Abstract :
The assumed potential of Global Navigation Satellite System Reflections (GNSS-R) to retrieve geophysical parameters has yet to be fully shown. The implementation of a GNSS-R receiver to compute real-time Delay-Doppler Maps (DDM) will be a significant step forward. In the PAU instrument these DDMs will be obtained along with co-located data of brightness temperature. To relate both measures a parameterization of the DDM is performed. Preliminary results have been obtained.
