导弹弹体转速变化范围较大,会给导引头有效跟踪目标带来困难。为消除弹体转速变化对导引头跟踪目标的影响,文中提出一种导引头自适应弹体转速的设计方法。这种设计方法不但可以在弹体转速变化的情况下实时提供正确的目标方位信息,而且可以有效提高导引头的进动效率,实现导引头在自旋弹体下消除转速变化对其影响,达到导引头精确跟踪目标,保证导弹命中精度的目的。

The change of projectile speed is difficult to track the target effectively. To eliminate the projectile speed changes affect seeker tracking target. An adaptive method is presented for the large range of projectile speed change. This method can not only under the projectile speed variation in real time to provide accurate information on the range, and effectively improve the efficiency of precession of seeker. Realize the seeker in the projectile spin eliminate change speed of its effects, precise tracking target, ensure the missile accuracy.
