Ocean wave periods are estimated using measurements of S-band signals-of-opportunity reflections from the sea surface. The measurements were collected on an oil platform and show a time evolving Doppler centroid frequency and spectral width due to th

Signals of opportunity (SoOp) reflectometry (SoOp-R) is a maturing field for geophysical remote sensing as evidenced by the growing number of airborne and spaceborne experiments. As this approach receives more attention, it is worth analyzing SoOp-R'

Delay-Doppler maps (DDMs) are generally the lowest level of calibrated observables produced from global navigation satellite system reflectometry (GNSS-R). A forward model is presented to relate the DDM, in units of absolute power at the receiver, to

Reflectometry is one of many new applications made possible by freely available global navigation satellite system (GNSS) signals. Reflectometry measurement geometry has some features that are significantly different from conventional radar or radiom
