首发时间:2009-01-14
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率设计特点,指出纵向导引率是设计的首要问题。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123m下降到21m。

Range Prediction Guidance Law for Pulse Jet Correction Projectile
Abstract:A trajectory Correction Scheme based on the directive force of pulse jet is introduced and the specialty of pulse jet correction guidance law is analyzed, and it is pointed out that the longitudinal guidance law is the chief task. The concept of range prediction guidance is brought forward in witch the kernel is the foundation of range prediction function: getting samples from simulation trajectory without or with typical disturbances, setting up the polynomial model between the range and the trajectory parameters of the sample points, and then getting the polynomial coefficients by regression. The numerical simulation shows that with this correction guidance law, the longitudinal standard error of the projectiles falls from 123 meters to 21 meters.
Keywords: pulse jet trajectory correction range prediction
