Abstract :
The use of global navigation satellite systems (GNSS) reflected signals has been pinpointed as a promising technique for the retrieval of geophysical parameters. This article describes the implementation of a GPS reflectometer to obtain real-time delay-Doppler maps (DDM) to infer sea-state data, needed to correct the L-band brightness temperature and measure sea salinity. This instrument will be based on a FPGA-embedded system, and is part of the PAU concept.
