红外制导是当代红外技术的重要军事应用之一。从四十年代中期开始,至今已有近四十年的历史。它自身的发展大概可以分为三个阶段,这三个阶段又是与红外技术本身,特别是红外探测器的发展紧密相连的。从四十年代中期到五十年代中期可算作第一个阶段,这期间,红外末制导主要是点源探测,尾随攻击方式,红外元件基本上是非致冷型硫化铅,工作波段1～3μ,由于该波段受背景和气象条件的影响较大,故主要用于空对空导弹的末制导,尾随攻击锥角大约90°。抗干
Infrared guidance is one of the important military applications of contemporary infrared technology. Since the mid-1940s, it has been nearly 40 years old. Its own development can be roughly divided into three stages, which are closely linked with the development of infrared technology itself, especially infrared detectors. From the mid-1940s to the mid-1950s, it can be regarded as the first stage. During this period, the infrared end guidance is mainly point source detection and trailing attack. The infrared components are basically non-cooling type lead sulfide. The working band is 1 ~ 3μ Since this band is greatly affected by the background and meteorological conditions, it is mainly used for the terminal guidance of an air-to-air missile with a trailing attack cone angle of about 90 °.
