PROCEDE ET DISPOSITIF POUR L'ELIMINATION D'ARTEFACTS DE BALAYAGE SUR UNE IMAGE FOURNIE PAR UN RADAR EMBARQUE.

摘要

The process consists in producing a two-dimensional fast Fourier transform (1) of the signals making up the radar image, in removing from the spectrum obtained the spurious frequencies relating to the artefacts by filtering (2) and in producing the inverse fast Fourier transform (3) of the spectrum ridded of its spurious frequencies. Application: airborne radars.
