3D multibaseline SAR Tomography is emerging at the operational level for spaceborne monitoring of forest biomass, nevertheless problems still stands in particular about radiometric accuracy of the most diffused superresolution Capon processing. In this paper two alternative adaptive algoritms are proposed for Tomography, and tested by simulations and first P-band real data trials.
SAR images from Italian COSMO-SkyMed mission can have a significant impact on the production and updates of land cover maps. However, for the full exploitation of the data and their application to nationwide extensions, robust automatic procedures need to be designed. In this paper we present the preliminary results obtained by the implementation of a processing scheme using COSMO-SkyMed images to...
The availability of synthetic aperture radar (SAR) data with high spatial resolution offers great potential for environmental monitoring due to the insensitivity of SAR to atmospheric and sunlight-illumination conditions. In this paper, an unsupervised change detection method for SAR images at medium to high resolution is proposed. The image ratioing approach is adopted, and a Bayesian unsupervised...
In this work, an integration of microwave data coming from different sensors (SMAP, Sentinel-1, AMSR2) has been attempted, in order to obtain an improved estimation of hydrological parameters and in particular of the Soil Moisture (SMC). The failure of radar sensor in SMAP satellite induced to look for other available microwave frequencies, both from active (e.g. Sentinel-1, C band) and passive sensors...
With the rapid development of spaceborne Synthetic Aperture Radar (SAR) and the increasing need of ship detection, research on adaptive ship detection in spaceborne SAR imagery is of very great importance. Focusing on practical problems of adaptive ship detection, this paper present a highly adaptive ship detection method for spaceborne SAR imagery. It applies two different detection strategies to...
By providing high quality flood maps a spaceborne SAR can be an effective source of information. These maps support civil protection authorities for disaster risk reduction. Here we propose a methodology for identifying floods that occur on different types of land cover, such as urban areas, bare and poorly vegetated soil and vegetated areas. Our approach takes advantage of polarimetric SAR data and...
