| 摘 要： | 根据Mie散射理论，在认为气泡不相干的情况下，计算了单个气泡在不同散射方向的散射强度，得出舰船尾流某个横截面上气泡群的光散射特性。计算结果表明，气泡群的后向散射增强非常明显；舰船尾流横截面上尾流中心气泡的散射强度远大于尾流边缘处的散射强度，说明利用舰船尾流中气泡与背景海洋中的气泡对光散射的差异来作为鱼雷自导的一种手段是可行的。

| Abstract: | Based on the Mie scattering theory, the bubble scattering intensities at different scattering direction were calculated and the scattering properties on one cross section of the ship wakes was obtained with the assumption that the bubbles were not relevant to each other. The results indicate that the back scattering enhancement by bubbles is very clear, and the bubble scattering intensity on the midline of one cross section of the ship wakes is much greater than that on the fringe of the wakes. The feasibility of the light wake homing torpedo by using the difference of the scattering intensity of bubbles in the ship wake and those in the surrounding sea is testified. |
