子母弹最佳抛撒半径与导弹精度关系研究

Relation between the best separation radius of submunition and missile's precision

子母弹抛撒半径是评定子母弹打击效果的基础,而子母弹最佳抛撒半径与导弹精度密切相关,为了提高子母弹对目标的打击效果,需要确定子母弹最佳抛撒半径与导弹精度之间的确切关系。基于Monte Carlo模拟方法计算机场跑道失效率,分析了导弹精度和子母弹抛撒半径对跑道失效率的影响,运用黄金分割法求出不同导弹精度下的子母弹最佳抛撒半径,并用最小二乘法对导弹精度与子母弹最佳抛撒半径的函数关系进行拟合,通过比较得出二者近似为线性关系。

The separation radius of submunition is the condition of estimating the damage effect of submunition missile,and the best separation radius of submunition has close correlation with the missile＇s precision. So it is necessary to determine the relation between submunition missile＇s best separation radius and precision for raising the damaging effect of submunition on the targets. Based on disable probability of runway （DPR）, the best separation radius is gained with gold section method, the best combination between submunition missile＇s best separation radius and precision is found, and the functions are fit with least squares. Function relation of submunition missile＇s best separation radius andprecision is gained, which offers essential condition for firepower distribution and warhead design.
