摘要
为了分析激光半主动末制导炮弹的捕获概率,建立了含有简易惯性制导段的末制导炮弹飞行仿真模型以及判断末制导炮弹捕获目标的标准.研究了末制导炮弹全弹道的干扰因素及其对末制导炮弹纵向和横向散布的影响.利用蒙特卡洛法计算出激光半主动末制导炮弹捕获目标的概率.提出了提高捕获概率的改进策略,并通过仿真得到验证.结果表明,这种改进策略提高了末制导炮弹的捕获概率.
The target acquisition probability of the laser semi-active terminal guided projectile is analyzed and the flight simulation model is established including simple inertia navigation and the target acquisition criterion. The disturbance factors in the whole trajectory and influence on the longitudinal and lateral distribution are studied. The target acquisition probability of the projectile is computed using the Monte Carlo method. Some strategies are provided to increase the target acquisition probability by the simulation. The result of this study research shows that all the measures discussed can improve the target acquisition probability of the terminal guided projectile.
