers with the short time target of creating an infrastructure for the periodic monitoring of volcanic areas, and capable of being rapidly operative during crisis events. In this context, the airborne infrastructure capabilities were analyzed in terms of response times and characteristics of the final products. In particular, the Stromboli dataset mentioned above was considered as a real case study. The considered airborne dataset consists of eight X-band single-pass interferometric MIPS acquisitions corresponding to about 130 GByte of radar data, which guarantees full coverage of Stromboli Island.
