Software Defined Radio system for GNSS-Refectometry: activities performed at the Politecnico of Turin (Italy)
The GNSS signals are an important active source for Earth’s remote sensing in L band. Experiments performed over sea and land surfaces demonstrated the capability of GNSS-Reflected signals (GNSS-R) for remote sensing purposes. Presently, many research groups are focusing their efforts in developing...
