Abstract

ANTENNE A PLANS PARALLELES DU TYPE PILL-BOX OU FROMAGE DONT LA PARTIE CYLINDRO-PARABOLIQUE EST CONSTITUEE PAR UN REFLECTEUR SEMI-TRANSPARENT ET DONT LE PLAN FOCAL EST CONSTITUE PAR UN REFLECTEUR POLARISEUR. LE REFLECTEUR SEMI-TRANSPARENT CYLINDRO-PARABOLIQUE EST CONSTITUE PAR UN RESEAU DE FILS PARALLELES AU PLAN DE POLARISATION DE L'ONDE EMISE PAR LA SOURCE. LE REFLECTEUR POLARISEUR EST FORME D'UNE PLAQUE REFLECTRICE SITUEE A L4 D'UN RESEAU DE FILS PARALLELES INCLINES A 45 PAR RAPPORT AU PLAN DE POLARISATION DE L'ONDE INCIDENTE. APPLICATION AUX ANTENNES DE SURVEILLANCE ET DE DESIGNATION D'OBJECTIF.
