A method (100; 200) for digital signal processing (S(t)) of a pulse and scanning radar during an observation of a coastal zone in land/sea detection mode, the signal being sampled according to a two-dimensional temporal map, a distance dimension (d) and a recurrence dimension (rec), comprising: the selection of a digital terrain model file (MNT) of the observed coastal zone; transformation (110; 210) of the temporal map and/or of the digital terrain model file to obtain a transformed temporal map and/or a transformed digital terrain model file the data of which are expressed in a common reference frame; construction (120) of a mask (MT; MF) from the transformed digital terrain model file; and, application (130) of the mask to the samples (E(d, rec); E(d, Af)) of the map associated with the transformed temporal map, in such a way as to obtain filtered samples (Ef(d, rec); Ef(d, Δf)). |
