简介:近代雷达寻的制导系统,多数按照比例导引规律工作,即是说满足于:式中θ是导弹速度矢量的转动角速率;是目标视线转动角速率;N 是有效导航比。该公式的物理含意是:雷达导引头适时地测量导弹目标间的视线角变化速率,并且利用这个信息制导导弹,以获得导弹飞行路线在成比例的角速率下变化。因此雷达导引头的基本 Introduction: In modern radar guidance systems, most of them work according to the principle of proportional guidance. That is to say, they satisfy: where θ is the rotational angular velocity of the missile velocity vector; is the angular rate of rotation of the target line of sight; and N is the effective navigation ratio. The physical implications of this formula are: The radar seeker measures the rate of change of line of sight between missile targets in due course, and uses this information to guide the missile to obtain a change in the missile’s flight path at a proportional angular rate. Therefore, the basic radar seeker
