激光制导炸弹弹道拟合模型与算法

The Research on Fitting Trajectory Model and Algorithm of Laser-guided Bomb

由于激光制导炸弹的弹道受控,其弹道复杂,采用传统炸弹弹道的拟合方法达不到精度要求。从抛物运动的角度提出了两种对激光制导炸弹弹道拟合的方法。第一种方法对一般的抛物运动标准解引入修正项实现对激光制导炸弹弹道的拟合。第二种方法对激光制导炸弹的攻击运动过程进行分析,然后,引入加速度修正项对激光制导炸弹弹道进行拟合。通过大量的仿真表明这两种方法的拟合精度均很高。相比较而言,第二种方法精度更高。

This paper,from the point of projectile's movement,present two methods for the trajectory of laserguided bomb in the belief that,by the fitting method of traditional bomb,the fitting precision can't meet requirement for it is controlled and complicated.One method is to modify the standard result of the projectile's movement to fit trajectory.The other is to analyze the process of projectile's movement,then the trajectory is fitted by modifying the acceleration of gravity.Large amounts of simulations show that the two methods both render a very good performance in precision.In comparison,the latter method is better than the former.
