| 摘 要： | 在水下目标强度的测量中，当目标体接近水面时，与自由空间情形相比，声波受到水面的散射及多径作用使回波强度发生变化。文章应用波动水面的平均反射系数计算方法，得出符合高斯分布的粗糙水面的反射系数与声波频率、入射角度的变化关系。计算了在四种不同传播路径作用下目标强度的结果。最后通过水池试验，验证了在高瑞利系数下结果的正确性。 |

| Abstract: | In the experiment of the underwater target strength measurements,when the target close to the water surface,compared with the target in free space,the measurement of target echo is affected by the scattering form the water surface.The calculation of the coherent reflection coefficient of the rough water surface which has a Gaussian spectrum is used,and in the case of the rough water surface which has a Gaussian spectrum,the change of the specular reflection coefficient with the frequency and incident angle ... |
| Keywords: | fluctuation of the water acoustic scattering target strength |
