Description
Technical field
The present invention relates to a kind of infrared inhibition devices based on Seebeck effect, belong to infrared suppressing technical field.
Background technique
Infrared suppressing technology is with infrared detection, captures the development of target and terminal guidance technology and gradually grow up
's.Any object is higher than absolute zero, all can outside infrared radiation, if there are temperature difference, radiation for target and environmental background
Infrared ray peak wavelength just have difference, there are difference with environmental background infrared signature for target, are easily detected by infrared detector
And it identifies.One main method of infrared suppressing is exactly to reduce the temperature of target, to reduce the temperature of target and environmental background
Difference, to reduce target and environmental background infrared signature difference.The 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 research achievement, and during this
Forward-looking infrared system goes into operational service, and point source IR guidance technology is also mature.The 1970s is infrared suppressing technology
The fundamental research stage and experimental stage, this period achieve certain theoretical result, while obtaining certain examination
Data are tested, but inhibit the degree for not reaching practical application.It is that infrared suppressing technology develops rapidly after the 1980s
Period achieves a large amount of achievement, and various infrared stealth technologies initially enter practical level.The U.S. has developed red at this time
Outer invisbile plane, American and Britain, Sweden etc. develop infrared smoke screen, and English, U.S. joint research and development are at stealthy airport, and by infrared stealth skill
Art is successfully applied in MISSILE LAUNCHING.
Infrared suppressing technology mainly includes three aspects: reducing Target Infrared Radiation intensity；The infrared signature of simulation background；
Infrared deformation.
It reduces target itself infrared intensity: making the difference of the infrared intensity of target and the infrared intensity of background
It does not minimize, the probability for identifying it by detector reduces.It includes following several main methods again: cross-ventilation heat dissipation,
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 room temperature target is close with background, but the heat with 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 coordinates target and the infra-red radiation state of background mutually, and the infrared image of target is finally made to become back
A part of 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 and guidance system are exactly to identify target by these special characteristics of target.Infrared deformation is then by changing target portion
The relative value of dividend external radiation and relative position, it is special to change the specific infrared image that target is easily identified by infrared imaging system
Sign makes identification become difficult or generate 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
In barrier and target the aspect of infrared counteraction three.The following infrared coating will mutually be fitted with the spectral performance of coating with ambient enviroment
It answers, and takes into account the effect of anti-millimetre-wave radar and anti-chemical pollution, while there are also " hot camouflage color " camouflage effectiveness.Exactly develop low red
The coating and coating of outer emissivity, and develop the infrared coating material that emissivity varies with temperature.
Infrared camouflage net mid and far infrared wave band camouflage performance near or above the puppet on visible light and near infrared band
Dress, while there is good radar camouflage characteristic.Infrared camouflage net is used for high-temperature targets Shi Yingyu Infra-Red Suppression System height
Coordinate, specific method is the infrared camouflage net that development can simulate that degree/day changes around object background, and is found more reasonable
Insulating layer structure and corresponding construction process.
