摘　　要：针对非均匀面目标毁伤效果Monte-Carlo计算方法在子目标位置发生变化后需要重新进行计算,计算时间长的问题,提出基于目标毁伤效果函数的非均匀面目标毁伤效果分析方法.函数从毁伤概率角度反映弹药对目标毁伤效果在空间中的分布,不受子目标位置变化影响.融合信息学与积分变换将目标毁伤函数积分计算转化为矩阵卷积计算,并借助二维快速傅里叶变换将计算复杂度由O(N2)降低至O(Nlb N),计算时间由分钟级缩短至秒级.针对特定作战场景、不同打击方案下大质量整爆弹对典型机场停机坪目标的毁伤效果进行了实例验证,验证了计算方法的可行性.Since the traditional damage effect calculation method of the non-uniform area target needs to re-do the Monte-Carlo simulation after the position of sub-target changes,a damage effect modeling method of area target based on the damage effect function was proposed.This function reflects the distribution of ammunition power field in space from the perspective of damage probability,and is not affected by the position change of subtargets.Drawing on the idea of informatics and integral transformation,the convolution integral calculation of the damage effect function was converted into matrix convolution calculation,and the computational complexity was changed from O(N2)to O(NlbN)with the help of two-dimensional fast Fourier transformation,which greatly improved the calculation efficiency and reduced the calculation time from the minute level of Monte-Carlo simulation to the second level.The damage effect of integral blasting missile warhead on typical airport apron targets under specific combat scenarios and different strike schemes was empirically studied,and the feasibility of the calculating method was verified.
