中文摘要：
射击精度是导弹武器系统最重要的性能指标之一。建立了一种针对导弹武器射击面目标的精度评定方法，定义了命中面目标的精度指标命中区域圆概率偏差，设计了基于蒙特·卡罗积分法的命中区域圆概率偏差计算方法。理论推导和仿真分析表明，对命中面目标的精度指标定义合理，所设计的命中区域圆概率偏差计算方法简单、精确，可以用于导弹武器命中面目标的精度评定及瞄准点选取。
英文摘要：
Firing accuracy is one of the primary performance indexes for the missile weapon system. This paper proposes a method for estimating firing accuracy at the area target. Specifically, the hit area circular error probability （ACEP） is defined as an accuracy index for the area target and further a Monte Carlo integral method is designed for calculating ACEP. Theoretical analysis and simulation results show that the definition of firing accuracy is reasonable and the calculating method is simple and accurate. Therefore, conclusions obtained can be applied to the estimation of the firing accuracy and selection of the aiming point for missile weapons shooting at area targets.
