鱼雷攻击体目标命中效果仿真方法

摘要

鱼雷的命中效果一般用命中参数来表征.用点源目标评价鱼雷命中效果只有单一脱靶量,且实航试验中为避免鱼雷与声靶或真实目标相撞,常采取规避措施,难以得到实际命中参数.针对此,文中提出一种用体目标评价鱼雷命中效果的仿真方法,建立了鱼雷跟踪目标过程的全弹道数学模型和描述体目标几何特性和命中参数的数学模型,并进行了鱼雷攻击体目标效果的仿真计算和分析.仿真结果表明,鱼雷命中效果与目标几何特性、目标速度、雷目相对态势等因素有关.该方法为评价鱼雷命中目标效果提供了一种有效的手段,可为鱼雷弹道和导引规律的优化设计提供参考.%The hitting effect of a torpedo is usually represented by the hitting parameters. However, evaluating hitting effect via point target can only get the miss distance, and eluding measures are often taken to prevent a torpedo colliding with an acoustic target or a real target in sea trial, the actual hitting parameters are difficult to be obtained. In this paper, a simulation method for evaluating torpedo hitting effect with body target is presented. A whole trajectory's mathematical model of torpedo tracking target process and a mathematical model describing the geometric characteristics and hitting parameters of the body target are established. Simulation calculation and analysis on the hitting effect of a torpedo attacking body target are carried out. Simulation results show that the torpedo hitting effect is related to the geometric characteristics of the target, the target velocity, the relative situation between the torpedo and the target, and so on. This method may provide an effective means for evaluating torpedo hitting effect, and may provide a reference for optimization designs of torpedo trajectory and guidance law.
