圆概率偏差

定义了命中区域圆概率偏差（ACEP）、区域要害指数、区域命中概率及命中要害指数等概念；

Firstly , the area circular error probability ( ACEP ), area vital index , area hitting probability and hitting vital index are defined as the concepts of coefficients for the optimal selection method .

圆概率偏差的测定与检验

Estimation and Test of Circular Error Probability

导弹的落点精度（以圆概率偏差表征）是一项重要的战术技术指标。

The accuracy of the fall points is one of the important performance indexes of missile systems .

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。

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 .
