随着红外目标探测和精确制导技术的广泛应用,传统军事目标面临严峻的生存压力。为此,各主要军事强国采取多种措施,竞相发展目标红外辐射特性控制技术,以降低被红外探测系统捕获的概率,达到红外隐身目的。光子晶体是一种人工超颖材料,可以根据需要,通过灵活地设计其结构,改变光子在其中的传输特性。文中运用一维光子晶体带隙理论,设计了一种控制目标红外辐射特性的结构,详细给出了设计方法。计算结果表明对3~5μm和8~12μm两个红外大气传输窗口,该结构对红外辐射的抑制最高可分别达到29和21dB,具有很好的红外辐射特性控制性能。本文所述方法除为飞行器提供红外隐身设计参考外,还可用于攻防对抗仿真中红外隐身目标特性的模拟。

With the extensive application of infrared target detection and precision guidance technology, the traditional military targets face severe pressure to survive. To this end the main military powers take various measures to develop the control technology over target infrared radiation characteristics, so as to reduce the probability of being captured by an infrared detection system, achieving the purpose of infrared stealth. Photonic crystal is an artificial metamaterial, its structure can be flexibly designed according to the need, so as to change the transmission characteristics of the light in it. This paper utilizes the photonic band-gap theory of 1 D photonic crystal to design a structure being able to control target's infrared radiation characteristics, and presents the design method in detail. The calculation results show that for two infrared atmosphere transmission windows, 3~5μm and 8~12μm, the maximum suppression on the infrared radiation of the designed structure can achieve 29dB and 21dB, respectively, showing good control performance of infrared radiation characteristics. The method described in this paper can not only provide reference for infrared stealth design, but also can be used in the simulation of infrared stealth target characteristics in the offensive and defensive combat simulation.
