Abstract

L'INVENTION CONCERNE LES RADARS ULTRASONORES A BALAYAGE LATERAL. ELLE SE RAPPORTE A UN RADAR ULTRASONORE AYANT UN ARRANGEMENT EMETTEUR-RECEPTEUR DIRIGE D'UN COTE DU NAVIRE, PERPENDICULAIREMENT A LA ROUTE DE CELUI-CI, ASSURANT UN BALAYAGE ELECTRONIQUE REPETE DANS UN SECTEUR EN ARC DE CERCLE. UNE SERIE DE BALAYAGES A DISTANCES CROISSANTES EST EFFECTUEE APRES EMISSION DE CHAQUE SIGNAL, ET UN DISPOSITIF D'ECHANTILLONNAGE 46 FONCTIONNE PENDANT UNE TRANCHE TEMPORELLE PREDETERMINEE DE CHAQUE BALAYAGE, LE GISEMENT DU FAISCEAU ECHANTILLONNE DEPENDANT DE LA POSITION DES TRANCHES TEMPORELLES PAR RAPPORT AU DEBUT DU BALAYAGE. APPLICATION AUX RADARS ULTRASONORES A BALAYAGE LATERAL DES NAVIRES.
