Abstract

The invention discloses a common-caliber beam forming device for infrared rays / lasers / microwaves millimeter waves, relates to a common-caliber beam forming device, and belongs to the crossing field of the optical technology and the microwave technology. The common-caliber beam forming device for the infrared rays / the lasers / the microwaves / the millimeter waves comprises an infrared ray / laser reflecting plane, a supporting flat plate, an air layer and adjusting mechanisms. The infrared ray / laser reflecting plane is formed by a plurality of sub-pieces in a spliced mode. The supporting flat plate is formed by a plurality of sub-plates in a spliced mode. The adjusting mechanisms are used for fixing and supporting the sub-pieces and capable of achieving the horizontal adjustment, the vertical adjustment and the longitudinal adjustment of the sub-pieces, the plane type of the infrared ray / laser reflecting plane is adjusted by adjusting the adjusting mechanisms to ensure the infrared ray / laser reflecting planes of all the sub-pieces are in a same plane. The thickness of the air layer can be slightly adjusted through the longitudinal adjustment of the adjusting mechanism, so that the transmitting frequency band of the microwaves / millimeter waves can be adjusted slightly. The adjusting mechanisms had a locking function after adjustment is finished. The common-caliber beam forming device for the infrared rays / the lasers / the microwaves / the millimeter waves is mainly applied to composite imaging detecting guide semi-physical simulation systems for the infrared rays / the lasers / the microwaves(the millimeter waves).

Description

technical field [0001] The invention relates to a beam forming device, in particular to an infrared / laser / microwave / millimeter wave common-aperture beam forming device, which is mainly used in an infrared / laser / microwave (millimeter wave) composite imaging detection guidance hardware-in-the-loop simulation system. The invention belongs to the intersection field of optics and microwave technology. Background technique [0002] The dual-mode / multi-mode composite guidance technology, which is a combination of any two or more modes of infrared / laser / microwave / millimeter wave, is one of the most promising precision guidance technologies at present. It makes the advantages of infrared guidance, laser guidance, microwave guidance and millimeter wave guidance system complementary, and can make up for the shortcomings of each party at the same time. In order to design, verify, test and evaluate infrared / laser / microwave / millimeter wave composite guidance in the laboratory, it is nece...
