反舰导弹中/末制导交班点目标捕捉方法研究

为了提高对目标的捕捉概率,研究了反舰导弹中末制导交班点的选择问题。首先对中制导的散布概率区和目标的散布概率区建模,并得出反映中/末制导交班点捕捉概率大小的目标函数;在此基础上,利用遗传算法对该目标函数寻优,得出反舰导弹的最佳交班时刻和交班状态。全弹道数字仿真验证了该方法可有效地提高一类反舰导弹的捕捉概率。

Study on Capture Probability of Anti-Ship Missiles at Hand-Over Point

To improve the capture probability,the hand-over point of anti-ship missiles between midcourse guidance and terminal guidance was analyzed.The dispersion probability area models of missile middle guidance and targets were built respectively based on the dynamics and kinematics models of anti-ship missiles and targets.The object function,which represents the capture probability at the hand-over point,was obtained.The optimal time and states of the anti-ship missile at the hand-over point were obtained by the genetic algorithm.The full trajectory simulation proved this approach could improve the capture probability effectively.
