Title (EN) PULSE DOPPLER MTI APPARATUS
(FR) APPAREIL MTI A EFFET DOPPLER A IMPULSIONS
Abstract:
(EN) A pulse Doppler MTI apparatus equally displays motions of any direction in the fault plane, prepares a file of bipolar video signals using reception signals of one scan as a frame based upon echo reception signals of a plurality of times of scanning by the reception multi-beam forming, and effects the two-dimensional mutual correlation processing for the data of the file after the components related to fixed reflection points have been removed.
(FR) L'appareil MTI à effet Doppler à impulsions affiche des mouvements dans une direction quelconque dans le plan de faille, prépare un fichier de signaux vidéo bipolaires en utilisant des signaux de réception d'un balayage en tant que trame en se fondant sur des signaux de réception d'écho d'une pluralité de balayages par la mise en forme des faisceaux multiples de réception, et effectue le traitement de corrélation mutuelle bidimensionnelle des données du fichier après que les composantes relatives à des points de réflexion fixes ont été éliminées.
