Description

A kind of infrared/laser/microwave/millimeter wave bore beam synthesizer altogether
Technical field
The utility model relates to a kind of beam synthesizer, particularly a kind of infrared/laser/microwave/millimeter wave bore beam synthesizer altogether, be mainly used in infrared/laser/microwave (millimeter wave) complex imaging and survey the guidance semi-matter simulating system.The utility model belongs to the crossing domain of optics and microwave technology.
Background technology
The dual-mode/multi-mode Compound Guidance Technology that infrared/laser/microwave/millimeter wave any two kinds and above mode combinations form is one of the most promising current precision Guidance Technique.It makes infrared guidance, laser guidance, microwave guidance and millimeter-wave guidance institutional advantage complementary, can make up the shortcoming of each side simultaneously.In order to carry out design, checking, test and the assessment of infrared/laser/microwave/millimeter wave combined guidance in the laboratory, need to set up infrared/laser/microwave/millimeter wave combined guidance semi-matter simulating system accordingly.Realize the Main Means of analog composite guidance in infrared/laser/microwave/millimeter wave combined guidance semi-matter simulating system during beam synthesizer.The effect of beam synthesizer be exactly with infrared target image signal, laser echo signal, microwave signal, millimeter-wave signal in twos or multi-signal project same detection viewing field and do not interfere with each other at Spatial Coupling.Infrared/laser/microwave/millimeter wave beam synthesizing technology is one of gordian technique of common bore dual-mode/multi-mode combined guidance semi-matter simulating system.
In the development and design of beam synthesizer, mainly take with the dielectric-slab of infrared reflection film, technology paths such as frequence-selective surface, diffraction optical device, 1-D photon crystal, metallic mesh film, prism array on foam matrix as main.
Up to the present, plating infrared reflection film on the dielectric matrix flat board is the most ripe a kind of technology.Beam synthesizer is comprised of the relatively thick dielectric matrix flat board that is coated with the multilayer infrared refleccting coating.According to boundary-layer theory, have in theory and prepare the possibility that all has the multilayer dielectric film of good reflection characteristic at medium-wave infrared, LONG WAVE INFRARED and laser wavelength.Dielectric substance has the good characteristic that sees through to microwave/millimeter wave, and the multilayer infrared refleccting film thickness maximum of plating on media plate simultaneously is in micron dimension, and is little to the absorption of microwave/millimeter wave in theory.The thickness of matrix flat board also should be optimized, and guaranteeing has enough little absorption to microwave/millimeter wave, prevents simultaneously the distortion on surface.Due to the restriction of processing technology, the beam synthesizer greatest diametrical dimension<800mm of this version of up to the present reporting.
Frequency-selecting face on foam matrix (FSS) is the layering directrix plane structure that is formed by certain specific distribution mode periodic arrangement by a large amount of parasitic elements.These parasitic elements are generally the conduction microplates, and its interval and size have determined the performance of FSS.FSS has good selectivity to electromagnetic transmission and reflection, and the electromagnetic wave in its passband is presented the all-pass characteristic, and the electromagnetic wave in its stopband is total reflection characteristic, namely has the spatial filtering function.Frequence-selective surface is that with respect to a large advantage of deielectric-coating it can do size very large, to reduce the diffraction impact on the millimeter wave field.But its shortcoming is the surface that makes and can not show a candle to the deielectric-coating smooth surface of making of the traditional optical film plating process, and the impact on the infrared band optical characteristics that rough surface causes is the maximum shortcoming part of this technology.
The main part that diffraction optical device (DOE) is better than front two technology is to make beam synthesizer to place perpendicular to the microwave/millimeter wave sight line.Diffraction optical device is in smooth surface etch toothing and is coated with metal film formation grating, is used for reflective infrared/laser signal.This structure allows beam synthesizer vertical with the microwave/millimeter wave direction of propagation, but the DOE structure is still more favourable than another kind of polarized state to a kind of polarized state of microwave/millimeter wave.In addition, limited caliber size can cause edge effect, thereby causes angular error in the monopulse detection system.The minimum dimension of DOE can consider from the needs of infrared scene projection, mainly decided to the distance of unit under test by the field angle of the projector and DOE.
The 1-D photon crystal beam synthesizer is alternately laminated the forming of two or more media by differing dielectric constant, form forbidden photon band, can realize the reflective infrared/laser signal of full angle, random polarization state, the transmitance of microwave/millimeter wave is mainly by classical insulation and the structures shape of matrix.1-D photon crystal generally adopts coating method to be prepared, and simplicity of design, cost is low, precision is high.The homogeneity of photonic crystal and size thereof still are subject to the restriction of coating process.
The metallic mesh film is a kind of conducting film, and its cycle is much larger than the wavelength of infrared/laser, and simultaneously much smaller than the wavelength of microwave/millimeter wave, can realize to the high-efficiency shielding of microwave/millimeter wave with to the high transmission of infrared/laser.Can realize the synthetic report that still up to the present yet there are no application of wave beam.
Beijing Institute of Technology's utility model the beam synthesizer made of inorganic and organic material, the patent No.: ZL200610120495.7 infrared radio frequency beam synthesizer, be coated with on inorganic medium that multilayered medium is infrared increases anti-film, and prepare blazed grating outside inorganic medium, make the curved surface of certain curvature at the organic media outside surface, scope difference according to infrared projection visual field, the blazed grating profile is prepared into circle or polygon, inorganic medium adopts the polygon of fritter to be spliced into large-area slab construction, stick on the organic substrate surface, difficulty of processing and cost have been reduced.But the method still is subjected to the restriction of processing technology and scantling.For example: because inorganic medium is pasted on organic media, so the size of organic media has still limited the full-size of beam synthesizer.
