摘要
红外伪装技术是指隐藏或改变目标红外辐射特征的技术,对于提高目标的生存率具有重大意义。多波段探测技术的发展,给传统的红外伪装技术带来了严峻的挑战,使得多波段兼容红外伪装材料的研究变得十分紧迫。针对这一挑战,首先须厘清各波段的伪装要求,其次应合理利用各波段材料电磁响应的不同和结构尺寸的差异,设计分层次结构以满足不同波段的光谱要求。最后,应认识到现有研究存在的不足,向着适应更多探测波段、应用场景,制备工艺更简便、成本更低、应用性更优的方向发展。
Infrared camouflage refers to the capability of hiding or changing the infrared radiation characteristics,hence improving the survival rate of the objects.However,advanced multi-band detection technologies have emerged as a significant threat to the objects,necessitating the development of multi-band compatible infrared camouflage technologies.To address the challenge,it's of vital importance to clarify the camouflage requirements of different bands and design hierarchical structures based on the difference in electromagnetic response and structure size in these bands.Finally,it's essential to recognize the shortcomings of existing research and promote camouflage technologies more applicable,easy to prepare,and lower cost.
