| 中文摘要: |
| 海洋水声环境复杂性、多变性及其模型参数获取限制需要直接从实验数据中估计参数、评估模型。在水声物理框架下，利用信道物理规律、特性，基于数据估计/提取模型参数或模型(模型函数)，实现声场信息处理和控制具有学术价值和应用意义。本文综述波导不变量、格林函数提取和单边声场聚焦三种数据驱动声场信息处理与控制方法近年国内外相关研究进展。 |
| 英文摘要: |
| It is difficult to acquire full set of propagation model parameters due to complexity and variation of underwater acoustic environment. For these reasons, it is often required to invert/estimate parameters and evaluate model directly from experimental data. Data-derived acoustic signal processing and controlling of field method/technique using underwater acoustic properties or rules are of academic importance and application significance. In this paper recent developments on the waveguide invariant, Green’s function retrieval and single sided wave field focusing are briefly reviewed. |
