| Abstract: | 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. |
