本文提出了用显示现时发射炮弹经过弹丸飞行时间后在空间踪迹以及目标的将来位置的原理来克服航空火力控制领域中过去示迹线瞄准申的提前开火问题.文章首先对这种原理进行了详一的理论推导,其中包括弹丸预测及目标预测两部分,而目标预测是建立在目标加速度为一阶相关率稳随噪音下的.然后给出了攻击机作等速圆周运动的简化计算公式. In this paper, we propose to overcome the problem of pre-firing in the past by using the principle of showing the trajectory of the projectile in the space after the projectile flight time and the future position of the projectile in the past.First, this principle is described in detail A theoretical derivation, which includes the projectile prediction and the target prediction, is based on the target acceleration of the first-order correlation coefficient under the steady noise.And then a simplified calculation formula for the attacker to make the constant velocity circular motion is given.
