驾束制导军事上一种控制武器运动的制导方式,通常是使用在各种导弹系统上,作为制导的讯号以雷达激光为主,是一种较为简单的制导方式。

特性

驾束制导常被列为命令制导的一类,事实上,两者有相当的差异;命令制导导弹内的制导系统只需执行接收命令的工作,而驾束制导的导弹则还要感测其在波束中的位置,从而指导导弹保持在波束中央。

发射载具在标定目标之后,将雷达发射的制导讯号持续照射在目标上,发射载具或者是提供制导讯号的雷达必须配合目标的移动而保持波束的位置。导弹发射之后会进入制导波束当中,如同跟随一条看不见的线路飞行,而在这个线路的末端就是导弹要攻击的目标。

由于发射制导讯号的雷达必须稳定波束的改变,使用于空对空导弹方面,对飞行员的工作压力较大,除了少数早期的产品以外,大多数的驾束制导防空导弹系统为陆上或者是舰上系统。当半主动雷达制导技术成熟之后,由于驾束制导系统的同时目标接战数目较少,逐渐由半主动制导取代。
