摘　　要：能使自导鱼雷获得最大发现概率的射击提前角称为有利提前角。采用几何解析法求解有利提前角时,求算公式不是显解形式,需要迭代法解算。该文求算的自导鱼雷有利提前角,是以鱼雷自导扇面与目标的相遇点作为基础,算法是显解形式,不需要进行迭代法解算。通过计算机编程计算发现,两者求得的值相差不大,特别是在雷速大和敌速较小的情况下,二者数值非常接近,但计算时间,后者明显快于前者。Favor of early angle is the shooting early angles which enable guided torpedo get the max finding probability.When calculating the favor of early angle,if adopting the geometry analytic method,the calculation formula isn＇t explicitly formed.So,iterative calculation is needed.The favor of early angle of sound-guided torpedo was provided based on the meeting point of torpedo guided fans and the target.The algorithm is explicitly formed,so the iterative calculation isn＇t needed.According to the computer programming and computation,the value got by two methods is similar.Especially,when the speed of torpedo is fast and the speed of target is slow,the value of two methods is very similar.But,the speed of the latter is obviously faster than the former.
