摘　　要：使用正交试验设计法,对某弹道修正弹的末段弹道进行了弹道参数优化设计。首先以攻角作为设计指标,分析确定了影响飞行稳定性的主要因素——脉冲冲量大小,并对其保证飞行稳定性的取值范围进行了研究;再以仿真计算的脱靶量均值和标准差为设计指标,分析了影响命中精度的主要因素及各因素的较优取值范围;最后对各参数水平的最优搭配进行了研究。仿真结果表明,根据计算得到的参数水平最优搭配可使脱靶量达到最小值。The terminal trajectory parameter optimization of trajectory correction projectiles was studied with orthogonal design. By making the attack angle as the designed parameter, the primary factor （the amount of impulse） which influences flight stability was analyzed, and the range of impulse value which ensures flight stability was researched. When making the computed average and standard deviation of the miss distance as the designed parameters, the optimal range of parameters which influences the hit precision was researched, and then the optimal combination of the parameters was studied with further computation. The simulation results show the optimal miss distance can be gained with the computed optimal combination of the parameters.
