摘要
针对大口径舰炮射击的弹道特性,提出了一种简化的弹道滤波方法。通过对弹道进行分段线性处理,使得状态方程和观测方程为线性形式并进行了仿真试验。仿真计算结果表明,该方法简化了模型,可以有效降低运算时间、提高计算精度且易于工程实现。
In view of the ballistic behavior of major caliber naval gun,a simplify method about ballistic filtering is proposed.The method has linear state equation and linear measurement equation by supposing the projectile fligts in uniform speed during a very short time.The simulation result indicate that the simplify method simplifies the model.It can reduce the caculating time effectively,improve the accuracy and be easy to engineering realize.
