摘要
针对传统通过观测鱼雷轨迹判断鱼雷命中目标位置的方法存在较大误差的问题,采用几何分析法,首先剖析了传统观测鱼雷轨迹法的数学原理,然后建立了直航鱼雷转角射击的数学模型,最后研究了由鱼雷与目标相遇转换为鱼雷轨迹首端与目标相遇的修正原理,建立了鱼雷速度修正量解算模型,并对修正过程可能导致的误差进行了分析。最后实例验证了该方法的可行性和有效性。
Considering the problem of traditional method through observed torpedo trail to estimate the torpedo’s hit position could bring big error. Through geometrical analysis,the paper analyzes the mathematic theory of traditional method firstly,then the paper set up the mathematical models of bearing attack for Straight Running Torpedo,At last,the paper researches the revise theory of revise the torpedo encounter target to torpedo pre-trail encounter target,seting up the calculation models of the torpedo velocity revise,and analyzed the revise error. Finally an example verify the feasibility and validity is proven.
