Abstract

The invention discloses a conformal antenna for millimeter wave / infrared dual mode composite detection. The conformal antenna is composed of a window substrate, compound semiconductor film surface-mounted sheets, an insulating medium substrate, a compound semiconductor film grounding piece which are penetrable of infrared radiation and feeder lines in good ohmic contact with the compound semiconductor film surface-mounted sheets. The compound semiconductor film surface-mounted sheets are arranged on the inner surface of the window substrate at intervals, and the corresponding feeder lines are arranged on the inner surface of the window substrate. The inner surface of the window substrate, the compound semiconductor film surface-mounted sheets and the feeder lines are coated by the insulating medium substrate; and the compound semiconductor film grounding piece is covered on the surface on one side of the insulating medium substrate away from the window substrate. According to the conformal antenna for millimeter wave / infrared dual mode composite detection, based on the traditional millimeter wave antenna technology, the millimeter wave antenna is integrated on a window substrate of a prior infrared detection device to form the conformal antenna for millimeter wave / infrared dual mode composite detection; and shielding-free, coaxial, co-aperture and conformal composite detection and recognition of the millimeter wave / infrared dual mode are achieved.

Description

technical field [0001] The invention relates to a conformal antenna for millimeter wave / infrared dual-mode composite detection, which belongs to the dual-mode composite 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 visi...
