The time-domain statistics of the electromagnetic bias in GNSS-R altimetry are investigated to assess the residual …
GNSS reflectometry works as a bi-static radar, where transmitter and receiver are separated by a significant distance. Since in GNSS reflectometry one receiver simultaneously can track multiple transmitters (i.e. GNSS satellites), the system also has the nature of multi-static radar.
