摘　　要：针对不同控制误差条件下弹丸的落点散布规律,分析了控制误差的表现形式,将控制误差近似描述为均值误差和抖动误差两项之和,设计了基于七自由度弹道模型的蒙特卡洛打靶仿真实验,得到了不同误差条件下修正弹的落点散布。仿真结果表明,固定鸭舵滚转角控制均值误差和固定鸭舵抖动误差都会增大修正弹落点散布,降低命中精度,且固定鸭舵抖动产生的影响大于控制均值误差的影响。该项研究可为固定鸭舵式二维弹道修正弹控制算法优化提供依据。To study the dispersion of trajectory correction projectiles in different control error conditions, the form of control error was analyzed and the error was described as a sum of mean component and dithering component. Monte Carlo simulation based on 7-degree of freedom trajectory model was designed to obtain the dis-persion under different error conditions. The results showed that the control error could increase the dispersion and reduce the hit accuracy, and the dithering component had greater effect on dispersion than the mean component.
