Abstract (en)
The monopulse antenna construction has two waveguides (41,42) side by side on a metallic base (25) for feeding antennas. The waveguides are fed by narrow height waveguide sections (47,48) with a backing short circuit and microstrip transitions (44,45). The transitions are placed between the change of height of the waveguides. The transitions are fed by a symmetrical feed from a hybrid ring, forming sum and difference monopulse patterns.
Abstract (fr)
L'invention concerne une source monopulse pour antenne focalisante. La source comporte au moins deux guides d'onde (41, 42) usinés dans la semelle métallique (25) supportant le circuit d'émission et des réception hyperfréquence (23, 49, 50, 53, 54, 55, 56, 57) de l'antenne (2, 3, 11). Application : notamment sources primaires pour radars fonctionnant en onde millimétrique. <IMAGE>
