Description
Technical field
The present invention relates to a kind of infrared inhibition device based on Seebeck effect, belong to infrared suppressing technical field.
Background technology
Infrared suppressing technology is progressively grown up with infrared detection, the development of capture target and terminal guidance technology
's.Any object is higher than absolute zero, all can outside infrared radiation, if there is temperature difference with environmental background in target, radiation
Infrared ray peak wavelength just have a difference, there is difference in target, easily detected by infrared detector with environmental background infrared signature
And recognize.One main method of infrared suppressing is exactly to reduce the temperature of target, to reduce the temperature of target and environmental background
Difference, so as to reduce target and environmental background infrared signature difference.1960s is the early-stage development rank of infrared suppressing technology
Section, research institution has started the research and development of infrared suppressing technology, but makes slow progress, without specific achievement in research, and during this
Forward-looking infrared system goes into operational service, and point source IR guidance technology is also ripe.1970s is infrared suppressing technology
The fundamental research stage and experimental stage, this period achieves certain theoretical result, while obtaining certain examination
Data are tested, but suppress to be not reaching to the degree of practical application.It is that infrared suppressing technology is developed rapidly after 1980s
In period, substantial amounts of achievement is achieved, and various infrared stealth technologys initially enter practical level.The U.S. now have developed red
Outer invisbile plane, American and Britain, Sweden etc. develop infrared smoke screen, and English, U.S. joint research and development are into stealthy airport, and by infrared stealth skill
Art is successfully applied in MISSILE LAUNCHING.
Infrared suppressing technology mainly includes three aspects：Reduce Target Infrared Radiation intensity；The infrared signature of simulation background；
Infrared deformation.
Reduce target itself infrared intensity：Make the difference of the infrared intensity of target and the infrared intensity of background
It Jin Liang not reduce, reduce its probability recognized by detector.It includes following several main methods again：Cross-ventilation radiating,
Infrared coating material and coating, thermal insulation layer, hot waste gas cooling system, in target infrared countermeasure.
The infrared signature technology of simulation background：The heat radiation characteristic of normal temperature target is close with background, but with the heat of background
Radiation feature still has different, equally can be identified and find.Simulation background infrared signature refers to by changing target
Infra-red radiation branch feature, makes the infra-red radiation state of target and background mutually coordinate, and finally makes the infrared image of target and turns into the back of the body
A part for scape infrared image, effectively reduces the probability that target is found by detector.
Infrared deformation technology：Different targets has specific Infrared Image Features, infrared imaging in the state of difference
Investigation is exactly these special characteristics by target to recognize target with guidance system.Infrared deformation is then by changing target portion
The relative value and relative position of dividend external radiation, to change the specific infrared image spy that target is easily recognized by infrared imaging system
Levy, identification is become difficult or produce wrong identification.
The development trend of various countries' infrared suppressing technology is mainly reflected in infrared coating material and coating, infrared camouflage net and screening
Barrier and target in three aspects of infrared counteraction.Following infrared coating will mutually be fitted with the spectral performance of coating with surrounding environment
Should, and the effect of anti-millimetre-wave radar and anti-chemical pollution is taken into account, while there is " hot camouflage color " camouflage effectiveness.Exactly develop low red
The coating and coating of outer emissivity, and the infrared coating material that development emissivity is varied with temperature.
Infrared camouflage net mid and far infrared wave band camouflage performance near or above the puppet on visible ray and near infrared band
Dress, while having good radar camouflage characteristic.Should be with Infra-Red Suppression System height when infrared camouflage net is for high-temperature targets
Coordinate, specific method is the infrared camouflage net that development can simulate that degree/day changes around object background, and is found more reasonably
Insulating layer structure and corresponding construction process.
The infrared signature of target depends primarily on the temperature of target, at present, in target infrared countermeasure be comprehensive
Close on the basis of the operational requirements and physical property that consider target, the redesign of heat is carried out to target, one is target endogenous pyrogen
Redesign, another is the redesign of target self structure, material, shape and application method.But not by heat energy,
