摘　　要：针对鱼雷自导作用距离不确知情况下的有利提前角解算问题,首先分析自导作用距离对鱼雷射击的影响,指出当鱼雷的实际自导作用距离小于其装订值时,解算得到的有利提前角会偏小,并会导致鱼雷的发现概率明显降低。其次定义了鱼雷的加权平均发现概率,在此基础上提出了一种最大化加权平均发现概率的有利提前角解算方法。然后基于最大熵原理,给出了鱼雷实际自导作用距离的2种最大熵分布模型,得到了该分布模型下的有利提前角求解公式。最后通过仿真得到了鱼雷自导作用距离不确知情况下的有利提前角。In order to solve the favorable advance angle in the case of an uncertain homing range of torpedoes,the influence of homing range on torpedo firing was first analyzed.It was pointed out that when the actual homing range of torpedoes was less than its binding value,the favorable advance angle obtained from the calculation became smaller,and the probability of torpedo discovery was significantly reduced.Secondly,the weighted average discovery probability of torpedoes was defined.On this basis,a favorable advance angle calculation method was proposed to maximize the weighted average discovery probability.Then,according to the principle of maximum entropy,two maximum entropy distribution models for the actual homing range of torpedoes were given,and the formula for solving the favorable advance angle under this distribution model was obtained.Finally,the favorable advance angle in the case of an uncertain homing range of torpedoes was obtained through simulation.
