改进的运动目标预先标定轰炸瞄准方法

Improved pre-calibration bombing targeting method for moving targets

使用机载武器攻击运动目标是一个实用性强的研究问题,预先标定巧妙地利用数学方法解决了在信息不完备情况下对运动目标的精确轰炸问题,具备较好的工程价值。但当前方法存在过程环节多、标定/瞄准难度大等不足。研究了一种改进的预先标定轰炸瞄准方法,使用可操控的标定符号代替基于连续计算命中点原理产生的标定符号,提高了标定符号变化的规律性,降低了标定难度和瞄准难度;给出了新方法下的目标综合速度计算模型,结合弹道解算和目标运动假设,建立瞄准符号的解算方程。最后针对典型的运动目标进行了仿真分析,讨论了该方法的误差变化规律。

Using airborne weapons to attack moving targets is a practical research problem.The problem of accurate bombing of moving targets with incomplete information is solved by using mathematical method in pre-calibration.It is of great value in engineering application.However,the present method has many disadvantages,such as too many process links and the difficulty of both pre-calibration and aiming.An improved precalibration bombing trargeting method is proposed.The controllable calibration symbol is used to replace the calibration symbol based on continuously computed impact point principle,which improves the regularity of calibration sign change,reduces the difficulty of calibration and aiming,and gives the calculation model of the target synthetic velocity under the proposed method.Combined with ballistic calculation and the target motion hypothesis,the calculation equation of aiming signs is established.Finally,the simulation analysis of typical moving targets is carried out,and the law of error variation of the proposed method is discussed.
