摘　　要：高质量的射击修正可提高发射命中概率。提出了一种基于系统共同误差极大似然(ML)估计的炮兵射击修正方法。炮兵武器系统的射击误差分解为系统共同误差和各级子系统独有误差。在它们均服从参数已知的正态分布条件下,结合测得的射击误差,给出了系统共同误差的ML估计公式;在此基础上,给出了逐次修正量序列的计算公式。仿真结果表明,该方法比传统修正方法更有效。High-quality firing correction can improve the firing hit rate. A firing correction meth- od for the artillery weapon system based on the maximum likelihood （ML） estimation is pro- posed. The firing errors of the artillery weapon system can be decomposed as system common er- rors and subsystem particular errors of different levels. These components are assumed to follow normal distribution. The calculation formulas of system common error estimated by ML estima- tion method are given by using measured firing errors. On this basis, the calculation formulas of firing correction sequence for artillery weapon system are given. Simulation results show that the correction method is more efficient than traditional methods.
