一、国外红外制导空空导弹的发展及现状:制导系统是空空导弹的一个重要组成部分,它的改进和发展在很大程度上促进了空空导弹的发展。在空空导弹发展的初期,国外曾在空空导弹上采用过驾束式制导系统,但是,由于这种制导系统限制了载机战术使用的灵活性,在目标作机动飞行时容易偏离波束而使导弹失控,后来不得不放弃驾束式制导系统而在空空导弹上采用比例导引方式的雷达自动导引制导来 I. Development and Status Quo of Infrared-guided Air-to-air Missile Abroad: The guidance system is an important part of air-to-air missiles. Its improvement and development have promoted the development of air-to-air missiles to a great extent. In the early days of air-to-air missile development, overseas had used over-the-beam guidance systems on air-to-air missiles. However, due to this guidance system limits the flexibility of carrier-based tactical use, the missiles can easily deviate from the beam when maneuvered to make missiles Out of control, and later had to give up drive-by-wire guidance system in the air-to-air missile guidance using proportional guidance method to guide the radar
