具有末制导搜索能力武器对概略目标的区域射击方法研究

摘要

区域射击方法可以充分利用具有末制导搜索能力武器的性能特点,有效搜捕并打击未准确定位目标.现有方法采用统计模拟法分析打击过程与毁伤效能,主要针对散布服从正态分布的目标,而对于误差情况更为恶劣的概略目标缺少深入研究.区域射击方法包含武器数量计算以及瞄准点配置两个核心问题.对于服从均匀分布的概略目标,通过建立并分析毁伤概率模型,求解最优射弹散布密度函数,构建预估校正方法,计算使给定瞄准点配置对应毁伤概率达到预定要求的武器数量;以毁伤概率上界为目标,提出瞄准点配置的优化求解方法.参考国外主流装备技术参数,通过仿真计算,验证了方法的有效性与时效性,并与现有方法进行了对比,结果表明所提方法优化程度更高,并且能够使区域射击方案达到预定毁伤概率的要求.%By taking advantages of the technical feature of the terminal guided weapon with search ability,area shooting method can search and attack outlined target effectively.The current researches analyze the shooting process and kill probability with the statistical simulation method,mainly concentrating on normal distributed target rather than the outlined target with larger errors.Area shooting can be subdivided into two basic issues:weapon amount calculation and aiming point configuration.To the outlined target with uniform distribution,the optimal weapon dispersion density function is deduced by constructing kill probability model,and a predictor-corrector method for calculating weapon amount is established,whose corresponding kill probability can reach the predetermined requirement.By setting the kill probability upper bound as index function,a solution for aiming point configuration is proposed.According to the technical details of contemporary weaponry,the numerical simulation is conducted to verify the validity and timeliness.Comparison with the existing method demonstrates the advantages of our method both in the extent of optimization and in the effectuation of satisfying predetermined kill probability.
