一、引言;在研究自导鱼雷射击问题时,目标的相对移动线是很有用的。它的使用,可以简化鱼雷与日标之间相对位置的分析与计算。而鱼雷与目标的相对位置决定了目标被自导装置发现与否。在鱼雷与目标均做等速直航的情况下,相对移动线的求取用简单的作图就可以解决。而在目标作等速直航的情况下,追线(即鱼雷的运动方程)微分方程已经解决,然而在一般情况下,也就是目标以非匀速的曲线运动,而鱼雷也以非匀速的曲线运动时,相对移动线又是一种怎样的轨迹呢?文献中指出,在任意曲线运动下,鱼雷和目标的相对轨迹可由公式
I. INTRODUCTION In the study of self-guided torpedo shooting, the relative line of motion of a target is useful. Its use simplifies the analysis and calculation of the relative position between the torpedo and the Japanese standard. The relative position of the torpedo and the target determines whether the target is found by the self-guided device or not. When the torpedo and the target are doing a constant speed direct flight, the relative movement line can be solved simply by plotting. In the case of the goal of constant speed direct navigation, chase (that is, torpedo equations of motion) differential equations have been resolved, but in general, that is, the goal of a non-uniform curve of movement, and torpedoes also non-uniform curve Movement, the relative movement of the line is what kind of trajectory it? In the literature pointed out that in any curve movement, the relative trajectory of the torpedo and the target by the formula
