Wind retrieval for GNSS reflectometry from techdemosat-1

The main purpose of this study is to propose and validate a new algorithm for wind speed retrieval over the ocean using Global Navigation Satellite System-Reflectometry (GNSS-R). The proposed method is based on a Least Squares (LS) estimation from the volume of the scattered power function. Real DDMs collected by the space GNSS receiver-remote sensing instrument (SGR-ReSI) on board the TechDemoSat-1 (TDS-1) satellite and the Advanced SCATterometer (ASCAT) wind speed measurements are used for validation.
