摘要现代战争中, 坦克装甲车辆面临来自各方面的威胁, 其自身的装甲无法抵抗所有的打击, 特别是各种反坦克导弹。文章对针对坦克装甲车的穿甲弹、反坦克导弹等高速动能弹的拦截方法进行了分析,认为使用线性爆炸成型侵彻体(Linear explosively formed projectile, LEFP)是目前比较好的拦截方式,本文介绍其工作原理及过程、建立拦截模型、并且分析拦截概率。运用MATLAB对该数学模型进行仿真和分析,通过蒙特卡洛法将随机抽样的误差值加入标准量得到观测值,再利用最小二乘法进行拟合,计算LEFP发射时刻以及拦截概率。为LEFP拦截高速动能弹的新型主动防护系统的研制和使用提供技术支持和理论参考。60074

Title Analysis of Interception Probability for An Intercept System
Abstract
In modern war, tanks and armored vehicles facing from various threats, its own armor cannot resist all blow, especially all kinds of anti-tank missile. The article for intercepting method penetrators, anti-tank missile, high-speed projectile armored vehicle is analyzed, that the use of linear explosively formed penetrator (Linear explosively formed projectile, LEFP) is the better the interception mode, this paper introduces the working principle and process, establish the interception model, analysis and interception probability . MATLAB is used for simulation and analysis of the mathematical model by Monte Carlo method, the errors of random sampling values to the standard amount of observation value, then using least squares fitting, calculation of LEFP emission time and the probability of intercept. Provide technical support and theoretical reference for development and use of new active protection system of high-speed projectile of LEFP intercept.
Keywords Linear explosively formed projectile Interception probability Simulation The Monte Carlo method The least square method
