Fig. 8.2 Sketch of the GNSS-R as a multi-static system of observation. From each individual
receiver, a large number of GNSS transmitted signals can be collected after their reflection off the
Earth surface. This set of bi-static observations occur at different azimuth and elevation angles,
providing a mosaic of “glistening zones”. As the receiver moves along its trajectory, the scanned
surface takes an irregular, highly dense and wide swath comb-like pattern
Note that other contributions to the receiver electromagnetic field are also
possible, such as those coming from atmospheric ducting (atmospheric multi-path),
or from reflection off other objects surrounding the receiver or along the propagation
path. These contributions will be neglected in this chapter.
