| 摘 要： | 为了进行声相关计程仪(ACL)仿真研究,结合K irchhoff近似和R ay le igh-R ice近似散射模型,根据ACL垂直发射波束的特点,在掠射角90°附近,利用已发表的海底散射实验数据与APL-UW散射模型及L am bert公式的理论计算结果相比较,基于K irchhoff近似的散射模型与实验数据具有很好的一致性,仿真结果证明,由于不同类型海底沉积物引起的体积散射在上述情况下是可以被忽略的,这将大大简化进行声相关测速仿真研究的海底建模过程。

| Abstract: | To obtain scattering models for acoustic correlation logs(ACL) simulation,the published measurement data is compared to the predictions of the Kirchhoff approximation and Rayleigh-Rice approximation scattering models and Lambert'law formula at a grazing angle near.The Kirchhoff approximation model for the water/sediment interface roughness is found to be conformance with experimental results.The computed results show that the volume scattering can be negligible and the modeling procedure will be simplified. |
