Time-domain Statistics of the Electromagnetic Bias in GNSS-Reflectometry [PDF]
Remote Sensing, 2015 Global Navigation Satellite Systems-Reflectometry (GNSS-R) is an emerging remote sensing technique that uses navigation signals reflected on the Earth’s surface as sources of opportunity for scatterometry and altimetry.

Estimating Wave Direction Using Terrestrial GNSS Reflectometry [PDF]
Remote Sensing, 2019 The signal-to-noise ratio (SNR) data are part of the global navigation satellite systems (GNSS) observables. In a marine environment, the oscillation of the SNR data can be used to derive reflector heights. Since the attenuation of the SNR oscillation is
