摘　　要：针对助推滑翔导弹快速发射的任务需求,提出了一种基于诸元数据库的助推段弹道诸元快速解算方法。首先,利用滑翔段弹道解析估算,得到影响射程的助推段终端参数。然后,对助推段终端空域进行网格化剖分,针对每个高度速度特征点,利用牛顿迭代法对弹道诸元进行解算并形成诸元数据库。最后,基于诸元数据库利用临近点双线性插值方法计算弹道诸元并开展了仿真验证。结果表明,所提方法在保证良好精度的同时可以大大缩短弹道诸元计算时间,从而提高弹道设计的效率。In order to meet the mission requirements of the boost-glide vehicles’ rapid launch, an efficient calculation method for firing data in the boost phase based on the database was developed. Firstly, the terminal parameters in boost phase which affect the range were obtained by analyzing the estimation of glide phase. Then, a range of terminal states in boost phase were meshed and divided. At each height and velocity characteristic point, the Newton iteration method was used to solve the firing data and the database was formed. Finally, the firing data was calculated by near point bilinear interpolation method based on the database and the simulation verification was carried out. The results show that the proposed method can greatly shorten the calculation time of firing data while ensuring a good accuracy, thus improving the efficiency of the ballistic design.
