The Study on Improvment of Firing Accuracy of Rocket-projectile Using Impact Point Predication Guidance Law

文中对利用落点预测制导律提高火箭弹射击精度的方法进行了研究。首先论述了落点预测制导律的基本原理、偏差矢量E的获取方法,脉冲发动机点火的逻辑;其次,给出了特定条件下的脉冲发动机控制力修正能力决策表;最后,进行了射击仿真实验。结果表明,利用落点预测制导律可以显著提高火箭弹射击精度。

The method with which the firing accuracy of a rocket-projectile can be improved by the impact point forecast guidanee law（IPFGL） has been studied. Firstly, the IPFGL＇s theory, the method of miss distance E,and individual lateral pulse jet firing logic was introduced. Secondly, the correct ability decision-making figure about individual lateral pulse jet was provided. Lastly, the firing simulation experimentation was done. The simulation result shons the firing accuracy of a rocket-projectile can be significanting improved by.
