红外隐身技术通过降低或改变目标的红外辐射特征,实现对目标的低可探测性.这可通过改进结构设计和应用红外物理原理来衰减、吸收目标的红外辐射能量,使红外探测设备难以探测到目标.红外隐身技术于20世纪70年代末基本完成了基础研究和先期开发工作,并取得了突破性进展,已由基础理论研究阶段进入实用阶段.从20世纪80年代开始,国外陆海空三军研制的新式**已经广泛采用了红外隐身技术.首先分析了红外隐身原理,然后研究了红外隐身技术的应用和发展趋势.

IR stealth technology is reducing or changing the IR radiation characteristics of the object in order to achieve low detectionable characteristics of the object. It can reduce and absorb the IR radiation energy of the object by improving structure design and applying the principle of IR physics, thus it's difficult for IR detection devices to detect the object. The preliminary research and early development of IR stealth technology was accomplished in the late 1970's. It had important break through and entered the practical period from basic research period. Since 1980, IR stealth technology has been widely applied in the new weapons of foreign army, navy and airforce. At first, the principles of IR stealth are analyzed, then its application and developing tendency are studied.
