ICoMSAR: Information content of multi-spectral SAR data

ABSTRACT

In view of an increased availability of multi-spectral datasets from several long-lasting programs of spaceborne SAR missions (e.g., Sentinel-1, ALOS, COSMO-SkyMed), this study is investigating on the advanced use of multi-spectral SAR data for various thematic applications which can be favoured by the integration of data streams acquired at different wavelengths.
The thematic applications proposed are related to the mapping and/or the parameter retrieval of forests, water bodies, cropland (crop mapping, crop biomass and soil moisture) and sea ice. These applications have been selected on the base of a number of criteria considered fundamental for the research work to be undertaken, i.e.:
– the significant contribution of SAR data to address mapping and retrieval compared to other EO data;
– the availability of multi-spectral and multi-temporal data;
– the availability of in situ or other datasets to act as reference in support of the studies.

The objectives of the project are:

  • to document the sensitivity of the multi-frequency radar signatures to the bio-/geo-physical parameters of interest;
  • to consolidate multi-wavelength retrieval schemes for a number of applications;
  • to demonstrate the performance of these retrieval schemes in the multi-frequency context;
  • to address and identify synergy potential between the different wavelengths.

These investigations are carried out by various tasks that include:

  • the survey and description of multi-spectral retrieval schemes;
  • the description and selection of multi-spectral SAR data sets;
  • the multi-spectral processing and analyses.

CNR-ISSIA will focus on the crop mapping, crop biomass and soil moisture thematic applications.
