运动靶标几何半径的确定方法

Calculation Method of Geometrical Radius of Moving Targets

首先,利用相对坐标变换,将三维命中精度问题转化为二维命中精度问题,并给出利用二重积分近似求得命中概率的简便公式;其次,利用命中概率建立了检验效率函数,并分析了效率函数的特性,在控制2类风险的前提下,用效率函数建立了检验公式;最后,根据检验公式的拒绝域,对目标圆柱半径进行分析,给出了运动目标圆柱(靶标)半径的确定方法。有效地避免了对检验结论的争议,为导弹命中精度试验的定性定量分析提供了理论依据,对导弹命中精度的检验问题具有重要的指导意义。

Firstly,three-dimension hit accuracy can be converted to two-dimension hit accuracy by means of relative coordinate transformation,and a simple formula is given to acquire hitting probability by using double integral approximation. Secondly,an inspection efficiency function is established using the hitting probability,characteristics of the efficiency function is analyzed,and check formula is established on the premise that two types of risk are controlled. Finally,according to refused domain of check formula,cylinder radius of moving targets is deduced and the method for determining the cylinder radius is put forward,solving the ambiguity of inspection conclusion,providing theoretical basis for quantify and qualitative analysis of missile hit accuracy test. The article conclusion is of great significance.
