摘要: 为了研究声自导鱼雷搜索波束对搜索效率的影响, 以噪声掩蔽下主动声呐方程为基础, 结合立体角计算公式, 推导出声自导鱼雷搜索波束宽度和自导作用距离的关系式。根据蛇行搜索弹道特点建立蛇行弹道下的搜索面积模型, 定量分析了不同因素对鱼雷搜索效率的影响, 确定了最佳搜索波束宽度范围在15°~25°之间, 所得结论可供声自导鱼雷基阵设计和作战使用参考。Abstract: To understand the influence of acoustic homing torpedo searching beam on searching efficiency, the relation between torpedo searching beam width and homing range is derived based on the active sonar equation and the solid angle formula. According to the characteristics of snake trajectory, a model of torpedo searching area is built. The influences of various factors on torpedo searching efficiency are quantitatively analyzed, and the optimized beam width range from 15°to 25°is determined. This study may provide a reference for design of sonar array and operational application of an acoustic homing torpedo.
