A Test Computation Mcthod of Guidance Error Probability Density for Missile

导弹的制导误差概率密度试验计算,是确定导弹目标杀伤概率的基础,在工程中具有重要应用价值。一般在飞行试验中,导弹的弹着点散布,散布中心主轴与量测坐标轴不平行,使得弹着点横向坐标与纵向坐标线性相关,提出了根据导弹飞行试验数据,确定弹着点散布中心主轴方向的计算方法,以及系统误差和随机误差计算方法,为导弹制导误差概率密度计算,提供了计算手段。

The computation method of guidance error probability density for missile is very important in engneering. which provides the foundation for kill probability, In qualification test, the point of impact of missile is spread, the principal axis of centre of spread is generally not paralleled with measure coordinates axis, namely horizontal coordinate and vertical coordinate of the point of impact of missile is linearly dependence. Based on qualification test data. a method is presented, which can calculate the principal axis of centre of spread of missile. Furthermore computation method of system error and random error of guidance is propoised, The presented method can be easily used in computation of guidance error probability density.
