Title:
SPATIAL COMPOSITE ANTENNA DEVICE, AND MANUFACTURING METHOD FOR MIRROR SURFACE CORRECTION REFLECTION MIRROR RELATED TO PRIMARY AND SUB MIRRORS
Document Type and Number:
Japanese Patent JP2014143525
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a spatial composite antenna device that can vary radiation power pattern, and to provide a manufacturing method for a mirror surface correction reflection mirror related to primary and sub mirrors.SOLUTION: A spatial composite antenna device 10 of the present invention includes: a phased array feed section 13 on which a plurality of radiation elements 14 of the same radiation gain are regularly arranged; a sub mirror 12 having a mirror surface correction reflection mirror that reflects a radiation beam radiated from the plurality of radiation elements 14; and a primary mirror 11 having a mirror surface correction reflection mirror for forming a prescribed radiation power pattern by spatially synthesizing the radiation beam reflected by the sub mirror 12. In a manufacturing method for the mirror surface correction reflection mirror related to the primary mirror 11 and the sub mirror 12 of the present invention, the mirror surface shape is corrected and optimized on the basis of a correction standard parabolic surface so as to achieve a target gain value set for each of the primary mirror 11 and the sub mirror 12, while inspecting whether it is possible to change the radiation gain in a prescribed range within a specific region of the service area by the radiation element 14 controlling an excitation amplitude value and excitation phase value.
