一维弹道修正弹分段解算控制算法的研究

摘要

针对目前国内外一维弹道修正弹控制算法的研究,提出了一种弹道修正弹分段控制算法,利用改进的欧拉法进行解算弹道.该算法不同于其他控制算法的解算方式,将根据一组GPS数据一次性计算得到弹丸的落点坐标,改成了弹道分成若干段,在每段中进行解算,上一段的终点坐标作为下一段解算的初始坐标点,重新开始进行解算,利于解算很大距离的弹道飞行,减少弹道程序在弹载处理器中的解算时间,降低对硬件设计的要求,得到更全面的弹道飞行数据,进而提高弹丸的命中精度.%According to the study of control algorithm about the one-dimensional trajectory correction projectile all over the world,this paper presents a segmented control algorithm for trajectory correction projectile. This algorithm uses the improved Euler method to sole the trajectory. This algorithm is different from other methods of control algorithm. It uses a set of GPS date to divide the trajectory into several sections rather than to calculate the coordinates one time. In each of the solver, the coordinate point of end point is taken as the initial point of the next period,and then it can restart the solver. This method is beneficial to solving the flight of a great distance,and reducing the solve time of the ballistic missile program in the processor. The algorithm reduces the requirements for hardware design. It can receive more comprehensive flight date of ballistic,and then it can improve the accuracy of the projectile.
