Abstract

The invention discloses an infrared radiation transmitting conformal millimeter wave antenna, which consists of an infrared radiation transmitting window substrate, thin film chips, a thin film ground strap and a feeder line, wherein the feeder line forms good ohmic contact with the thin film chips; the thin film chips are arranged on the inner surface of the window substrate at intervals; the feeder line is oppositely positioned on the inner surface of the window substrate; and the thin film ground strap is covered on the outer surface of the window substrate. A millimeter wave antenna is integrated on an infrared window of the conventional infrared detection equipment on the basis of the conventional millimeter wave antenna technology to form a millimeter wave / infrared dual-mode detection conformal antenna which is used for realizing millimeter wave / infrared dual-mode shield-free, coaxial, common-caliber and conformal composite detection and identification.

Description

technical field [0001] The invention relates to a conformal millimeter-wave antenna capable of penetrating infrared radiation, which belongs to the dual-mode compound detection and identification technology. Background technique [0002] At present, infrared imaging devices using focal plane arrays can provide high-resolution images day and night, but their performance is significantly reduced in heavy fog, smoke, dust or snow, and infrared detection cannot give distance and speed data of targets , millimeter-wave radar has the advantages of all-weather microwave radar and good penetration of smoke and fog, and at the same time has higher target resolution due to its narrow beam. The combined use of wave radar will significantly improve safety, like the American aircraft autonomous approach and landing system AALC, which uses a combination of 8-12 micron long-wave infrared and 95GHz millimeter wave to achieve safe landing in weather conditions with low clouds and zero visibi...
