红外制导系统的发展已有三十余年的历史,系统设计技术有了很大进步,本文将回顾曾引起系统设计革新的红外技术发展,同时根据战术使用要求的变化和技术进步,分析了如何改进下一代制导系统的设计。众所周知红外制导系统具有一些特有的优点。这些优点是由于系统是被动的,它不需要发射机,使用起来不易被敌人发觉;部件设计简单,体积小,重量轻,价格便宜;被动红外系统不易被干扰;具有较高的导引精 The development of infrared guidance system has been more than thirty years old, and the system design technology has made great progress. This article will review the development of infrared technology that has caused the system design innovation. At the same time, according to the requirements of tactical use and technological progress, Improve the design of the next generation guidance system. It is well-known that infrared guidance systems have some unique advantages. These advantages are due to the fact that the system is passive, it does not require a transmitter and can not be easily detected by the enemy. The parts are simple in design, small in size, light in weight and cheap in price. The passive infrared system is not easily disturbed.
