摘　　要：传统弹道外推方法采用质点弹道方程进行外推,当外推距离过长可能会产生外推精度降低的问题,针对此问题,提出了基于遗传算法的弹道外推方法。从六自由度弹道方程入手,对只有位置和速度数据的雷达弹道测量信息进行分析处理,利用相邻测量点的弹道连续性,应用遗传算法实时辨识弹丸姿态角,建立了基于遗传算法的六自由度弹道外推方法,并外推弹道落点。仿真与试验的结果表明,该方法有效和可行。方法也可扩展到四自由度、五自由度等其他模型的弹道外推,可为准确外推弹丸落点和提高火控精度提供新的技术支持。The traditional ballistic trajectory extrapolation method uses the point mass trajectory equations to extrapolate and the extrapolation accuracy may be reduced when the extrapolation distance is too long.To solve this problem,a ballistic trajectory extrapolation method based on genetic algorithm is proposed.The radar trajectory measurement information with only position and velocity data is analyzed and processed starting from the six degree of freedom(6-DOF)trajectory equations.The genetic algorithm is applied to identify the projectile attitude angle in real time using the trajectory continuity of adjacent measurement points.A six degree of freedom trajectory extrapolation method based on genetic algorithm is established and the trajectory impact point is extrapolated.The results of simulation and experiment demonstrate the validness and feasibility of the proposed method.The proposed method can also be extended to other trajectory extrapolation models such as four degrees of freedom and five degrees of freedom and provides a new technical support for accurately extrapolating the impact point of projectile and improving the accuracy of fire control.
