With the development of the infrared detection technology,infrared detector has been extensively applied in many kinds of guided weapon and reconnaissance system,and it has posed a seriously threat to the survival ability of military targets,therefore the important significance of infrared camouflage technology becomes extremely important for military targets.At present,infrared detector mainly uses the infrared radiation wavebands on 3~5 μm and 8~14 μm to detect targets,while infrared camouflage technology also needs to countermove these two infrared wavebands.The background environments for various military targets was analyzed,the specific applications of the infrared camouflage technology in different backgrounds and developments were summarized,and the targets in sky background,sea background and land background were analyzed and discussed.The challenges in infrared camouflage technology are pointed out,and in the end,the development tendency of infrared camouflage technology is prospected.
