摘　　要：针对声自导鱼雷直进射击时通过弹道简化快速计算鱼雷射击参数,导致的鱼雷命中结果系统误差问题,采用几何分析法,首先,分析了声自导鱼雷直进射击原理,建立了声自导鱼雷自导搜索扇面在目标航向线的遮盖范围解析计算模型;然后,依据声自导鱼雷直进射击弹道过程,建立了鱼雷命中结果误差的解析计算模型,并分析了该误差对鱼雷捕获目标效果的影响;最后,研究了消除系统误差的提前角修正方法。通过实例论证了修正方法的可行性和有效性。In this paper, the straight-forward shooting mathematical principle of sound-guided torpedo was analyzed, the calculating models of obscuring target scatterance were established, and analytic models of hit result error were established in accordance with the trail of sound-guided torpedo through geometrical analysis. Besides, this paper analysed the influence of hit result error; moreover, the torpedo lead angle revising method to eliminate systematic error was researched. Example result demonstrates the feasibility and validity of the proposed method.
