基于落速预测理论的子母弹抛撒高度优化算法
|
摘要
为了更准确地控制子母弹抛撒半径,根据落速预测理论设计了一种子母弹抛撒高度优化算法,在母弹飞行至最大理论抛撒高度前计算落速,根据计算结果重新修订装订抛撒高度,然后在该高度上抛撒子弹。通过仿真计算表明:应用该算法可以明显地减小子母弹抛撒半径的误差,有利于精确控制子母弹抛撒半径。
Based on the velocity-forecasting theory,a novel optimal calculation method of dispersion height is proposed to control precision of dispersion radius. When the missile is above the ejecting height, a new ejecting height which calculated by the optimal calculation method is set into the system of missile. The missile will eject the bullets at the new height. At last, the efficiency of the optimization method which is proposed to improve precision of dispersion radius is verified by a simulation example.
