摘要
介绍了一种脉冲发动机直接力控制的弹道修正方案,分析了脉冲修正弹药制导律设计特点,指出纵向导引律是设计的首要问题.提出了射程预测导引的概念,其核心问题是建立射程预测方程:通过理想弹道和典型扰动弹道的解算获取样本点,建立射程和中间弹道参数的多项式模型,采用回归方法求取多项式系数.仿真表明,采用该导引方法进行纵向修正后,弹丸的纵向落点标准误差从123 m下降到21 m.
A trajectory correction scheme based on the directive force of pulse jet was introduced,and the correction guidance law of pulse jet was analyzed.It was pointed out that the longitudinal guidance law is the chief task.The concept of range prediction guidance was brought forward,and the kernel is the foundation of range prediction function,i.e.,getting samples by solving ideal trajectory and typical disturbed trajectory,setting up the polynomial model of the range and the intermediate trajectory parameters,a...
