The use of signals transmitted by global navigation satellite systems (GNSS) as a tool for earth remote sensing has been attracting growing interest in recent years, in particular for spaceborne missions. For such techniques, several on‐board processing strategies have been proposed, either based on on‐board signal generation or based on ‘blind’ interferometric processing. Presented is a comprehensive comparison of these two categories of GNSS‐R processing techniques by introducing a generalised decomposition of the cross‐correlation waveform.
