浅谈现代战斗机的红外隐身技术

雷达隐身技术、电子战、红外探测技术和战斗机高机动性等因素使红外隐身技术变得更为重要。本文讨论了现代战斗机的红外隐身技术。目前在现代战斗机上采取的红外隐身措施，主要是综合使用冷却、屏蔽、遮挡和红外隐身涂料等技术手段，达到消除或模糊目标与背景之间的温差，降低目标红外辐射的强度和亮度，限制目标红外辐射的方向等目的。这些隐身措施对减小现代战斗机的红外辐射特性有一定的作用，其作用大小与战斗机的用途和性能有关；但因战斗机需大功率发动机和高速飞行，一般说来目标的红外辐射特性仍是相当明显。

About Infrared Camouflage Technology of Modern Fighters

Infrared camouflage technology has become more and more important because of the development of radar stealth technology, electronic warfare, infrared camouflage technology and high-mobility of modem fighters.Based on published papers, the main infrared camouflage technologies currently used in modem fighters are discussed in the paper. These technologies include cooling, shield,cover and infrared coating etc. to eliminate or reduce the difference of temperature between objects and background, to reduce the infrared radiation intensity and brightness of objects, and to direct the infrared radiation of objects. The camouflage technologies can reduce infrared characteristics of modem high-mobility fighters in a certain degree and their effectiveness defend on the mission and performance of modern fighters. Because of powerful engines and high-mobillity flight, infrared radiation of modern fighters is still quite strong.
