Abstract

PURPOSE:to improve beam flux concentration, by selecting the configuration and alignment of a small size reflector which reflects the beam from the primary radiator to a rotary parabolic reflector. CONSTITUTION:The small size reflector 2 which reflects the beam from the primary radiator placed adjacent to the focus F of the rotary parabolic reflector 1 to the rotary parabolie reflector 1 is to be an oval shape having double focuses F, F'. One of the focuses F is to coincide with the focus F of the rotary parabolic reflector F and the small size reflector is so mounted that it is to be rotated around the center axis of the rotary parabolic reflector 1. With such an arrangement, after the beam from the primary radiator is reflected by the small size radiator 2, it is proceeded through the other focus F' and, reflected to the rotary parabolic reflector 1. Therefore the rotary beam of conical scanning can be created by making use of double focus and the beam flux is concentrated precisely in the same direction.
