红外探测与红外隐身材料研究进展

Technologies related with infrared radiation (IR) detection and IR stealth have been wildly applied in the modern military field. IR signal of weapons such as aircraft is more prominent with the performance improving. Meanwhile, The detection ratio and sensitivity of the third generation of IR detector based on the photoelectric effect are greatly improved. Therefore, IR stealth technology becomes a necessary means to improve the survivability and combat effectiveness of the battlefield. In this paper, based on the IR characteristics of the aircraft, the IR signal distribution and effect factors are analyzed, the operating principles, detection performance and development trend of the third generation IR detector materials presented by HgCdTe are summarized, the application status of low emissivity coating in the field of infrared stealth is introduced, the stealth mechanism and research progress of various emerging materials are reviewed. Finally, the future research directions of materials for IR detection and IR stealth are prospected in accordance with the service requirement.
